 either end of the gallery. 



Two men, "F" and " B," moved bricks to and fro continuously and 

 stacked them. They wore the Fleuss dress, and the canvas covers of the 

 breathing bags were wet with water, and now and again a full stream of 

 oxygen was turned on in order to wash out the breathing bag and cool the 

 soda. 



The oxygen allowance was reduced to 0.75 liter per minute and found to 

 be ample at these temperatures. The men were stripped to the waist. 



" B " worked up to the end, and his pulse temperature soon returned to 

 normal after he came out. 



In the modern battle-ship men are confined very largely to places 

 artificially lighted, and ventilated by air driven in by fans through 

 ventilating shafts. The heat and moisture derived from the bodies 

 of the men, from the engines, from cooking ranges, etc., lead to a 

 high degree of relative moisture, and therefore all parts of the iron- 

 work inside are coated with granulated cork to hold the condensed 

 moisture and prevent dripping. 



The air smells with the manifold odors of oil, cooking', human 

 bodies, etc., and the fresh air driven in by fans through the metal 

 conduits takes up the smell of these and is spoken of by the officers 

 with disparagement as " tinned " or " potted " air. This air is
