This is the best and only reliablemethod, and the one followed at most well regulated dairies. Ofcourse, it takes time, but it pays in the long run. Fairly accurate results may be obtained, however, by weighingand testing one day in each week during the whole period of lacta-tion, multiplying the weight by 7 to get the amount given by eachcow. Another practical method is to take weights and composite. Dolly Bloom. Noted Guernsey cow. Made a record of 17, pounds milk in one year, per cent, yielding pounds butter fat.

This is a seriousmistake, as it teaches next to nothing, and the only way that thedairyman may know exactly what each of his cows is worth to himis by testing frequently, weighing every day in the year and multi-plying the total weight by the average test to get the weight of butterfat.
