 — The writer gives as reasons for the marketing of inferior seeds, mentioning as the 

 most important, the farmers' practice of selling one another adulterated seeds, of saving 

 screenings for seed, and of purchasing second or third-grade seed for planting. It is 

 urged that the farmer selling seed for seeding purposes should be required to comply with the 

 same regulations as the dealer. It is suggested that the logical method of handling seeds in 

 interstate commerce is through the medium of national grades, which would be flexible, yet 

 place a premium upon high grade seeds.— M. T. Munn.

 Exp. Sta. [Geneva] Bull. 474: 1-32. 1920.— These experiments were conducted at Geneva, 

 New York, during 5 seasons and were devoted chiefly to a comparison of 6- by 36-inch 

 planting with 15- by 36-inch planting. Two varieties of Solanum tuberosum belonging to the 

 Rural group were used. In different seasons, the thick planting produced from 55.4 to 79.2 

 per cent more tubers than the thin planting, but as the tubers were of smaller average size 

 the difference in total weight of crop was much less; viz., 14.4 to 36.9 per cent. The average 

 net yield (total yield minus "seed") of tubers weighing over one ounce was 34.7 bushels per 

 acre. More than half of this difference (18.7 bushels) consisted of tubers over two ounces 

 in weight. — F. C. Stewart. 



659. Stone, A. L. Seed legislation and the farmer. Seed World 71°: 23. 1920.— The 

 conclusion is reached that seed laws should not favor the farmer, but should be designed 

 only to protect him from technical phases of seed trade and commerce. The practice of 

 exempting farmers under the seed laws is not considered desirable.— M. T. Munn.

 as well as on the method of preparation. — H. G. Barbour.

 Exp. Sta. 5': 199. 2 pi. July, 1920. — The article comprises a brief discussion of the essen- 

 tial points in handling cane and producing high grade syrup from the juice. — R. C. Thomas. 



663. Thorne, Chas. E. The maintenance of soil fertility in Hamilton county, Ohio. 

 Monthly Bull. Ohio Agric. Exp. Sta. 5^°: 170. 1920.— This involves a report of the benefits 

 from fertilizers and limestone in a corn, soybean, wheat, clover rotation. A detailed com- 

 parison of certain varieties is given. — R. C. Thomas. 



664. Thorne, Chas. E. A crop rotation for a hog farm. Monthly Bull. Ohio Agric. 

 Exp. Sta. 5^: 131. 1920. — Corn, being deficient both in protein and lime, is inadequate as a 

 muscle and protein builder. Defective features in a corn, wheat, clover rotation are pointed 

 out. The value of the soy bean as a feed crop, and for the production of bone, protein, and 

 pork is discussed. Consideration is given to the relative manurial value of straw and stover.
