14 EXPERIMENT STATION RECORD. 



The relation of meteorology to horticulture, K. H. Curtis (Jour. Roy. Hurt. 

 8()(: [Loiiddii], ,J3 (IHthS), .Vo. /. pp. /.i-/.'*) ■— This is a continuation of a pre- 

 vious article and deals cliieliy with atniosplieric moisture, particularly the 

 amount, distribution, and cliaracter of the rainfall in relation to plant growth. 



The development of the German weather service during 1907, Hornstein 

 {./alirh. J>(iil. Ijiiidir. (Icsdi.. 2J {HIOl), .Vo. -'/, />/>. 77; /-77;',).— This is a brief 

 statement regarding the value of this service to farmers. 



The weather of the summer of 1907 in Germany and its influence on the 

 agricultural industry, Kassner and Hillman {Jahrh. Dcut. Landiv. GeseU., 

 22 (1007), Xo. //, pp. 765-778, pis. //). — The season of 1007 is briefly discussed 

 from the meteorological standpoint as well as with reference to its influence 

 on the agricultural industry. 



Climate | of Belgium], {Expos6 dc la Situation du Royanmc de 1876 a 1900. 

 Brussels: Govt., 1907, vol. 1, pp. 55-S//).— The general climatic conditions are 

 descril)ed and meteorological obser\'ations which have been made since the 

 establishment of the observatory of Brussels in 1833 are summarized. 



Contributions to the study of the meteorology of Cape Verde, J. M. de 

 Macedo {Rev. Off MissCio Agron. Caho Verde, 1 (1908), Nos. 1, pp. 19-2Jt; 2, 

 pp. 48-51; ,3, pp. 85-88). — The meteorological conditions during 1905-1907 are 

 briefly sunmiarized. 



Studies on the climate of Tunis, G. Ginestous (Etudes sur le climat de la 

 Ttiiiisie. Tunis, 1906, pp. -'i28+Xl, illiis.; rev. in Bui. Dir. Agr. Com. et Colon. 

 [Tunis], 11 (1907), No. 1/5, p. 577). — This is a thesis presented for a doctor's 

 degree at the University of Taris. It reviews previous iniblieations on the 

 climate of Tunis and summarizes and discusses the meteorological data obtained 

 at the various stations of the meteorological service of Tunis during more than 

 20 years. The work is in three parts, (1) general character of the climate of 

 Tunis, (2) study of the climate of Tunis, and (3) natural climatic regions of 

 Tunis. 



The climate of Sao Paulo, Brazil, F. T. de Souza Reis (Lavoura; Bol. Soc. 

 Nac. Agr. [Brazil], 11 ( 1907), Ko. 9, pp. 393-399.— This is a brief review of the 

 Itrincipal meteorological elements for this region. 



Lakes and forests as climatic factors, J. Schubert (Geogr. Ztschr., 13 

 (1907), No. 12, pp. 688-694, flO- !)• — Observations bearing on this subject are 

 reviewed with an attempt to explain the climatic influence exerted by lakes and 

 forests. 



A new theory of formation of underground w^ater, G. Martinet (Chron. 

 Agr. Vaud, 21 (1908), No. 1, pp. 13-16). — The author agrees with Haedicke that 

 in many cases at least atmospheric precipitation is not sutflcient to maintain the 

 underground supply of water, and that in such cases the supply is maintained 

 more largely by absorjttion of aqueous vapor from the air than from precipitation. 



Iron in subterranean waters, H. Schwers (Rev. Hyg. et Pol. Sanit., 30 

 (1908), Nos. 1, pp. Il-'i3, flg. 1 ; 2, pp. 100-126, figs. 8; 3, pp. 185-221 ; .'/, pp. 287- 

 306). — This is a rather comprehensive discussion of this subject divided into 

 general and special parts. The flrst part deals with the nature of iron com- 

 pounds in subterranean waters, the conditions which cause their solution, and 

 the processes of removal of the iron. The second part deals particularly with 

 a study of natural ferruginous deposits (ochers), and tests of methods of re- 

 moving iron, witli practical conclusions arrived at. 



Water-supply investigations in Alaska, 1906-7, F. F. Henshaw and C. C. 

 Covert (V. S. Geol. Survey, Water-Supply Paper 218, pp. 156, pis. 12, figs. 2).— 

 This report gives the results of stream measurements in the Nome and Kougarok 

 regions of the Seward Peninsula, and the Fairbanks district of the Yukon- 

 Tanana region, as well as meteorological records (rainfall, temperature, and
