because of her imperfect udder she was dried off and sold in Septem- 

 ber, 1901. Her lactation periods were as follows: 



1900 



1901 Dropped calf 



March 28 to Nov. 20 

 Jan. 12, dry Sept. 7

 33 weeks 



2. Clover. 



Clover was a grade Jersey cow of good form and fair size. She 

 was the oldest cow in the herd, and when the cows were brought to 

 the university she was so thin in flesh that it was doubtful whether 

 she would survive the winter. She did survive, however, and pro- 

 duced a calf, but she gained very little in flesh and no attempt was 

 made to breed her again. (Figs. 1 and 2, p. 20, 21.) When the experi- 

 ment began she had been in milk about four weeks. 



Her lactation periods were as follows: 



1900 March 28 to K^ov. 20 34 weeks 



1901 Dropped calf March 3, dry Feb. 1, 1902 47 weeks 



3. Dena. 



She was a small black cow of inferior shape, with perhaps a trace 

 of Jersey blood. She had a poorly shaped udder and badly placed 

 teats. However, she proved to be an excellent producer. She was 

 suckling a calf when the experiment^began and had been fresh for 

 about a month. Her lactation periods were as follows: 



1900 



1901 Dropped calf 



1902 Dropped calf 



1903 Dropped calf 



April 4 to Jan. 1, 1901 . 39 weeks

Dec. 28 to close of expt. Feb. 23, 1904 8 weeks
