distribution and migration of all the species of warblers numbering 59, together with 

 19 subspecies which are discussed. 



The yellowtail tomtit (Acanthiza chrysorrhoa), C. French (Jour. Dept. Agr. 

 Victoria, J (1904), No. 10, p. 1000, pi. 1). — Brief notes are presented on the habits of 

 this bird with especial reference to its efficiency as an insect destroyer.

 Stiles and A. Hassall ( U. S. Dept. Agr., Bureau of Animal Industry Bui. 39, pp. 

 511-S59). — In these parts of the index-catalogue a list of authors is given whose 

 names begin with (i. 



METEOROLOGY— CLIMATOLOGY. 



Weather and crops in Europe in 1904 (Jour. Bd. Agr. [London], 11 (1904), 

 No. 8, pp. 479-4S5). — A general review of weather conditions and crop production 

 during the season of 1904, calling attention especially to the fact that "the central 

 and southeastern countries of Europe suffered in a marked degree from drought and 

 extreme heat, and the crops, particularly maize, roots, potatoes, late hay, and fodder 

 crops, have in consequence been more or less injured, though it is probable that in 

 the case of the cereal crops there may be some compensation in the improved 

 quality of the grain." 



Main results of agricultural-meteorological observations on the Poltava 

 experiment field during the years 1886-1900, W. A. Vlasov (Zhur. Opuitn. 

 Agron. [Jour. Expt. Landw.], 5 (1904), No. 4, pp. 433-477).— The author reviews (1) 

 the yields for 15 years (1886-1900) on the Poltava experiment farm of winter rye, 

 winter and summer wheat, oats, and barley, and (2) the meteorological conditions 

 during the same years, and attempts to deduce some conclusions concerning the 

 influence of the local meteorological conditions on the yield of the cereals men- 

 tioned. — P. FIREMAN. 



Report of the meteorological work of the Ploti Agricultural Experiment 

 Station, M. Svolinsky (Godichnuil Otchet Ploty. Selsk. Khoz. Opuitn. Sktutzu, 9(1903), 

 pp. 1-25,121-124, charts2). — The usual observations on temperature of the air and the 

 soil, atmospheric pressure, humidity, precipitation (including snowfall), evaporation, 

 sunshine, solar radiation, wind movement, and miscellaneous phenomena are reported. 



Meteorological summary for 1903, H. Dufour and D. Valet (Chron. Agr. 

 Canton Vaud, 17 (1904), No. 17, pp. 495-508).— Observations at Lausanne, Switzer- 

 land, on temperature, precipitation, sunshine, and soil temperature are summarized 

 for each month of the year and compared with averages for previous years. 



Meteorology, P. Boname ( Rap. An. Sta. Agron. [Mauritius'], 1903, pp. 1-9).— Obser- 

 vations on atmospheric pressure, humidity, temperature, and rainfall are summarized 

 for each month of the year. In case of rainfall summaries showing daily, monthly, 

 and seasonal distribution are also given. The mean annual pressure was 736.7 mm. 

 (28.73 in.), varying from 727.1 mm. (28.36 in.) January 29 to 742.8 mm. (28.97 in. ) 

 July 26. The average temperature was 21.4° C, the maximum 30.5° in March, the 

 minimum 11° July 13 and September 9. The annual rainfall was 1,386.3 mm. 

 (54.5 in.) as against 1,736.5 mm. (68.22 in.) in 1902. Of this amount 712.4 mm. 

 (27.78 in.) fell during the night. Although the rainfall during 1903 was somewhat 

 below normal, its distribution was very favorable for crops. 



Forecasting the weather (Nat. Geogr. Mag., 15 (1904), No. 7, pp. 285-292, jigs. 

 7). — This article gives some generalizations applying to the United States east of the 

 Rocky Mountains, especially the Middle and Upper Mississippi and Ohio valleys, 

 the lake region, and the Middle States, which it is believed will enable the local 

 observer "to detect in the atmospheric changes, apparent to the eye or apprehended 

 by the sense of feeling, the coming of an area of cloud and precipitation with its 

 attendant whirling winds — warm on the front and right-hand side and cold in the 

 rear and on the left-hand side."
