the
United States at points selected by the War Department. The camps were
carefully laid out by experienced town planners and engineers to give
best results considering all viewpoints.

[Sidenote: Extent of a typical National Army cantonment.]

[Sidenote: Roads constructed and improvements installed.]

A typical cantonment city will house 40,000 men. Each barrack building
will house 150 men and provide 500 cubic feet of air space per man. Such
a cantonment complete contains between 1,000 and 1,200 buildings and
covers about 2,000 acres. In addition, each cantonment has a rifle
range, drill, parade, and maneuver grounds of about 2,000 acres. In many
cases all or a large part of the entire site had to be cleared of woods
and stumps. The various military units were located on principal or
primary roads--a regiment being treated as a primary unit. About 25
miles of roads were constructed at each cantonment, and sewers, water
supply, lighting facilities, and other improvements installed.

[Sidenote: The special buildings required.]

An infantry regiment requires 22 barrack buildings, 6 for officers'
quarters, 2 storehouses, 1 infirmary building, 28 lavatories, with hot
and cold shower baths, or a total of 59 buildings. In addition to the
buildings necessary for the regimental units, each cantonment has
buildings for divisional headquarters, quartermaster depots, laundry
receiving and distributing stations, base hospitals having 1,000 beds,
post exchanges, and other buildings for general use.

[Sidenote: Remount stations.]

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.
