there is another cow of that age who will produce that much 

 milk. 



Here is another story that we tell. The dam of Cow No. 24 

 is the daughter of the cow I just spoke of. She was born in the 

 year 1901 or 1902. It was a year that I was selling milk to the 

 cheese factory and I did not have any skim milk. She was born 

 along about May, but instead of feeding much milk I fed whey. 

 It was a very dry summer and that cow was always under sized 

 and never developed to what her dam was, or what her daughter 

 was, and I think that was why she never produced very well. If 

 we want to have good cows, we must keep the heifer calves 

 growing from the day they are born until they mature. It is 

 not only true of heifer calves, but of all stock — a horse or a hog. 

 You get runts unless you keep them growing. Raise your heifer 

 calves from the best cows you have and keep them growing from 

 the day they are born, and you will have a good producing cow. 



Cow No. 36. This shows her first three lactation periods. 

 When she was 2 years old she produced 7,808 pounds of milk 

 and 329 pounds of fat, and when she was 3 years old she pro- 

 duced 7,180 pounds of milk and 293 pounds of butter fat. She 

 was milked until she was nearly fresh again, and while I know 

 when every cow is due to be fresh and I did not think she would 

 come in so soon, one day I found she was nearly due to calve, 

 and we were still milking her. So she practically did not go 

 dry. That was why she did not give so much the second time. I 

 estimated these third figures before the year was up, as it. does 

 not close until the end of March. She produced 447 pounds of 

 fat in her third lactation period and is doing as well this year. 

 The dam was a good cow, but here is her daughter that produced 

 last year more than 100 pounds of fat more than her dam. The 

 increase here will be much larger when we get her a mature cow. 



Cow No. 37 produced 11,018 pounds of milk and 380 

 pounds of fat. I have not a record of that cow's dam, because I 

 bought her, but she was sired by a pure bred sire, and last year 

 that cow produced 443 pounds of butter fat, and she is going to 

 do as well this year. She will produce over 12,000 pounds of 

 milk. She did last year. The first year that we weighed the
