are pumped over and over again with great force against 

 the bottles, both inside and outside. The water in the 

 tanks is renewed automatically and continuously, a small 

 stream of water coming in and a small stream of impure 

 water running out. 



The Milk Bottle. The only style of milk bottle used 

 to any extent at the present time is that made of glass. 

 The advantages of a glass bottle are as follows: 



1. It is easily cleaned and sterilized. 



2. The consumer can easily detect the presence of 



dirt of any kind in the bottle or the milk. 



3. It cannot itself impart any flavor to the milk, 



and forms a perfectly tight package to keep out all 

 dirt, flavors, etc. 



4. It cannot corrode nor become unsanitary in any 



way, however old it may become. 



The disadvantages of a glass bottle are: 



1. It is fragile. 



2. It is costly. 



3. It is heavy. 



4. Unless sterilized before being filled it may become 



a carrier of disease. 



Because of these disadvantages, numerous attempts 

 have been made to introduce a single-service container 

 made of paraffined paper. This seems to be the only 

 alternative to glass, all metals being out of the question. 

 But the consumer cannot see the thickness of the layer 

 of cream on the top, he cannot tell whether the milk in 

 the paper container is clean or not, and the package is 

 not so pleasing to the eye. These are the chief reasons 

 for the failure of the single-service container to be gen- 

 erally adopted.
