 253. 1920. — Sheep will eat the sorrel but will not injure the turnips if care is taken not to 

 overstock and to withhold the animals when the turnips first appear. These results are based 

 on several years experience. — N. J. Giddings.

 by planting sour clover {Melilotus indica) on the rows as a winter cover crop. — C. W.

 59. 4 V- [April 9.1 1921. — The author reports on a 4-year trial of orchard grass and timothy 

 seed from different sources. Orchard grass seed from Holland gave the largest total yield; 

 that from America nearly the same. Attention is called to the morphological and other 

 differences between these lots, — plants from Australian seed being dwarf and better adapted 

 to pasture mixtures, while those from American and Holland seed were tall. — Timothy seed 

 of Finnish origin and that from Galicia gave the best results; the American, the poorest. Some 

 selection work was done with timothy and with Festuca pratensis; the author illustrates the 

 possibilities of this work by giving a table showing the 3-year yields from individual plants. —

912. Stoa, Theodore E. Varietal trials with spring wheat in North Dakota. North 

 Dakota Agric. Exp. Sta. Bull. 149. 55 p., 4 fig. 1921. — Results of varietal trials are reported 

 for 7 stations in North Dakota: Fargo, Edgeley, Dickinson, Hettinger, Langdon, Williston, 

 and Mandan. Precipitation and temperature data are given for the different stations. At 

 the Fargo station yields given for a few varieties begin with 1892; most yields given begin 

 with 1901. Stem rust and drought have greatly influenced yields. Marquis has proved dis- 

 tinctly superior to other varieties of common wheat in the eastern and southern portions, 

 and somewhat superior in the central and southwestern sections; in the northwestern section. 

 Marquis has been outyielded by Power. The larger yields of Marquis were due partly, if not 

 wholly, to its greater earliness, thus escaping in part rust epidemics and effects of hot weather. 

 Bread produced from Marquis flour is superior to that produced from other varieties commer- 

 cially available. The data do not indicate that any exploited new varieties, such as Kit- 

 chener, Ruby, and Red Bobs, can replace Marquis in North Dakota. The new variety,
