DYNAMITE Aids in the Construction of THE EMPIRE STATE BUILDING TOWKIilNG 1245 feet above ihe "side walks of New York," the Empire State Building looks down upon (he neighboring skyscrapers! It is I he newest engineering marvel--a tribute to architects and artisans -- but dependent upon a mighty ally--Dynamite! W orking efficiently* quickly and econom ically, du Pont Dynamite blasted the solid rock, and so aided in the construction of the foundations of this eighty-five-story structure. Du Pont Explosives arc the mighty allies of industries--mining, quarrying, contract ing and agriculture. All these owe (heir progress, in a large sense, to the forceful efficiency of high explosives. To provide industry with the most efiectivc types of explosives, lo produce in adequate quantities, and lo render a practical service lo the users of du Pont Explosives are the purposes of their makers. Whatever may lie your requirement for explosives, there is one made by duPont which provides the maximum of efficiency.

Fin ished products arc tested for quality and uniformity in the laboratory, and for durability by long exposures at the proving grounds called "paint farms." All of which means that production standards have attained a higher level. To modern cheiimry goes r lie credit for developing Duco, which marked the greatest forward step in the man ufacture of protective coating for generations past. This finish grew out of thenecdsof the automobile industry for reafIv serviceable: products. Because Duco was so durable, many people ac first thought that aufomo bile reumslting shops evere doomed.

T. RLl.iS Hfmii: optical goods merchant, besides keeping tip with business conditions, roust follow closely the fashions of the hour. For fust as stvle trends ui wearing apparel and other personal articles are continue llv changing, similar influences opt rate to change the shapes and designs of even hiss frames. Fashions arc notoriously short lived. One can ne\er be sure that a style in vogue will long retain its popularity. Vet dear vision is so essential uni so necessary in most cases that people want these a icessones ro be exactly right optically and no less correct .is to stele. People once thought glasses were of necessity disfiguring. Thai opinion mar have wen justified rears ago, hut not rodav. for optical frames may he ol>r;tinci! and fitted to suit the par ticular rccjiiirementsof anv ind ivsdual. Nowadays, with a great van cry of styles, designs .md models a variable, it is ease to select glasses that are becoming as well us practical. Indeed, we are told that some jxi'opfe wear glasses nor so much f rom necessity as from choice, as a menus of improving their personal appearance. What has brought about: this change** Mam dungs, bur certainly the adoption and use of Fvruliii by die opricul industrv have been and continue to he potent si vie influen-ces. One liiiporiam requisite of eveglasses is dial then shad he comfort able:, pardi ul.ir!v around the nose, curs and temples. Pyrulin Irames are made to meet that demand fully. Moreover, those who wear non metadie frames never have cause to fear slam irritations or infectious resulting from their use. Again, rhese frames give needed protection to costly lenses. People who wear rimless glasses know what happens when their spectacles fall to die floor. Too often it means a cracked or broken lens. When Pyraiin-rimnieJ glasses figure in such accidents, the lens breakage hazard is negligible, for the semi-flexible frame absorbs the shock of the fall. I his economy oi upkeep is a point of real advantage, and if suggests another cquafh noteworthy. The low cost of Pvraliu, compared to that of natural materials such as genuine shell, enables manufacturers to pro duce and sell optical frames at very reasonable prices. Most important from the viewpoint of style is the v.irierv of colors and color combinations available to manulaeturers of eyeglass frames. The use of Pvraliti in pearl dice is combined with plain colors aiiords a suiheient range of materials to produce suitable stvies for all classes of people and torall occasions. Businessmen, laborers, children, debutant o, sportsmen -- these ane mane others had F'yraliji frames suitable at all times. While it is futile to say what the color \ agues or sc vies mnv he in the future, one thing is c.-rr.i in : However drastic any change may be, optical manufacturers who use Pvraihi will nc able to meet Fashion's require ments as and when they appear. Today's styles are featured in some informative book lets published by leading optical concerns that man ufacture Pvralin frames.

A hv speak of over-emphasis on football, when the major folly is due to under-emphasis on the importance of textbooks in the educational scheme ? Without good honks ami good teachers, any public ha!! of learning is a false front. It may be outstanding in its imposing architec ture, but that means little unless the equipment anti facilities for educa tional work arc of an equally high stand ard. F.Jucators will tell y o u tli.it there has been more complaint about the cost of textbooks in public schools t(ian id] other items combined, The usual line of reasoning runs something like this- "Ladies and gentlemen of the school hoards, hv cutting out thc hisrory of Kngksh literature and making chat outside reading, by eliminating the supplementary text, Blank's book on physics, we can succ our tax pa vers one mill on the dollar ilus year."

It is less Jtkdy to pick up dire and soil than the average distil-covered hook, and for rhis reason it is much safer in the hands of the pupil. It saves the expense and the annoyance of covering the dieaoly-hound hook wich a paper jacket, which quicklv becomes soiled, and, moreover,causes a great deal of confusion because the jacket hides the tirle of. the book. And this problem of soiled school hooks is something that must come under the public spotlight soon, 1 .egislution has abolished the public drink iug cup and the roller towel, be cause of well known health hazards. hut as vet it has overlooked entire!y the unsanitary school hook which is a potential carrier of infectious dis eases.

After rhat it explodes too quickly, wasting its force in high-vc-1 oeit}" wanes which strike against the evlsncfer walls and cause that metallic sound associated with "knocking." The next step was to find some thing which would control the com bustion <>1 gasoline so thar higher coin pressu ms would be praci icable. Thomas Midglc) ,Jr., ami T. A. Bend, of General Motors Research Corpora tion* undertook that cask. They first discovered that gasoline ---even eemsene could be rendered knock less by the addition of Lcr- tain ingredients. The first such ingre dient they found was iodine. Bur ro he coinmcrcia M v practicable, an "ami-knock'` ingredient must Mag i. Lig h t <7/fe DU PONT^<7z j >w prove itself harmless to motor*.

In that timeill ore than $3,00o dilfcrent chemical combinations were tested in and lor their edecis on gasoline engines. And in i yxz there was finally hum Edn 1 ihnd, the basis of Eth}'I gasoline. So Important die the scientific world regard this discovery that its 1914 die American Chemical Society awarded Mr. iMidgley the Nichols Med a L If yon could peep into the cylinders ol your automobile and watch what goes un Liere, vou would see one of the mi/St interesting sights of the world. Engineers, with the aid oi special instruments, have been able to Jo just that. Let us look inside a cylinder through the eyes of an engineer. Ordinary gasoline is m the cylinder. The valves snap shat, and the rising piston com presses the charge into a fraction of the space. The spark plug throws a tinv streak oi lightning, and tile coinpressed gc so line vapor is sec ablaae. Pressure inside the cylinder shoors up again....two, rhree, four times1-- be yond the limit the gasoline will stand. What is still unhurried is wasted in a furious, white-hot explosion that is known as `'detonation" or, more popularly, "knocking/' Now look again. This time Ethvl gasoline is in the cylinder. The vapor starts biasing as quickiv as before, but at the point where the ordinary gasoline exploded, the pressure con tinues to increase smoothly, pressing the piston down with a gathering force that delivers more power to the crankshaft and to the rear wheels. The Ethvl fluid in this gasoline lias or,nro!!t:! c;wku.<tb`n and checked the wasteful ' knock," That is whv Ethvl makes ./vy car run better and is necessary to the new higher compression cars. Since Ethyl was discovered, great strides have been made in the develop ment ol automobile engines, partic ularly during the past few ve.irs. In 191s, the average engine developed less than six tv horsepower. Today, the displacement of rhe average engine is not great! v dilrercnt from thcdisplacentac of iy15, but it develops mure than niucl) horsepower. Each e 11 hit inch of combustion space therefore delivers more work to trie crankshaft. The fact that the average coni pres sion ratio id automobile engines lias been increased from somewhat less tlianq.s ti> ; m 1925 to approximately 5.25 to 1 today is largclv responsible for rhe present excellent all-round perionnanee ol motor cars* What might he expected in the future is illustrated in a avoir tesr. One automobile with a compression ratio of 5.2.5 to 1 took iH seconds to a cede rate from 5 to 45 miles per hour. An identical automobile with the same engine but 7 to 1 compression ratio took 14 seconds to accelerate from 5 to 45 miles per hour. The wide distribution ol Ethel gasoline has made available a fuel oi sefucicnr anti-knock value to de velop the best perionnanee of the most nuxiern high compression engines. M;m\' automobile manufacturers now offer standard or optional high com pression engines requiring a fuel of Ethyl standard. The Ethyl Gasoline Corporation maintains tesr 1 n g 1 a bora torses throughout the cotuirry. Samples oi every batch of gasoline to which oil reinicr.s wish to add Ethvl hold .must he sent to one of these test ing laboratories. There the gas oline must pass tests for distillation characteristics, corrosion and g uni forming tendencies, sulphur concern and anti-knock value. The samples must he found sans factory in each and all of these respects bdoic the refiner blends his gasoline with Ethvl lluid to form Ethel gas olinc. After the blending, samples of die resulting Jith\ 1 gasoline arc sub mitted ro the laboratories for a ana! cheek before it is released lor sale. A large stall of held representatives of the Ethyl Gasoline Corporation is constantly active throughout the country, purchasing samples of Ethyl gasoline from pumps at (illmg sta tions, so that additional tests nut) be made ro protect the qualify ol the Ethyl gasoline going to die public. In 1921 it was a big day tor the Ethvl Gasolmc Corporation when six quart cans of lithe 1 him! were shipped atone time. A quart of Ethvl fluid is sufficient to mix about 20c gallons of gasoline. Today, a licet of tank cars is required for shipping pur poses. One tank car contains enough of it to mix approximate!)- 8,000,00c gn lions of g.isnhne. There are now 07 oil refining com panies licensed to sell Ethyl gasoline. Til esc constitute almost ever)- ilia jor oil company in America.

While there is plenty of ityu....ul :i kind the sorry fact is L.hitc i: is nut ayn g/mx New York's problem contemplates the distant future, looks ahead to a time when almost literally there may be 'water, water everywhere, but not a drop to drink." bather Knickerbocker has been on guard against that possibility lor years by carrying throng!) plans to provide an adequate water supply well in advance of current needs. But tlie problem of kecoing up with a growing city's thirst is no small one, particularly when that city happens to he the most populous of any m the western hemisphere. Prior to 1917, New York obtained its water supply from the drainage area of the Croton River and from wells in Nassau County and in the horough of Brooklyn, hi ihat year Catskili mountain water became available. In 1 916 additional supplies from the water sheds of Schoharie and Jfsopus creeks were impounded in the Schoharie and Ashokun reservoirs, the chief collecting centers for the Caisktll svsrem. Space forbids a de scription of the cm ire system, hut as an approach to an ini pun ant city project now under wav, suppose we trace briclly the water!low from the mountains to Manhattan, more than 1 <50 miles away. First, visualize a zo-hillion gallon reservoir -the Schoharie with its impounded waters racing southward chrough the 18 mile Shandaken Tun nel that empties its cargo inro Itsopus Creek. Fifteen miles farther down is ilic Ashokau Reservoir which holds 12.8 hiJ lion g.i I Ions and is the northern terminus of the Catskill aqueduct. Tim great conduit, ninety-two miles ong, has a capacity of 600 million gallons of water daily. It extends down the west side of 1 he Hudson, dips under the river near West Point and continues on to the xp-hillion gallon Kcnsico Reservoir in West chester County, and thence to the Hill View Reservoir at Yorkers, just north of the New York City line. This storage ha sin on high ground has a capacity of 900 million gallons and from it distribution is now made into the live boroughs by means ol a pressure tunnel, which is also con nected by pipe lines I catling rn Silver Lake, the 435 million gallon terminal reservoir cm Staten Island. This sketchy outline does nor Jo justice to the magnitude of the CatskilJ system on which has been expended to August j , 1919, the sum of $190,000,000. But nt least it fur nishes a background for the work now in progress which will great!v extend arid enlarge die water distri bution facilities in New York Cnv. The cost of the portions of the Catskill aqueduct within municipal limits, including City Tumid No. y pipe lines, appurtenances and die Silver Lake Reservoir, represents an expenditure of about $37,000,000. City Tunnel No. x, now under con struction, will cost approximatdv $43,000,000.

P. PAR SOYS Ncn many years ago one way to dist over the complete range of almost anv man's vocabulary was to get sonic member of his family to suggest on a Saturday afternoon or a hoi id ay, `Matt's polish the bits." The various polishes then available depended so largely on "elbow grease" for success that it was indeed an ordeal to use them. And even ifJohnnie, Alary and Mother herself said, "Well help,'' usually they soon wearied and it: remained fur Dad to do the entire job alone, or finish the hood and a fender or two and let the rest go as a had job. Then the lust Yo. - Duco Polish came along and Ilk* became decidedly more bearable, lids polish produced a superior luster with considerably less dTon: than was formerly required. But the elu Pont (.ompaitv wasn't satisfied. Chemists in the laboratory went ahead with research work. Extensive tests were carried on. M anv new formulas were tried out and finally the better product was deed oped. Yow du Pont has formally an nounced Speed Blend, the new, fa sti ve orbing No. 7 Duco Polish, width nukes it much easier to restore the beauty of your car--and you can smile while doing it. In fact*, it's hard to polish a car with Speed Blend and not smile; it docs the triek so well. Du Pont chemists tile same ones who discen erect Duco....developed th is new product: in flic first place tor use at auto polishing stations where sav ing nt time and labor, in addition to first-class results, are extremely important. Then packed it in gallon cans only and called it Speed Blend - No. 7 Duco Polish, because it cleaned and polished so quickly. Speed Blend made such a tremen dous hit with the trade that it was finally adopted as the standard Yu. 7 Duco Polish and is now available to the car owner as well. It is for use on Duco, lacquer, baked enamel, varnish and all auto mobile finishes. It gives excellent results on furniture finishes also, and on chromium. It is entirely safe to use mn on the finest radio cabinets. In the home, housewives find it particularly useful. They have dis covered it easily cakes off sticky ungcr-marks kiddies always leave on furniture, woodwork and various polished surfaces. Just rub a little of the liquid \ igorouslv over the sur face, let it dry and then wipe it oil with a clean, dry cloth. Tins removes fill dirt and grease, res to ring the orig inal color and luster of the finish. It leaves ;i dry, hard, brilliant polish that sheds dust. Speed Blend is particularly effec tive in removing traffic film, made up ol oily, sticky particles of dirt which arc constantly' settling on your car....in the city streets, on the coun try roads, and even in v:r own garage. These particles collect dust, ,tmf arc baked together bv the sun anil the heat into a hard, dull film which soap and water cannot remove. It dulls the color of the finish, hides its 1 lister and makes the whole car look old and shabby. Under the ugly, soap and waterresisting rraflic him, the Duco finish ol your car is as bright and smooth as when the car w as new. Speed Blend whisks off tfie (dm with amazing case,and the change from drabness to gleaming elegance is made with little cl fort. It indeed oilers speed and ease in bringing back that showroom finish to any car. There never vet was a polish that worked so fast, so safely, and with so little cl fort.

The most unpardonable thingabout accidents resulting from slipping rugs is that they can be so easily prevented, because of the construc tion of the majority of mgs then; is bur little frictional resistance between their underpart and the iloor.

Presuming y;it svc; c I'ni'if runted wrrl'j these rigid sprcihcanons, just how would you accomplish the ruskd It so happens that this problem in some form has faced the dyers and weavers of textile fibers ever since the lirsc fabric was woven. The dye ing of extreme I e lung Yarns, sin'll as are necessary for the warps and fill ings of modern textiles, presents a peal rna o technical problems that are exceedingly tlslikull to solve. Pa g e Tw e n t y One of file most successful pieces of equipment: developed to date for this purpose is known as the Franklin Process package dyeing machine. Ac its best it allows a yam dver to comply with all die restrictions set forth earlier, producing any desired shade of any degree of fastness perfectly uniform throughout. 1 he secret oJ the success of the brankltr; Process is to be found in the core of the spool on which the yarn is wound before being [dated in the d) ei ig cylinder. This c o ik s Ls c k of a. flat, .spiral spring covered with a strong cotton tubing on which the uiidyed varn is wound, 'flic larger sizes of these spring cores are six or nine i idles in length, and on them thousands of feet of warp or idling thread can he wound. These cores are hollow, so that when wound and ready to be dyed i hev ears be placed, end on end, over a feedpipe that is perforated with holes throughout its length. Through these holes the d v c solution is pumped oiit: through the varn. It is O'fie IDU PONIT^flagazino th is spiral spring core that equalizes the pressure throughout each cop, or wound core, and so prevents un even dycimj of the thread. 1 lie dyeing operation is easily accomplished hv pi inng tin one or more feedpipes the specified number of cops, which are then all forLed snug] V together hv top plates. The dveing vlinder $ nest closed and sea led at the top, after which the dsesmh is pumped Into h through die perforated feedpipes and so out between the windings of the spring core and through the cons. After a few minutes the flow of the dye solution through the yarn is reversed so that it is forced from the outside of the cops :md hack through them into the feedpipes. In this wav, with f requeue changes in the direction of [low, the wound cores holding these great lengths of thread a re evenly and quickly dyed. The Frank lin Process is therefore a compara tivcly simple hut ingenious process for yarn dyeing. As am he readily seen, the d ye - stulfs that are to he used in the Franklin machine nrasr comply with rigid specified!ions. They must he completely soluble; they must he absorbed uniformly by the varn; they cannot exhaust too rapidly and yet they must have a high degree of aihnitv for the liber. They must he fast. A great amount ufcostly research has been carried out by the du Pont Company st> that the Franklin Process Company and its licensees could he supplied with the best possible colors for this exacting job. m'u-.i ,d:-fit:hrnh t'J b-U-,%'n ;! ;.ro,iC.:d tv fa, /in-; />t th,' l n;nl. n; Mr..--'.,-:,: Iiy/i Dir, <;/::> h-orr.

This is essential when color fastness is an important consideration, for the fastest colors niiiv give cere imsatisfui tore results when improperly applied. but ' fast,'* as used in the textile irade today, has a very elastic mean ing, not necessarily because there is row Intent to deceive but because die definition has never been stand,irdviL-d.

Noah with all his animals, two and two, could not have mustered one-tenth the variety that is in any modern live and ten cent store. In most shops it is no job at all to spend .more chan von have. In the "live and ten" it is a physical impossibility. The human backbone would hardly stand up under the purchase of more than 2.0 worth of assorted merchandise, and the values are really surprising. The manufacturers that serve Uiesc stores are found everywhere, m every corner of the globe. The writer once stopped in a little town in the Penn- k v I v'utiia muim ruins and fan nil there a factory that made most of the wooden coat hangers tor the big chain stores.
