there is a small groove; after the bottle is filled, it is 

 closed with a para£5iied pulpboard cap which is pressed 

 down into the neck of the bottle by means of a stamp, 

 with its edges in the groove ; at the same time, the cap 

 is marked, and it cannot be taken out without being torn. 

 A similar cover, a pasteboard cap which is pressed a 

 little way into the bottle (without the groove), is used by 

 many milk concerns, but this gives little security, as the 

 cap can easily be taken out and a new one substituted. 



[Paper or wood-pulp discs (sterilized) used as stop- 

 pers may be sealed by pouring on top of them a little 

 melted parafifine. This method is used by some dairies 

 that produce certified milk. The customary method, 

 however, among the best dairymen, is to cover the top 

 of the bottle, after it is closed with the usual disc, with 

 a cap of parchment paper, held around the neck of the 

 bottle with a wire, cord or rubber band; or a cap of 

 heavy tin foil is used, which is pressed down around the 

 shoulder at the mouth of the bottle, and this holds its 

 position quite well. Both of these methods have the ad- 

 vantage of thoroughly guarding the mouth of the bottle 

 and the disc that confines the milk. The lip of the bottle, 

 over which the milk must be poured, is prevented from 

 becoming soiled. These methods, however, do not afford 

 such complete protection against tampering with the 

 contents of the package as is furnished by a lead seal. 

 However, if the box in which the bottles of milk are 

 shipped from the farm to the distributing point, or to 

 the customer, is sealed with a lead seal, as is done by 

 some producers, the protection is sufficient. 



The usual practice among average dairymen is to 

 depend on unparaffined and unsterilized wood-pulp discs, 

 upon which is often printed the name of the dealer. 



Small dealers (and some large ones as well) some- 

 times indulge in the most vicious and unsanitary prac-
