For comparison, I selected a cow of my own, which calved 

 about the 8th of October, and gave soon after 18 quarts of milk 

 per day; she was also of small size. At the time of calving, her 

 condition was somewhat higher than that of Mr. Smith's. When 

 the experiment was begun, on the first of January, no perceivable 

 difference v/as found in the yield of milk of Mr. Smith's cow and 

 my own, each giving 15 J quarts per day. 



The following Table gives the dates of calving of the three 

 cows, together with their weights and }ield of milk at the com- 

 -nencement and termination of the experiment : —

Mr. Smitli's cow lost in w^eight in nine weeks 84 lbs., being 9^ 

 lbs. per week, with an average yield of 12 J quarts per day. Mr. 

 Pawson's lust 28 lbs. : this loss, together with the diminished yield 

 of milk, occurred almost whollv after tlie oats had been with- 

 drawn. Her weight on the 6th of February being still 7 cwt. 2

My cow has gained, in the nine weeks, 56 lbs., being 6\ lbs.

 ing regular. January 1st, 15^; Feb. 4th, 14; March 4th, 12 J;

 up their consumption of food and their bulk.
