good, but the bulls at maturity are liable to be nervous and 

 are often cross. Jerseys mature very young, compared with 

 other breeds. 



The milk of the Jersey is usually yellow in color and 

 rich in butter-fat. The skin of these cattle show something 

 of this rich yellow color, especially in the small, wax-col- 

 ored horns, in the ears, and about the udder. The Jersey 

 of good breeding produces a fair amount of milk, and 5,000 

 pounds a year may be regarded as common, while many 

 cows have produced over 10,000 poimds a year each. Up 

 to May, 1921, over 1,500 two-j'ear-old heifer records of Jer- 

 seys average 7,691 pounds of milk, while 1,459 cows five 

 years old or over show an average of 9,701 pounds of milk. 

 The cow of this breed showing the most remarkable pro- 

 duction is Sophie 19th, of Hood Farm, that during nine 

 consecutive years produced 110,938 pounds of milk. The 

 heaviest milk record of a Jersey cow in a year was 19,694 

 pounds by the cow Passport. Jersey milk usually contains 

 4i}/2 to 5 per cent of fat, and makes a high grade of butter. 

 Many cows have produced enough milk in a week to yield 

 14 or more pounds of butter. Some few have records of 

 over 20 pounds in a week. Many Jerseys have produced 

 enough milk within a j^ear to yield 500 pounds of butter, 

 and some have even exceeded this. Up to May 1, 1921, the 

 1,543 two-year-olds noted above gave an average annual fat 

 yield in the milk of 356 pounds, while the 1,459 aged cows 

 averaged 510 pounds of fat. Up to 1921 three Jersey cows 

 have produced 1,000 pounds or more of milk fat in a year. 

 Plain Mary having 1,040 pounds and Vive La France 1,039 

 pounds, and Sophie's Agnes 1,000 pounds. In nine con- 

 secutive yearly records, Sophie 19th, of Hood Farm, pro- 

 duced a total of 6,354.6 pounds of milk fat. 



There is a number of noted Jersey families, of which the 

 Golden Lad, Oxford, Financial Interest, Signal, St. Lambert, 

 Coomassie, Eurotas, Tormentor, and Owl-Interest are cspe-
