the average for foreign wheat. All three of the varieties grown 
with the application of nitrates are well above the average, in 
fact, are very good indeed. If the reader will turn back to the 
table of general samples of winter wheat he will observe that only 
three of the 19 samples are much below the average for domestic 
wheats, while nine are much above it. 
COMPARISON OF COLORADO AND MINNESOTA 
WHEATS 
Of course the question which has been at the basis of all of 
this work is simply. What makes this difference? The general 
impression is that all of our wheat, when compared with Minne¬ 
sota wheat for instance, is inferior in composition, that is, contains 
less gluten. This is not true, a great deal of our wheat is just 
as good and even better than Minnesota wheat. In 16 analyses 
of Minnesota wheats which I find in one of their bulletins the 
crude protein varies from 11.63 to 16.02 percent, and in 28 analyses 
that I find in another bulletin the crude protein in the wheat, 
which is about 1 percent more than is found in the flour, ranges 
from 11.17 to 15.75 percent. In some samples that I obtained from 
Minneapolis as samples of wheat which was on that market, marked 
Minnesota Spring No. 1, 2 and 3, I found :

These 
samples were not as fine 
looking wheats 
as our own 
products and the analyses are just about average. 
One thing to notice in these results is that they are more 
uniform than ours but the number of samples is smaller. We have 
some very low ones, our Red Chaff from Eckert carried only 8.04 
percent crude protein and the Defiance sample from Del Norte 
8.05 percent, whereas the Fultz from Fort Collins carried 16.33, 
and another sample of Red Fife 17.14 percent crude protein. These 
differences are very big though these samples were grown in good 
seasons, so that we cannot blame the weather, nor can we blame 
much of the difference to the variety, for while the Defiance is 
a soft wheat it is not always a poor wheat. This difference in the 
value of samples cannot but hurt the reputation and perhaps the 
market price of our whole crop. We can obviate this in so far 
as it is due to the land. We can, in the first place, plant varieties 
with a high protein content. The Marquis, for instance is, with
