On the alkali soils of Middle Hungary, A. von Sigmond (Wiener Landw. 

 Ztff., 5.') (WO.'j), /j/>. (Lis, (Ui); ub.s. in Zciitbl. Agr. Chem., 30 (1901), .Yo. 2, pp. 

 133, 134). — The origin and character of these soils are discussed. 



Notes on some Java soils, W. Detmeb and II. Immendorff (Botanische und 

 landicirtschaftliciic Studicn auf Java. .Jena: Gustav Fischer, 1907, pp. 26- 

 36). — Chemical analyses and clay content of samples of soil and subsoil from 

 cacao, cinchona, and tea plantations are compared with analyses of representa- 

 tive German soils. The most notable feature of these analyses is the high 

 percentage of fertilizing constituents In the (good) tea soil (0..50 per cent of 

 nitrogen, O.IG per cent of phosphoric acid, 0.24 per cent of potash, and 0.66 

 per cent of lime). 



Soils of Cambridgeshire, F. \V. Foreman (Jour. Agr. Sci., 2 (1907), No. 2, 

 pp. 1(11-182). — Physical and chemical analyses of typical soils of this district 

 are reported. These analyses show in general a close relation between the 

 mechanical and chemical character of the soils and the underlying formations. 



Analyses of soils from old apple orchards, A. L. Knisely (Oregon Sta. 

 Rpt. 1905, pp. 65, 66). — Analyses of samples of soil from old orchards and 

 from adjacent fields, made with a view to determining whether the failure 

 of such orchards is due to exhaustion of potash, are reported. The results 

 show that the average potash content of the orchard soils (0.22 per cent) was 

 not materially different from that of the adjacent fields (0.23 per cent). The 

 author, therefore, concludes that " the stunted growth, lack of vigor, etc., are 

 due much more to neglect than to a deficiency of plant food in the soil." 



Soils of the Abitibi district, R. Harcoubt (Ann. Rpt. Ontario Agr. Col. 

 and E.rpt. Farm, 32 (1906). pp. 58-62). — Analyses ai-e reported of 18 samples of 

 soil from this region, which occupies that part of the districts of Algoma and 

 Nipissing lying between latitudes 49 and .51° N. 



The results show that none of the soils are likely to be deficient in lime and 

 most of them are abundantly supplied with it. The larger proportion of the 

 soils is well supplied with potash and phosphoric acid. The nitrogen content Is. 

 as a I'ule, very low for soils which have never been cropped. The humus con-
