DEMAND FOR HARVEST LABOR IN THE WHEAT BELT. iii 
per 100 acres cut does not seem to differ materially in areas where 
the binder predominates from the amounts used where the header is 
commonly used, and (2) that there seems to be a striking variation 
in the amounts of labor used in different areas using the same 
machinery. 
The relative effects of the header and the binder upon the demand 
for harvest hands is not fully apparent, however, until the data in 
Tables I and II of the appendix are correlated, and this can best be 
done by comparing the facts for North Dakota, an area in which the 
binder is used exclusively, with Kansas, where the header pre- 
dominates. Table I of the appendix shows that the average sizes 
of the farms visited in the two States were approximately the same. 
Table IL of the appendix indicates that 85 per cent of the cultivated 
acreage of the Kansas farms was in small grain and 78 per cent of 
the North Dakota acreage. In reality the North Dakota percentage 
was larger since a considerable barley acreage in North Dakota is 
not included in the small grain figures given in Table II of the ap- 
Fic. 3—Header with stacker-barge, western Kansas. This barge is so constructed that when loaded it 
can be opened and drawn from under its load, leaving a stack of grain 
pendix. Table I shows that in Kansas the amount of family labor 
working in the harvest was 4.6 per cent larger and the number of 
day hands (harvest hands) was 14.1 per cent larger than in North 
Dakota. In Dakota the percentage of month hands exceeded 
Kansas by 18.7 per cent, balancing the excess of family labor and 
day hands in Kansas. In other words, the percentage of hired 
labor working in the harvest was 4.6 per cent larger in North Dakota 
but the percentage of harvest hands employed was 14.1 per cent 
smaller. It appears, therefore, that while Kansas uses. but slightly 
more labor per 100 acres of grain harvested, it hires a larger percentage 
of that labor during the harvest season and solely for harvest work. 
Consequently Kansas develops a more intense demand for harvest 
hands, in proportion to acreage harvested, than North Dakota does. 
Is the difference in machinery used the explanation for this more 
intense demand for harvest hands ?
