Fertilizer experiments with hops (/>/. (h-n^icn- ITopfcn-v. Kartoffdhau, 1 {1899), 

 No. 9, p2). 323-330). — Summarized iVHults oljtaincd 1)y the (lorinaii Hoj) Culture 

 Association in 1898. 



Fertilizer experiments with hops, T. Remy {Bl. Gerden- Ilopfcn- u. Kartofi'clhaii, 

 1 {1S99), Xo. 10, pp. 341-362). — Report on the use of different nitrogenous fertilizers 

 for hops. The exjieriments were made at the Experimental Institute for Brewers in 

 Berlin and, in cooperation with the institute, by growers in different hop districts in 

 Germany. Barnyard manure was one of the ]>est fertilizers used. Suljihate of 

 ammonia and nitrate of soda proved good substitutes for this manure. Large amounts 

 of potash in one experiment seemed to increase the total ether extract and resin 

 content of the hops grown. 



Notes on five years' experiments on hop manuring, B. Dyer {London: Yin- 

 ton & Co., Ltd., 1900, pp. 21, figs. 12). — The ol)ject of these experiments has been 

 " to ascertain how far nitrate of soda in the presence of an abundant supply of phos- 

 phates and potash can be advantageously used as a source of nitrogenous food for 

 hops." Increasing amounts from 200 up to 400 lbs. per acre were used. The hops 

 grown were examined independently by a brewing chemist and a commercial hop 

 dealer, and their relative values judged. In no instance did the use of nitrate affect 

 the quality of the hops injuriously. On the other hand, it considerably increased 

 the total yield of hops, and had a decidedly beneficial effect on their quality as com- 

 pared with hops grown on plats which received no nitrate. The author believes 

 that on soils otherwise liberally manured 400 lbs. per acre of nitrate of soda is a per- 

 fectly safe dressing for hops. In the author's experience 600 lbs. per acre has given 

 the best results in a dry year. 



Culture of legumes, C. Fruwirth {Anhcm do- TU'dsenfruchtc. Berlin: Paul Parey, 

 1S9S, pp. 274, figs. 69). — This is another contribution to the series of Thaer-Bibliothek 

 agricultural books. The work is confined to podded plants such as beans, peas, and 

 the like. The general part of the book treats of the botany of legumes, structure and 

 development of the plant and seed, requirements as regards soil and fertilizers, basic 

 principles in the culture of legumes, statistics of legume cultui'e, uses of legumes, and 

 place of legumes in a syi^tem of rotation, and as a salable seed crop. The special 

 part, occupying little more than half of the book, is devoted to considerations of the 

 botany, characteristics, culture, and uses of 24 species and varieties of legumes. 



The present status of rice culture in the TJnited States, S. A. Knapp ( U. S. 

 Dept. Agr., Division of Botawj Bui. 22, 2>p. 56, pis. 5).— This bulletin notes briefly the 

 history of rice and its introduction into the United States, and gives in detail 

 methods of rice culture in South Carolina, Georgia, Louisiana, and southeast Texas, 

 dealing especially with systems of irrigation and the use of the gang plow, disk har- 

 row, drill and broadcast seeder, and twine binder as applied to rice culture in south- 

 west Loiiisiana and southeast Texas. 



Historic and modern methods of milling rice are discussed, as well as the uses of 

 rice and its by-products, soils adapted to rice culture, prospects for the extension of 

 the industry in the United States, and the culture of rice in Asia and the Pacific 

 Islands. Much statistical matter relative to imports of rice, production in the United 

 States, etc., is also intruded in the bulletin. 



Wild rice in Minnesota and Wisconsin, A. E. Jenks {Amer. Thresherman, 3 

 {1900), Xo. 2, pp. lS-54,figs. ,9).— Methods followed by the native Indians in sowing 

 and harvesting wild rice in these States are given. 



Sugar-beet investigations in Wisconsin during 1898, F. W. Woll ( Wiscon- 

 sin Std. Rpt. 1S99, pp. 249-262, fig. 1). — The data of this article have already appeared 

 in Bulletin 71 of the station (E. S. R., 11, p. 143). 



Culture of sugar beets in Egypt, G. P. Foaden {Jour. Khediv. Agr. S'oc. and 

 School Agr., 2 {1900), Xo. 2, pp. 76-82). — Brief review of the sugar-beet industry in 

 Germany and France, with notes on the present status of the industry in Egypt.
