Cowpeas and corn for silage and fodder, W. (tettys ( U. S. Depi. 

 A<ir.. l)i I'i.siiiii of A(/ri)'<tolo(/i/ V'lrc, 2J^^ pp. ILK Jj<i^. 2). — The desira- 

 bility and practical possibility of growing corn and cowpeas together 

 for silage and forage purposes are set forth by tiie author, his own 

 experience in growing, handling, and feeding these crops being made 

 the basis of the discussion. 



Details as regards the author's methods of planting, cultivating, and 

 liarvesting the crops together are given. Whip-poor-will cowpea is 

 considered the best variety for growing with corn. No noticeably 

 injurious effect on the quality of the butter has ))een observed from 

 feeding corn-and-cowpea silage to milch cows. Sowing cowpeas as a 

 catch crop after wheat proved profitable in the author's experience. 

 The pea vines were used for forage and the peas saved separately. 



Influence of the time of harvesting on the yield and quality of 

 hops, W. Behkexd {Bl. GevHten,, llopfen, and Kartofdhaii 1 {1899), 

 A^o. 12, pp. 4^65-47'^). — Hops were gathered at regular intervals of 5 

 days each from August 25, when thej^ were of a pure green color, to 

 September 14, when they were of a yellowish color, decked Avith 

 reddish specks. The yields of fresh and air-dried hops, amount of 

 resin and coloring material in the hops at different dates of gathering, 

 and the character of the beer made with them were determined. 



The late harvested hops gave the more satisfactor}" results in nearly 

 every respect. In yield of air-dry substance and resin content, and 

 in the taste and character of the beer made from the hops, each later 

 harvest surpassed the one preceding. Relative to the fermentation 

 period, acid content of the beer, and the color of the beer, no differ- 

 ences traceable to differences in the harvesting period could be detected. 

 The content of coloring material in the hops decivased with the late- 

 ness of the harvesting. 



The results of the inv^estigation lead to the conclusion that the best 

 time for harvesting hops is shortly after the appearance of the char- 

 actei-istic yellow color and reddish-colored flecks. 



Influence of size of seed tubers on the yield of potatoes, 

 Clausen (Ijindir. WcJmhl. ScldeKirHj-Uol.sfcl/i, 50 {1900), Xo. .'4. pj>. 

 62-GJt). — Experiments were made in planting Danish, English, and 

 Blue Six Weeks seed potatoes of different sizes under like conditions 

 on good soil. In every instance the greatest yields were ol)tained 

 from the largest-sized seed, and the largest proportional gains were 

 made b}' the earl}- Blue Six Weeks potatoes. The author draws the 

 following conclusions from the results obtained in the experiments: 

 Large seed tubers insure, through the greater tunount of nourishment 

 which the}' furnish to the young plants, a stronger growth and a bet-
