54 BULLETIN 1296, U. S. DEPARTMENT OF AGRICULTURE 
Variations in the amount of manure and straw hauled on different 
farms are due principally to differences in the numbers of livestock 
kept and to different quantities of straw hauled for the protection of 
the wheat. A large portion of the hauling on farms 17, 11, 6, and 2 
was of straw. Manure and straw hauling constitute less than 4 per 
cent of the total field labor shown in Table 29. This labor can 
easily be done without interfering with seasonal crop labor. 
MISCELLANEOUS CROP LABOR 
Labor requirements for crops shown in the preceding tables in- 
clude only the labor involved in performing the field operations on 
these crops. They do not include labor expended in cleaning or 
treating seed, purchases of seed, or materials required, or any market- 
ing work except that shown in Table 8. The marketing of wheat is 
the most important item in this class of labor. The "other crop 
labor" requirements are shown in Tables 29 and 30. 
MISCELLANEOUS LIVESTOCK LABOR 
In addition to the regular daily chore labor of feeding, milking, 
bedding livestock, and cleaning barns, considerable work is done on 
the livestock at irregular intervals. Such special labor as hauling 
feed, caring for sick animals, buying and selling stock, and other 
tasks performed at irregular intervals, constitute from 4 to 35 per 
cent of the total labor on livestock. The average quantity on the 
farms studied was about 15 per cent of the total man labor. Some 
of this labor, such as hauling feed, several classes of stock bear 
jointly. The horse work for these special tasks was greater than 
that for the regular chore work on most of the farms. On those 
farms where considerable feeding was done and feeds hauled out 
with a team daily the chore work done by horses was greater than the 
special work. The total hours of man labor spent at chores and at 
special work on livestock are shown in Table 29 and the total amount 
of horse work in Table 30.
