COTTON" WAEEIIOTSE CONSTRUCTION.

height of the platform and should extend through these platforms so 

 as to cut them off into divisions corresponding to the compartments 

 in the warehouse. 



Roof. — The roof should be of light mill construction, with a mini- 

 mum thickness of 2 inches splined or tongued and grooved, supported 

 by timbers single thick (not less than 6 by 8 inches) and spaced 8 or 

 10 feet apart. One end of the timber should rest on brick ledges or 

 division walls, corbeled out to form suitable supports. The posts 

 should be not less than 8 by 8 inches, and all corners of timbers 

 and posts should be chamfered. Monitors, skylights, and roof lan- 

 terns should not be allowed unless they are made of wired glass, 

 properly set in metal frames. The roof should be covered with 

 gravel or approved composition. A roof of ordinary open-joist con- 

 struction covered with gravel or approved composition will be classed 

 as standard, but if automatic sprinklers are to be installed, it will be 

 necessary to have from 25 to 50 per cent more heads than are neces- 

 sary in the case of a roof of mill construction. 



Samples. — All standards should require that the cotton be graded, 

 and all books showing the number of bales, weights, and marks 

 should be kept in some locality a sufficient distance from the ware- 

 house or in a separate fireproof compartment or vault, so as not to be 

 damaged by fire. Such books and samples also should be kept in a 

 fireproof compartment or vault. 



Boors. — The ends of the compartment should have as many doors 

 as possible, and in no case should the doors be more than 3 feet 

 apart. They should be heavy and securely made, hung on strong 

 hinges, and should open outward so as to facilitate the rapid move- 

 ment of cotton in case of fire. 



Ventilators. — The top of each compartment should be provided 

 with one or more approved metal ventilators. 



Fire protection. — A connection of not less than a 6-inch pipe with 

 a city water main of equal or larger diameter is necessary. One 

 standard hydrant for each three compartments should be placed 

 opposite the front or rear ends. Not less than 100 feet of approved 

 2^-inch cotton, rubber-fined hose should be kept attached to each 

 hydrant. Six casks and 12 pails filled with water must be provided 

 for each 600 bales storage capacity.
