832 EXPERIMENT STATION RECORD. 



On the Brechin Castle estate plat 1, receiving the calcium nitrate, gave the 

 largest profit, $3.11 per acre, but in no case was the increase resulting from 

 fertilizer treatment sufficient to pay for the cost of the fertilizers. On the 

 Esperanza estate the calcium nitrate plat was also the best, showing an in- 

 crease of $8.30 in the value of the crop produced as compared with the control 

 plat. All plats treated with sulphate of ammonia showed a loss. On the 

 Malgretoute estate the results in no case showed an increa.se sufficient to pay 

 for the cost of applying the fertilizers. At this place an additional plat which 

 received an application of Peruvian guano at the rate of 3 cwt. per acre gave 

 a profit of $11.04 per acre. 



Manurial experiments on sugax cane, 1912—1915, J. de Vebteuil (Bui. 

 Dept. Agt: Trinidad and Tobago, llf {1915), No. 5, pp. 145-155, pis. S).— This 

 gives the results of an experiment to determine the value of different forms 

 of nitrogen used on plant and first rattoon canes and continues the work noted 

 above. 



The greatest profit from first rattoons at the Brechin Castle estate was 

 obtained from the plat receiving sulphate of ammonia and sulphate of potash, 

 and the lowest return from the plat receiving nitrogen only in the form of 

 sulphate of ammonia. The plat yielding the largest profit from the Esperanza 

 estate was the one receiving sodium nitrate in connection with phosphoric acid 

 and potash, while the least return was obtained from the plat receiving sulphate 

 of ammonia and potash and that receiving sulphate of ammonia alone. The 

 largest return from the Malgretoute estate was obtained by the u.se of calcium 

 cyanaraid with phosphoric acid and potash, and the smallest return from the 

 plat receiving calcium nitrate with phosphoric acid and potash. 



Proceedings of the Association of Official Seed Analysts of North America, 

 1914 (I'roc. Assoc. Off. Seed Atuil. of \o. Amcr.j J'J14, pp. 32). — A brief 

 rfsum6 of the development and activities of the association is given, together 

 with the following papers presented at the seventh annual meeting (E. S. R., 

 32, p. 200): The Necessity for Standardization of Methods, by E. Brown; 

 Uniform Methods of Sampling See<l, by E. D. Eddy; Apparatus and Metho<ls 

 Employed in Making Purity Tests of Seeds, by F. H. Hillman; The Enforce- 

 ment of the New Jersey Seed Law, by J. P. Helyar; The Wetnl Content of 

 Seeds, by A. L. Stone, which includes a table giving the number of seeds 

 borne by 21 annual, 17 perennial, and 8 biennial wee«ls; and The Weetl Con- 

 tent in Some Commercial Seeds, by I... H. Pammel and Charlotte M. King. 



A paper on The Germination of Seeds Buried Ten Years, by W. L. Goss, 

 points out that of 112 varieties 21, including only 4 weeds, never produced 

 any sprouts after being buried; 69 produced sprouts after 10 years' burial; 

 and the remainder perished during the interval. Of the 69 living at the end 

 of 10 years 26 germinated 51 per cent or better, 13 between 25 and 50 per 

 cent, 13 between 10 and 24 per cent, and 17 below 10 per cent. Attention is 

 further called to the fact that green foxtail germinated 70 per cent at the end 

 of 10 years. Broad leaved or bitter dock germinated 89 per cent in 10 years, 

 black nightshade 90 per cent, burdock 93 per cent, jimson wee<l 95 per cent, 

 ox-eye daisy 82 per cent, Canada thistle 21 per cent, and black mustard 25 

 per cent. The results of similar work by Duvel have been previously noted 

 (E. S. R., 17, p. 556). 



Results of seed inspection, 1914, J. P. Helt.\r and R. Schmidt (Neto 

 Jersey Stas. Bui. 279 (1915). pp. 3-^,')). — This bulletin tabulates the results of 

 analysis of 443 unofficial samples and 4.'>5 official samples of .see«ls. The official 

 samples included timothy, redtop, Kentucky and Canada blue gra.ss, orchard 

 grass, millet, meadow fe.scue, hard fescue, English rye grass, brome grass, red.
