The milk of these cows went with that of the others in making up 

 the results given in Table II, but on one day of each alternate 

 week a sample of the milk of each of these cows was taken and 

 analyzed separately. In the following table the average results 

 for the three periods for the single thin cows is shown in compar- 

 ison with the results for the whole lot, as given in table II. 



It will be seen that not only did the thin cow fed on pasture 

 and grain not yield more milk and butter than her companion 

 that had nothing but grass, but in fact yielded considerably less. 

 At the time that the selection was made it was thought that the 

 former would in all probability be most likely to be favorably affect- 

 ed by the grain ration. She was the younger, rather the thinner, 

 and seemed to have rather more vitality. For these reasons she 

 was selected to receive the grain ration. She failed entirely to 

 respond to the grain feed in milk and butter, but did gain consid- 

 erably more in weight, as will be seen when we come to make a 

 study of the changes in live weight.
