28 How to Make Creamery Butter on the Farm 



One of the several styles of 

 Babcock Testers sold by the 

 Minnetonna Company. The 

 hand-operated testers are also 

 made for 4 bottles. Electric- 

 operated testers made for 2 

 to 12 bottles. See Dairy Sup- 

 ply catalog of the Minnetonna 

 Company. 



The most valuable use of the Babcock Test is in 

 showing what each cow in your herd is doing in the 

 way of butterfat production. With this knowledge 

 you can weed out the poor cows and breed the best 

 ones to produce even better butterfat producers. The 

 value of a Babcock Test outfit to the dairy farmer can- 

 not be overestimated. To many farmers it has proven 

 itself worth thousands of dollars. 



Assistant Secretary of Agriculture Vrooman esti- 

 mates that the American farmer would be $10,000,000 

 richer at the end of the year if he took advantage of 

 the knowledge at present on tap in the Department of 

 Agriculture. That estimate is ridiculously low. The 

 owners of the dairy cows alone could make up the 

 $10,000,000 without half trying. Ten minutes a day 

 spent in the study of economical feeds and rations 

 would do the trick. Investment of a few dollars in a 

 Babcock Tester would soon cut out enough of the rob- 

 bers to give the former cow slave an hour a day for 

 studying the problems of profit-getting and home im- 

 provement.
