Collection Of War Engineering Material

At the office of the Chief of Engineers, Washington, there is a unique collection of engineering material used and developed in the present war. It. is a most interesting group of war devices, from the special trench shovel that excavates both gas and water, to the standard gage locomotives that were sent to France so complete that they were lifted from the ships by cranes, placed on the-rails on shore, filled with water, fired up, and moved out from underneath the cranes under their own steam. Everything is exhibited either by models, or by photograph where the original samples are too large to admit of demonstration in an ordinary office. The forestry section has an interesting exhibit of the wonderful work clone in France; where, owing to the shortage of coal and the necessity for burning wood, the Forestry Unit of the A. E. F. in one month stacked up 60 mi. of cord wood (80,000 cords); also cut 6.6 mi. of timber, stacked 12 ft. long, and 10 ft. high, containing 50,000,000 hoard feet of sawed timber.
