THE cold air vs. BRINE SYSTEMS OF ARTIFICIAL 



REFRIGERATION. 



Six barrels of apples, all of the same variety, were marked 

 and sent to each of tw^o cold-storage systems in Boston on 

 Nov. 20, 1899. On Feb. 5th a barrel from each system was 

 taken out and the fruit counted, and data taken, as shown in 

 the accompanying table. Each month thereafter until July a 

 similar lot was received, and, like the first, the results from 

 examination are tabulated in the same table. 



From the table (see next page) it is seen that with the ex- 

 ception of the first month's comparison there were more 

 spoiled fruits in the brine than in the cold air. As the expe- 

 riment continued it is also apparent that the cold-air storage 

 was preferable. 



The following letter was received from Manager G. H. 

 Stoddard, of the Qiiincy Market Cold Storage Company of 

 Boston, Sept. 4, 1902 : 



" For nearly all goods that are to be stored at a tempera- 

 ture above 32 degrees F. we prefer the air-circulation system 

 to the brine system.'''
