The operator stands on the opposite side of the tank and revolves 

 the crank with his foot. Tank holding about seventy quart bottles 

 and cleaner complete cost only $10. After cleaning the bottles the 

 same way as the cans, the latter must be placed in a boiler large 

 enough so that they are all submerged in the water. The water 

 should only be lukewarm when the bottles are put in and then be 



brought to a brisk boiling and kept 

 there for ten minutes. When the 

 water is cooled down to 160 take 

 out the bottles and place them bot- 

 tom up in the racks. 



, I If the bottles are taken imme- 



.1 >fc diately out of the boiling water 



and the air is rather cold, there 

 will be more breakage. 



While it may be possible to 

 keep bottles clean with water, there 

 is hardly any reason why every 

 farmer with ten or more cows 

 should not have a so-called feed 

 cooker so as to produce steam, even 

 at a low pressure, and thus have 

 the means of properly cleaning his 

 cans and dairy utensils. They are 

 sold cheap enough, varying from 

 Fig. 62 . $35 to $75. and are as a rule, built 



in America, like a vertical boiler, Fig. 62
