 1920. — British mills are said to be adapted to use of American long-staple cottons and unable 

 to use the shorter staples of India and other countries. Definite organization of a research 

 institution is needed. The following suggestions were made: To establish in Manchester a 

 college of cotton where experts and planters can be trained; to promote intensive study of 

 races of all species of Gossypium, with careful records of all plantings; to establish branch 

 colleges in the more important centers of cultivation to complete training for local condi- 

 tions; to replace cultivation by natives on a small scale with plantations directed by trained 

 people. Success of American cotton is attributed to the fact that the work was undertaken 

 by intelligent farmers who evolved new and superior stocks and who did not have to contend 

 with vested interests of native cultivators. — 0. A. Stevens.

 31:552-553. 1 fig. 1920. — Seed was secured from Arizona. The variety is said to be 

 remarkable because of the resistance of its pollen to dry heat. It is very late, of fair quality, 

 and promising for Australian conditions. — L. R. Waldron.

 31:585-589. 1920. — Fourteen varieties were tested, the seed coming from America. They 

 averaged in yield 487 dozen ears per acre. The best yielding was Mammoth White Cory with 

 850 dozen ears, weighing 5.5 tons. Varieties are described and recommendations made. —

 of commercial fertilizers, especially phosphorus, upon maize for grain and fodder in various 

 districts of the province. Trials were made upon farmers' experiment plats. Usually the 

 application of the phosphorus in the shape of superphosphate showed a profit. — L. R. Waldron.

 ment.) Mitteil. Deutsch. Landw. Gesell. 35:563-565. 1920.— A comprehensive series of 

 experiments have been planned to determine the value of different methods of ensiling. The 

 German farmer is chiefly interested in the ensiling of grass and clover in order to save this 

 feed when weather conditions render it impossible to make hay. One experiment made 

 under such conditions is described. Timothy that had already become quite old because 

 the weather did not permit of cutting was ensiled. Feeding experiments with the ensilage 

 produced showed that 100 kgm. of the ensilage had the same feeding value for milk cows as 

 170 kgm. of mangels. — A. J. Pieters.
