[Local variation of rainfall in the counties of Dublin, Wicklow, Kildare, 

 and Meath, Ireland], W. J. Lyons {ScL Proc. Roy. Dithlin Hoc, n. sci:, 12 

 {1910), No. 30, pp. 354-373, map 1). — Summarizing the available rainfall records 

 for this region, the author finds a clearly defined dependence of the distribution 

 of the rainfall on the marked configuration of the country, the rainfall increasing 

 with the elevation, with tbe slope as distinct from the height of the elevated 

 area, with the position of the slope with reference to the direction of the wind, 

 and with the extent of the sea or evaporating area over which tbe wind has 

 previously passed. 



A study of rain frequency indicated " that tbe great differences observed in 

 annual rainfall over a limited area are generally not due to rain days being 

 more frequent in the mountains tban in tbe low-lyiug districts, but rather to 

 the rain being more intense, or possibly more prolonged in the course of each 

 rain day." 



Water powers of the Cascade Range. — I, Southern Washington, J. C. 

 Stevens ( U. S. Geol. Survey, Water-Supply Paper No. 253, pp. 91t, pis. 21, figs. 

 3). — This bulletin is the first of a proposed series dealing with the water ix)wers 

 of tbe streams flowing from the Cascade Range in Wasbington and Oregon, and 

 gives tbe results of measurements and estimates of water power in the drain- 

 age basins of the Klickitat, White Salmon, Little White Salmon, Lewis, and 

 Toutle rivers. 



Surface water supply of the South Atlantic coast and eastern Gulf of 

 Mexico, 1909, M. R. Hall and R. H. Bolster (U. 8. Oeol. Survey, Water- 

 Supply Paper No. 262, pp. 150, pis. 5). — This is one of the series of papers on 

 the surface water supply of the United States, and contains results of flow 

 measurements on the principal streams of the South Atlantic and eastern Gulf 

 of Mexico drainage systems. 



Surface water supply of the St. Lawrence River basin, 1909, C. C. Covert, 

 A. H. HoRTON, and R. IT. Bolster (U. S. Geol. Survey, Water-Supply Paper No. 

 261f, pp. 130, pis. 5). — Tbis is one of the series of papers on the surface water 

 supply of tbe United States and gives the results of flow measurements of 

 streams in tbe St. Lawrence River basin. 



The underground waters of north-central Indiana, S. R. Capps and R. B. 

 Dole (U. 8. Oeol. Survey, Water-Supply Paper No. 254, PP- 279, pis. 7, figs. 

 12). — This paper reiwrts a study of conditions met in endeavoring to obtain 

 supplies of underground water over an area of 7,611 square miles in north- 

 central Indiana. Tbe geograpby and general geology of the region are also 

 described. " The conditions in 378 cities, towns, and villages were investigated, 

 and a considerable amount of work was done in tbe country districts between 

 these communities. Especial attention was paid to tbe water conditions in 

 communities having public supplies. . . . More or less complete records of 

 about 1,200 wells were procured. ... In all, S3 areas in which flowing wells 

 occur were visited and their outlines mapped." 



It is stated that there are few places in the area investigated where enough 

 water for domestic purposes can not be obtained at moderate depths. " Difli- 

 culties are often met, however, in obtaining wells of sufficient yield for public 

 supplies or for manufacturing purposes where large quantities of water are 

 needed." 



Recommendations are made as to possible improvements wbere public water 

 supplies are inadequate or sbow bad sanitary conditions. 



Wells furnish most of tbe water for drinking and for general domestic pur- 

 poses in this region of Indiana. Many of these well waters contain so much 

 free hydrogen sulpbid that they are unfit for use. They also as a rule contain 

 a high percentage of chlorids, but this is not due to animal pollution. The
