that the weight of the can will be well balanced and each wire will 



fall between two coils of the radiator. 



Bend two No. 15 galvanized iron wires, or a strip of galvanized 



iron 1| inches wide, as indicated in Figure 16, BB. These should 



be long enough to 

 have the ends se- 

 curely soldered to 

 the narrow sides of 

 the can and to ex- 

 tend at least 6 

 inches above the 

 mouth of the can. 



Fill the can with 

 water. Over the 

 rack (BB) hang a 

 double thickness 

 of canton flannel, 

 rough side out, with 

 the ends of the cloth 

 extending down into 

 the water to the 

 bottom of the can. 

 Suspend the can by 

 the curved wires to 

 the rear of the radi- 

 ator. The canton 

 flannel will absorb 

 the water from the

 rapid evaporation from the cloth wicking as well as from the 

 surface of the water in the can. Be sure to keep the can sup- 

 plied constantly with water. It will probably need attention at 

 least once a day.
