THE FRUIT INDUSTRY i.\ NEW YORK STATE 



The up-to-date plant for today is the gas producer, which is 

 run by gas or oil engines instead of boilers. Either one of these 

 machines can be used very economically, and, compared with the 

 boilers and steam, in the ratio of 7 to 1 in the former with 20 to 

 1 in the latter; that is, by the old method of boilers we made 

 seven tons of ice with one ton of coal, while vvith the new method 

 of gas producer or oil engines we can make 20 tons of ice with 

 1 ton of coal. This same ratio applies to refrigeration, but it 

 doubles its capacity when the temperature is above 32 degrees. 



The making of artificial ice also for commercial purposes is a 

 great blessing, as it is chemically pure, and, since the sources of 

 natural ice have become contaminated and unfit for household 

 use, it should always be used in preference.

 SMALL PLANTS FOR FARMERS 



Since most of the large cities and towns demand that the milk 

 supply shall not be above 60 degrees F., it is necessary to have 

 the milk cooled before shipment, thus necessitating refrigerating 

 plants for farmers and dairymen. Therefore, hundred of these 

 small plants are being erected by farmers and used for holding 

 fruit as well as milk.
