 52 manure and. lime, 33 manure and lime and commercial fertilizer, 7 a nurse

Indian corn, its production and improvement, G. A. Crosthwait (Idaho 

 Sta. Bui. 57, pp. 59, pis. 11). — This bulletin, a treatise on corn culture, dis- 

 cusses corn culture, seed corn, and corn improvement, together with the work 

 in this line carried on at the station. The selection and preservation of seed 

 corn and the methods of making germination tests ai'e described, and the rules 

 of exhibiting corn in Idaho, the score card, and the rules of judging are given 

 in detail. The varieties of corn tested at the station from 1904 to 190G, inclusive, 

 are enumerated, and the progress of the work in selecting strains adapted to 

 Idaho conditions is mentioned. 



The selection of seed corn, C. G. Williams {Ohio Sta. Circ. 11, pp. 8). — ^This 

 circular discusses the selection of seed corn with reference to the time of selec- 

 tion, condition of the plant, weight, length and position of the ear, and its care 

 after gathering. 



Selecting seed corn in the fall before the crop is harvested is advised. In the 

 experience of the station, seed selected from plants where the stand and other 

 environment wAs normal gave an average yield of 3.23 bu. per acre more than 

 seed selected in the ordinary way, and hea\y weight seed ears exceeded medium 

 weight seed ears in yield by 5.9 bu. per acre, while medium long seed ears ex- 

 ceeded medium short seed ears by 4.85 bu. per acre. It was observed that vigor 

 of plant, as shown by ability to stand upright, is hereditary. Ear rows growing 

 side by side gave a variation of from to 56 per cent of Itroken plants. 



Descriptions and classification of varieties of American upland cotton, 

 J. F. DuG(iAR (Alabama Collcf/c Sta. Bui. I'l'i, pp. 1.1,2, pis. 36, flgs. 35).— For the 

 purpose of classification the short staple or upland varieties of cotton are grouped 

 as follows: Cluster varieties, or Dickson type; semi-cluster varieties, or Peerless 

 type; Kio Grande varieties, or Peterkin type; King-like varieties, or King type; 

 big boll varieties, or Truitt type; long limb varieties, or Petit Gulf type; inter- 

 mediate varieties, or various types ; and long staple upland varieties, or Allen 

 type. Each one of these groups as well as a long list of individual varieties is 

 described. Tables are given showing the number of bolls required to make 1 

 pound of seed cotton, the arrangement of varieties according to percentage of 

 lint, and the weight of 100 seeds. 



In experiments on productiveness, among the varieties tested at the station 

 for a considerable number of years. Peerless, Peterkin, Russell, and Truitt have 

 frequently stood near the top of the list. Of those tested only a few years, 

 Cleveland, Cook Improved, Jackson, Layton, Pullnot, and Toole have given good 

 results. 



Sea Island cotton: Its culture, improvement, and diseases, W. A. Orton 

 (U. 8. DcjJt. Agr., Farmens' Bid. 302, pp. .'iS, figs. i3).— This bulletin discusses 

 the geographical distribution of Sea Islf\nd cotton in the United States, the ideal 

 crop requirements, the possible extension of the Sea Island cotton-producing 

 area, markets, farm practices, cultivation, fertilizers, preparation of the land, 

 seed selection, handling the crop, and the diseases and insect enemies which com- 

 monly attack the plant. 



A, B, C of cotton planting, D. Morris (Inip. Dept. Agr. West Indies, Pam- 

 phlet 45, 1907, pp. OS, figs. 5). — This is an enlarged edition of a former publica- 

 tion on this subject, previously noted (E. S. R., 16, p. 152). 



Bermuda hay (Oklahoma Sta. Rpt. 1906, p. 21). — Experiments at the station 

 with Bermuda grass have shown that this species is not only adapted to pasture 

 but is also of value as a hay crop. Two and one-half acres of upland soil 

 planted to hardy Bermuda grass .June 29 and 30,*19(i5, i)roduced at the rate of 

 5.08 tons per acre from three cuttings in 1906.
