which supply milk for the use of children must not be fed 

 mangels and carrots beyond the extent of one peck per day. 

 Oil cake (rape-seed) may be fed to the extent of but one and 

 one-half pounds per day, and this only in connection with at 

 least five pounds of grain feed. Cows supplying milk for the 

 use of children must not be fed oil cake of any kind. For 

 other cows the grain mixture used shall receive the company's 

 approval before delivery of milk can begin. 



" (2.) In the summer time the cows must not be fed in the barn 

 under any conditions. They must be pastured on clover and 

 grass. Vetches must not be used for their food. When 

 necessary, arrangements may be made with the company for 

 the use of grain or green grain crops during the summer. 



" (3.) The cows must be clipped on the udder, tail, and hind 

 quarters in the fall before they are put in the barn. 



" (4.) The time of calving of cows in the herd must be dis- 

 tributed as evenly as possible through the year, so that the 

 amount of milk delivered, especially during September and 

 October, shall not be less than two-thirds of the greatest 

 amount delivered in any month. 



" (5.) Fresh milk up to twelve days after calving must not be 

 delivered, nor will the company receive milk from cows which 

 give less than six pounds per day. 



" (6.) The utmost cleanliness must be observed in milking, 

 and the milk must be strained through a metal strainer covered 

 with a clean woollen cloth. 



" (7.) There must be at the disposal of the dairy at least thirty 

 pounds of ice for every 100 pounds of milk produced on the 

 farm. 



" (8.) Every dairy must be supplied with a Lawrence milk- 

 cooler. This may be rented from the company if desired. 



" (9.) As soon as the milk is drawn from the cow, it must be 

 cooled by the use of ice water on the milk-cooler, and this at 

 all seasons of the year. This cooling should reduce the tem- 

 perature of the milk to at least 4 Reaumur (41 F. ) before it 

 is shipped.
