234 EXPERIMENT STATION RECORD. 



lu another series of tests, comparing cow manure witli compost, the quan- 

 tities applied being based on the chemical analyses, the best yields amounting to 

 666.6 lbs. of seed and 333.3 lbs. of lint per acre, were secured from the use of 

 2,640 lbs. of compost per acre. This plat gave 82 lbs. more lint per acre than a 

 plat which had received 5,428 lbs. of cow manure and 272 lbs. of acid ])hosphate. 



In a third series of experiments, with the use of commercial fertilizers alone 

 and in combination, an application of 1,360 lbs. of acid phosphate and 320 lbs. 

 nitrate of soda per acre stood first in yield, with 754.7 lbs. of seed and 377.3 

 lbs. of lint per acre. This plat also ranked first in early maturity, 94 per cent 

 of the crop being gathered by September 28. The effect of acid phosphate in 

 hastening maturity was noticed in the results secured. A home mixture, ap- 

 plied at the rate of 595 lbs. per acre, containing 1.6 per cent of phosphoric acid, 

 0.64 per cent of potash, and 0.54 per cent of ammonia less than Peruvian guano, 

 gave an average of 43.8 lbs. of seed cotton more per acre than the guano, which 

 was given at the rate of 500 lbs. per acre. 



The results with a number of varieties of cotton compared liy the station 

 during a series of years are compiled and presented in tallies. It is shown that 

 Texas Oak led in yield twice and ranked third once, Crossland stood third 

 once, Bates' Improved Prolific ranked first once and second once, Doughtey's 

 Long Staple and Jackson Limbless each stood second once. Peerless ranked 

 s-econd and third once, and Drake Cluster and Texas Burr were each third once. 



The Aldrich system of growing cotton and corn, which consists in growing the 

 cotton rows and corn rows alternately in pairs throughout the same field, was 

 compared with 2 check plats, one in cotton and the other in corn. The cotton 

 check produced 1,599.2 lbs. of seed cotton per acre, worth $72.60, and the corn 

 check 36 bu. of corn per acre, worth .$21.60, or a total of $94.20 for 2 acres. 

 The plat grown by the Aldrich system produced an aggregate value of f 13.58 

 less than the check plats, or $6.79 less per acre. 



The cultivation of maguey in the Philippine Islands, 11. T. Edwards {Phil- 

 ippine Bur. Agr. Farmers' Bid. 13, pp. 25, pis. 9). — A general account is given 

 of the history and distribution of maguey in the world and in the Philippine 

 Islands. The plant is described, its climatic and cultural requirements noted, 

 and its value and uses pointed out. In connection with directions for harvest- 

 ing, a description of the extraction of the fiber and fil)er-extracting machinery 

 is presented. 



Composition of soy beans, W. Freak {Pc>iiisylr(i)ii(i Sta. Rpt. 1905, pp. 

 39, 40). — The composition is reported of the grain of Cross Bred No. 6, Early 

 Black, Ita San, and Early Green soy beans. 



The conclusion is drawn from the data that for seed the Cross Bred No. 6 

 and the Early Black are the safer varieties in the more elevated and northern 

 part of Pennsylvania, and that Ita San and Early Green, which are early enough 

 for the southern and less elevated portions of the State, are preferable for that 

 region on account of the size of the plants and their productiveness. None 

 of these varieties gave a yield of 35 bu. per acre, which was secured by the Mas- 

 sachusetts Station from the Medivnn Early White variety. 



Experiments with sugar beets, season 1905, F. W. Woll, R. A. Moore, and 

 A. L. Stome {Wisco)isi)i Sfa. lipt. 1905, pp. 356-362. (h>m. 1). — Variety, fertil- 

 iser, and culture tests were made. 



In the variety test the highest yield, 15,631 lbs. of beets per acre, was secured 

 from Breiistedt Kleinwanzleben. The yields of beets and of sugar from Breu- 

 stedt Kleinwanzleben, Schlanstedt Kleinwanzleben, and Heine Kleinwanzleben 

 were above the average for the entii'e field. The sugar content of the beets 

 ranged from 16.4 per cent in Hoerning to 17.7 per cent in Schaefer. The use 

 of a complete fertilizer in growing sugar beets showed a mai'ked improvement
