than the Jerseys. They have coarser bones and 

 carry more flesh. Guernseys are noted for their 

 yellow milk, which is only second to that of the 

 Jersey in richness. But they often give a greater 

 amount than the Jersey. 



The Holstein. This dairy animal was bred 2,000 

 years ago along the Ehine, in Europe. The Dutch 

 first brought these cows to America, shortly after 

 the settlement of New Amsterdam. The Holstein 

 (Figs. 14 and 107) is noted for the great amount of 

 milk given. ^ The milk is not so rich in butter-fat 

 as that of the Jersey or Guernsey, but the large 

 amount makes her a most desirable cow to keep 

 near large cities like New York, where the milk is 

 sold by measure. Other noted dairy types are the 

 Ayrshire, the Brown Swiss (Fig. 15), and the Dutch 

 Belted. 



The Babcock Milk Test. For a long time dairy- 

 men did not know how to choose the cows which 

 gave the richest milk. Not many years ago Dr. 

 S. M. Babcock, of Wisconsin, invented a machine 

 to test milk for the amount of butter-fat. Now 

 every farmer may know which cows are valuable 

 and which ones are not. Eefer to page 247 for full 

 descrijjtion of the Babcock Milk Test. 



What a Good Cow Produces. A good cow should 

 produce from twelve to fifteen pounds of butter a 

 week. One of the highest records ever made was 

 by a Holstein cow that made thirty-three pounds 

 of butter in one week (Fig. 14).
