ed men,
and those selected were soon on their way to training camps.

To house this great army, the government had to build a great system of
army camps. Contracts were given out soon after war was declared and
the camps began to spring up almost overnight. The government built 16
draft army camps and 16 national guard camps. There were also numerous
other military zones where smaller bodies of troops were trained. The
draft army camps were located so as to house the men from different
sections of the country, as a glance at the list of camps will show:--

Camp Devens, Massachusetts; Camp Upton, New York; Camp Dix, New Jersey;
Camp Meade, Maryland; Camp Lee, Virginia; Camp Jackson, South Carolina;
Camp Gordon, Georgia; Camp Sherman, Ohio; Camp Taylor, Kentucky; Camp
Custer, Michigan; Camp Grant, Illinois; Camp Pike, Arkansas; Camp
Dodge, Iowa; Camp Funston, Kansas; Camp Travis, Texas; Camp Lewis,
Washington.

These great cities were built in less than four months. If all the
buildings of the sixteen cantonments were placed end to end, they would
make a continuous structure reaching from Washington to Detroit. Each
one of these camps housed between 35,000 and 47,000 men. The sixteen
cantonments were capable of providing for a number equal to the
combined population of Arizona and New Mexico. The hospitals of these
camps were able to take care of as many sick and wounded as are to be
found in all the hospitals west of the Mississippi in normal times.
Each camp covered many square miles of land which had to be cleared of
trees and brush before buildings and roads were completed.

used in every army cantonment in the United States. The tar-paper
structures in the foreground were used for storehouses and general
out-buildings. In the background are the well-built barracks. The

To keep these cantonments clean and fit to live in, large numbers of
sanitary engineers, medical officers, and scientific experts were kept
busy planning and installing the most modern sanitation systems. To
command this great army, the government built officers' camps where men
best fitted were trained to be officers, and were then sent to the
cantonments to help in changing the American citizen into a soldier.
War was declared in April, and by the hot weather of summer America was
sending troops by the tens
