 1919. — Authors not jointly responsible. Yields are given for wheat, oats, barley, emmer, 

 flax, maize, potatoes, and certain forage crops for the years indicated and for earlier years for 

 certain crops. Also tables are presented showing the effect of the previous crop treatment 

 and cultural treatment upon the succeeding crop, especially upon the wheat crop. Weather 

 data are presented. — L. R. Waldron. 



70. Westover, H. I., and Samuel Garver. A cheap and convenient experimental 

 silo. Jour. Amer. Soc. Agron. 12: 69-72. 1920. — Experiments conducted at Redfield, S. Dak- 

 kota, showed that nearly all of the common plants can be preserved as silage which is readily 

 eaten by cattle. Motor oil barrels were used as experimental silos. — F. M. Scher'z. 



71. Wilson, J., and F. J. Chittenden. Some further experiments with potatoes. 

 Jour. Roy. Hortic. Soc. 44: 83-88. 1919. — I. Effect of spacing on yield. In 1917 nine different 

 spacings were used. In 1918 more spacings, namely sixteen, were used ranging from 9 to 18 

 inches between plants in the row. For spacings used in 1918 they reiterate their conclusions 

 drawn in 1917 as follows: "(1) The greater the space given to the individual plant the greater 

 the yield of that individual is likely to be. (2) The greater the number of plants on a given 

 area the greater the yield from that area will be." In spacing the other important factors 

 besides yield that must be given due consideration are "relative quantity of seed required," 

 "convenience in cultivating among and earthing up the plants and the need of circulation 

 of air as a preventative of disease." — II. Effect of different origin on yield of potatoes. The 

 author is of the opinion that locality alone is not a guarantee of seed potatoes of high pro- 

 ducing value. Other factors besides immaturity of seed potatoes at time of planting may be 

 important. Emphasis is laid upon the importance of uniform condition of temperature and 

 moisture in the soil during the growing and maturation periods. — H. A. Jones.

73. Anonymous. Introduction of the sugar-cane into the West Indies. Agric. News 

 [Barbados] 18: 242. 1919. — Information given is based principally on what is known of the 

 life and voyages of Christopher Columbus, and it appears that sugar-cane was not indigenous 

 to the West Indies but that it was introduced by Columbus on his second voyage about 1493. 

 — J . S. Dash. 



74. Barber, C. A. Reminiscences of sugar cane work in India. International Sugar 

 Jour. 21 : 390-395. 1919. — An historical account of the difficulty of cane growing in India due 

 to faulty methods of cultivation and an attack of Colletolrickum falcatum is presented. Bar- 

 ber worked out a system for cultivation and discovered resistant varieties which when intro- 

 duced to the cultivators made cane growing successful. — E. Koch.
