ADAPTATION OF STANDARD IV. 
‘The open-court warehouse has very much the same use as Standard 
III. This warehouse is readily adaptable for use as a large public 
storage plant. This is especially true where the house occupies a full 
block. Where available land is in a narrow strip, it is frequently 
necessary to use Standard III, but in most cases where the warehouse 
has a storage capacity of not less than 10,000 or 15,000 bales it is 
advisable to use the open-court type. 
STANDARD V.—STANDARD FOR HOLLOW-SQUARE OR OPEN-COURT WAREHOUSE OF 
FIRE-RESISTIVE CONSTRUCTION. 
Construction of building.—This standard requires that the building 
should be constructed of reinforced concrete or standard brick through- 
out. The building should be constructed of an approved mixture of 
concrete (where concrete is used), properly reinforced with steel. 
Concrete blocks (whole or hollow) will not be considered reinforced. 
The area of any compartment should not exceed 2,950 square feet 
(59 by 50 feet) and the area of any compress compartment should not 
exceed 5,644 square feet (83 by 68 feet). (See fig. 5 for approved | 
diagram). The height of any storage compartment should not exceed 
13 feet 8 inches at the lower side or 16 feet 8 inches at the higher side. 
Walls, doors, etc.—The outside walls should be at least 9 inches 
thick if concrete, or 13 inches thick if brick. Division walls should be 
4 inches thicker than required for outside walls. The wall around the 
compress tower above the main roof should be 6 inches thick and 
should be constructed of reinforced concrete. All walls should have 
parapets 3 feet above the roofs of the same thickness as the wall. 
The parapets should be parallel with the contour of the roof and 
properly coped if built of brick. The floors should be of noncom- 
bustible material, with no air space underneath. To meet the stand- 
ard, the building should have a concrete roof 4 inches thick, covered 
with approved composition roofing. All columns, girders, and 
cross girders supporting the roof should be of reinforced concrete. 
No windows should be allowed except in the office and compress 
tower. Doors should be allowed only in outside and court walls, 
and these should be fully standard in all respects. Each storage 
compartment should have one or more standard fireproof doors, 
not more than 50 feet apart, opening outward. On the court side of 
the walls the Coors must be placed before each tier of cotton. The 
court should be at least 200 feet wide, and no combustible material 
of any kind should be permitted in the court. 
Arrangement, etc.—Not over 600 bales should be stored in any 
one compartment. The cotton bale should be laid flat on the side, 
and piled not to exceed 5 bales high. The sizes listed above will 
allow the storage of 600 standard bales, five tiers high, 120 bales to
