when Bpring sown. Examples of varieties <if the fin I type are cited. All changing over of 

 winter wheat into spring wheat is not considered a- due to the acquisition and inheritance 

 of new characters, bul rather as the expression <>f inherent possibilitit already presenl in 

 certain strains or varieties. The ability thus to change over may be increased and fixed by 

 selection. — C. K. Leighty.

S9. Leighty, Clyde E. The place of rye in American agriculture. U. S. Dept. Agric. 

 Yearbook 1918: 169-185. 1919. — Rye is receiving more attention now by farmers, agricultural 

 colleges, and experiment stations. Statistics are given showing the increased production 

 in the United States. Rye and wheat as foodstuffs are compared quite favorably to rye. 

 The reasons given for increased rye production are: the present unusual food situation, 

 hardier nature, adaptability to poor soil, distributes labor in farm management, immunity to 

 Hessian fly, excellence as a cover crop, traps nitrates through the winter, excellence for 

 green manure, value" as a nurse crop, quality as a soiling and silage crop, and finally utility 

 a? pasture crop. The grain is a good basis for flour mixtures, but is not a very good animal 

 feed. The straw has high value as packing material, but not much value as feed. Article 

 closes with a plea for overcoming the prejudice against rye and increasing its production and 

 use in the United States. — C. J. Shirk.
