DESCRIPTION OF PLATES. 



Plate I. Alfalfa breeding at the Bellefourche Experiment Farm, South Dakota. 

 Fig. 1. — Alfalfa plants in the breeding nursery, showing the first season's growth. 

 The photograph was taken July 29, 1909, three months after planting. The rows 

 are from individual plant selections of the second generation, South Dakota No. 

 167. Fig. 2. — Selected strains of alfalfa in double-cultivated rows (rows 7 inches 

 apart alternating with cultivated space 32 inches wide). 



Plate II. Sorgo at the Highmore substation and the Bellefourche Experiment 

 Farm, South Dakota. Fig. 1. — Sorgo, South Dakota No. 341, at the Highmore 

 substation. South Dakota. The selected strain at the left is ten days earlier than 

 the bulk seed of the same variety at the right. Fig. 2. — Sorgo progeny row No. 

 10, showing uniform type of plants. Grown at the Bellefourche Experiment 

 Farm, South Dakota, in 1909, from seed of a single plant selected in 1908. 



Plate III. Kursk millet at the Bellefourche Experiment Farm, South Dakota. 

 Fig. 1. — Selection rows of Kursk millet at the Bellefourche Experiment Farm, 

 South Dakota. The individual plants are grown in hills 8 inches apart. 

 Fig. 2. — Progeny rows of Kursk millet grown at the Bellefourche Experiment 

 Farm, South Dakota, in 1909. These are the progenies of plants selected in the 

 rows shown in figure 1. 



Plate IV. Agropyron in the grass nursery at the Bellefourche Experiment Farm, 

 South Dakota. Fig. 1. — Rows of Agropyron cristatum in the grass nursery at the 

 Bellefourche Experiment Farm, South Dakota. In 1909 this grass was ten days 

 earlier in starting spring growth than any other species in the nursery. Fig. 2. — 

 Rows of Agropyron tenerum in the grass nursery at the Bellefourche Experiment 

 Farm, South Dakota. This is a valuable type of hay grass and breeding work 

 is being carried on in the hope of segregating a more drought-resistant strain.
