 and have a diameter of approximately 8 inches each. 

 These pipes stand closely side by side in a single rank. 

 The entire row sits in a wooden trough, which carries

 into the cooling tubes by being shoveled into the 

 trough already mentioned. The entire storage room

 freezer. Any practicable temperature may be secured
