six million fat globules per second, and that a cow gives 8,000 

 pounds of milk in 120 days, as did one of those in the St. Louis 

 dairy tests, in manufacturing milk at the rate of nearly one and 

 one-half quarts per hour, day and night. 



Few investments are accumulating interest at the rate of 

 eight cents per hour as was the case with this cow, if her milk is 

 worth about live cents per quart. 



Another feat accomplished by this cow was the production 

 of 903 lbs. of milk solids in 120 days, or about seven and one- 

 half pounds of solid, digestible food every twenty-four hours. 

 Isn't that a wonderful performance and doesn't it increase your 

 respect for a cow ? 



The cost of the feed of this cow was $36.57, and if the 

 8,000 lbs. of milk made from it is worth five cents per quart its 

 total value is $200. This was produced in four months, or at 

 the rate of $50.00 per month. The feed cost of $36.57 is equal 

 to about $9.00 per month, making a possible net return of nearly 

 $41.00 per month from this cow. 



During the 120 days she gave over eight gallons of milk 

 per day (67.5 lbs.) and this contained two and three-fourths 

 pounds of butter, which is a wonderful record to be kept up for 

 so long a time. The feed cost of this butter was eleven cents 

 per pound ; and of the milk, nine-tenths of a cent per quart. 



This cow ate during the 120 days, 10,347 pounds of feed, 

 of which about one-fourth (2,652 lbs.) was grain or concen- 

 trated, and in addition to her milk production, she gained 54 

 pounds in live weight. 



Another wonderful cow in the World's Fair tests gave 

 5,800 pounds of milk during the 120 days, and it contained 

 within one-third of a pound as much butter as the first cow men- 

 tioned. She ate 6,543 pounds of feed, of which about one-third 

 (2,100 lbs.) was grain. The feed cost of the butter produced 

 by this cow was nine and four-tenths cents per pound, and that 

 of her milk was one and one-tenth cents per quart. She made 

 practically the same amount of butter as the first cow, but ate
