THE PASTEURIZATION OF MILK 



The drivers of retail delivery wagons who han-

 livering milk grasp the bottles by the neck, are 

 particularly likely to leave some dirt or contami- 

 nating material upon the lips of the bottles over 

 which the milk will be poured. Serious infection 

 may result. Caps which are real seals and which 

 at the same time protect the neck and lips are on 

 the market, but are rather expensive. They are 

 used by dealers upon special grades of milk, such 

 as Certified, Grade A, etc., but are as yet too costly 

 to be used upon the lower or common grade of 

 market milk. A great many attempts have been 

 made to devise a safe seal which shall be protec- 

 tive and shall be inexpensive, but none have been 

 very successful. A fortune awaits the man who 

 can produce a satisfactory seal of this character.
