9. Stella. 



This cow was large, squarely built, evidently of Short Horn descent, 

 though she^ was naturally polled and was^said to have some Red 

 Polled blood. She was dark roan almost red in color, and had a 

 tendency to take on jBesh rapidly under good feed. She had been 

 suckling calves for about 10 weeks when her records began on May 

 16th. Her lactation periods w^ere as follows: 



1900 from May 16 to Dec. 7 29 weeks 



1901 Dropped calf March 26, dry Dec. 15 38 weeks 



1902 Dropped calf May 3, dry Jan. 1. 1903 34 weeks 



1903 Dropped calf March 15, dry Nov. 10 34 weeks 



10. Tilda. 

 The cow Tilda was medium sized, showing some Short Horn blood. 

 She .was an excellent milker and had comparatively little tendency 

 to take on flesh, though she was the heaviest feeder of any. At the 

 beginning of the experiment she had been suckling calves for some 

 time, at least for three months and probably longer. She was bred 

 to calve again in^ December, 1900, so that her record for the first 

 period includes only the latter half of a lactation period. She was 

 milked more in the winter than any of the other cows, as the record 

 of her lactation periods will show: 



1900 



1901 Dropped calf 



1902 Dropped calf 



1903 Dropped calf 



1904 Dropped calf 



from May 16 to Sept. 25 19 weeks 



Nov. 29, 1900, dry Nov. 1, 1901 48 weeks 



Feb. 12, dry Oct. 25 36 weeks 



Jan. 10, dry Oct. 10 . 36 weeks 



Dec. 4, 1903, to close of expt. Feb. 23, 1904 11 weeks 



When the cows were returned to Mr. Gibson on February 23, 1903, 

 this cow had been milked for six weeks in the fourth lactation. She 

 calved again December 4, 1903, and was in milk at the close of the 

 experiment. In making up her record for the fourth period we have 

 included the product from February 23, 1903, to February 23, 1904, 

 or 44 weeks, excluding the time she was dry, since this represents 

 the product while she was under Mr. Gibson's treatment even though 

 it is not all included in one lactation period.
