A Study of Colorado Wheat

tion in the moisture, ash, fat, and crude fiber is too small to play any 
important part in our present discussion. We shall give the ash con¬ 
stituents to show how little they vary in the three seasons, although 
the wheats are of very different composition. We shall confine these 
to the check plots of a single section to avoid, as far as possible, vary¬ 
ing conditions and confusion due to different fertilization, and also for 
the further reason that we have determined the ash constituents in the 
kernels of one section only. The series of checks given in the following 
table runs north and south through our land; had it been taken east 
and west, the individual data would have been different, a fact which 
we do not wish to evade; but the general results would have been the 
same, so far as the data actually acquired may be depended on to show:
