1 Three bought and seven 2-year-olds dropped back: from the 1907 group. 
2 One died. 
3 One butchered. 
Of the calves included in this record, 86 were selected at birth. 
28 yearlings from 1907 were on hand on September 1, 1908, when 
the records were started, and 3 were purchased, making a total of 
117 calves for the five years. Out of the 86 selected. 18 were dropped 
out before they were 1 year old. Eleven of these were pure-bred 
bulls. Any of these bulls that were not sold before the age of 6 
months were separated from the heifers in the feeding pen, and 
after June 1 a separate record was kept of them. Of the 7 heifers, 
1 died and the other 6 were discarded and sold. 
Including the 3 yearlings that were purchased and the 28 in the 
1907 group, there were 99 of the 117 to enter the second record year. 
Of these' 99, the 1911 group of 17 dropped out because records are 
not yet available, 3 bulls of the 1907 group were sold, 5 discarded 
heifers were sold, and 1 died. Thus, of the 117 calves, 73 heifers 
were raised during the five years. 
By means of Tables II to VII, inclusive, the problem of the cost 
of production is illustrated by complete records of one group of 
calves from birth in September. 1909, up to the time they entered 
the herd at 2 years of age in September, 1911. The quantity of each 
feed consumed was obtained by actual weighing, the prices shown 
in Tables III and VI being the local prices of feeds at the farm, as 
reported at the end of each month. This gives a more accurate feed 
cost than would be obtained by the use of a yearly average price, as 
several of the more expensive feeds vary in price from month to 
month. 
The labor shown in these tables represents the actual number of 
hours of man labor and horse labor expended in caring for the calves 
and has been obtained from the daily labor-report sheets of all 
workmen on the farm. 
The cost rate for man labor is 12 cents per hour for the period 
covered by the records herein presented. The man rate is obtained
