calving. For the purpose of investigating this question we 
have gone over the milk records of the Waushakum farm 
herd, South Framingham, Mass., as kept by the Sturtevant 
Bros., from December, 1866, to December, 1881, inclusive, 
and have arranged the milk yields of each cow for each 
thirty days from calving. These records are: 
For 35 different native cows, and 59 calvings, 
For 45 different Ayrshire cows, and 145 calvings. 
For 3 different Jersey cows, and 6 calvings. 
While the natives were kept, the feeding was liberal, 
yield being the objective point, regardless of the calves. 
While the Ayrshire cows were maintained, the feeding was 
lower, as befitted a breeding herd, and the records embrace. 
the yield of many young animals in their first year of milk. 
For the whole herd, during the fifteen years, the calvings 
were quite well distributed over the year, no particular 
season for calving being desired, as the milk was disposed 
of at retail during much of the time. eid nai 
We give a table of our results under two heads; the first 
embraces every cow, farrows as well as those in regular 
calvings, and cows which only remained a few months in 
the herd. The second embraces only those cows which 
went dry between the eighth and twelfth month from 
calving.
