Approximately 60 per cent of all the tests here conducted, as 

 analyzed in 1922, were successful or partially successful. It is 

 significant that Hungarian bromegrass, with 76 per cent of the 

 trials successful or partially successful, outranked timothy, 

 which, however, was second best in yielding capacity. These 

 species were followed, in the order named, by Kentucky blue- 

 grass, Canada bluegrass, white clover, red top, and orchardgrass. 



Season for Sowing. — In the Northwest, and as far south as 

 Utah and northern Nevada, seeding in the fall appeared to give

 areas were superior to those seeded in the spring in that (i) 

 germination took place more promptly, (2) the development of 

 the seedlings was more uniform, and (3) the loss of seedlings 

 from adverse conditions was less (Fig. 11).

In the mountains, from central Utah and central Nevada, and 

 throughout the Southwest, spring or early-summer seeding gave 

 better results than did autumn seeding. In this region the 

 soil usually becomes so dry late in the spring that a goodly 

 proportion of the seedlings originating from seed scattered in
