This cow calved again January, 191 1, and started on an- 

 other year of good work, but changed hands and the test was 

 discontinued. The first two years of the above record were not 

 strictly semi-official, but the tests were conducted by the Station 

 the same as the tests on other herds in the state; the milk was 

 weighed and tested for one week out of each seven, and the 

 record was then estimated from this.
