test, and that none of the Guernseys continued after the sec- 

 ond year. 



The table on page 187 gives a complete summary of the 

 work as far as they carried it. 



While the number of individuals involved in this experi- 

 ment is small, the results bear out other similar tests in prov- 

 ing that in economy of butterfat production the Guernsey has 

 no superior. 



In 1900 Prof. F. W. Woll, of the University of Wisconsin, 

 published in tlje Breeders' Gazette a compilation of the aver- 

 age annual production of 186 cows of different breeds, all of 

 which had been at different American experiment stations, 

 and the results are as follows : 



Average Annual Production of Cows of Different Breeds.

It will be noted by this table that not only did Guernseys 

 lead in the average production of butterfat, but also that they 

 produced this at a lower food cost than the cows of any other 

 breed, with the exception of the single Polled Angus cow, 

 with a production much lower than that of the Guernseys. 



The cost of food required for the production of milk and 

 fat was as follows :

In 1893 there was carried on at the World's Fair at Chi- 

 cago a very exhaustive breed test, in which 25 cows of the 

 Jersey, the Guernsey, and the Shorthorn breeds were entered. 

 The test was divided into three periods, the first being from 

 May 16th to May 26th, in which a test for the production of 

 cheese was carried on ; the second of 90 days from June 1st to 

 August 29th, for the production of butter ; and the third of 30 

 days' duration. At each change of period breeders were al-
