mst than the others. Whether this was due to the stage of develop¬ 
ment or to the characters of the tissues may be a question. We have 
not been able to detect any difference in the date of the ripening of the 
grain due to the nitrate on the one hand or the phosphate on the otlier, 
so the question of development does not press itslf very strongly as ac¬ 
counting for the greater degree in which the nitrate plants were infest¬ 
ed. There is an abnormal ripening in the case of plants grown with 
the application of nitrates, in that the leaves/ and middle parts of the 
plants ripen more slowly than the top and bottom, but we have found 
no difference in the ripening of the grain. 
While these cultural results are of great importance in determining 
the character of the material with which we have to deal, and, un¬ 
fortunately, complicate our question, they are, after all, incidental, even 
though their consideration cannot wholly be set aside. 
THE CHARACTERISTICS OF COLOR.\DO WHEAT 
The first subject that we shall try to consider in regard to Colo¬ 
rado wheat is, whether the composition of the wheat shows anything 
characteristic. 
The wheat grown in the State, even at the present time, is largely 
spring-wheat,.though winter-wheat is being grown in larger quantity 
than formerly. For this reason I shall present analyses of both spring 
and winter-wheats. In regard to the samples sent to me from differ¬ 
ent localities, I can give no details, other than the names and localities 
furnished me. This pertains only to some of the general samples. 
These analyses appear on the pajges immediately following.
