896. Hbrtel, H. Landbruget i 1920. [Agriculture during 1920.] Tidsskr. Land0konomi 

 1921 ': 1-38. 1021. — The 1920 harvest for the entire nation is stated as follows in millions of 

 dobbeltcentner (200 pounds) : Wheat 1 .89, rye 3.20, barley 5.13, oats (5.84, buclcwheat0.02. Den- 

 mark is endeavoring to raise clover seed for export, but during 1920 the quantity harvested 

 was insufficient even for domestic needs. Experiments with clover seed from Bohemia have 

 demonstrated that the resulting seed is not as good as Danish seed. — Albert A. Hansen. 



897. Kinney, E. J., and George Roberts. Soybeans. Kentucky Agric. Exp. Sta. 

 Bull. 232. 23-58. 1921 . — This bulletin reports results of a study of soy beans in Kentucky over 

 a period of more than 7 years. A discussion is given of the utility of the soy bean crop, its 

 value under dii'ferent conditions as compared with cowpeas, varieties, — with description of the 

 most important ones, — yields of seed and hay, the place of the soy bean in the rotation, culture 

 of soy beans, care of the crop and of soy beans in mixture with corn and other crops. A 

 discussion is also included of the value of soy beans for silage. It is pointed out that soy 

 beans will give good yields on poor fields, which will not successfully raise red clover, thus 

 supplanting clover in the rotation. — IF. D. Valleau. 



898. LiECHTi, P., UND E. RiTTER. Ueber die Wiesendiingung mit Giille unter besonderer 

 Beriicksichtigung der Verwertung des Giillenstickstoffs bei der Griinfuttererzeugung. [Pas- 

 ture fertilization with liquid manure, with special reference to the utilization of the nitrogen in 

 the production of green feed.] Landw. Jahrb. Schweiz 35: 1-66. 1921. — This describes plat 

 e.xperiments with liquid manure and other fertilizers for the period 1911-1918, inclusive, in a 

 study of the effect of fertilizer treatment on yield and composition of pasture grasses. Con- 

 siderable tabulated data are presented giving the results of chemical analyses of the dry 

 matter produced under the various fertilizer treatments. — /. D. Luckett. 



899. McDonald, A. H. E. Trial of Jerusalem artichokes. Agric. Gaz. New South Wales 

 32: 587. 1921. — It was found at WoUongbar Experiment Farm that artichokes can not 

 compete with sweet potatoes as fodder for pigs. Sweet potatoes yield more, remain in the 

 ground without rotting, and the surplus crop, if any, can be marketed. Artichokes were 

 found to be more sucessful at Hawkesbury. — L. R. Waldron. 



900. McGiLL, J. British grasses. 65 pi. McGill and Smith, Ltd.: Ayr, Scotland, 

 1920. — Photographic illustrations of 65 species of British grasses are given, each plate labeled 

 with the common and scientific names and with brief notes of the habit and agricultural value 

 of the grass. — C. V. Piper. 



901. Maiden, J. H. Newly recorded weeds. Agric. Gaz. New South Wales 32: 580. 

 1921. — Amaranthus deflexus and Xanthiutn commune are reported as new to the Common-

902. Mathieu, E. H. An experiment with Sorghimi vulgare, the Great Millet or Juar, 

 from the Bombay Presidency. Gardens' Bull. Straits Settlements 2: 423-426. 1 pi. 1921.— 

 A race of Sorghum vulgare from the Tapti valley in western India was found to grow and 

 produce grain freely in Singapore, while another from Ahmednagar, also in western India, 

 ran to leaf. The former strangely enough gave the largest yields after transplanting. — /. //.

903. Mathieu, E. [H.] Roselle fibre. Agric. Bull. Federated Malay States 8: 231-241. 

 1920 [1921], — The cultivation and fiber-value of Hibiscus sabdariffa var. aliissima are dis- 

 cussed. — I. H. Burkill.
