Water resources of the Kennebec River basin, Maine; quality of Kennebec 

 River water, H. K. Barrows and G. C. Whipple ( U. S. Geol. Survey, Water- 

 SuppUl oiii Irrig. Paper ^o. 198, pp. F/+ 235, pis. 7, figs. 17). — "A large amount 

 of information of value in the study of this drainage basin has been gathered 

 at various times, but much of it is scattered through various manuscripts and 

 reports and is not readily accessible. This paper has been prepared in response 

 to the constant demand for this information from both engineers and the public. 

 Especial attention has been given to the subject of water storage, as this is of 

 the utmost importance to present and future users of the water and the natural 

 opportunities for regulating and improving flow in this basin are exceptionally 

 good." The investigations reported were made in 1904 to 1906 in cooperation 

 with the Maine State Survey Commission. 



Surface water supply of New England, 1906, H. K. Barrows et al. (U. 8. 

 Geol. Siirrei/. Water-Supplij (i)i(l Irrig. Paper Xo. 201, pp. 120, pis. 5, figs. 2). — 

 The observations reported in this bulletin are similar to those previously pub- 

 lished as reports on the progress of stream measurements. The methods em- 

 ployed in making the measurements are briefly explained and records of stream 

 flow in the principal drainage areas of New England are given. 



Occurrence and use of artesian and other underground water, E. H. Sel- 

 lards (Florida Sta. Bid. N9, pp. 8-')-113, map 1). — This is a preliminary report 

 on the water resources of Florida based upon investigations made in connection 

 with the U. S. Geological Survey and also independently by the Florida Station. 

 \ general account of the water supj)ly is given and its usefulness for agricultural 

 and other purposes is indicated. 



The results show that Florida is abundantly supplied with water and that 

 underground water of good quality is available for irrigating purposes in all 

 j)arts of the State. Surface water occurs at varying depths in limited quantity, 

 but artesian water occurs in abundant supply at greater depths. Flowing arte- 

 sian wells occur along the coast and at very low inland elevations. The surface 

 water is in imminent danger of contamination and ground water in limestone 

 is also in more or less danger of contamination from natural sinks and from 

 sewage wells. The undei'ground waters carry considerable amounts of mineral 

 matter in solution, but not enough to impair their usefulness for agricultural 

 l)nrposes. 



Underground water in Sanpete and central Sevier valleys, Utah, G. B. 

 RiciiARDsox (['. aS'. GcoJ. Survey, Water-Supply and Irrig. Paper No. 199, pp. 

 6S-\-yi, pis. 6, figs. 5). — This paper reports and discusses the results of observa- 

 tions on the soui'ce. distribution, i-ecovery, and quality of the imdergrouud 

 waters of these valleys. The data secured indicate that there is a considerable 

 supply of underground water awaiting development in the valleys. 



The composition of the waters varies with the geology of the watershed. 

 The waters of wells of the uplands are similar in composition to that of the 

 mountain streams of the same locality, but that from shallow wells in the low- 

 lands, especially in irrigated districts, usually contains a large amount of dis- 

 solved salts. " The natural conditions are generally favorable for obtaining good 

 water for domestic purposes, but the connnunities give little heed to the sanitary 

 character of the water, and as a result epidemics of typhoid fever of greater 

 or less violence are not uncommon."
