The Grimm, Caucasus, Western Grown, and Canadian varieties 

 gave the largest yields. The Grimm alfalfa started early in the 

 spring and was ready to cut before any of the other varieties. 



MILLET. 



Four varieties of millet were grown, namely, the Jai^anese, Colo- 

 rado Golden, Hog, and Xew Siberian. Of these the Japanese 

 jdelded the greatest amount of hay, but the Colorado Golden was 

 the earliest and set a large quantity of heavy, plump seeds. The 

 Colorado Golden promises to be valuable on account of its short 

 season and high seed j^roduction. Further tests will be made with 

 it for the purpose of ascertaining its seed yield per acre. 



riEIJ) CORN. 



A number of varieties of field corn have been tried for several 

 years without obtaining at any time sufficiently large yields to indi- 

 cate that corn will be a commercially profitable crop in this section, 

 except possibly in the most fertile soils of the old river bottoms. 

 During some years the early dent varieties have a sufficiently long 

 period to mature, but it is probable that for the average season some 

 of the flint varieties will give the highest yields. The Australian 

 White Flint was the earliest and best yielding variety tried in 1912. 



HORTICULTURAL WORK. 



There are two small orchards on the experiment farm. One of 

 these came into bearing for the first time in 1912. Observations have 

 been made on the bearing orchards on some of the older ranches of 

 the project during the past three years. Identifications have been 

 made of many of the varieties and notes as to their relative ])roduc- 

 tivity have been taken. A few of these old orchards have been
