tictiviiies of the Institute in promoting cotton production in tlie British Empire 

 are briefly outlined. A list, comprising some 97 reports, special articles, etc., 

 dealing with various phases of the crop which appeared in the Bulletin of the 

 Institute from 1905 to 1917, inclusive, is also presented. 



Cottonseed by-products {Nature [Londo)i], 103 {1919), No. 2582, pp. 153, 

 154). — A paper presented before the Royal Society of Arts by E. C. de Segundo 

 on The Removal of the Residual Fibers from Cotton Seed and their Value for 

 Nontextile Purposes is briefly reviewed. The development of ginning ma- 

 chinei'y for the more complete removal of lint from cotton seed and a process 

 for removing the last trace of fiber from the hulls after decortication comprise 

 the principal features dealt with. 



Fiber plant investig'ations [in South. Africa], E. Holmes-Smith {So. 

 African Jour. Indus., 2 {1919), No. 2, pp. 157-172). — This describes a survey of 

 the Transkei and southeastern coastal districts of the Cape Province for the 

 purpose of ascertaining their suitability to fiber production and to the estab- 

 lishment of the fiber industry. It is concluded tliat the region is well adapted 

 to the production of hard fibers, Agave riglda, Furcrcea gUjantea, and Phormium 

 tenax being recommended in particular. Directions for growing the crops and 

 for preparing the tiher for market are included. 



Production of flax fiber and seed flax in Canada, P. C. Robertson {U. S. 

 Dept. Com., Com. Rpts., No. 124 {1919), pp. 1031-1034). — A report on the present 

 status and future prospects of the flax industry in Canada. 



Tests with flax varieties, G. S. Gokdon {Jour. Dept. Agr. Yictoria, 17 {1919), 

 No. 3, pp. 164-170, figs. 4). — Limited variety tests, conducted at Werribee (Vic- 

 toria) during 1918 with seed of both American and English origin, are briefly 

 noted. 



The flax industry [in Victoria], J. Robilliakd {Jour. Dept. Agr. Victoria, 

 17 {1919), No. 4, pp. 222-230, figs. S).— Field practices and cultural methods em- 

 ployed in growing the crop and the preparation of the fiber ft)r market are 

 described. 



Lalang grass as a paper material, B. J. Eaton {Agr. Bui. Fed. Malay States, 

 7 {1919), No. 1, pp. 28-32). — This comprises a brief discussion of a report on 

 lalang grass {Imperata arundinacea) as a paper material, presented by the 

 Imperial Institute and previously mentioned (E. S. R., 40, p. 823). It is stated 

 that this grass compares favorably with Algerian esparto grass, but is inferior 

 to Spanisli esparto. 



Official grain standards of the United States for oats, D. F. Houston {JJ. S. 

 Dept. Agr., Bnr. Markets Serv. and Regulatory Announcements, No. 46 {1919), 

 pp. 6). — This contains the order of the Secretary of Agriculture establishing the 

 official standards for oats, effective June 16, 1919. 



Handbook official grain standax'ds for oats {U. S. Dept. Agr., Bur. Markets, 

 1919, pp. 6). — This comprises a tabulated and abridged description of the offi- 

 cial standards for oats compiled from the publication noted above. 



The spraying of Irish potatoes, II. W. Leiby {Bui. N. G. Dept. Agr., 40 

 {1919), No. 3, pp. 38, figs. 12). — This describes experimental work covering the 

 period of 1913-1918, inclusive, conducted at the Buncombe County substation in 

 an effort to ascertain the best practical means of controlling the important insect 

 and disease pests affecting the fall or late Irish potato crop in North Carolina. 

 The plan of the experiment comprised observations on the comparative value 

 of spraying with Bordeaux mixture to control blight, hand-picking to control the 

 Colorado potato beetle, and spraying with Bordeaux mixture and arsenate of 

 lead combined to control both the beetles and blight. The results secured dur- 

 ing each year of the experiment are discussed in detail and may be summarized 

 as follows :
