this method. The Zehetmayr modification of this system consists of sowing in 

 furrows which are later filled in around the plants instead of transplanting. 



Although the author's work with wheat in India along these lines was 

 destroyed by ants, he says that corn planted in furrows about 5 in. deep gave 

 about If times as great yields as that sown on the level. 



Earthing up was also tested for somewhat similar purposes, but gave lower 

 results than deep transplantation. 



The Demtschinsky hilling' method, N. Demtschinsky (Deut. Landw. Prcsse, 

 38 (1911), No. 25, p. 293, fig. i).— The author outlines the Chinese method of 

 hilling small grains for moisture conservation and the development of the 

 root system. He recommends an implement manufactured in Magdeburg with 

 which a man and horse can hill from 6 to 7 hectares (14.82 to 17.29 acres) of 

 grain per day. 



Insuring increased yields — the theory and practice of the Demtschinsky 

 methods for growing' small grains, N. A. and B. N. Demtschinsky [Die 

 Verviel fa Chung und SicherstcUimg der Ernteertrdgc, Thcorie iind Praxis der 

 Ackerhectlailtur. Berlin, 1909, pp. 116, pis. 12, figs. 10). — A discussion of the 

 theory underlying the authors' new methods is followed by directions for their 

 use in grain growing and a statement of the results of tests and observations 

 at Torbino and of other tests of transplanting and hilling methods. 



[Tests of the Demtschinsky method], G. Bohutignsky (IUus. Landw. Ztg., 

 31 {1911-), Nos. 3, pp. 13, U; 5, pp. 29-31, figs. 3).— The author summarizes the 

 results of exjieriments with winter wheat, winter barley, and oats conducted in 

 1909-10. Tables state in detail the results obtained by the ordinary method, 

 and the deep sowing, hilling, and Zehetmayr modifications of the Demtschinsky 

 method. 



From the data presented the author concludes that hilling produces a greater 

 production per plant which may compensate for the loss due to thinner seeding. 

 The use of the Demtschinsliy methcKl prolonged the vegetation period by from 

 3 to 8 days, but increased the danger from rust. The new methods gave a 

 higher yield per plant but not per acre than the ordinary method. The deep 

 planting method gave negative results. 



Tests of the new grain cultural methods of Demtschinsky and Zehetmayr, 

 O. Lemmermann et al. {Landw. Jahrh., .'/l {1911), .A'o. 2, pp. 163-256). — These 

 tests were conducted at Hohenheim on the experiment fields of the Royal Agi'i- 

 cultural High School of W iirt ember g. The author states in tables the results 

 obtained since 1908 in work with winter rye, barley, wheat, and oats, as well 

 as with some summer varieties. 



From the data presented he concludes that thin sowing resulted in unusutil 

 tillering, but no marked difference api>eared in the tillering of grains that were 

 hilled or planted more deeply than usual. The use of the Zehetmayr method 

 resulted in tillering about midway between that following the Demtschinsky 

 and the ordinary methods. Tillering was most affected in case of winter barley, 

 less so in case of winter rye and winter wheat, and least of all in case of 

 summer barley. 



Both methods apparently retarded ripening by from 3 to 10 days. The 

 Demtschinsky method resulted in a greater retardation than did the Zehetmayr, 

 but if the plants were more deeply set later a more regular development of the 

 straw, and therefore a more regular ripening of the grain, was attaiued than 

 if this work were left undone. The Demtschinsky method more effectively 

 prevented lodging, the Zehetmayr method accomplishing this to a lesser degree. 



The grain and straw yields per plant were effectively raised by the Demt- 

 schinsky method as compared with the ordinary method, especially in case of 

 winter barley. The Zehetmayr method gave results midway between. The
