DuPont Magazine From a painting by S. M. Arthurs The early settlers of the West followed the natural watercourses, and occasionally they had to teach the Indians to respect the dependability of du Pont gunpowder.

When the first du Pont powder was made nearly a century and a quarter ago-- chemistry was not an exact science. Today, the chemical engineer with the vast resources of modern science at his disposal controls production from raw material to finished product. To chemical control, through research and experiment, is due that unvary ing quality which makes the "Du Pont Oval" a symbol of excellence everywhere. ; *>>. E. I. du Pont de Nemours & Co.

L)u I'Oiii i'i Exhibit always attract favorable attention ATTLANTIC CITY, New Jersey, is perhaps the nation's most famous ycar-rcu health and pleasure resort. Its location, climate, its sport and recreational facilities attract people from every quarter of the globe.. With a permanent population of con siderably less than 75,000, it is claimed that 2.0,000,000 people visit this increasingly popular resort each year. As a convention city, too, it ranks high. So many national organizations hold their annual meetings there each year that now a project is under way to build a con vention hall that will be the largest one in the world. Every town has its Main Street, Atlantic City has a most unique one--the Boardwalk, which extends eight miles along the ocean front and Is sixty feet wide in its central section. On the land side are million dollar hotels, oriental bazaars, inviting toy stores, theaters, exhibits, dainty tea rooms, beauty parlors, fashionable shops and stores and business places of all kinds, close packed for many blocks. On the side toward the sea six great ocean piers house a vast array of popular attractions. Probably ninety per cent of all the people who visit Atlantic Ci ty spend most of their time on the Boardwalk-- the one great recreation center. They bask in the sunshine, they mingle with the crowds, they Ml their lungs with the balmy air from the ocean, and in an environment of life and light and color they are renewed both in body and mind. Up and down the 'Walk they stroll, care-free and eager to exa mine and study whatever may attract their attend011. And so it is that advertisers, catering to Board walk crowds, really reach the nation at large, or a cross section of it, under especially favorable circumstances. That explains why Heinz, Atlantic City's first perma nent exhibitor, built a great ocean pier as a show place for his famous "57 varieties;'* why the du Pont Company next chose a Boardwalk location to exhibit its family of products, and why the Crane Company, notably, and a dozen or more other national advertisers since then have established exhibits of various kinds. A typical Easier throng. This pkotograph teas tahert last year MWtOOfi people promenaded, up and down the Boarthvulk- The Pont Products Exhibit, which is located across the 'Walk from The Dn Pont Products Exhibit is just ten years old this month. It was first opened to the public lit 1105 Board walk on April 16, 1916- Three years later it was removed to more spacious quarters at 11x1-13 Boardwalk, the present location. It is known that at least 161,000 people entered the exhibit last year. The total is conservative, for during rash periods it was impracticable to make a per capita count. And it would be idle to speculate on the number of passers-by who paused to examine the attractive window displays for which the Du Pont Products Exhibit is noted. 4 =5^0 DU PONT PRODUCTS TO THE MILLIONS?

Visitors entering the exhibit are likely to misinterpret its character, for at lirst glance it doesn't look like an exhibit at all. The merchandise displays in showcases and on shelves.. the appointments ot the room generally --con vcv the impression of a high-class filth A venae shop. C.loser inspection, however, dispels this illusion, for beside each Jisplav h a neatly lettered card identify ing the merchandise hv the maker's name and address and showing the name al the du Pone product used m its manufacture. What intrigues visiters most is probably the great mini her and variety of articles shown. Man}- of them express amazement that so main articles of common use in i heir homes are produced, with da Pont materials they never heard of before. The exhibit visualizes the part industrial chemistry plays m die maiiufacturuig activities of the nation. It promotes a better understanding of the character and utility ol du Pont products. lr presents an advertising advantage to the manufacturers who show merchandise there, and ikewisc builds prestige for the du Pont Company. And it educates the public. But the exhibit accomplishes more than that, for many industrial and commercial leaders come to Atlantic City from all parts of the coumrv. Rarely ever do they leave the resort without vistdug this interesting exhibit. Many a manufacturer scrolls in "just to look around" and walks out briskly with a brand new idea of adapting some du Pone product to his own use. To cite an instance: A manufacturer strolled in the exhibit one day and as a result of that visit he fits since made use of about 500,000 yards of Fabrikoid. His products arc well known from coast 0 coast.

Of this amount more than sixty per cent was deposited on the place prepared tor it at the foot of the bluff, and ninety per cent of tin's pile was of crusher she, thus reducing secondary blasting to a minim 11 m.

Premature explo sions have been caused where straight dynamite was used 01 sprung holes by loose pieces of rock with a little dyna mite between them sliding against each other while the bore hole was being loaded. Of quarry accidents which have been reported to m during the last live years, by far die greatest number occurred where straight dynamite, usually a high grade, 40% or 60% nitroglycerin, was in use. Some of these accidents were probably caused by friction between a gritty tamping stick and the bore hole with the dynamite smeared in between. Several were caused by spaiks from a steam shovel or locomotive dropping into the bore hole. Two or three were probably caused hv men smoking while loading and either dropping a lighted cigarette or Ammonia dynamirc is less sensitive to this kind o! a match into the bore hole.

Back of the Ashhuwi Plant that is, to the west--is a fairly Ktecp-sideJ ridge which at this point separates the Valiev of the Missued qd from that of Salt River.

These structures consisted of an inside rock-w;Jkd space, roughly square, and about ten feet on a side. There is a break in one side, near the corner, which appears to have been an entrance, and outside this hwak is another wall, extending along twru sides of the square, parallel to the inside walls, and forming a passage, or corridor. Hi ere is no indication of there having been an}' root o\cr the buildings. We will leave it to the reader ro figure out to his own satisfaction the use to which the original structures were put- Some people say they were lores made by the Mound Builders, and that the outside wall was built ro protect the entrance, and incidentally the inmates, Irom arrows and other unpleasant things. Tins may be the c u m;, and dispute is idle. It occurs to the writer, however, that a garrison which was able to spit 00 its hands, and make other war-like greatest, in a space ten feet square, was rather scanty in numbers, anil that this fact would have opened ro an ;n lacking force the alluring alternative of passing a hundred yards or so to one side or die cither, and ignoring the garrison entire] \\ which would have been verv hcut:Hating indeed.
