more than 11 percent belong to the higher grades of wheat. This 
is the principal thing that an analysis of wheat shows, so far as 
the farmer is concerned. This, however, is just what, in the next 
place, we want to show the Colorado farmer about our wheats, 
and to show him further how he can grow better wheat, and wheat 
which is more uniform in quality than we are growing. 
First, however, we shall give him some idea of how our wheats 
vary in quality, and, as we have shown why we use the amount of 
crude protein in wheat as the measure of its quality and that the 
other details of the composition of wheat are not material for the 
farmer’s understanding of the question with which he has to deal, 
we shall give only the crude protein, wet and dry gluten. While 
the ash and other constituents may be important from certain 
points of consideration, they do not play any big part in the 
questions interesting the wheat grower, and, besides, they will 
largely take care of themselves under our Colorado conditions. 
The only object in giving wet gluten and dry gluten is to show 
how much water the wheat proteids take up. Gluten washed out, 
as these glutens were, always contains some starch and other 
things, but we will not go further into these details.
