276 ILLINOIS STATE DAIRYMEN'S ASSOCIATION. 



The owner is expected to furnish a Babcock tester, acid, 

 and composite sample jars (fruit jars), and to care for the Sta- 

 tion representative from the time he arrives at the nearest rail- 

 road station until he returns to the same. The Station furnishes 

 other necessary apparatus. 



The representative shall identify each cow by use of the cer- 

 tificate of registration which the owner must provide. If the 

 color markings do not correspond to those on the certificate, 

 or if the certificate is wanting, the representative must sketch 

 carefully, on a blank provided, the markings of the animal and 

 attach the same to the record. Such records will not be accepted 

 until the proper certificates are produced. 



The representative shall see that each cow is milked dry 

 and that the time is recorded at the last regular milking previous 

 to the beginning of the test. He shall also see that the test 

 doses at exactly the same time of day at which it began. 



The milk from each milking shall be weighed, sampled and 

 tested by the representative, and all samples shall be kept under 

 lock and key until tested and recorded in duplicate. 



In case of semi-official tests lactometer and temperature 

 readings should always be taken. For this purpose the milk 

 should be cooled below 70 degrees F. and if possible to 60 de- 

 grees F. 



Not more than one cow shall be milked at the same time, 

 and the milker, while milking, shall constantly be under the 

 observation of the representative. 



The record blank should be filled out and signed before a 

 notary public as soon as the test is completed, and sent at once 

 to the Station for approval. 



A composite sample consisting of a proportionate part of 

 each milking shall be taken and sent to the Station at the 

 close of the test. 



In semi-official tests a careful statement of the feed shall be 

 procured and recorded. 



The results of seven or thirty-day Holstein-Friesian, and 

 two-day Guernsey tests shall be reported, immediately on com-
