FIELD CROPS. 1071 



The results show that while the light-weight seeds contain a somewhat larger per- 

 centage of nitrogen, phosphoric acid, and potash than the heavy-weight seeds, the 

 total amount of these substances is much less. One hundred kernels of heavy- 

 weight barley contained about one-third more phosphoric acid, nearly one-half more 

 nitrogen, and about 10 per cent more potash than 100 light-weight kernels, and in 

 3 samples of oats 100 heavy-weight kernels contained about l.S times as much phos- 

 phoric; acid, 1.5 times as much potash, and nearly twice as much nitrogen as 100 

 light-weight seeds. About the same total amount of phosphoric acid and potash and 

 twice as much nitrogen was found in 100 heavy-weight wheat kernels as in 100 light- 

 weight seeds. 



The germination and viability of frost-damaged grains, 0. Glarum (Norges 

 Landbr. Hoiskoles Akervekstforsog 1902-3, pp. 79-9H). — A study of frost-damaged 

 Grand Mogul, Ligowo, and Grenaa oats showed that the plumule had sustained the 

 severest injury. If not killed by the frost, the plumule may lack the required energy 

 to push to the surface of the soil and may be prevented from pushing upward by a 

 divided, wrinkled, or bent condition resulting from frost injury. — f. w. woll. 



Forage and pasture plants of Iceland, II, S. Stefanson and H. <i. Soderbaum 

 (A'. Land/. Akad. Hand/, och Tidskr., -}■>' {1904), No. 5, pp. 324-368).— A former 

 report on this subject has been previously noted (E. S. R., 14, p. 432). 



The moisture, ash, crude protein, ether extract, cellulose, pentosans, total and 

 digestible albuminoid nitrogen, and indigestible albuminoid nitrogen content of the 

 following plants is reported: Poa annua, P. alpina, Glycerin distans, Calamagroslis 

 neglecta, Nardus stricta, Anthoxanthum odoratum, Phleum alpinum, Juncus ballicus, 

 J. trifidus, Achillea millefolium, Trifolium repens, Vicia cracca, Rumex acetosa, Poly- 

 gonum viviparwm, Cerastium vulgare, Galium verum, Menyanthes Irifoliata, Comarum 

 palustre, Geum Hvale, Leontodon autumnalis, Erigeron neglectus, Salix lanata, 8. glauca, 

 S. herbacea, ('all mm vulgaris, and Loiseleuria procumbens. — f. w. woll. 



Alfalfa in Indiana, A. T. Wiancko and M. L. Fisher (Indiana Sta. Bid. 101, 

 pp. 205-219). — General directions for the culture and uses of alfalfa are given, and 

 the results secured in cooperative culture tests are briefly reported. 



The results showed that a good stand may be obtained on almost any of the soils 

 of the State and that the more open soils are to be preferred. Inoculation proved 

 desirable and in most cases necessary. Although not very definite, the results fur- 

 ther indicated that alfalfa should be sown from early April to June, and that sowing 

 without a nurse crop is preferable. 



Reports from 38 farmers in various parts of the State show that with 32 the crop 

 was a success. The causes of failure reported are weeds, need of inoculation, poor 

 drainage, early pasturing, and drought after seeding. 



Culture experiments with Imperial barley, 1901-1903, S. Rhodin (K. 

 Landt. Akad. Handl. och Tidskr., 43 [1904), No. 5, pp. 321-323).— Four varieties of 

 Imperial barley, Goldthorpe, Erh. Frederiksen, Webb Bearded, and Svalof Primus, 

 were grown for 3 years at the experiment station of the Swedish Agricultural Acad- 

 emy. 



The highest average yield, 2,613 lbs. per acre, was produced by Svalof Primus, 

 followed by Frederiksen with an average yield of 2,529 lbs. per acre. Svalof Primus 

 also ranked first in quality, combining with the high yielding power a relatively low 

 moisture, protein, and hull content and a high kernal weight. — f. w. woll. 



Corn improvement in Indiana, A. T. Wiancko (Indiana Sla. Bui. 105, pp. 275- 

 322, figs. 15). — This bulletin discusses the selection and preparation of seed corn, 

 including the tests for germination and vitality, and brings out by means of illustra- 

 tions and notes the good and poor shape of the ears, variation and uniformity in the 

 kernels, good and bad spacing of kernels at the cob, the proper width of the furrows 

 between the rows, and desirable and undesirable types of kernels. The score card
