1915.] PUBLIC DOCUMENT — No. 31. 53 a 



outbreak of foot and mouth disease interfered seriously with the 

 work. From Dec. 1, 1013, to Dec. 1, 1914, 110 Guernsey, 112 

 Jersey, 23 Ayrshire and a few Holstein yearly tests were com- 

 pleted. Owing to the disorganized state of the work on De- 

 cember 1, on account of the foot and mouth disease, it is im- 

 possible to give with any accuracy the number of cows on test 

 at that time. For the Holstcin-Friesian Association there have 

 been completed 189 seven-day tests, 5 fourteen-day tests, G 

 thirty-day tests, 2 sixty-day tests and 1 sixty-nine day test, the 

 latter being in connection with so-called semi-official work.
