" Several different grades of abaca are recognized in the market, the differ- 

 ences being due chiefly to greater or less care in cleaning the fiber, and there- 

 fore this fiber presents a wide variation in v^eight per meter and in strength. 

 The highest and lowest figures given in the foregoing table do not represent the 

 extreme limits. Henequen and sisal cleaned by machinery are more uniform." 



METEOEOLOGY— WATEE. 



The org-anization of a meteorological service for agriculture, P. Bkoounoff 

 {Quelques Considerations sur VOrganisation du Service Meteorologlque dans Ic^ 

 iuts de VAgrictilturc. St. Petersburg, 1912, pp.12). — This is a brief statement 

 based largely upon considerations which controlled in the organization of the 

 bureau of agricultural meteorology in Russia. 



Notes on the meteorological bureau and the scientific committee of the 

 agricultural ministry of Russia, P. Beoounoff {Quelques Donnees svr le 

 Bureau Metcorologique du Comity Soientifique du Ministdre de VAgriculture. 

 [St. Petersburg, 1912], pp. 7). — This pamphlet gives a brief history of the 

 organization and development of the bureau of agricultural meteorology of 

 Russia. 



Meteorological observations by the Hamburg observatory in Bergedorf, 

 1910 and 1911, R. Schoer (Jahrb. Hamburg. Wiss. Anst.. 29 (1911). Beiheft 5, 

 pp. X-^93, pis. 3). — Tabular summaries are given of observations during the 

 period named on pressure, air and soil temperature, humidity, precipitation, 

 wind movement, and sunshine. 



Bulletin of the Mount Weather Observatory (U. S. Dept. Agr., Bui. Mount 

 Weather Observ., 5 (1913), pt. 5, pp. 295-364, pi. 1, figs, ii).— This number 

 contains the following articles : The Effect of the Atmospheric Turbidity of 

 1912 on Solar Radiation Intensities and Skylight Polarization (illus), by 

 H. H. Kimball; The Haze of the Upper Atmosphere, by R. O. E. Davis; 

 Dynamic Meteorology, by H. Bateman; and Elementary Problems in Meteorol- 

 ogy, Second Series (illus.), by C. F. von Herrmann. 



Relation of meteorological study to more logical systems of cropping and 

 to crop production, J. F. Vookhf;es (Proc. Soc. Prom. Agr. Sci., 33 (1912), pp. 

 87-101, figs. 8). — This article points out how more intensive and efiicient sys- 

 tems of farming may be secured by adapting them more perfectly to the cli- 

 matic conditions. A plea is also made for wide cooperation in the systematic 

 study of this problem. 



Agricultural crops and the weather, P. Beoounoff (Les Cultures Agricoles 

 et le Temps. St. Petersburg, 1912, pp. JfJ^, figs. 23). — This pamphlet discusses 

 the adaptation of cropping systems to climatic conditions. It describes the 

 character and distribution of agricultural meteorological stations in Russia 

 and summarizes some of the more important results of the investigations car- 

 ried on by these stations, especially with reference to the climatic adaptation 

 of various crops. 



The influence of the moon en the weather, G. Wagner (Gerlands Bcitr. 

 Geophijsik, 12 (1913), No. 2, pp. 27 7 -32 S) .—This is a review of the histoi-y and 

 present status of popular belief and scientific opinion regarding the relation 

 of the moon to the weather. 



Snow surveys for predicting stream flows, J. C. Alter (Engin. News, 69 

 (1913), No. 22, pp. 1110-1113, figs. 10; Irrig. Age, 28 (1913), No. 7, pp. 210, 

 211, figs. 4). — This article describes the instruments and methods used and 

 results obtained in the surveys made by the U. S. Weather Bureau of snowfall 

 in the Wasatch Mountains near Springville, Utah, for the purpose of securing 

 a basis for predicting the summer flow of Maple Creek. See also a previous
