38 EXPERIMENT STATION EECOED. 



Wheat — Variety tests, N. Schmitz (Marylmid 8ta. Bid. IJfl, pp. SS-JfO).— 

 Earlier variety tests have already been noted (E. S. R., 11, p. 440). 



The tests here reported were made on poorly drained clay loam fertilized with 

 400 lbs. per acre of a 9-2-5 fertilizer. Fultz was used as the standard for com- 

 parison of varieties and as a check against soil variations. During 8 years of 

 the period 1899-1907, Currell Prolific, Dietz, and New Shanghai averaged 33.6, 

 31, and 30.7 bu. per acre respectively. In a test of 39 varieties only Bearded 

 Purple Straw, Dietz Longberry, and China averaged more than 30 bu. per acre 

 for the period 1908-1910. 



Roumanian wheat. — Harvests of 1900-1908, A. Zaharia (Le B14 Ron- 

 main. — R^coltes des Annees 1900-1908. Bucharest, 1910, pp. 581, maps 10). — 

 Tables present data with regard to the wheat harvested by each of a large 

 number of farmers, including the area devoted to wheat, the average returns 

 per acre, the weight per hectoliter and per thousand grains, and the chemical 

 composition. 



HORTICULTUHE. 



Frost fighting-, A. B. Wollabeb (Mo. Weather Rev., 38 {1910), No. 7, pp. 

 1106, 1107). — This is an abstract of a paper by A. G. McAdie describing the 

 method of frost protection by means of small fires or heaters developed in Cali- 

 fornia and now followed elsewhere, the essential features of which are (1) 

 accurate advance information of the likelihood of frost, (2) application of pre- 

 ventive means during critical hours, and (3) guarding the fruit from a too 

 rapid warming. 



" In all the devices now on the market attention has been given simply to 

 the heating. Fuel of different kinds is used and for various crops there will be 

 a difference in efficiency, depending upon the fuel used, cost of labor, etc. 



" It seems to the writer that all protective devices are based upon the three 

 following principles: (1) Heating, (2) covering, (3) ventilating. Under the 

 first, come all forms of fire baskets, oil pots, and orchard heaters. Under the 

 second, cloth covers, lattice work, artificial cloud builders, smudge makers, and 

 the new anti-frost cover. Under the third head there should be devised suitable 

 forms of blowers and air mixers." 



Frost fighting in the Boise Valley, E. L. Wells (Mo. Weather Rev., 38 

 (1910), No. 7, pp. 1120, 1121). — Trials in an orchard near Boise of fire pots 

 burning oil are reported, the results indicating that " orchard heating in the 

 Boise Valley is entirely practicable, and by its intelligent use serious loss from 

 frost can be practically eliminated." 



Modern ideas over the reciprocal influence of stock and scion, A. Bencke 

 (Gartenwelt, Hi (1910), No. 23, pp. 269-272). — A review of recent experimental 

 knowledge relative to the mutual relation between stock and scion. 



Report of the Geisenheini Experiment Station for Pomology, Viticulture, 

 and Gardening for 1909, J. Wortmann et al. (Ber. K. Lehraiist. Wicn, Obst 

 u. Gartenbau Geisenheini, 1909, pp. 26^, figs. 49). — This report includes a gen- 

 eral review for the year of the instruction work in the Geisenheim Institute 

 and of the activities of the divisions of plant physiology, plant pathology, bio- 

 chemistry, pure yeast culture, meteorology, and forest diseases, together with a 

 report of the Geisenheim-Eibingen grape propagating station. 



Agricultural experiment, H. H. Cousins (Ann. Rpt. Dept. Agr. [Jamaica], 

 1910, pp. 6-9). — This consists of an outline report of cultural experiments in 

 Jamaica with sugar cane, coffee, bananas, citrus, mangoes, cocoa, cassava, to- 

 bacco, vanilla, and coconuts including reports on the growth of Para rubber 

 planted in different parts of Jamaica in 1906.
