WAY FOR DRUGGISTS TO BEAT THE ICE TRUST. 



Druggists who have a large soda water trade are finding that the 

 Ice Trust is as much of an ogre as is the Coal Trust or any of the 

 other trusts. Some druggists have found practical ways of frus- 

 trating the extortionists, and in the June issue of The Soda Fountain 

 an interesting account was given of the refrigerating plant which 

 has been installed by a prominent Philadelphia pharmacist, who for 

 a vear or more has been free from paying tribute to the Ice Trust, 

 while at the same time he has preserved an even temperature all the 

 time in his cooling apparatus. 



This pharmacist makes ammonia do the work of the frost king 

 by forming a layer of ice about the iron coil in a tank full of filtered 

 water. As the ice is formed about these coils the temperature of 

 the water about them falls, and when the thermometer registers 33 

 degrees the motor stops and no more ice is formed until the temper- 

 ature of the water goes up a few degrees. This rise takes some 

 time, for water absorbs and parts with heat or cold very slowly. 

 This colled, filtered water is pumped into the tanks of the fountain 

 where the soda water coils are located, while beneath them, in most 

 fountains, are the syrup compartments. A\'ith this hint a soda wa- 

 ter operator, aided l)v a chemist and ])lumber, can make himself in- 

 dependent of the Ice Trust.
