 except at experiment stations, where it would be desirable to preserve 

 the monthly milk sheets, as the monthly total would show all that any

There are a number of ways in which the monthly totals can be 

 preserved. The regular herd books on the market for this purpose 

 devote two pages to each individual, giving sufficient space for all data 

 In regard to the animal for a number of years. On the first page is a 

 blank form, on which to enter the detailed pedigree of the cow. Below 

 this form is an elaborate scheme for entering the data for breeding, cal- 

 culated date of calving, actual date of calving, sex of calf, and a column 

 to note the final disposition of the calf. On the record page is a num- 

 ber of blank forms, each for one year, and containing separate columns 

 for the monthly yield of milk, monthly fat test, butter fat and estimated 

 yield of butter. These herd books are very nice for one who feels that 

 he can stand the expense; but there is a great deal of space that would 

 not be used for an ordinary dairy herd, and a blank book, containing 

 enough space for alt the necessary data for a number of years could be 

 purchased for fifty cents, at the most. This book could be ruled off to 

 suit the desires of the owner. 



On the following page is given a satisfactory scheme for keeping yearly
