16 EXPERIMENT STATION RECORD. 



" Tbe impurities, in the form of suspended matter, consist of soot, tar, sand, 

 mineral substances, and, in solution, of suli)liurous and suipluiric acids or their 

 salts, chlorids, largely in the form of hydrochloric acid or common salt, and 

 nitrogenous matter, in the form of nitrates or free and albuminoid, matter." 

 Injurious effects of these substances on vegetation are discussed. 



Water: Its origin and use, W. Coles-Finch (London, 1908, pp. 506; rev. 

 ■in Chcm. Notes, 9!) {1909), No. 2565, p. //8). — This book treats in an elementary 

 way of the water of the atmosphere, rain, snow, ice, springs, and wells. Some 

 account is given of different methods of obtaining water, sinking wells, the con- 

 struction of waterworks, and the preparation of water for domestic use. The 

 use of water for irrigation and for operating hydraulic machines is also briefly 

 discussed. 



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

 Mexico, 1907-8, M. R. Hall and R. II. Bolster {U. S. Geol. Survey, Water- 

 Suppli/ Paper No. 2Jf2, pp. 226, pis. 3, fig. 1). — This is part 2 of a series of bul- 

 letins on the Surface Water Supply of the United States, 1907-8, and gives the 

 results of measurements of flow of streams in the drainage basins of the fol- 

 lowing South Atlantic and eastern Gulf of Mexico streams : James, Roanoke, 

 Yadkin or Pedee, Santee, Savannah, Ogeechee, Altamaha, Satillo, St. Johns, 

 Peace, Withlacoochee, Suwanee, Ocklockonee, Apalachicola, Choctawha tehee, 

 Escambia, Mobile, Pascagoula, and Pearl rivers. 



UnHergTound water resources of Connecticut; a study of the occurrence 

 of water in crystalline rocks, H. E. Gregory and E. E. Ellis ( U. 8. Geol. 

 Survey, Water-Supply Paper No. 232, pp. 200, pis. 5, figs. 31). — This bulletin 

 treats in some detail of the geography and geology of Connecticut; the occur- 

 rence and recovery of ground water ; ground water in crystalline rocks, triassic 

 sandstone and traps, and glacial drift ; the water supply of typical areas ; the 

 general character of ground water in Connecticut ; well construction ; and 

 springs. 



A bibliography of literature bearing on the subject is also given. 



Geology and underground waters of South Dakota, N. H. Daeton (U. 8. 

 Geol. Survey, Water-Supply Paper No. 221, pp. 156, pis. 15, figs. 7). — "This 

 report is intended mainly to set forth the geologic conditions bearing on the 

 occurrence of artesian waters in South Dakota. It comprises a description of 

 the sedimentary rocks, a statement as to the results of all the deep borings 

 which have been reported, and predictions as to the probable depths and area 

 of flow of the deeper-seated waters in all portions of the State. The water 

 resources for shallow wells are not considered except in areas where such 

 waters afford flows." Suggestions are given regarding the construction and 

 management of artesian wells. 



Farm water supplies of Minnesota, K. F. Kellerman and H. A. Whit- 

 taker (U. S. Dept. Agr., Bur. Plant Indus. Bui. 15 '^ pp. 87, figs. 73). — This 

 bulletin discusses briefly the increasing danger of pollution of water supplies 

 with increasing population, classifies farm water supplies with reference to 

 factors of pollution, describes the methods of collection and examination of 

 water supplies used in the investigations reported, and gives a detailed account 

 of' the particular water supplies examined, including dug, boi'ed, drilled, and 

 driven wells, springs, rivers, surface reservoirs, and cisterns. The rural 

 typhoid fever problem is also dealt with. The scope of the investigations was 

 limited to a single State but covered a wide range of rural conditions. The 

 results of the investigations are briefly summarized as follows : 



" Both farm and city are suffering from the careless management of rural 

 sanitation.
