I he work on the soils from our standpoint is quite un¬ 
satisfactory, but either someone else or ourselves may be 
able to make a systematic study of this subject which is of 
some importance as well as of interest to the West. 
The soil in which the Weld county samples were grow¬ 
ing was sampled to the depth of eleven and one-half feet in 
three parts, corresponding to the large variations in the 
character of the soil; at the same time a sample of soil was 
taken a few feet distant from a field planted to corn, but 
owing to lack of water it was practically fallow at the time. 
The corn plants had made no growth during the season ; 
subsequently a fifth sample was taken of the blown soil 
which gathers about the large crowns of alfalfa containing 
a great many leaves and plant refuse. This enables us to 
present the composition of the plant, the root, the soil ac¬ 
cumulation about its crown, the soil proper, the subsoil in 
two sections, and that of a sample of the soil not in alfalfa. 
The alfalfa was six years old. The plants were very large, 
some of the stems being over five and one-quarter feet high, 
and the largest of the roots one and one-half inches in di¬ 
ameter, with abnormal roots, i. e., such as had short tap 
roots two to three feet long attaining a diameter of two and
