622 EXPERIMENT STATION RECOBD. 



and thence around the shore to Apponaug." The soils of this district 

 are with few exceptions comparatively level and naturally poor and 

 sandy. They are also frecjuently acid. An anah^sis of a sample of 

 the soil collected near Greenwood is reported, which indicates that 

 there is "a great need of most, if not all, of the kinds of plant food 

 which are liable to be lacking in soils." Plat experiments with fer- 

 tilizers on table beets and nuiskmelons at 2 places in the AVarwick 

 Plain and pot experiments at the station with Imrley on soil from one 

 of these localities are reported, with a discussion of the needs of the 

 soils and the best means of their improvement. AVhile the soils are 

 deficient in all of the principal elements of plant food, potash is appar- 

 ently less needed than either phosphoric acid or nitrogen. ''Lime is 

 probabh' needed as plant food, and particularly to overcome the aciditj^ 

 of the soil." Small applications of lime which has been exposed to 

 the air for a long time are recommended, as well as the stocking of 

 the soil with humus by the growing of leguminous plants for green 

 manure.

Analyses of soils, C. F. Juritz {Rpt. Senior Analyst, Cape Good Hope, 1899, pp. 

 41-71, map 1, dgms. 3). — This is an account of the work on the systematic soil survey 

 of the Cape of Good Hope to the end of 1899. This work has been rejiorted on from 

 time to time and noted in the Record (E. S. R., 12, p. 122). 



Soil investigations of the Tokay w^ine regions, B. vox Bitt6 {Landir. ]'ers.

 of examinations, mainly with reference to content of calcium carbonate of the soils 

 of this region, undertaken with a view to determining their adaptability to the 

 American grape. 



The rational analysis of clays from the agricultural point of view, E. 

 Vax dex Bkoeck {Bui. Soc. Beige Geol., U {1900), No. 3, pp. 161-166). — This is a 

 discussion of the results of analyses of samples of Tertiary clay from the vicinity of 

 Brabant by the hydrofluoric acid method proposed by A. Proost, which, it is claimed, 

 affords a truer index of the fertilizing constituents of the soil available for the use of 

 l)lants tlian the (mlinary method using hydrnchlnric acid. 



Investigations on the potash in cultivated soils, C. Disserre {Ann. Agr

 the hydrofluoric acid method than of the hydrochloric acid method in determining 

 the reserve potash of the soil, and tests of the relative action of different fertilizers
