In the carlo HD's rhe company been me i nt crested t n ma nufacruri ng high explosives, Ac rhai time there were only a few variations of straight nitroglycerin dynamite. Service needs called for others with special char acteristics, and since then there has never been a time when powder chemists have nor been husv develop ing new formulas. The result is that there are now' 154 kinds and strengths of du Pont high explosives, to sav nothing about variations of cartridge size. And electric firing devices of different kinds, sizes and strengths make up a total of approximately 1,600. The figures merely stress the fact that there is some du Pont commercial explosive suitable for practically every blasting need. Wirh the production of du Pont smokeless powder the company at once became interested in chemical transformations of cellulose. Research opened the wav for an expansion of activities in this field and others related to it, and since the first decade of this century there has been a steady development of du Pont LiCilmeh lor tmmuku tui ing idlulose products and oilier* reqtrred in plant and fac ovv |aOvesses.

And the reason for that is easily explained: the industries served by the du Pont organization require quality product:*, and what is also important, they want them prepared to irect specific and exacting needs. The du Pont Company has been in business for more than 130 years and, in common with every other h k u iu facrurcr. its chief function has been to convert natural materials into more useful forms.

RYAN c Ok v k r al vc:irs ago, the Borough Council of Beach Haven, New Jersey, uxnsiruucd iuu: jetties of oak and chestnut piling along the beach to protect it from erosion. These jetties were plan red in double rows so rhat rhey formed oblong smic cures about six feet wide at:d of varying lengths, depending on conditions prevailing tm rhe beach at various points, The pilings were driven down twenty-live leer in die sard just as close together m possible. Some jerries had a hon ored pilings on each side and three or four across each end; others were constructed of vary ingnumhersdn veil in the same manner. Aficr Beach Haven had begun to cevelup rapidly as a summer resort, die authorities decided to erect stone jetties, ex rend mg our into the ocean for a distance of 100 or 125 feet to protect the beach against the ravages of rhe north easr storms. The wooden jetties or clusters of pilings on the beach were no longer necessary, and as it was desired to increase the she of rhe bathing beach and !o extend rhe boardwalk, the Council decided to remove die un sightly wooden projections, which had come to be a menace to bathers. Workmen endeavored to pull each individual pile our of the sand by the use of a large tripod and block and tackle, aided by a water jet, but this was found 100 costly. The largest number pulled out in a day, with several men, was twain-five, and rhe average was much less. This method therefore was abandoned as being impractical. Council then wrote the Technical Section of the du Pont Company af Wt]mington, Delaware, and requested that an explosives expert be sent to Beach Haven to look over rhe job. They wanted advice as to whether or not H would be prac tical to cut off the pilings at a safe distance: below the surface of the sand by the use of dynamite. Mr. E. T. Wolf and ihe wn ter accordingly made a trip to the resort and decided that the job could be done with explosives. We then asked the Mayor and Council to purchase a small quantity of dynamite and electric blasting caps, and to allow us to put in a "test day" to develop just what could he done. 'This res: was so .satisfactory rhat we were authorized iu order the necessary materials to complete the job. The result of the test day's work, using 60 per cen t Quarry Gd a tin dyna mite, l1 j hv S-iuch sticks, was rhe removal of 153 oak pilings, each rang ing from cigb.1 to ten inches in diam eter. Eighty-two sticks of dynamite and about fifty elec?He blasting caps wiih K-fnot lead wires were used for that performance. Jr was then decided to use 60 per cent .Straight Nitroglycerin Dvnamiie and to try the propagated deionaoon method, whereby rhe shock of one explosion .sets oil other charges ill the same hue. This worked with com plete success and, due ro the fact that an electric blasting cap for every charge was rendered unnecessary, the cost was furrher reduced. Ir is of course impossible rn punch or dr'll a hole through loose sand ro place a charge of dynamite, for as soon as the punch bar or drill is with drawn the hole closes with the loose sand. Therefoie, it was necessary fo use a jet of water supplied from one of the local lire hydrants. Several lengths of lire hose were run from the hydranr to the jet, with a reducing coupler and a one and one-half inch hose about twenry feet long in be tween. The water jet device itself was constructed of a piece* ofone-inch pipe, ten feet long, with an elbow fitting at the top for the hose connection. The small hose, of course, was used only Jor convenience in handling; one man alone could not handle a jet direct]y connected ro a lire hose. Th c in ei h oil of I <),ling an d sh not: i ng was as follows: A supply of wooden Page Four J The DU PONT jV.dgd^nik lad), ten feet long and one and onehalf inches wide by three-quarters inch thick was procured from a local lumber dealer. For t lie rcgul arcbarges, two sticks of 60 per cent Straight Nitroglycerin Dvnaniile were bound to the cud of each huh with twine. For the detonating charge, three sticks were used, one of them primed with an electric blasting cap with eightloot wires. Eleven charges were planted against a Hke number of pil ings for each shot, 'flic primed charge was placed against the center pile and the two stick charges, without caps, were p!need against each of the five pilings extending on either side. All were placed as close its an imaginary center line drawn between piles as was possible. In placing the charges the jet is pointed down alongside the pile so th at the water pressure displaces the sand. The dynamite, lied to the end of the lath, then follows the jer down to whatever depth is desired. Wc marked each huh with blue chalk at a point six feet from the dynamite and were therefore certain of having our charges at a uniform depth. Upon the withdrawal of the water jet, sand i ni ined i a tel y ft 1 Is in an >u nd i: he ch urges and lath, and the dynamite becomes firmly embedded. By using this method and placing eleven charges each time, we were able to load, con nect and shoot 1500 piles in six and one-half days, or a dally average of 230 pilings. To save on the cost of explosives, each charge was conlined to a quan tity sufficient, to cut die piles off but not to displace them entirely from the sand. If they were blown completely free, they would be washed out to sea. This was not desirable, for the timber was needed for use in the local incin erating plant. Accordingly, a chain Was hooked around the piles, and a horse was used to pull them out and drag them away to a safe place. The total cost of cuffing off the 1500 piles was 26F2 cents each. This includes the cost of approximately J 200 pounds of dynamite, 55b dearie blasting caps with eight-foot lead wires, and six and a half days' time for a blaster. After each shot a crater was lefr in the sand, and it was easy to ascertain A water Jet was used to displace sand so that the dynamite cartridges, tied to the end of a leftis, could be lodged, el the required depth, against the pile to be cut off A S'* Only one charge at the middle i>f fh*1 t`n wtrj primed with on b/nifjncj cop. tsuf fit rti'lc-natinn set off five charges an each tide. Thus, eleven pilings were blown at one "shat" that each pile was cut off clean, although there would occasionally be one that needed a small extra charge because a sliver of wood held it fast. These craters, due ro the anion of the water on the sand, filled in rapidly. We had originally advised Council tlmt we felt sure we could cur oil 175 piles per day. Our actual average, however, was well over 200, with 318 for the peak daw Consequently, the cost was less than had been csdma red. The authorities of Beach Haven have expressed their enrirc satisfaction with t lie wea k, and with the saving ol time and money result ing from the use of dynamite.

TTh e annual report ol the Bureau for tJie Safe Transportation of Explosives amt Other Dangerous Articles, re cently published, shows that for the ittiili cnnsecume year rhe railroads of rhe Lhnted Sraics amt Canada have carried dynamite and black powder without a single fatality or injury to anv person. Considering that in normal tunes rail shipments of these explosives amount m the aggregate to more chan 41X^000,000 pounds, the significance of this remarkable safety record at once becomes clear. Wc salute those who h.ne contributed to such a note worthy achievement. It has been made possible as rhe result of an intensive campaign of education among rail road employees and because there has been constant supervision and enforcement of rules by officials of a bureau, which was formed in 1906 under the auspices of the Amer ican Railway Association. From an article prepared by Colonel 13. W. Dunn, chief inspector of the Pure.in of Explosives, on the occasion of the Nobel Centenary last year, we gather die following information about the development of agencies that have a hand in shaping regula tions for safe shipment of these and oilier produces. In April, 39B5,mem bers of the American Railroad Asso ciation agreed that something should be done about :hc disastrous explo sions which were occurring, ami the suggestion was made that identical rules should be put intodicctby all the carriers and enforced by a new inspec tion agene v representing them. How ever, some ol rhe officials advocaied a federal supervision anc inspection service at the planrs, wdiicli was wholly unnecessary as events have proved. So the original plan was eventually adopted, and in June, 1907* the new inspection agency called the Bureau of Explosives came into being. One of the first important acts of the new agent was to bring railroad officials and explosives manufacturers together for a conference, which. Colonel Dunn refers to as "long, earnesi and, in the end, amazingly successful." In short, they agreed to a program of co-operation to insure the safe transport of explosives. As a result rules were prescribed setting fonh the respective duties of shippers and carriers and both parties assisted the Bureau of Explosives in secur ing uniform enforcement of the regulations. In 1908, through appropriate legis lation, i he Interstate Commerce Com mission was authorized to prescribe the rules and keep them up to date, and after passage of the bill and a public hearing, the Commission de cided to approve and promulgate the rules that the Bureau of Explosives and the shippers had prepared. Since then ail parties at interest have co operated and rhe results have been most gratifying. The remarkable ten-year record of safety in carrying explosives on thc rails is current reivy bur ti may he interesting to note Hurt fifty-two years ago railroad com panics were then undecided whether to accept dynamite as freight or not. At least rhe Pennsylvania Railroad Companv officials apparently had some misgiv ings about it, for a chemist, Charles B.

What would be rhe effect upon it of the jars incident to hauling, loading and unloading, and in transit; and of the concussion caused in coupling cars, and in smashing a car loaded with it, and in case of a wreck? His investigation of the plant pro cesses, described in some detail, evi dently assured him that the product was made in a proper manner, and that the risk of spontaneous decom position was very small.

In the Wenatchee Valley of that sta re, apple-tree plantings also go hac k to about 1876, and irrigation to about 1883- The extensive development in this section followed rapidly after irrigation di idles were opened during the decade ending about 1913- An apple-growing industry which was staned on a small scale in the Grand Valley of Colorado in 1880, has been developed extensively since 1890.

Starting with a small output of minor importance, this region now accounts for a substantial percentage oi the total commercial apple crop in the United States. The irrigated val leys especially favor the growth of trees producing heavy yields of stiperior-qtialiry apples. This, together with extensive machinery for han dling the fruit and modern methods of packing, distributing and market ing it, has placed the industry there in a most enviable position. Commercial apple growers, because of competition and the dcvelopmcnr of many new" districts, have generally adopted specialized planring, scien- tide cultural methods, and modern ways of distributing their products. They have found that it pays well to do so, for a long period of time is required before a return can be expected from a new orchard.

Such risks must be accepted, but orchardists are too wise to accept any rhat are susceptible t o human control, such as rhe ravages of insect pests anc fungous diseases. 11 is common knowledge that many insects and fungi have retarded the progress of apple growing, but San Jose scale and rhe codling moth arc ihc most serious menaces. This moth, which is of European origint is very destructive wherever apples aregrovvn the world over, font causes enormous losses. Known also us "apple worm," this insect feeds inside the frnir, and when infestation occurs early in the growing season, the fruit usually drops from the tree. In sections where codling moths are numerous, apples approaching maturity are frequently disfigured by worms causing small punctures in rhe skin. Thev may suc cumb to a poison sprayed on the surface, hut it is then too Late, the damage has been done. In warm, dry regions apple grow ers have ro cope wirh as many as four broods of the codling moth, and as a rule it requires seven spray applica tions io avoid serious infestation.

So in tlie well equipped radio home today, you are apt to find in the playroom a MX, the second Philco in the house.

Some older people who retire early, and srill want ro listen to the radio before they go to sleep, may prefer a larger, more jxnvcrfiil radio than others for whom die distance range and volume of one of the Philco com pact: models is quire sulliciem:. But, leaving questions of personal prefer ence aside, one t hing is sure: the radio lias entered the bedroom todav and in many homes has become as much a fixture as the bed melt. The enjoyments to be had through radio reception are, of course, not restricted by any means to home owners and to people who live in apartment houses.

Styles of female dress have been brought about rhar are at once appropriate to the occasion, easy to ger around in, and good to cast the eye upon. The ladies have Jong since adopted as a mode comfort clothes that change radically with the season. They have furs and rich materials to keep out the chills of winter; clothes of lighter weight for fall and early spring, with auxiliary w raj's for the cooler davs; and in the summer, zephyr-like fab rics in dresses cut to permit the utmost in body freedom and comfort and to allow full exposure to the healthful, beauty-inducing rays of the sun. But man, taken by and large, still grumbles through the summer in clothes that have little relation to rhe requirements of rhe season. Many of diem actually wear suits built: to repel rhe icy blasts nf winter. They realize well enough that rhey are no: being comfortable, bur sometimes fail ro appreciate that they also are being grossly uneconomical. Heavy suits wear out quickly when damp ened by the excessive perspiration they induce when worn in remperarures to which they are ursxuited. Other men in sheer desperation stalk into a haberdashery and buy a sjmmery-looking scut even though, they know it is impractical for every day use. They may be somewhat sell conscious in wearing it at the office, hut they accept rhar situation as the lesser of two evils. They prefer a garmenr that is cool, regardless or t:ie fact that a sweltering session at the desk probably will leave them looking like last week's wash. If man has ingenuity enough to produce satisfactory garments for women, why does he not invent a material which can he made up into suits that arc smart yet dignified, com fortable cut and cool, yet really practical to wear? The answer is that he has. That's rhe la rest news in the men's wear industry. One of the leading designers and manufacturers of garment materials in this country is rhe Farr Alpaca Company of Holyoke, Massachusetts, This company has spent a great deal of time studying men's likes and dis likes in summer wear. As might be ex peered, it was found rhar rh ere is a dearth of really satisfactory fabrics. The expense of keeping rhe conven tional type of garment in a fresh condition also has been an important factor in preventing rhe more wide- Page Twelve A the DU PONT Magazine spread adoption of light-weight suitings. For years the Farr A l paca Com pan}' has specialised in the development of men's wear summer suitings, and has therefore experimented with various materials and combinations in an effort to produce a suiting that would satisfy all of a man's requirements. As a result of recent research, Farr has developed a new line of fabrics that is introduced under the name "Farr-East Summer Suitings." These fabrics are made of Du Pont Spun Rayon and silk and produced in different weights and in both plain and novel weaves. They are offered in fresh, light colors and in textures that arc really cool and comfortable. This material has been found to hold its pi css cxiicmely well, and ir is so durable that it can he washed re peatedly without injury. Men's suits made of " Farr-least" fabrics are distinctly summer gar ments. The content of Du Pont Spun Kayon gives the cloth a coolness that is noticeable even in rouching it. Due ro the myou-siIk mixture, these suit ings have an unusual softness of texrure,yer the material is as firm as those made of worsteds and wools. As a result of these luxurious proper ties, suits made from the new fabric are admirably adapted Jo both busi ness ane social wear.

Mud} might he written on that subject, but for rhe present, let us consider briefly how "Pyralm" sheeting is combined with doth for certain purposes. For yesrs du Pont deanuMe collars have been produced end sold through regular rerail channels in flits coun try. The procedure ot making them is first to laminate a piece of fabric between two sheets of the plastic, making a three-ply sheet with a fabric center. Then a linen finish is applied on the surface hv placing a piece of re.il linen between two of the lami nated sheets and applying heat and pressure. When the linen is removed, an exact reproduction of its texture is left on the surface of the pyroxylin. The stock is then cut to size and made in to rhe finished product. These col lars have the appearance of real linen ami are very durable, non-wiltmg and can be icadi y cleaned with a damp clot.Ii. Next, consider some accessories of interest to women, handbags, for example. Not so Jong ago merchants became aware that manufacturers were developing some very attractive bags by using "Pyralin'' laminated to a coiron fabric; that the cloth material was well suited for making bags rhat were of a practical, durable, good-looking and, must important, salable kind. A few months ago a few of these handbags appeared in a well-known department store in New York Can. Stylishly designed, made of this lami na ted material in beautiful shades of white, brown, blue and black, these bags immediately became popular. Sales Jerks had ironhlc keeping their counters stocked. More were pur chased, and women bought them as fast as they were shown. Other stores rushed orders to the manufacturers, and ai this writing, a vogue for these handbags has swept the country. Almost every department store, lug gage and gift shop now carries an extensive assortment in various colors and styles. The application of cotton fabric to pyroxylin plastic is a very simple process. After an unpolished shea of "Pyralin" is srraightcnccl, it is given a coaling oi cement on the side m which the fabric is to be applied. Incidentally, rhis cement, a standard solution, is the same as that used in joining together two picas of the plastic, and after a sheer is coated with it: and allowed to dry for about fifteen to twenty minutes, the surface becomes "tacky.' The fabric is then placed on the coaled side and care fully smoothed with the hands Co eliminate aiiv wrinkles that may be present. The composited sheet is then passed through a pair of rolls which insures rhe complete removal of all uneven areas. Permanent adhesion of the fabric to the plastic is secured by placing the sheet between finishing plates in a press-polish machine and subjecting it to both heat and pres sure, and then the usual polish is applied to the surface. In the finishing operation, while the composited shea, is still in the press-polish .machine, ir is possible to vary the depth of penetration of the coUoa fabric into the sheeting mate rial. If it is desired that the finished srock shall show the effect of a fabric in relief, a piece of the clotJi h placed over tlie cotton instead of a smooth finishing plate. If it is desired to embed the fabric into the sheet, stock, a smooth finishing plate is placed next to the doth and more hear is appl led in the press polishing opera- This handbas Is made of black "Pyrafin" laminated fo doth.

Por some purposes it is desirable that a certain amount: of seasoning be given to the cloth-hacked pyroxylin sheet in order to remove the solvents us the cementing solution. So the sheers arc hong for a few days in heated seasoning vaults, hut this is non always essential and depends upon the eustomerC requirements. Shoe manufacturers soon realised the possibilities of this treatment of ' Pyralin," with the result that unlay many of the fabric shoes have "Pyralin"-covcred heels in some fabric finish such as moire, linen, satin and the like. In fact, any cloth, texture may he transferred ro the sheeting material and used as a covering for vvood heels, taking the place of the netted fa fit its. The problem is merely one of embedding the fabric design info the pyroxylin, and when the fabric is pulled oti, the design is left: permanently on the surface. The outstanding properties oi a "Feral in '-covered heel arc, of course, .its durability and the fact that it docs nor show scud marks. Women's shoe heels are subjected to rough wear ( ontiiiuallv. To mention olfue chairs, brake and clutch pedals of automo biles, curbstones, subway grates and rhe mis-steps of partner* on the dance floor is to suggest some of the acci dents that may easily leave ordinary shoe heels had!v m. sided and mailed.

The faci that ir is siructurallv strong and that it is impermeable to gases to a remark able dcg:ee appear to recommend the material, but it ts still in the experi mental stages, Fabric material is also being lami nated to ''Pyralin" by various manu facturers and then applied djreu'ty ro wood. This is done primarily to secure more perfect adhesion.

Otilv a Jitrfe more than a century age the first enterprise of this kind was started m the United States. Only sixty-five years ago the first transcontinental line was com pieced at Promontory Point, Utah, with rlic driving of a golden spike. Engraved on otic side at this spike were rlie.se words; ` May God con tinue the unity ol our country as this railroad unites the two great oceans of the world." That prater has been answered, for since 169 rail lines have been projected to every State in the Union, a vast network that represents osic-third of the world's total railway mileage. We are all heiiehciarics of the ser vice rendered by this great transpor tation system that has made possible a nation-wide development of trade, commerce and industry; for the rail roads opened the way to resources that oiTcrwisc would not have been touched, perhaps, for centuries. In rhe early days, physical obstruc tions were the chief problems the railroad companies laced. Today, i r is the competition ul newer transport agencies and other diikculfics thar give concent. Bui with streamlined trains and other improvements in rail transport facilities for fast, safe, de pendable and economical service, the industry may he expected to function importantly for generations to come. The du Pont Company has long supplied the railroad industry with essential materials to clear rights of way, to drive tunnels through moun tains and under rivers and to advance rail lines through rocky hillsides. It must be remembered, too, that explo sives also serve in mining coal and iron and other metallic ores; in quar rying rock for roadbed ballasr; in constructing dams for hydroelectric power development. They are indis pensable materials to the railroad industry in many ways. For equipment, operating and main tenance needs, the railroads also re quire a great many other du Pont products, such as coated fabrics, fin ishing materials of various kinds, refrigerams for air conditioning uses and a variety of chemicals. The cover illustration is, therefore, a respectful salute to a great key industry' which has been a valued customer of the du Pont Company .sijK.e the first railroad was LuiiJr. Protect the Children Wit h in the next few weeks children throughout the country will again he placing in lots and open fields.

The low trap is atronged so that it may be turned halt way around and used for trapshooting Skeet Challenges the Shotgun Shooter This year-round sport has quickly gained nation-wide popularity. A few notes here for beginners who are taking up the game Sk e h t lias been called "a highly exasperating form of clay-bird shoot ing," nevertheless, it has a compel" hng fascination for the ever-growing number of its devotees. It is not an easy game to master, but ir has a "come-on" rhat keeps the would-be expert hopefully plugging away imril he can score a ``rwcntv" or "twentyone.*' And then, perhaps, at the next shoot he has a "sinking spell" and breaks only '`seventeen," which so hurts his pride that lie starts anew to practice with a high resolve to get this game "down" for good. As in go!f, so in Skeef, par scores reward only those with more than average skill. It is the zest of struggle to attain perfection that keeps all sports alive. Less than a decade ago Sheet was a new sport. In 1926, W. H. Poster, editor of The N^t/rmal Sfwrfm/an, and the lateC. E. Davis, both of Andover, Massachusetts, undertook to provide a pleasing and informal variety of practice for field shooting by means of clay targets and traps. They invented this new game without real izing rim ir was destined ro gain nation-wide popularity in a surpris ingly short time. Born in the Bay State, this game was christened "Sheet" by Mrs. Gertrude Hurlbutt, of Dayton, Montana. She thought: this old Scan dinavian form of the word shoot would be apt, and Messrs. Foster and Davis though!: so too. At Ballard Vale, Massachusetts, they set up two traps, one to throw targets from a high point and the other tosrart them flvingfrom a posi tion near the ground. They drove stakes to mark stations from which the shooters would aim at the elusive clavs from a variety of angles, and when all was ready friends were in Page Seventeen vited to try this new game. We are told that there was much talking and joking between shots and main a "bird1' got away imrouched, hut shooting in this manner proved to be real sport and a general good rime was enjoved by all. From this simple start, Sheet has grown steadily in favor among sports men. Today, there arc more than SIX! Skeet clubs scattered throughout the LI ni red Stales and several foreign coun tries. Leagues and state associations have been organized. Championship tournaments are held regular!v, with shooters manifesting the same inter est in hreakingSkeer targets that they have all along shown in the older sport of trapshooting. Of course, de velopments and refinements have been added since Messrs. Foster and Davis invented the game. Ic still aflurds excellent practice for fie hi shooting. The DU FONT Aldzajine hur nowadays men and women who never hunt live birds, find Skeet cruirelv sufficient unto itself. It is not our ['-urpose here ro go into the derails of field Javout, equipment, rales, guns, loads and the like. Previ ously, in i his magazine, die reader has learned rhar a round of Sheer calls lor a aeries of twenty five shoes....two targets from cadi of the eight* srarions, rc "resellrw/r incoming and out going "birds": four pairs of doubles, that is, two carpets thrown simul taneously, ro be shot at from stations J . 2, 6 did 7, and iic optional target, the rwencv-iifrh, which the shooter mav call for ar any station he may choose. Assuming that the ambitions begin ner already knows what is required, the question of shooting Technique arises. How may one learn to excel ac this sport ? What are the fLinda-ircntai facts to hear in mind? Promi nent Skeet shooters and other dose students of the game are able to give the tyro some useful pointers, and we shall hope to render a service by quot ing excerpts from Skeet Shunting 1 Sinta and The du Pont Sheer Handbook as iollows; Frank G. Treager, Jr., of Rosebud, New Jersey, is the 1933 champion of that state, having broken lOOsrraightx He was also high gun at the Tri-Stare Shoot, where he broke 99 x 1(X) in compciicion with the exjert shooters from Pennsylvania, Delaware and New Jersey last year. Mr. Treager has this to say about the shooter's stance: 4 `Tlu shotting pevs irion is the camt a* the held powdun when expecting lodi sh .t bud; /ml is, the gun / ;,dd down and somewhat forward h the position ot 'ruikh,' and the target is (did for, 'Ho pun is t.irvHvji ta the shoulder u her the target i-- seen in tin. n;r. ami mu helure.

In the opinion of Russell W. lilliotr, of Kansas City, Missouri, who is a nationally known shotgun expert and the author of "Vision in Shooting," the correct answer depends upon indi vidual characteristics of vision. We gather that if a shooter cannor see equally well with both eyes, that fact lias its hearing not only upon the iminedi;ite question, but it also deter mines whether it is herfer for him ro shoot from the right shoulder or not. If his left, eye is stronger, he should shoot from that side, and vice versa. In general, Mr. Fllioct notes: ~Tr bus oar been my experience thus both eves being open is a material asset in single tagger shooting, as There is plenty ot time for tne one-toed '.hooter to t mc L up the career and h-cak -t before ic is out oi range.

Women who are taking up this sport will do well to accept the following hints from Mrs. A. M. Vance, of Wahan, Massachusetts, who is a par ticularly vx ell-qua liked mentor. She won t he Great Eastern States' Ladies' Championship at Lordship, in 1933, by breaking 90 x 100. Frank G. Trouser, Jr., of Rosehnd, New Jersey, was the state champion Sheet shooter in 1933, as wolf as high gun in the Tri-State Shoot. Ho Is defending hk laurels in the 1934 State Championship Event as this issue goes to press She says the secret of good Skeer sco res is " ahsul u re con cent ra t i on, ' ' and she has developed that faculty throughascries of'*reminders'` which she men rally repeats to herself just before each shot. For example, to quote: "At the ^ ra Firms from three ro six indu/ve . . . I fh nk `shonr ahead ;mJ under/ having in mind s ddmitc picture ot the shot its success!nilv executed ar that parik.nlar Mauon in the past. This picture, which consists chkdh of rhe gun muzzle in rckukm to the target, must he couHired up with phurographk dariry in spire nl all dissraalons and held paramount in mind during the inter val between the call fur the target and its appearance." Ar Station No. 8, wirh its two in coming shots, she thinks, " Be quick!' ` during the same period. When shooting at doubles, she endeavors to shut out of her mind the fact that two targets will appear in the air. She concentrates entirely on rhe first one to be shot at, anJ, when it is broken, makes a quick recovery and breaks the second. The prowess of women on the Skeet field and their possibilities of qualify ing as experts are suggested in a few lines by Gertrude L, Travis, editor of the Women's Department of Skeet Shutting as follows: Mrs, Anna Mary Vance, of Waban, Massachusetts, takes aim at a /tying Skeet target, and with usually Satisfactory results.

And almost any housewife can tell you how pitifully soon her airtains and linens become soiled at an open window. Consider the effect of this on the thousands of soil able articles found in department stores, and yon can begin to realise what die cellulose film, `'Cellophane/' is doing to keep merchandise clean fur the consumer's use. For in many stores, sheets, pillow cases, blankets, lamp shades, lunch eon sets, hosiery, stationery, towels, boudoir-chair covers, notions and many other items arc being sold in 4 Cellophane''-wrapped packages. Another benefit to the customer, in addition to more sanitary merchan dise, is freedom from defects due to any excessive handling die product may receive. The appearance of the package* itself is also enhanced hv this wrapping material, and in many cases, items so packaged actually become suitable for gift purposes. And all this is accomplished without destroying the invaluable right of the customer to see what she buys! A point often overlooked is the fact that `'Cellophane" transparent wrapping saves the consumer the cost of any initial laundering of such articles as shirts, infants' wear, towels, sheets and pillow cases. For a sheet the saving might be ten or twelve cents, and for a shirt, the saving would run even higher- - any Page Twenty where from fifteen to twenty-live cents. Otherwise, the cost of the Jirst laundering would have to he added to the purchase price. The next time you are in a depart ment store, take notice of the increas ing number of articles which are being sold in "Cellophane"--wrapped packages. The cxecu Live staffs of these organizations are constantly seeking to find ways of improving their operatingmethods, with the ultimate objective of giving better service ro customers. That ''Cellophane" has also made the selling problem easier is obvious, hut the greatest satisfac tion to the proprietors of these large rerail establishments comes from the knowledge that this product permits them to supply merchandise which is not only sanitary but also immaculate enough to satisfy the most fastidious store patrons. Towels wrapped In "Cellophane" mean complete visibility and freedom from dust, dirt and pulhd threads The DU PONT Mtgazsne Some Questions and Answers That you may have a better understanding about exp!osive$/ blasting accessories and howto use them Q. W1i;ir arc the different types of dynamite (or agricultural work? A. Extra ' Ammonia) Dynamite is the most common dynamite for agri cultural use. The dynamites in this classification are made in strengths from hfrt.cn percent to sixty per cent. Nitroglycerin dvnamiies, which con tain nitroglycerin as die only explo sive ingicdienr, arc also iinporranr. They should comain die actual amount of commercial nirroghccrin designed as their percentage strength. For example, a forty per cent nitro glycerin dynamite should actually contain forte per cent nitroglycerin hy weight. Bui Icy ( h igh cartridge coum) dynamites, which comain ammonium nitrate as the principal explosive ingredient, arc other impor tant types. Q. Where should explosives he stored ? A. Explosives should he stored in a dry, ventilated building ass ay from dwdlings. Thev should he* stored in the original unopened cases or with the cover nailed on. The cases should he oh' the ground and placed where children, irresponsible persons or ani mals cannot get at them. Fire is the greatest hazard in connection with explosives so srored. Therefore, the explosives should nor he stored hi shops where a forge or other sources of lire mav he present. Grass and other iiillammable materials should he cleared away irom buildings for a distance of twenty-live fecr. Blasting Caps should he stored in a separate building from high explosives, and both should he Maced under lock and key. Q- Whar h meant hv the term `low freezing '*? A.

When j''timing in the end, the paper should he folded hack at one end of the cartridge, and a hole made with a wooden punch about the size of a lead pencil into the exposed dynamite, into which the blasting cap, crimped on the freshly cut end of a piece of fuse, is placed and tied. Q. What is a blasting cap? A. A blasting cap consists of a copper capsule loaded with an initial priming substance. The load is care fully measured and is then pressed Pag r Twp.nty-One sccmcly into the capsule, so that ordinary handling or jarring received i u shipment will not loosen rhccharge. 1 here are two standard sizes of blast ing caps...No. 6 and No. H. Q. Whar is an electric blasting cap? A. An electric blasting cap consists of a cop|x-t capsule loaded with an initial priming substance, sea leal with sulphur and waterproofing, and if: is ignited hv a very line resistance wire which is heated by an electric current. Electric Masting caps are also made in two strengths No. 6 and No. 8. They should he detonated hy means of a blasting itiaehinc. Q. What is safetv fuse? A. Safety fuse is used to fire blast ing caps, which in turn detonate dvnamitc. It consists of a small center thread surrounded by a small train or core of black powder, the whole os which is wrapped in a covering of paper, jure, thread, asphalt and o:he: waterproofing materials. It is so made that the powder burns at a uniform speed through this train, with an allowable variarion of ten per cent either wav. Q. What is the proper way to I ight fuse ? A. Lighting a fuse is a verv simple operation. Bciore lighting, the fuse should he slit with a. knife so as to expose the fresh powder. When a safety match, is used, the head is placed in the split end of the fuse directly in contact with (he powder.

At first glance the solution of this problem would appear to he reason ably simple, and amateur attempts were made by certain enthusiasts, who cut off the nose of the bullet. Such crude attempts, of course, were not conducive to good target accuracy, hut they illustrated the principle desired. This practice, fur thermore, reduced tlie weight ol the bullet and consequently increased the muzzle velocity.

By utilizing the brass shell ortgi nated by the Remington Arms Com pany, Inc., in conjunction with our CIKleanbore" prifiling mixture and special powder supplied for "JHi Speed" cartridges, it was possible to establish a muzzle velocity with the proposed sharp .shoulder bullet ol 1 .300 feet per second.

The trained agricultural blaster can make a narrow, deep ditch or a shal low, wide one. By the propagation method, any length of ditch can be blown almost in the twinkling of an eye. No longer is it necessary* to dear the right of way ol stumps and boul ders before making a ditch. Modem methods make it possible to do the entire johwirh a single blast. Where a ditch up- to thirty feci in width, with a deotfi ol five to nvelve feet, is required, rhe procedure is to space the holes five or six feet apart in a singe row on rhe center line. The holes are made live to cighi feet deep, and the loading varies from twenty to hhy sticks of ditching dynamite to a hole. In order to accommodate the load, the holes aie first sprung by exploding a small charge at the bottom, thus making a chamber to receive the working loud. By the propagation method, which can be used only in wer soils, the explosion of one charge sets off all the others in the row, lor the water in the soil carries the so-called wave Pti'Ji' Twenty-Thr^v of detonation from one hole to the next one in very rapid succession. Wide, s tallow ditches of three to livc-ioot depth and ranging up to thirty leer or more in width can he blasted bv shooting a single row of holes oil each side, and rien blasting the center section. This is known as the relid raid spreading met hod. The depth and spacing of the holes, and the amount of dynamite loaded in each one, all depend upon a number of variable faelors. But the point of interest is that broad, shallow ditches can now be made with explosives.

What arc blasting machines? ,4. Blasting machines are porta hie electric generators which operate by rotating an armature by rlie down ward thrust of a rack bar. Thev are designed for firing deerne blasting caps connected hi series only and, therefore, thev deliver a fairly low current or amperage. When nor in use, blasting machines should he stored in a dry place. Q. What is the cause of misfires? A. Misfires usually result from full tv practices in storing and han dling materials, or in lighting fuse. The chief source of misfires is the improper use of fuse. A. misfire occurs in blasting when a iUse docs not burn through and lire the blasting cap, or when a bias ring cap or an electric blasting cap fails to fire the charge. Q. When should a misfire be investigated? Page h/enty-Four A. Misfires occurring when firing with fuse are dangerous. If a charge fails to lire when primed wirh cap anil fuse, the safe practice is to let the charge stand for twenty-four hours before investigating the cause for failure, or replacing the charge. In the case of electric blasting, if the charge fails to explode when the blasting machine is operated, rhe ma chine or source of electric current should he disconnected and after a delay of thirty minutes, the enrire operation may be safely checked.

Re mo v e air from the world, and all living things -- humans, animals and plants --must perish. Is it not strange that scientists should search unceas ingly for better ways to remove air, to shut off air, from many of the things man makes? Yet it is so. For air, while sustaining life, promotes nature's process of oxidation, and moves swiftly to consume your property. Combined with moisture, it starts rust and corrosion which eat into structural steel, ships, trains, and tractors. For centuries man has tried to halt the inroads of oxida tion, to reduce the colossal waste of corrosion. Chemists in the du Pont laboratories have achieved re markable results. From these laboratories has come an out standing finish for protecting industrial machinery. It is Dulux Industrial Finish. It is made to resist corrosion ... to withstand the effects of heat and oil . .. to give longerlasting protection. This is but one definite example of du Pont service to industry. In the last ten years, du Pont chemists, seeking finishing materials of greater service value, have been re sponsible for many of the major developments in finishes. To the automobile industry they gave Duco, and Dulux. To textile mills, food plants and others, they gave Dulux Mill White--to the marine industry. Dulux Marine Finishes. In addition, there is Brush Duco for furniture and wood work in the home, Dulux for refrigerators, and du Pont paints and varnishes to beautify and protect the home.
