Meteorological observations, W. T. Ellis, R. Robertsox, S. A. Bedford, A. 

 Mackay, and T. A. Sharpe {Vauwhi Expt. Farms lipis. 1901, pp. 60, 61, 3S5-3S7, 455, 

 512, 558^. — A record of the continuation of ol)servations of previous years (E. 8. R., 

 13, p. 228) . 



Meteorological chart of the Great Lakes, A. J. Henry and N. B. Conger 

 ( \J. S. Dept. Agr., Weather Bureau, Meteorological Chart of the Great Lakes, 1902, No. 1, 

 pp. 26, charts 2). — This is a summary of data relating to the weather during the sea- 

 son of navigation; precipitation in the Lake region, winter of 1901-2; ice during 

 winter of 1901 and 1902; opening of general navigation, season of 1902; Avrecks and 

 casualties from January 1 to April 30, 1902; Lake region storm of April 25-26, 1902; 

 a new service by the Weather Bureau (predictions of high north to east winds at 

 Buffalo to raise the ice blockade), and the display of storm warnings on the Great 

 Lakes. 



Wind, velocity and fluctuations of water levels on Iiake Erie, A. J. Henry 

 ( r. *S'. Dept. Agr., Weather Bureau Bui. J, pp. 22, charts 25). — "This report deals 

 with the character and frequency of the storm winds that prevail on Lake Erie, the 

 changes in water level produced by them, and the possibility of predicting the occur- 

 rence of the most pronounced changes in level at the eastern end of the lake." 



A year of weather and trade in the United States, R. DeC. Ward {Pop. Sci. 

 Mo., 61 {1902), Xo. 5, pp. 4..VJ-448). — The conclusion reached by the author from 

 his study of this subject is that "as the result of the experience of many years, trade 

 is in a condition of such very close and delicate adjustment to the average weather 

 of any particular month, or even week, that 'seasonable,' i. e., normal weather, 

 other things being equal, usually means 'seasonable' trade. . . . When meteorolog- 

 ical conditions are unseasonable, trade at once reflects the change, and suffers. Trade 

 is, however, subject to many and widely varying controls; hence the problem of the 

 particular controls which affect it in any one week is a very complex one, and the 

 key is not always, or sometimes even at all, to be found in local weather conditions." 



Composition of Barbados rainfall {Rpt. Agr. TIorA-, Imp. Dept. Agr. West Indies, 

 1899-1901, p. 2). — The total amount and the chlorin and nitrogen (total and as 

 ammonia and nitrates) in the rainfall at Dodds Botanic Station for each month from 

 December, 1899, to May, 1901, inclusive, are reported. 



Rainfall at the Variety Experiment Stations from December, 1899, to 

 May, 1901 {Ilpl. Agr. Worl; Imp. Dept. Agr. West Indies, 1899-1901, pp. 142, 143).— 

 The nund)er of rainy days and number of inches of rainfall for each month during 

 this period are reported for 11 places in Barbados. 



A study on the climate of Tunis, (i. Ginestous {Bid. Dir. Agr. el Com. lTn)ris], 

 7 {1902), No. 24, pp. 251-363, Jigs. 4, charts 4). — This is the third connuunication 

 (E. S. R., 14, p. 16) on this subject and summarizes the available meteorological 

 data for the three summer months, June, July, and August. 



Ten years' observations on the influence of the weather on the yield of 

 sugar beets and on the so-called second growth of beets {Deut. Landw. Presse, 

 29 {1902), Nos. 53, pp. 452, 453; 54, p. 460). — A brief discussion based mainly on 

 Rimpau's observations and applicable to German weather conditions.
