the quality of the grain as feed. After unsuccessful trials with iron sulphate, 

 ammonium sulphate, sodium nitrate, and potassium chlorid as sprays, the 

 author suggests the obtaining of seeds free from Galium as the best method of 

 combating it. 



Chemical analysis showed a moisture content of 9.75, protein 11.25, fat 4.2, 

 nitrogen-free extract 64.42, crude fiber G.5S, and ash 3.S per cent. 



HORTICULTURE. 



[Horticultural investigations in 1912], R. S. Seton (TorJcshire Council 

 Apr. Ed. and Univ. Leeds [Pamphlet] 85, 1912, pp. 41-^5, fig. 1). — Data are 

 given on fertilizer tests with strawberries, together with variety tests of straw- 

 berries and other small fruits, and tests of various lawn mixtures, conducted at 

 the Manor Farm of the University of Leeds in 1912. 



Report of the government horticultural experimental fields in South 

 Holland for 1912, C. II. Claassen et al. {Verslag Rljkstmnbmitvproefvelden 

 Zuid-Holland, 1912, pp. 101). — This report is similar in nature to those issued 

 for pre\-ious years (B. S. R., 27, p. 842). 



Celery culture in Michigan, C. P. Halligan {Michigan Sta. Spec. Bui. 60, 

 pp. 2-'i, figs. 15). — A popular treatise on celery culture, including information 

 relative to soils and soil preparation, fertilizers, seeding, transplanting and 

 planting operations, cultivation, blanching, harvesting, storing, marketing, dis- 

 eases and insects, and varieties. 



Cucumbers as a cash crop, W. Postiff {Michigan Sta. Circ. 19, pp. 135- 

 138) .—This circular contains concise directions for growing cucumbers. 



Greenhouse tomato investigations, A. G. Bouquet {Oregon Sta. Bien. Crop 

 Pest and Ilort. Rpt. 1911-12, pp. H-50, figs. 5). — A study of various factors in- 

 fluencing early and sustained yield in greenhouse tomatoes. 



Out of 6 of the more important commercial forcing varieties tested Earliana 

 and Bonny Best were considered especially promising, the former for its char- 

 acteristics of earliness and productivity and the latter for its superior shape 

 and quality combined with fair yield. The greatest number of fruits were 

 secured from the flowers hand pollinated, although a superior yield was also 

 secured by jarring the plants as compared with natural pollination. 



Other phases being studied but not yet reported on include a study of indi- 

 vidual variety blossoms and blossom clusters with special reference to the 

 influence of variation in these characters on the production of marketable fruit, 

 and comparative tests of rows and plants fertilized and unfertilized. 



Notes on Jamaican vegetables, W. Haeeis {Bui. Dept. Agr. Jamaica n. ser., 

 2 {1913), No. 6, pp. 180-202). — This comprises popular descriptive notes on the 

 various vegetables occurring in Jamaica, including information relative to their 

 domestic utilization. 



Notes on fruits in Jamaica, W. Haeris {Btil. Dept. Agr. Jamaica, n. sei\, 



2 {1913), No. 6, pp. 159-180). — Notes similar to the above are given for the 

 economic fruits of Jamaica. 



Orchard spraying experiments in 1912, W. J. Moese and G. A. Yeaton 

 {Maine Sta. Bui. 212, pp. 57-72). — Additional spraying experiments with lime- 

 sulphur as a stibstitute for Bordeaux and with different arsenicals are reported 

 (E. S. R., 27, p. 440). The experiments were conducted in an orchard of Ben 

 Davis trees. 



Owing to a misunderstanding only one of the experimental plats was sprayed 



3 times, the first application being made before the blossoms opened. The other 

 plats were sprayed for the first time just after the petals fell and again about 

 3 weeks later. The results show a striking beneficial effect in the control of
