ducod 1,6S0 kg., the uninocxtlated l,5-l:!> kg. per hectare; a gain of 131 

 kg. by the use of Alinit. In Csanad, on alluvial soil containing humu.s, 

 the 3deld with Alinit was 1,5-1:2 kg. per hectare; without, 1,490 kg.; a 

 gain of 52 kg. by inoculation. In the district of Vizesda, on sand}^ 

 soil well treated with stable manure, the yield per hectare with Alinit 

 was 2,207 kg.; without, 1,738 kg., giving a gain of 469 kg. by inocu- 

 lation. Trials on sandy loam gave a yield with Alinit of 1,477 kg. per 

 hectare; without, 1,450 kg.; a gain of 27 kg. by inoculation. 



In all cases a gain in yield was obtained by the use of Alinit, and in 

 every instance but two, in Csanad and again in Vizesda, the gains were 

 made at a profit. The grain lodged but little on the inoculated plats, 

 and was little affected by rust. These features are considered of con- 

 siderable importance by the author and will be studied further. 



Experience notes on plat experiments, B. D. Halsted (Proc. Soc. Prom. Agr. 

 Sci. ISU'J, pp. 19-27). — Difficulties to l)e met in securing accurate results in field 

 experiments are noted and some suggestions given for overcoming them. 



Cassava culture in Florida [Tixidesman, 44 [1900), No. 2, p. 67). — A brief note 

 calling attention to the importance of this industry in Florida. 



Cassareep in Paraguay, J. N. Ruffin {U. S. Conmlar Epts., 63 [1900), No. 236, 

 pjy. 12, 13). — The growing of cassava in Paraguay is discussed, and the composition

The manuring of catch, crops, J. Leslie {Agr. Gaz. [Londort], 52 {1900), No. 

 1385, p. 36). — Experiments in which the profitable use of commercial fertilizers, 

 especially superphosphate and kainit, for catch crops of trifolimn and Italian rye 

 grass, are reported. 



The utility of the cowpea, A. M. Soule ( Tennessee Sia. lipt. 1899, pp. 67-71, 

 fig. 1). — The value of the cowpea as a green manure and forage crop is discussed and 

 suggestions given regarding its culture and use as a green manure. A comparison of 

 its food value with that of other forage crops is made. 



Notes on grasses, J. R. Fain {Tennessee Sta. Rpt. 1899, pp. 74, 75). — Suggestions 

 regarding seeding for succession. Timothy is regarded as excellent for iiermanent 

 pastures in Tennessee. 



Observations on buffalo grass, C. E. Bessey {Proc. Soc. Prom. Agr. Sci. 1899, 

 pp. 105,106). — Notes on the disappearance of this grass from the western plains, 

 with a brief account of a cultural experiment. 



Why grasses fail, A. 'SI. Soule {Tennessee Sta. Rpf. 1899, pjp. 71-73, fig. 1). — Lack 

 of a properly prejjared seed bed and the use of insufficient or imjjure seed are given 

 as reasons for the failure of many meadows. Suggestions regarding seeding are given, 

 together with a list of forage plants best suited to different soils and the amount of 

 seed to be employed in each case. 



The hop: Its culture and curing, marketing and manufacture, H. Myrick 

 {New York: Orange Judd Co., 1899, pp. 299, figs. 137). — "A practical handbook on 

 the most approved methods in growing, harvesting, curing, and selling hops, and on 

 the use and manufacture of hops. ' ' Chapters are given on the history and peculiari- 

 ties of the industry ; characteristics and composition of the hop plant and its fruit ; 

 climate and soils for hops; laying out hop yards; manuring, planting, tying, and 

 cultivation; hop pests; harvesting the crop; kilns for curing hops; curing, baling, 

 growing, sampling, and marketing hops; concentration in hop growing; expenses and 

 profits in the industry, and hop statistics. 



The w^ork deals especially with the methods of hop growing in New York and the 

 Pacific States. Methods and practices followed in England and Gennany are also
