Up the Mountain Sides and through the Snow-Sheds on the Way to the Cascade Tunnel Re g . j . s . p a t .off. Ge l a t in Dy n a mit e Was Used Exclusively by A. Guthrie & Co., Inc., When Driving America's Longest Railroad Tunnel in Record Time Showing Rou tes of the Old and the l\'civ ('ascade Tunnels N JANUARY, 1929, the trains of lhe Great Northern Railway I began running through the longest Cascade tunnel, between Scenic and Rerne, Washington. The distance between these two points is now ten miles instead of the eighteen miles in volving 1,941 degrees of curvature. Passenger trains now save one hour and freight trains three hours by this new route. Although the tunnel has cost about fifteen million dollars, six miles of snow-sheds, costing the Great Northern five hundred thousand dollars annually to maintain, have been eliminated. The contractors, A. Guthrie & Co., Inc., of St. Paul, were given only three years in which to drive the 7.78 mile tunnel. In addition to the time element, there were complications such as encountering large volumes of water, a grade of 1.565 per cent, all tangent, and the possibility of drifting operations down grade being brought to a standstill at any time. These difficulties were overcome by driving a pioneer tunnel from both portals; by working four faces from three main camps; by sinking a 622-foot shaft to subgrade; by using the most modern methods, tools, equipment and materials--especially du Pont gelatin dynamite. By the application of modern engineering methods, skillful supervision of labor and machinery, and the efficiency of du Pont gelatin dynamite, Guthrie & Co. were en abled to break the world's record for tunnel driving three times in spite of the volume of water encountered which often reached 10,000 gallons per minute. This work is being carried on under the general direction ofJ. R. W. Davis, chief engineer, with Colonel Frederick Mears in charge for the Great Northern, and ./. C. Baxter, vice-president, A. Guthrie & Co., Inc., for the con tractors, with W. E. Conroy as general superintendent on the job.

Commentiiigon the year's work, President du Pont says: Manufacturing facilities were expanded. Additions were made to existing plants, new ones were built or acquired by purchase, and others are under construction. Plants were established at several places for the manu facture of nitric acid by the ammonia oxidation process. The Du Pont Rayon Company began operating a new unit near Nashville, Tennessee, and is now building two new plants, one at Richmond and the other at Waynes boro, Virginia, where cellulose acetate rayon will be produced. The Eastern Alcohol Corporation completed an addi lion to its property at Deepwater Point, New Jersey, which will also permit of manufacturing glycerin by the fermentation of molasses.

It is called the Chumstick Line, because for eight miles it follows the scenic Chumstick Valley. Climbing on a uniform and comparatively easy grade threHigh a rugged mountain country, the Chumstick Line Is made up of long stretches of straight track joined by easy curves. It bores twice straight through high rock ridges and cuts across steep hills and over deep ravines and rivers. Construction of the Chumstick Line was begun in July, 19x7, and it was placed in operation on October 7, 19x8. El ECTRIIICzITIOX The third phase of the improvement project is electri fication. When the first train moved through the new 8-mile tunnel on January ix, it was drawn by an electric locomotive, and at the same time the entire 75 miles of line between Appleyard and Skykomish was changed over to electrical operation. The cost of the electrification, including fourteen electric locomotive units, approxi mates $6,000,000. The work was done under the direction of the railway's engineers with Jackson & Moreland consulting. Both Westinghouse and General Electric locomotives are used. The purpose of the electrification is to afford clean and pleasant train operation through the long tunnel and to avoid the duplication of having both steam and electric motive power on the mountain district, the delays caused thereby, and expense incident thereto. Without electrify ing the entire district such duplication would be necessary on account of electric operation of the tunnel and steam operation outside the tunnel. An unusual feature of the Great Northern's electrification is the combination of the alternating and direct current systems. Alternating cur rent is used for transmission from the source of power to the locomotives and direct current is used in the traction motors. The alternating current transmission system has the advantage of minimum power losses, minimum copper requirements, and strong overhead construction at moderate cost. The locomotives themselves carry the transformers and motor-generator sets which change the high tension alternating current to low tension direct current. The type of traction motor which is most rugged in construction, most economical to maintain, and most flexible to operate is thus made available. The combination gives a self-contained locomotive with an unlimited range (Continued mi page 24) Above--Inside the finished tunnel.

The Sheet shooter uses his favorite shotgun, rather tban one of special type, because the ordinary gun is best adapied to breaking largcls thrown as they are in Sheet, and also because ihe gunner warns to improve his skill in the field or on the marsh. One rule of the game prohibits raising the gun to the shoulder until the "bird" has left the trap and is actually in the air, this to develop the "quick-on-the-trigger" technique one must have when shooting game birds. The chief advantages of this sport are, first, that it offers a series of shots similar to t hose encountered in act ual hunting, and, second, that the shooter may use the same gun lie is accustomed to hum with in the field. If it meets his requirements for hunting, it will serve equally well in bringing down Sheet targets.

These sources are all connected up and give unusual assurance of continuity of supply. Two transmission Hues arc used to protect against interruption of power supply through accident to one of the lines. Sig n if ic a n c e o f Imp r o v e me n t s The completion of the new tunnel and of thirty-four miles of easy, high-speed track replacing forty-three miles of steep and winding mountain line, together with the electrification of 75 miles of road, marks a great step forward in bringing the West Coast closer to the East. These improvements eliminate from operation the prob lems incident to crossing a mountain barrier, and will expedite the flow of commerce and contribute to the comfort of travelers, as well as save time. Timins will cover the distance between Seattle and Spokane 00 shorter schedules than ever before. While these savings and advantages over a period of years will repay the cost and carrying charges of the improvements, the public as well has a vital and im mediate interest in these and all similar improvements in the nation's transportation facilities. Such improvements constitute an elemental achievement that fixes shorter distances and lower grades, and these in turn set up new standards of performance, resulting in benefit to all who are affected by the advancement of transcontinental transportation. Completion of this magnificent threefold improvement project is a source of the greatest satisfaction to the directors and officers of the railway company, because it brings the Cascade Mountain district up to the standard of operating efficiency on the other divisions and realizes a cherished ideal of James J.
