EXPERIMENT STATION RECORD. 



reported of determinations of the mineral matter in white lupines on July 4, 11, 17, 

 27, 30, and August 10, 22; and of Spanish beans August 19, 27, September 4, 11, 21, 

 and October 2, 16. 



There was an increase in the total ash in both hulls and seeds of lupines up to 

 August 10. In the beans there was an increase in the case of the hulls up to Septem- 

 ber 21; in case of seeds until October 16. The lime and magnesia increased steadily 

 during the earlier stages of growth, but declined toward the end of maturity in case 

 of the hulls of both lupines and beans. In case of the seeds, however, there was a 

 continuous increase up to the end of ripening. Potash increased throughout in total 

 amount, but the percentage remained constant in the hulls and declined in the seeds. 

 Phosphoric acid increased up to a certain point and then decreased in the hulls, 

 although it did not appear to migrate to the seed to any considerable extent. 



Composition of tubers of different varieties of Jerusalem artichoke har- 

 vested in spring- and fall, P. Behkend (Jour. Landw., 52 (1904), No. 1-2, pp. 

 127-143). — Historical notes on the study of the chemical composition of Jerusalem 

 artichoke tubers are given and the author's work is described. Analyses of 7 samples 

 each of fall harvested and spring harvested tubers are reported. In each case the 

 composition of the fresh sample and of the dry matter is given. 



Analyses of 3 samples, made from 3 to 4 months after storing, are also reported. 

 A summary of the analyses is given in the following table:

Variety tests with barley, W. Edler (Fiihlhig's Landw. Ztg., 53 (1904), Nos. 9, 

 pp. 328-331; 10, pp. 372-376; abs. in Deut. Landw. Presse, 31 (1904), No. 22, pp. 254, 

 255). — Twelve cooperative tests were made with Goldthorpe, Chevalier, and Hanna 

 barley. The average yields of grain per hectare were 3,316 kg., 3,252 kg., and 2,843 

 kg., and the average yields of straw, 4,111 kg., 4,090 kg., and 3,862 kg., respectively. 

 The average weight per liter was 692 gm., 688 gm., and 685 gm. for Chevalier, Hanna, 

 and Goldthorpe, respectively. Goldthorpe stood first in the weight per thousand 

 grains, and was followed by Chevalier and Hanna in the order given. The weight 

 per thousand grains in the series of tests varied from 43.26 gm. to 50.48 gm. In 

 mealiness Goldthorpe ranked first and Hanna last. 



The results also show that the locality had a marked influence on the mealiness of 

 the grain. Goldthorpe contained 10.10 per cent of protein in the dry matter, Cheva- 

 lier 10.62 per cent, and Hanna 10.73 per cent. Attention is called to the following 

 classification of brewing barley as based on the protein content: Under 9 per cent of 

 protein in the dry matter first grade, 9 to 10.5 per cent second grade, 10.5 to 11.5 per 

 cent good, and over 11.5 per cent medium and poor.
