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.

 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

 4 inches thicker than required for outside walls. The wall around the 

 compress tower above the main roof should be 6 inches thick and
