The composition of some Herzegovinian and Macedonian soils, 

 W. BluSCH {ZUchr. L<nuhr. V,r.snrhs,r. OeMrrr., 3 {WOO), pp. 637-00',; 

 (/hs. Jn CIk^iii. C'riifhl., HKKK IL No. ':ih, p. /;2.fV).— M(M-hanical and 

 chemical analyses are reported of tobacco soils fiom these regions 

 undertaken with a view to determining- whether the ({uality of the 

 tobacco was d(»}iendent upon the character of the soil or of the ferti- 

 lizers used. The IIei'zeo()vinian soils were calcareous, but, with one 

 exception, pool' in calcium cari)()nate. The Macedonian soils were- 

 loamy. l)ut uniformly rich in calciuiu car])onate. The results indicate 

 that the brittleness of the Ilerzegovnnian tobacco after drying as coni- 

 paivd with the Macedoinan tol)acco can not l)e attributed to the abun- 

 dance of lime in the soil. (leneral suggestions regarding the fertilizing 

 of the soils are made. 



The geological agronomic charting of soils as a basis for their 

 general valuation, .1. Hazard {Landir. J<ilifJ>., 30 (JOOO)., No. 6., pp. 

 805-011, clidrfs 11). — The soils of certain areas in North Saxony are 

 charted on the l)asis of their observed adaptal)ility to the more impor- 

 tant crops and of their geological, petrographic, and physical exami- 

 nation. The methods employed are d(\scribed and the results obtained 

 are reported and discussed in detail. A close correlation was observed 

 between physical properties and adaptability to crops. The methods 

 followed are claimed to furnish a reliable basis for the valuation of 

 soils and for the selection of cr()[)s ])est suited to them. 



Subterranean waters, ('. Mokhis (JoKr. Fnirilclin In.^l., i.7i (l!)01), No. 3, pp. 

 18J-194, -figs. 2). — The origin, distrilmtion, and geological functions of subterranean 

 waters are discussed. 



Contribution to the study of subterranean waters, K. INIauboctix {Couipt. 

 Raid. Acad. Scl. Farw, 13£ {1901), No. 6, pp. S65-o(>8). — A brief account is given of 

 a study by means of fluorescein of the source and rate of circulation in the soil of 

 subterranean waters from wiiich the water supply of Paris is derived. 



The soils of Allegany County, C. W. Dorsfa' {Maryland Geulogicai Survri/, Allc- 

 ganii Countji. Baltimore: Jolivn Hopkins Press, 1900, pp. 195-316) . — This article dis- 

 cusses the forces which are active in' the formation and the fac-tors determining the 

 jM-oductive capacity of soils; briefly reviews previous work on the soils of the county, 

 including that of Whitney (E. 8. R., 4, p. 17; 5, p. 162), and describes 17 type soils 

 found in the county. Mechanical analyses of these type soils and subsoils are also 

 given. 



" The soils of Allegany County are so closely related to the geological formations 

 from which they are derived that a knowledge of the rock formations throws much 

 light ni)on the soils which are found there." The type soils described are therefore 

 given the names of the geological formations from which they are derived.
