3- The owner of each herd desiring tests must provide a satis- 

 factory Babcock machine, the necessary acid and hot water, and a 

 suitable box or cupboard fitted with a hasp for a padlock, in which 

 the supervisor may keep his samples. 



4. Only cows which are entered in the herdbook of the breed to 

 which they belong are eligible to advanced registry. 



5. In case of long tests, supervisors will be changed every thirty 

 days, if deemed advisable. 



6. All reports of tests must be brought or sent to the Experiment 

 Station by the supervisors. Such reports, after being verified, en- 

 dorsed and copied, will be forwarded to the proper club. The sta- 

 tion, however, reserves the right of using the data, if deemed advisa- 

 ble. 



DUTIES OF THE SUPERVISOR. 



1. The supervisor shall not be held responsible for the identity 

 of any cow tested, but shall accept the statement of the owner or 

 his representative as to her name and registration number. The 

 supervisor, however, shall state whether the cow answers her regis- 

 tered description, if the same has been furnished him ; otherwise, he 

 will include in his report a brief description or sketch of each new 

 animal tested. 



2. The supervisor shall see the cow milked dry at the regular 

 milking prior to beginning the test,* shall verify the fact with his 

 own hands and note the time of the same. The last milking must 

 occur at the same hour, one or more days later according to the 

 length of the test. 



3. The number of cows to which an inspector is limited shall be 

 dependent upon the amount of work required and the facilities at 

 hand. He shall not exceed five cows when milked four times daily, 

 without special permission from the station. He shall allow only 

 one of the cows entered to be milked at a time and shall personally 

 oversee the entire milking. 



• In case of Ayshires it is not necessary to see the cow milked dry before beginning 

 test.
