A hybrid from teosinte and corn, F. L. de ^'Ir.MORI^- {Bui. Sac. Bot. France, 

 54 (1907), Xo. 1. pp. 39-.'f2, pi. 1). — This article discusses and describes the 

 hybrid obtained by pollinating the female flowers of teosinte with pollen from a 

 small white variety of corn. The actual work of hybridizing was done by G. 

 Laurent. The application of pollen from teosinte on the female blossoms of corn 

 gave no results. As the result of xenia, some of the grains were complex and in 

 some instances were joined together in pairs. 



Brewing- barley from a scientific and practical standpoint, P. Bauer 

 (Wclinschr. Bran.. >', (1907), Xos. 19, pp. 2i9-255; 20, pp. 261-266; 21, pp. 

 273-276). — ^As a result of his observations the author advises for early sowing 

 the use of a variety of barley low in protein, with a fully developed kernel, 

 strong in germination, and one which produces a strong stem with compara- 

 tively few joints. The use of nitrogenous fertilizers in. minimum quantities is 

 recommended and it is believed that barley should occupy the third or fourth 

 place in the rotation. When barley must be grown as the second crop in the 

 rotation a heavy and timely application of lime, potash, and phosphoric acid 

 with common salt should be made. High yields of first quality are considered 

 possible only when the soil is supplied with all the plant food elements. It is 

 stated that potash and sodium tend to increase starch and sugar and to decrease 

 protein in the grain, while lima and phosphoric acid strengthen the stem and 

 thereby reduce the danger of lodging. 



Cotton fertilizer experiment. A. W. Blair {Florida Sta. Rpt. 1907. pp. 

 XXIV-XXYI). — The standard application per acre used in this work consisted 

 of 200 lbs. of acid phosphate. 150 lbs. of cotton-seed meal, and 50 lbs. of muriate 

 of potash. The plat receiving this application produced at the rate of 465 lbs. of 

 seed cotton per acre, while the plat receiving no fertilizers produced at the rate 

 of 122A lbs. A plat receiving one and one-half times the standard formula 

 yielded at the rate of 015 lbs. of seed cotton per acre, but when the standard 

 amount was doubled the yield was not quite so good as with 600 lbs. 



The author believes that from 400 to 600 lbs. per acre of a good complete fer- 

 tilizer is the most profitable quantity to apply, and that the results have shown 

 that the practice of applying 100 to 200 lbs. of a one-sided fertilizer to cotton in 

 .Florida is poor economy. 



Manuring of seeds hay, W. Allan (Edinb. and East of Scot. Col. Apr. Bui. 

 13. pp. 17, dfjni. 1). — Cooperative fertilizer experiments on hay lands were car- 

 ried on for .3 consecutive seasons at 51 centers. 



The fertilizing ingredient producing the largest weight of crop was nitrogen. 

 Equally good results were secure<l from nitrate of soda and sulphate of 

 ammonia, and the best results from a mixture of the two. The largest appli- 

 cations of nitrogen gave the heaviest crops and the best financial returns. The 

 results secured indicate that the following application per acre is most likely 

 to give general satisfaction : i cwt. of 05 per cent pure nitrate of soda, S cwt. 

 of 05 i)er cent pure sulphate of ammonia. 2^ cwt. of 30 per cent soluble super- 

 phosphate and i cwt. of 55 per cent pure sulphate of potash. 



Irrigation of meadows, Stouolski {Ah.s. in Zhur. Oi>uitn. Apron. [Russ. Jour. 

 Eipt. Landir.\. S tl!H)7). Xo. 1. pp. 78, 79). — It is recommended that meadows 

 be irrigated in the fall when the drainage and river waters are especially rich 

 in fertilizing material, and it is stated that irrigation in the spring and summer, 

 which merely supplies the plants with moisture, should be done during the night 

 or on cool cloudy days in order to avoid injurious effects of sudden changes of 

 temperature. Irrigation of meadows is sometimes practiced during the winter 

 to destroy moss and weeds.
