THE GUERNSEY 401 



yields of fat from 703 to 773 pounds each. With the present im- 

 proved condition of the breed it is not unreasonable to expect the 

 average herd to produce 350 pounds of butter per head, if not more. 



The cheese value of Guernsey milk ranks very well, although 

 not largely used for this purpose, being mainly turned to butter 

 production or retail milk trade. The milk stands well in total 

 solids, that of whole herds often averaging 14 to 15 per cent, 

 thus furnishing a satisfactory grade of cheese. The only official 

 test on a large scale showing the value of Guernsey milk in 

 cheese-making was in 1893 at the World's Columbian Exposition. 

 I ft this trial, covering fifteen days, participated in by Guernseys, 

 Jerseys, and Shorthorns, the Jerseys stood first, scoring 90.7 ; the 

 Shorthorns, second, scoring 90.5 ; and the Guernseys third with 

 87.2. However, in net profit the Guernseys stood second to 

 the Jerseys. 



Families of Guernsey cattle have attracted attention only in 

 comparatively recent years and more especially since official 

 testing has become established. The number of families is not 

 large, but of these the following may be regarded as of special 

 distinction. Charles L. Hill has made a valuable contribution 

 regarding Guernsey families, 1 and from his writings the author 

 quotes freely and with appreciation. 



The Bonnie Lassie family descends from Bonnie Lassie of 

 Fernwood 1845 A. G. C. C., calved on Guernsey in 1883 and 

 imported to Boston in September the same year by L. W. Ledyard. 

 Her first calf, Bonny Boy 1097, did much for the fame of this 

 family. He sired several excellent daughters, but his real impor- 

 tance is through his sons, of which Lily's Bonny Boy 2676 is 

 especially noteworthy. He was sire of Lily Ella 7240, with a 

 semiofficial record of 782 pounds of fat in a year, and of Lilly ita 

 7241, with a record of 71 1 pounds. Three of his other daughters 

 have official records of over 500 pounds of fat each, and twenty- 

 eight of his daughters have private or public records exceeding 

 Advanced Registry requirements. The great record cow Murne 

 Cowan 19597 is a granddaughter of a son of Lily Ella -Lily 

 Ella's Jeweler 5417. The blood of this and the Materna families 

 have been much intermingled.
