At several of the cantonments remount stations have been provided, some of them having a capacity to maintain 12,000 horses. [Sidenote: Other necessary camps.] In addition to the National Army camps, plans were made for the construction of 16 National Guard, two embarkation and one quartermaster training camp, but the construction of these items did not involve so large an expenditure as the National Army camps, as provision was made for fewer units and only tentage quarters for the men in the National Guard camps was provided. Modern storehouses, kitchens, mess shelters, lavatories, shower baths, base hospitals, and remount depots were built, and water, sewerage, heating, and light systems installed at an expenditure of about $1,900,000 for each camp. [Sidenote: The demand for construction and supplies.] [Sidenote: Savings effected by standardization.] With the advent of the United States into the war, there has appeared not only one of the world's greatest builders, but the world's greatest customer for supplies and human necessaries. We have not only to equip, house, and supply our own army, but meet the demands arising from the drainage of the resources of the entente allies. Small shopping and bargaining are out of the question. Enormous savings were, however, effected, due to the fact that materials were purchased in large quantities and consequently at a much reduced price. Standardization of sizes saved from $5 to $6 per thousand feet b. m. on lumber, and a further saving of from $3 to $11 over prevailing prices was effected by the lumber subcommittee of the Council of National Defense. The Raw Materials Committee effected similar savings in prepared roofing, nails, and other construction materials. The lead subcommittee procured 500 tons of lead for caulking pipe at 3 cents less than market price. When it is considered that this construction work is, next to the Panama Canal, the largest ever undertaken by the United States, the country is to be congratulated on having available the men and materials to accomplish the feat of providing for the maintenance of the newly organized army in so short a period. [Sidenote: Extensive construction work for National Army.] I have described at length the work of building necessary for the National Army camps, but at the same time extensive building was necessary at the 16 sites selected for the mobilization and training of the National Guard. While the National Guard troops were themselves quartered under canvas, many wooden buildings and storehouses had to be constructed for their use and, of course, the important problems of water supply, sewage, and hospital accommodations required substantially as much provision upon these subjects as upon those selected for the National Army.
