METEOROLOGY. 



Solar and terrestrial magnetism in their relations to meteor- 

 ology, F. II. 15k;hlo\v , r. 8. Dept. Ayr., Weather Bureau Bui. 21, pp. 

 176, charts 39). — This is a technical explanation of the author's theory 

 that the atmospheric; conditions which culminate in the storms travers- 

 ing the United States are in part dne to the direct magnetic action of 

 the sun upon the earth, in which an attempt is made to correlate the 

 observations bearing on this subject into general scientific laws. The 

 general topics treated are the relation between magnetism and meteor- 

 ology, the determination of the 26.68-day solar magnetic period, 

 analysis of the polar magnetic field along the terrestrial meridians, 

 deflecting forces of the equatorial electromagnetic field, some relations 

 between the terrestrial magnetic field and the meteorological elements, 

 and solar magnetism. 



Oklahoma weather and crops for 1897, G. E. Morrow (Oklahoma Sfa. Bui. SO, 

 pp. 12). — A general account of the soil, meteorological conditions, and agricultural 

 products of Oklahoma, with a record of temperature and rainfall iu 1897 as com- 

 pared with previous years at a number of places in the Territory. 



Meteorological observations, J. E. Ostrander and A. C. Moxahan (Massachu- 

 setts ITatch Sta. Met. Buls. 109, 110, 111, pp. 4 each). — These bulletins contain notes on 

 the weather and the usual summaries of meteorological observations during Jan- 

 uary, February, and March, 1898. 



Meteorological observations in Denmark, 1896-97 (Holt's Lommebog Landm., 

 lS98,pp. 88, 89). 



Fonstal meteorological studies, E. Hoppk (Centbl. Gesam.Forstw. Wien,24(lS9S), 

 No. 4, pp. 147-166). 



WATER— SOILS. 



The soils of Tennessee, 0. F. Vanderford (Tennessee Sta. Bui., 

 Vol. X, No. 3, pp. IV+31-139,fif/s. 37, maps 3). — This is a preliminary 

 report on a systematic survey of the soils of Tennessee, commenced 

 about 6 years ago. 



"It is not intended as a complete treatise on the subject. The station has a con- 

 siderable amount of material which must be reserved for future discussion. This 

 bulletin contains, after a description of the objects and methods of the survey, the 

 physical and chemical analyses and climatological and botanical relations of a 

 number of the most important typical soils of Tennessee. The notes made by the 

 agriculturist on the agricultural treatment of the soil have been pretty fully incor- 

 porated for the purpose of interesting the practical farmer. 



"The bulletin is accompanied by the preliminary soil map of the State, which 

 was compiled by the station, with the assistance of the United States Geological 

 Survey and the Division of Soils of the United States Department of Agriculture. 

 For the purposes of instruction and further study, this soil map has been put upon 

 a relief map of Tennessee 10 ft. 4 in. long by 2 ft. 10 iu. wide, which was prepared 

 by the station in cooperation with the United States Geological Survey. A half- 

 tone plate made from a photograph of this relief-map model is inserted in the 

 bulletin." 



Mechanical analyses by M. Whitney, of this Department, and chem- 

 ical analyses by J. B. McBryde of fifteen samples of soils (with, in some
