vision for tlie joining of several buildings, into buildings 18 by 36 

 feet, 18 by 54 feet, or larger. They are adaptable for either guarded 

 or honor camps and for all the pui'poses of such camps, as for con- 

 victs' sleeping quarters, mess halls, kitchens, storehouses, lavato- 

 ries, and baths, and for guards' and superintendents' quarters, or 

 office buildings. As sleeping quarters each 18 by 18 foot building 

 will accommodate a maximum of 16 persons, by the use of double- 

 decked metal cots arranged 

 along each side of the build- 

 ing with their length per- 

 pendicular to the walls, 

 which arrangement pro- 

 vides for an aisle of 4| feet 

 down the center. With 

 this maximum number of 

 inmates, the building pro- 

 vides approximately 20 

 square feet of floor space 

 and 200 cubic feet of air 

 space per inmate, which 

 allowance, in view of the 

 excellent means of venti- 

 lation provided, is entirely 

 adequate. Window spaces, 

 42 inches deep, closed by 

 solid wooden shutters and 

 glazed sashes, extend the 

 full length of all sides of 

 the building, with the ex- 

 ception of the space neces- 

 sary for doors, and by open- 

 ing these windows in sum- 

 mer it is possible to keep 

 the air inside the buildings 

 down to the temper atiu'e 

 of the outer air. The shut- 

 ters and windows are hinged at the top and swing outward, and when 

 they are open they act as awnings for protection from the weather. 

 All doors and windows are provided with 16-mesh galvanized-wire 

 screens. Security can be provided in guarded camps by barring the 

 windows, by chaining the prisoners to their bunks, and by the in- 

 sertion of a cage vestibule inside one of the doors of the sleeping 

 quarters as a station for the armed night guard. Such a cage may be 

 constructed of No. 5 steel-wire scn»ening with a 2-inch mesh (lig. 8).
