Professor Sears. They would freeze quicker loose sim- 

 ply because the cold air can get at them more quickly. I 

 suppose that if you put in too much salt and get the room 

 too cold the loose apples would freeze much more quickly 

 than those in the barrels, simply owing to this fact, — the 

 barrel is quite a protection because it doesn't allow the air 

 to circulate quite so freely. I think in that connection all 

 fruits, certainly all apples, should be stored in tight pack- 

 ages. I don't believe in the ventilated packages. 



Mr. MuNKOE MoKSE. Do 3"0U separate bunkers for each 

 room, or are they all supplied from one bunker ? 



Professor Sears. We have six of these bunkers and each 

 has its coil of pipe, and that coil is connected with a separate 

 room, one bunker and one pipe for each of the six rooms. 



Mr. Fkost. Should 

 the storage room be be- 

 low the ground ? 



Professor Seaks. If 

 you can get it l^elow the 

 ground the temperature 

 will fluctuate much more 

 slowly, and it is very 

 desirable so far as in- 

 sulation is concerned. 

 The 10th of January last 

 year broke all records 

 outside, and the tem- 

 perature in the under- 

 ground room I refer to 

 then stood at just 32 ; 

 w^e kept it closed, and it 

 rose gradually to 38 on 

 the 1st of April. It 

 took it all that time to 

 rise from 32 to 38. If 

 it had been above ground 

 it would have risen much 

 more rapidly, even with 

 the best of insulation.
