BUTTER. 51 



ounces of butter from 20 quarts of milk, a propor- 

 tion of 1 to 11 1 2 ^ pounds. In the same volume is a 

 statement of a proportion of 1 to 17^ pounds. 



Mr. F. H. Appleton writes that his cow Maud 

 yielded butter in the proportion of 1 to 15 T 6 Q pounds. 



Four experiments carried on at Waushakum Farm, 

 by churning small quantities of milk in a bottle, 

 give a proportion of 1 to 25 to 28. This, however, 

 does not give a true result except as marking a 

 limit, for the trials were not designed to obtain an 

 answer to this question. A portion of excellent 

 Jersey milk, churned about the same time, yielded a 

 proportion of about 1 to 40. From incomplete exper- 

 iments we should place the proportion for a fair herd 

 of Ayrshires at about 1 to 20. 



Mr. Colman, 13 while travelling through Scotland, 

 was told by a farmer in Stirlingshire of the highest 

 eminence that his Ayrshire cows, in the best of the 

 season, averaged one pound of butter per day, and 

 that he had known two Ayrshire cows to make 2 

 pounds 2 ounces each per day. 



Mr. Caird 14 speaks of these cattle being kept in 

 Norfolk County, England, for the purpose of making 

 butter for the London market. 



Mr. Robert Wilson, of Kilbarchau, writes us that 

 he had owned a cow that gave 2 pounds 6 ounces 

 daily, or 16 pounds weekly; and another that did 

 the same on two trials in two successive years.
