 for their control. Bull. North Carolina Dept. Agric. 40 8 :3-53. Illustrated. 1919.— This 

 paper is a descriptive account of 25 species of plants which are regarded as farm weeds. 

 Each species is illustrated by line drawings of the plant organs and means of control are 

 suggested. — R. A. Jehle.

 Agron. 11:304-306. 1919. — The loss in weight due to wounding was rapid during the first 

 week of storage at 8-10°C. and decreased thereafter. The increased loss of weight due to 

 wounding becomes extinct after 79 days when cut and uncut potatoes lose weight about 

 equally. Slight wounding occasions a loss of more than 2 per cent by weight. — F. M. Schertz.

 1919. — Experiments show that control of branching can be used to advantage. Because of 

 the peculiar habits of the plant, spacing can best be determined by local control experiments 

 for each variety of cotton. — F. M. Schertz.

1864. Ellis, J. H. Silage crops other than corn. Agric. Gaz. Canada 6: 540-541. June, 

 1919. — At the Manitoba Agricultural College each of 7 experimental silos was filled in the 

 autumn of 1918 with the following crops: corn (maize), Sudan grass, millet, alfalfa, mixed 

 cereals and peas in equal quantities, rape, buckwheat. Each crop was cut and ensiled when 

 it was judged that the proper stage had been reached. The silos were opened on February 3, 

 1919, and samples analysed. Palatability tests were conducted with dairy cows. The silage 

 in all 7 of the silos was in an excellent state of preservation. The cows showed a preference 

 for Sudan grass silage with alfalfa ranking second. The others were eaten with equal relish, 

 except that of buckwheat which was refused until all the others had been withheld. In gen- 

 eral, oats and peas, or Sudan grass, is recommended as the best substitute for corn for silage 

 where corn can not be grown successfully. — O. W . Dynes. 



1865. Gaines, E. F. Two important varieties of winter wheat. Washington [State] 

 Agric. Exp. Sta. Popular Bull. 116. 7 p., 2 fig. 1919.— Red Russian and Hybrid 128, tested 

 for yield from 1905 to 1918 inclusive showed 38.8 and 43.3 bushels respectively. The effect of 

 time of seeding on yield and amount of smut (Tilletia trilici) is presented on the basis of a 

 two-year average. Seeding on September 1 gave higher yield than earlier or later plantings. 

 The per cent of smut was in agreement with that reported in other Washington Experiment 

 Station bulletins (Bull. 125 and Popular Bull. 115).— F. D. Heald.

 Sci. Soc. 9:239-249. 1919.— Tests show sound, clean alfalfa seed kept under "fair condi- 

 tions" did not lose perceptibly in vitality in 23^ years; good commercial seed stored under 

 "rather disadvantageous conditions" germinated 46 per cent after 27 £ years; inferior seed 

 under "rather indifferent conditions" had 16.5 per cent viable seeds when 2\ years old.

 Agron. 11 : 247-252. 1919. — Tepary beans grown in the cool climates of the central and north- 

 ern California coast districts develop abnormally. The white Tepary is more prolific than 

 varieties of Phaseolus vulgaris in the semiarid interior districts of California. The white
