THE DU PONT MAGAZINE Aimost as easy as wishing... whenyou apply the radiant colors of DUCO C~A T O matter how little you've handled a \/ brush, the results you get with Duco \^are always gratifying. Duco dries so quickly that it saves the usual fuss and bother of an upset house. Refinish a chair in the afternoon and it will be perfectly safe to use that very evening. It's almost as easy as signing your name to bring the radiant colors of Duco into your home. You will find uses for Duco in every room. In fact, wherever there is a surface to take a finish, that surface can be made more beautiful and more enduring by the application of a Duco color, a rich, full-textured Duco stain or clear transparent Duco, which shows the natural beauty of the wood grain. Duco can be applied either with a brush or small hand sprayer, and it dries with con venient rapidity. Neither too quicklv, nor too slowly. There's a du Pont dealer in your neighbor hood who carries genuine Duco, made only by du Pont. Look for the green label, the du Pont oval trademark, on every can you buy. Realizing the importance of expert advice on home decoration, the makers of Duco have asked a group of the most famous interior decorators to prepare a book of approved color combinations. This book, "A Color Scheme for Every Room," is filled with illus trations of model rooms of every type, with instructions that will enable you easily to achieve, in your own home, the same effective results.

It is also true that most of the chests on the market today are not so constructed. The Syracuse Cabinet Company... one of the oldest chest manufacturing firms in the United States with headquartets at North Manchester, Indiana... is making a line cf chests constructed with genuine walnut on the exterior and with a lining of solid cedar. They are made to match any PiQCQ of furniture in the home--In plain, period and tnodern designs. Furthermore, all chests manufactured by the Syracuse Cabinet Company are finished with Coco, the Best finish we can obtain. Our company has found that when dealers display and 0 cr ur chests finished with Duco, it is not necessary for them to explain to their customers how this finish is put On, or whether it will give service at whether It will he durable, because the customer usually knows as much about Duco as the dealer himself. The name of the Syra cuse Cabinet Company is identified on every chest leaving the factory; so also is the Dutu trade-mark. Due to the Modern production methods used in our plant, high -grade Walnut chests with cedar interiors are available at a price Within the reach of every housewife and bride-to-be, A . c^ar chest, therefore, is not a luxury. It will pay for itself 0ne season through the savings effected by preventing the destruction by moths of valuable garmai ts. A pro perly constructed chest, therefore, becomes a necessity rather than a luxury. Upon entering the North Manchester Pyltit the first thing that Impresses the Msifor is the natural aroma of the cedar f*rucess being worked. The wood JS ^pped In carload lots to the Syracuse Cabinet Company from the mountains of Tennessee. It is necessary to have it kiln dried in order to take out the moisture and to eliminate warping afterwards. Cedar lumber must be dried by a process entirely different from any other in order to preserve a sufficient amount of the natural cedar oil in the wood. After the cedar boards are removed from the kiln, they are sent through modern, powcr-dri ven, electrically oper ated machines where they are cut into various lengths, planed, ripped, edged and glued into panels. They are then sent through the veneer department', and genuine walnut veneer is applied with waterproof glue properly seasoned and scientifically handled. After these panels are sanded, polished and inspected, they are ready to be assembled. Only modern methods of production arc used in the Syracuse Cabinet Company's plant. All chests are assem bled on a. urn i: basis. Skilled craftsmen are employed, each one having been trained to do his particular work well and efficiently. In the assembling department beautiful panels, overlays and carved moldings are put on, and soon a chest appears ready for rhe finishing department. How ever, before passing to this department, each chest is again thoroughly inspected. In the finishing room various decorative effects are ob tained. Some chests are shaded and high-lighted and, as stated, all are finished in Duco. The Duco finish not only protects but also enhances the inherent beauty of the wood. The finish h moisture-proof durable and ready for lifetime service. The Syracuse Cabinet Company's chests are sold by good dealers throughout the country. They arc rec ommended by department stores and leading - furniture houses, because cf their superior construction and the high-grade quality of all materials used in their manufacture.

The first half of the project, which has already been started, includes the sinking of eight shafts and the construction of about thirteen links of horseshoe-shaped tunneling about twelve feet wide. The explosives engineer of today attacks such tunneling with confidence, for he is equipped to solve the many problems which are peculiar to each job. In this Boston work six of the shafts were planned for the purpose of providing headings for driving the tunnel. It will not be sufficient that dynamite merely break up the rock under ground in order to prepare a path for the great waterwayThe explosives engineer directs that on this job the holes shall be drilled m the rock and shot hi such a way that the blasting will not crack the stone in such small pieces that they must be shoveled, for shoveling can not be economically done on this project. Surely dynamite is a wizard with a magic power to break clown great cliffs at one blast, to shatter rock masses into small pieces, or to cut up huge stones into blocks of desired size. The explosives engineer realizes chat to use this magic to the best advantage he must not only have scientific knowledge and experience but he must have vision and sound judgment. It is by his command that explosives are building the modern world.

Occasionally, however, a piece of work is made interesting because one project one year leads to another the next, so that there is continuity. That affords the opportunity to study the results of previ ous blasting services year after year. The work on the farm of Edgar Brown near Savannah, New York, was of that type. On Mr. Brown's farm there was a three-acre area filled with stumps and second-growth timber. His problem was first of all to make this valueless land yield some sort of crap revenue. Mr. Brown had heard and read of ditching and drain ing with dynamite; how land of the type he intended to drain was reclaimed and made to yield valuable crops. Kc wanted his land working for him and that involved the question of getting rid of the water in the muck area. But how and where? Now the Brown farm is divided by a public highway running north and south. The property line, to the south, prevented the owner from seeking a drainage outlet m that direction.

It seemed to the Connors Hoe and Tool Company, Inc,, that a new and improved tool handle would find a ready market. Men wh o Ji ad been in the bus\ loess for years, and who knew what a garden tool should be, busied themselves to find a suitable material for handles. After some experimenting a steel tubing was developed which was strong enough for the purpose and of about the same weight as a wood handle. But it had one disadvantage... steel is not kind to the human hand, It 1S hard and unsympathetic- and has a way of heating UP quickly on a hot day, while remaining chilled on a cold day. In all kinds of weather it is uncomfortable. ' Why not cover the steel with some insulating material which would be as easy on the hands as wood? More testing and discarding followed, and then it was found that cork-faced Fabrikoid provided a good, smooth, non-blistering grip and the necessary insulation. The method of applying Fabrikoid to the tubular steel handles is interesting. The material is cut into one-inch strips, then coated with a strong, waterproof adhesive, and wrapped spirally under pressure by a specially de signed machine. A steel ferrule, clamped over the end of the cork, prevents unwinding. That there was a real need for tools with dependable handles has been proved by the growing demand for `'Corksteel'5 products. They are strong and enduring, and cost about the same as similar first-quality tools whh wood handles. Since the too! and its handle are both made of steel, riveted or welded together, implements of this kind give lasting satisfaction to their users.
