buccess with Gas Storage 



^ visit to Cornell has laaue ae "all het up" over gas 

 storage. They have siOO oushels ol rAcIntosh now in storage to be 

 taken out about August cO with coni'iaence that they will De in gooa 

 condition. 



The aetails of gas storage are briefly these: (l) a 

 gas-tignt storage room, (£) a teiiiperatur'^ close to 40°-c . , anu (o) 

 maintenance of a storage atraospnere containing 270 oxygen ana b'/o 

 carbon aioxiae. Tnis concentration of 00.- is built up as a result 

 of respiration in the fruit, within two or three '-veeks. lifter that 

 the carbon aioxiae content is controllea by passing the storage at- 

 mosphere through caustic soaa solution, ana the oxygen, by aaraitting 

 outsiae air. 



The storage room is maae gas-tignt by means of a sheet 

 metal lining, the joints of which are sealea with special ^lutty, 

 ana a gas-tight aoor sealea with vaseline. Tne aoor has u sliuing 

 glass panel for observation ana for aumitting air, the eages of 

 whicih are likewise sealed with vaseline, a. gas analysis is maae 

 u'l^ily to facilitate control. This operation is a simple one, re- 

 quiring only £ or iD minutes. I coula ao it, ana so coula you. In- 

 vestigators estimate that a cola storage room can be maae gas-tight 

 at a cost of about 10 cents per busiiel Capc^city.

 Vvhetner one is better than anotner nas not oeen shown, ijifforences 

 in effectiveness may appear, but it is trobaole that all will be
