There are several miscella of 50 feet, ami the rooms are hut 30 feet wide, there are left neous sources of supply that help to increase solid masses of coal 20 feet wide between the rooms. These t he output, such as the waste coal in culm "pillars," so-called, are left standing to support the overlying banks and abandoned railroad fills, deposits on the banks of strata, and they represent about 40 nor cent of the original creeks, coal washed down in river courses, and considerable deposit. amounts obtained from stripping operations. When a coal seam or a part of it has been mined as already Before undertaking to describe methods of stripping, it is in described, then the pillars are either "skipped" or "rubbed" order to discuss briefly the formation of anthracite coal beds to obtain as much as possible of the total amount of coal. and the usual mining practices employed. Skipping moans taking a slice off the side of the pillar, which Visualize for a moment a layer cake. In its finished state increases the width of the room and correspondingly decreases it prosMHs a certain analogy to the geologic formation of a coal the width of the pillar. "Robbing" consists in starting at the field. The layers ol cake correspond to the deposits of rode, the icing to the veins or seams of coal. The rock layers vary in thickness from a few feet to 200 feet; and the coal layers from a few inches to 50 feet. The oven product is limited to the size of the baking pan, while a coal field may he many miles in length and breadth. In the anthracite field then; are 16 recognized seams or layers of coal, with the greatest, depth of the lowest seam from 2500 to 0000 feet below the surface. When coal deposits were first formed they were like the layers of a cake--practically horizontal, Hut as the earth's surface cooled, contraction An actual and idea! stripping- basin from which clay, rock and coal have been re moved to the depth indicated by the dotted line.

As the miner always has untouched pillars between himself and the gangway, robbing can be carried on with comparative safety. But in either skipping or robbing only a portion of the pillar coal can be recovered; the rest Is crashed is Intersected at various levels. As each seam of coal is reached, a gangway--like a subway tunnel, but of smaller dimensionsis started from the shaft. Each tunnel is about 7 foot high ami covered when the caving finally occurs. The percentage of coal originally in the ground that can eventually he recovered by mining varies greatly under different and 15 to 18 feet wideband is driven from the shaft to the conditions.

Not infrequently in areas of considerable size the top seam of coal is found so near the surface that there is no layer of rock above It, but only sand, earth or gravel. This blanket of alluvial earth varies in thickness from a few feet to 60 feet or more. Under these conditions the coal cannot be mined at all, or at lies! only a small percentage, became there Is no roof-rock to proven! (he earth, sand Of gravel from fulling in upon the miners.

Ideal results could be obtained by stripping or quarrying first the cover and then the coal, but such operations are confined between narrow limits owing to their cost. Prior to the world war some stripping contracts called for a price of 1.7 cents a yard for the removal of earth ami 35 cents a yard for rock. This permitted the coal operator under certain conditions to remove 6 cubic yards of earth and 3 cubic yards of rock U> each cubic yard of coal. One advantage of the stripping method is that practically 100 per cent of the coal can be recovered. Such coal, us already stated, is to be found in surface veins with little if any rook cover; in outcrop pillars and chain pillars, and in virgin or pillar coal whose thickness warrants the uncovering of an entire basin to a depth of 200 feet or more. Strippings arc essentially pit or quarry operations. They are conducted according to their size and local conditions by mechanical aids, which range from picks, shovels and wheelTM barrows to gigantic stem shovels, weighing 10 tons or more, such as were used in digging the Panama Canal. Aerial tram ways, supported by towers located on opposite sides of the pit, and hoisting cables afford a means of raising and of removing the material in skips or hoK.es, except -where large blocks of rock are hoisted by chains and cables directly. After the earth has been removed from thick or pitching veins, gangways are opened below from which at frequent intervals chutes are driven to the outcrop. The rock, loosened and broken by blasting, may now be drawn through the chutes into mine ears, hoisted up the slope and sent t o the spoil banks. This is known as the chute inethud. In the main it has been employed most successfully as an adjunct to the steamshovel method. In steam-shovel work on shallow surface veins and out crop strippings the earth and rock arc removed by the shovel dipper and loaded into sidedump cars of about 4 cubic yards capacity. Small locomo tives or "lokies" haul trips of 8 or 10 of these cars to the spoil bank, which is located as near to the work as possible. One trip loads while another is on the bank being emptied; the two, acting as shuttle trams, keep the shovel working almost without, interruption. In deep liasin strippings oi considerable size, where the vein to bo uncovered is usually 20 to 30 feet or more in thickness, thn*e or four shovels may operate at the same time. The earth cover m first removed, and unless it is of the nature of harclpan, explosives are seldom required. The most satisfactory working face for the shovel in earth is about 30 feet, in remov ing rock the working face is, as a rule, either 15 find; or 22 feet high. This assumes that the rock has been drilled previously and loosened or broken up by black powder or 40 per cent dynamite. When rock too large to go into the tlippv.r is encount ered, bloek-uoiing or mudcapping with dynamite k resorted to in order to reduce h to a more convenient size for handling. Only thick seams of coni admit of basin stripping to any depth, but the reward is the recovery of from f>0 to 60 per cent of coal left in pillars, coal that could not be taken out economi cally by underground mining. Such seam- are seldom found in the original or unminecJ state. They yielded the bulk of their treasures years ago, but enough coal was left to make it profit able to reclaim the rest in this later day. As the stripping deepens the shovels approach the vein, crossing and reerossing pillars and empty breasts as the work progresses. Great care is exercised both on the mdcrup and in the basin, especially when near the vein, in order to prevent the heavy shovels from breaking through the thin crust o1 rock or coal on which they eland. Fortunately, such accidents rarely occur, hut more than one shovel has met this fate in the past. Basin strippings soon reach a depth from which the dump cam can not be hauled by locomotives on account of the grade. Hoisting engines and drums in connec tion with a frame structure 60 or 70 feet high, called a strip ping plane, are then located on the original surface beyond the outcrop. On the sloping face of the plane is laid either a single or double track which extends into the basin to the level of the shovels.

I. du Pout de Nemours & Company, Inc., Wilmington, Del. lie determined the proper loading and instructed a young blaster who completed the work with plantation labor, producing ditches which have challenged the admiration of drainage engineers of broad experience and have changed saltmarsh into savanna land. It usually happens that there is some workman on a farm or development operation who can he- trained by the agricultural salesman to do d\U:h~btating successfully. There is also an increasing number of competent contract blaster* who are available for important operations. As the action of dynamite in any soil is controlled absolutely by local conditions of texture and moisture, the proper loading and interval of place ment should always be determined by test shots in the ditch lint*. The main drainage problem, presented in the coastal plain interior is that of opening channels along branches and shallow swamps to take the run-off from torrential rains. While band ditching under such conditions is practically impossible, dynamite finds its most economical application there. A typical blasted ditch of this type is one from sk u> eight feet wide and from four to five feet deep. This can usually be made by three men, without cutting a right-of-way, at the rate of nearly a thousand feet a day. A great many such ditches have been blasted recently at very low cost in comparison with any other method, all reported data showing less than fifty cents a running yard under swamp cmidifionn- In Florida ditches have been blasted successfully and econom ically through the flatwoods areas, through Dade rock and through muck prairies. In the trucking regions of the state, flooded fields have been unwatered and crops saved by ditches blasted expeditiously and economically. Under Florida conditions the blasted ditch remains open longer than the dredged ditch, because in the former the excavated soil is widely distributed. in its groat malaria-control campaign the United States Public Health Service is using the blasted ditch to great advan tage. At Valdosta and Tifton, Georgia, and at: Bamberg.

The lower tap-root and the deeper laterals have no value lor dis tillation, but make good fuel when dry. The body of the stump, the first fifteen indies of tho tap-root and the oxprised laterals are wanted by the distillation plants in increasing quantity, and they pay from three dollar* tu four dollars and a half u ton for sound siumpwood, detail d mg on its quality and the location. A cord of such wood will weigh two tons, but the ton and not the cord is the unit to go by. Over must of the coastal plain, *tump* number from ten to sixty per acre in cultivated fields and occupy an average of sixteen square feet of tillable soil. In raw cutover land, the stand is furiy to one hundred and twenty-live per acre. In fields usually only the large stumps ere left and they run into tonnage rapidly, but as an average of many tests It ap|*tars that, five stumps to the ton of sound wood is a good basis for calculation and that five pounds of 40% Red Cross Extra will recover this amount of siumpwood. Stumps may be removed either by dynamite or by stump pullers. Up to a certain point, the stump puller is very efficient, Operated by an experienced crew under good conditions, it will put a stump ou top of the ground more cheaply than will dynamite, but. a pulled stump k only half disposed of. If the wood be wanted, the stump must he hurst with dynamite or sawed into sections and these split with, the axe. There Is no question as to the ability of the puller, either hand, 1)01*80 or power, to get stumps out of the ground if they afford a good hold above the surface, but for stumpwood salvage, where the stump must be broken into pieces, the puller is at a disadvantage. On the most efficient large-scale clearing operation in the South, where a puller i used instead of dynamite, it lias been found that, because of rotten-top stumps. low-cut stumps and buried stumps, at least of the total number must he blasted. On this operation a steam-power outfit capable of pulling stumps on forty acres from one setting is used, and the stumps are later broken up and sold to a distillation plant. For several years Mr. W. B*. Lamb, of Wadley, Ga. used a standard horsepower stump-puller and kept ac curate cost data. It cost him fifty cents each to dispose of his stumps,including pulling, yarding together and bum- lug. He changed to the dynamite method* obtained a lower initial cost, and had the;wood to audit against the cost of the operation. His puller was used before the price of labor attained its present level* -whereas the bl^mgwasdoiie tost winter, with dynamite prices sub stantially what they are today, The James' L* Waterbary Company, of Bradentown, of acres of small standing pine timber, an unusual operation.

Using a powerful steam outfit, they put their costs down from seventy-five dollars to about forty dollars an acre, but when they began to dear small, scattered tracts they turned to dynamite Itemise of the expense of moving the big machine. Coats there with dynamite are substantially the same as the lowest obtained with the big land-clearing machine. The stumpisan isolated unit and cannot he run through* machinelike corn through a hopper. The dynamite method is the unit method. When properly applied, dynamite is the absolute master of t.he stump. If the explosive in improperly placed, however, its great power is lost and in some eases it has left the stump a greater obstacle to tillage than before the blast. There are two methods of stump-blasting, the industrial and the agricultural, and only the latter is efficient from the farmer's viewpoint. By the industrial method, the body of the stump is shattered and knocked off at about the ground line. The taji-root is left high and the laterals are little disturbed. By the agricultural method, either the whole stump is removed as cleanly as n puller would do it with all roots attached, or the tap-root is cut off about twenty-four inches underground ami Cue body iif the stump and the laterals are heaved out in fragments. The agricultural method requires no more dynamite, but it demands a deeper hole bored at an acute angle into the tap-root. The industrial method uses a shallow hole at an obtuse angle; it does not make hole enough to confine the dynamite properly or to allow ife placement low enough to hoist out Urn stump. Wood reduction companies have used the industrial method and farmers have taken a great dislike to it, arguing from what they saw that dynamite was not an efficient stump remover. Dynamite applied in that manner is not efficient because too much grubbing is entailed, but a change in the angle of direction of the hole ami an increase in depth will get out the whole stump and practically eliminate grubbing. The method of boring holes by hand has given place to the more efficient method uf doing this work with power boring umv.l.itit:!!.

There were sixty-four slumps of all sorts, sound, rotten, large, small and buried, which were blasted so efficiently that neither the axe nor the grubbing hoe was needed afterwards except for filling tin? holes. From this acre the Duval Cattle Company gathered 18,800 pounds of sound wood for which it was offered a sum sufficient to pay for the blasting and the hauling and leave a surplus of three dollars and sixteen cents to be applied to filling the holes and making a complete job of clearing. These instances go to show that satisfactory stump-blasting is all a matter of proper boring; given the hole bored in the right place, at the proper angle, to a sufficient depth, the veriest amateur can do practically perfect blasting and clean the cavities absolutely, Such holes can be bored by hand cm small farm operations, but for salvaging the siumpwood and for important development operations the gasoline power boring machine is necessary. One of the most efficient machines drives a two-inch bit 32 inches into the tap-root in one minute and thirty-two seconds. One man operating the boring head and driving the mule can bore from one hundred and twenty-live to one hundred and seventy-five slumps in ten hours and two men can increase this number materially. A good blaster will load and shoot two hundred stumps In the ordinary working day without difficulty. _ Where large areas of raw land are to be cleared, blasting the stumps out first will permit the use of the tractor and the heavy grubber plows that make titling the land for farming practically a mechanical process throughout and greatly reduce the coat. There are some modern operations of this sort in progress at various places in the coastal plain, which, as they require a minimum of the -common labor that is so scarce today, are making excellent progress. They are making prairies at moderate cost and salvaging everything salable while doing it. ^ What does it cost to clear land? This is a natural question, but there is no specific answer.

Just as the tides of the ocean ebb anti flow, the transient throngs of Atlantic City visi tors, in spring, summer, laU and winter, surge in and out with unfailing regularity. Last year many millions of people from ail sections of the United States and from many foreign coun tries visited This famous resort. Business thrives bust whore many people congregate. The cosmopolitan character of the people who make Atlantic City their headquarters for a few days each year singles out this place as one where a manufacturer is likely to meet scores of his trade associates, even though their home addresses may rarge all the way from Los Angeles, California, to Portland, Maine, and from St. Paul, Minnesota, to Key West., Florida; for this famous resort, is one of the leading convention cities of the United States. In April, !9l, the Du Pout Company leased a istore at the corner of Pennsylvania Avenue and the Boardwalk in order to introduce the varied line of products manufactured by the Du Pont American Industries. It was the outgrowth of a sales pro motion idea to establish another route to public understanding, and to combat, the prevailing impression that- the Du Pont Company was engaged solely in the manufacture of explosives. The exhibit proved n revelation to thousands of visitors who learned for the first time that the company's products were wonderfully diversified in character and That they were em ployed in the mauufacUire of thousands of products of every day use. Interesting displays of Fabrikold. .Pyraiin, chemicals, paints and varnishes, all made by the Du Pont Company, were, shown along with articles made by other manufacturers who use Du Pont materials. This enterprise, started in a modest way, has attained propor tions scarcely dreamed of by the originator of the idea. The exhibit itself has doubled in size, and in order to house it properly the company was compelled to lease larger quarters in July of this year. Its popularity as an attraction may be judged by the fact that nearly 100,000 people have visited the exhibit during the past ten months. The new location in the Haddon Hall block is right in the heart of the hotel district, where thousands of people pass daily. The mail earner knows it as 1121-23 Boardwalk--midway between Pennsylvania and North Carolina Avenues..-but the casual visitor is apt to refer to it as "the Du Pont corner of the new building with the arcade in front, nearly opposite the Steeplechase Pier," The display windows are well planned to attract, attention. By occupying a corner location, with windows in front and on one side, the Du Pont Company is in position to show groupings of its related products in seven windows. Each one presents 21 different group of products. For example, one window contains products made of Pyraiin; another features Fabrikold, and so on. In artistic arrangement and general effectiveness, few display windows along the Boardwalk can compare with those of the Du Pont Exhibit. The equipment for illuminating these windows at, night was scientifically installed by an expert. Every effort was made to obtain the bast possible illuminating effects, and the result fully justified the attention given to this detail. The display window's of fashionable Fifth Avenue stores are not more effectively illuminated than are those of the Du Pone Products Exhibit. The visitor who enters the store immediately senses the distinctive character of the exhibit. There's an air of refinement, of quality, about the place that, takes it out of the- class of wholly commercial enterprises. The interior is not garishly decorated, not cluttered with merchandise, not too obviously dressed up, even though the primary object, is display.

Another visitor enters. He has been attracted by a window display of lamps finished with Pyralin enamels. lie is Mr. James, a buyer for a Milwaukee department store; he is slopping in Atlantic City only for the week-end and expects to leave for Now York the following Monday. His question is, ``Whore can I buy these lamps?" The Du Pont representative furnishes the address of the New York City sales office of the lamp manu facturer. By next mail a letter goes to the manager with full details and a statement that Mr. James will call. And the buying transaction is concluded there. Incidentally, -hundreds of inquiries are received by mail from all parts of the United States. For example, one business man writes: "Kindly inform me if your leather renower can he purchased in Pittsburgh., and who carries it." Another letter from Seattle, Washington, contains an inquiry about lacquers suitable for fishing reels. And the next letter is a request for the name of an agricultural blaster who can "blow a ditch through my land in Mississippi." Each request is answered promptly. A well-known office accessory, made in part of Du Font products, is on display in the exhibit room. Comes now the secretary of the Rotary Club, who has examined the display and hus caught the idea of adapting this accessory to serve the purposes of Ills organization. He wants tu know where he can procure- these accessories in quantity, and is rather surprised to find that, they are made? in bis home town. A letter reports the inquiry to the manufacturer and two or three days later the manufacturer's representative calls with a line of samples and the sale is quickly consummated. The buyer and the seller have been brought together through the service rendered by the Du Pont Produets Exhibit organization. "Good morning!" is the friendly greeting a Du Font repre sentative extends to three men now entering the .store. Their badges proclaim that they are delegat es attending a convention, on the pier. "1 just dropped in with my friends/' remarks the leader, "to show them a Fabrikoid traveling hug like the one I purchased four years ago in Omaha. It has stood the knocks of constant trawling and is still presentable. Just thought you might be glad to know that I am veil pleased with my purchase. If you don't mh:d. show these Allows some Fabrikoid luggage." The foregoing are typical instances of what happens, not occasionally, but many limes a day in the Atlantic City Du Pont Products Exhibit. People from all states of the Union Hock to Atlantic City, arid during their sojourn many of them find their way into the exhibit. They never fail to express astonishment at tho wonderful variety of the display's, and almost always they show a keen interest in the educational features that are so happily combined with the pleasure of seeing manufactured proiuels at their best. As an attraction, nowhere along the Boardwalk is there anything like it; as a national service institution it is a proved success, and no one knows this better than :ho manufacturers who use Du Font material in milking their own finished articles, and who display them along with the company's own products at Atlantic City.

Unearthing King Coal Continued from pogc H ears are raised by u hoisting engine and steel rope to the top of the plane and emptied. Coal ideally located for basin stripping is usually found beneath the surface of slight depressions or valleys, affording drainage ways. Streams, of little consequence in dry weather, are to he feared in ilood time if nearby stripping openings offer n way for the water to reach and drown out the urine workings below. Where choice stripping is found beneath a creek bed, new channels must be dug, sometimes beyond the outcrop, to make the coal available. For Lire same purpose timber ilumes, 8 by 15 feet in section and from one-half to three-quarters of a mile in length, have been built. In the ruse of shallow', surface veins and outcrop strippings, tire enllrery uf which Urey are a part; depends upon under ground mining for the major part of its eon! product ion. It can afford to wait until the stripping work h fully completed before touching the coal uncovered, but when the principal source of supply is in the thick seams, already mined, and the output is furnished mainly by coal from the uncovered pillars, stripping work and coal recovery are carried on concurrently, although each interferes with the other to some extent. A raeo is always on between the two operations. The stripping crew is usually hard pressed to keep ahead of the coal removers. The ideal method of completing the cover removal befoie touching the coal, as in the case of a shallow stripping, is not feasible in basin strippings; for it would mean that coal produo tion would cease entirely while u large and over-increasing amount of capital would be tied up for long periods of time. LACQUERS Protedfc and Beautify AMERICAN TOYS for American Kiddies * are protected from tarnish and made more beautiful through the use of the premier American Lacquer--DuPont.
