milk from each of them, every seventh week, we furnish hint the neces- 

 sary apparatus for doing the work. The outfit consists of a pair of spring 

 scales, milk sheet, sample bottles and tablets for preserving composite 

 samples of milk. The party who undertaker; this work is expected every 

 seventh week to weigh and sample accurately each mess of m ! 'k from 

 each cow in the herd for fourteen consecutive milkings. When the 

 weighing and sampling of the milk are completed, I visit his place and test 

 the composite samples. I am able, with the weights and tests, to determ- 

 ine the amount of milk and butter fat that each cow produces during the 

 week her milk is weighed and sam pled. I estimate from these weights 

 and tests the amount of milk and butter fat she has produced three 

 weeks before the period of weighing and testing, and three weeks follow- 

 ing. 



I have some farmers who are keeping approximate account of the am- 

 ount and kind of feed fed to their cows. This makes the record much 

 more complete, and .my report will be of more value. The accounting for 

 the kind and the amount of feed is not demanded of the person who ac- 

 cepts this work, but we are more than anxious to have them do it. The 

 part of the work that we ask the farmer to perform, is to weigh and sam- 

 ple the milk from each cow every seventh week and to carry me to and 

 from the station, for doing their testing. He has no expense, and only a 

 little labor, to have a complete record of every cow in his herd. 



This record tells him how much milk and butter fat each cow in his 

 herd has produced during the year and when feed is weighed it will give 

 him how much she has consumed to produce this milk and butter fat. Or, 

 in other words, what she has charged him for her keeping. The time re- 

 quired for doing this work depends on the number of cows in the herd. 

 With ten cows, it requires about ten minutes more time each day to do 

 the milking, about seventy minutes every seventh week, or about eight 

 hours per year to do all the extra work. These few hours of time spent 

 give him a record of each cow in his herd. 



It is my duty to keep all the records of the cows that I am testing, and 

 to report to the owner at the end of the year what each cow has done.
