milk yield multiplied by seven, and in that of "Pounds Butter 

 Fat" the result multiplied by the percentage of fat and divided 

 by 100. To calculate butter yield add one-sixth to the butter fat.

In testing cows they should be milked at exactly the same 

 hour in the evening on the test day as on the day before. The 

 total milk should be weighed or measured daily in order to con- 

 trol the production, and so should that used in the house or for 

 the calves. The last pointer I desire to give in this chapter is to 

 suggest either the offering of premiums, as Mr. Gurler does, to 

 those milkers (be they hired men or your own boys and girls) 

 whose cows keep up the milk flow best, or making them co-part- 

 ners by giving them a certain share in whatever the cows yield 

 during the year over a certain amount. If you do this and let 

 the milking be counted as work and not as a little extra "chore" to 

 be done after dark (sooner or later, as the field work may allow), 

 you will find the cows will respond and the cost of production will 

 be reduced.
