18 EXPEKIMENT STATION RECOED. 



tory of Florida, with special reference to its underground water. The water 

 supply of euch county as well as of tlie State as a whole is discussed with 

 reference to its source, quality, and developmeut, and tables giving data for 

 typical wells of the State are added to many of the county descriptions. The 

 illustrations include a general topographic and geologic map of Florida, a map 

 of its Pleistocene terraces, a diagram showing the importance of ctoosiug proper 

 locations for wells, and half-tones showing features of geologic interest. 



Surface water supply of the Ohio River basin, 1911, A. H. Horton, M. R. 

 Hall, and H. J. Jackson ( U. 8. Geol. Survey, Water-Supply Paper SOS, 191S, pp. 

 112, pis. 4). — This paper reports results of measurements of flow made on the 

 Ohio River and its tributaries during 1911. Tables are also included giving 

 gage heights and daily and monthly discharges at each station. A comparison 

 of relative rates of run-off from different areas in this basin shows an almost 

 entire lack of uniformity or agreement between any two streams. 



The Ohio Valley flood of March- April, 1913, A. H. Hoeton and H. J. Jack- 

 son (U. aS'. Geol. Survey, Water-Supply Paper S34, 1913, pp. 96, pis. 22). — This 

 report contains available recent flood data from the Ohio River Valley, together 

 with facts concerning earlier floods, which are presented primarily for com- 

 parison with those concerning the flood of 1913. It is attempted to show what 

 can and should be done in collecting the data necessary for a complete report 

 on the floods in the Ohio Valley and emphasizes the necessity of immediately 

 starting, on a comprehensive scale, the collection of stream-flow data not only 

 from the Ohio itself but from its larger tributaries to the end that a definite 

 decision may be reached as to the best and most economical means of prevent- 

 ing damage by floods. 



Geology and water resources of Sulphur Spring- Valley, Ariz. {U. S. Geol. 

 Survey, Water-Supply Paper S20, 191S, pp. 1-187, 2U~231, pU. IJf, figs. 32).— 

 This work represents a cooperative investigation, between the United States 

 Geological Survey and the Arizona Experiment Station, of the ground waters 

 and possibilities of irrigation in the valley. 



The physiography and drainage; geology; rainfall; occurrence; level, and 

 quality of ground water; vegetation in relation to water and other geographic 

 controls ; and the artesian conditions of the valley are discussed in some detail 

 by O. E. Meinzer (pp. 1-187), together with an investigation of the concentra- 

 tion, distribution, and general effect of the alkalis in the soil and water. So- 

 dium carbonate is said to be the most harmful alkaline constituent in the soil, 

 and where the depth to water is less than 15 ft. the soil usually contains in- 

 jurious amounts of alkali, while where the depth is more than 15 ft. the soil 

 is usually free from injurious amounts. 



In addition there is a discussion by R. H. .Forbes (pp. 214-224) of the agri- 

 cultural resources of the valley, in which it is stated that di*y farming and flood 

 water farming are uncertain methods of culture there, while dry farming sup- 

 plemented with a pumped water supply is a more certain method. See also a 

 previous note (E. S. R., 29, p. 725). 



Ground water in Eoxelder and Tooele counties, Utah, E. Carpenter (U. S. 

 Geol. Survey, Water-Supply Paper 333, 1913, pp. 90, pis. 2, figs. 9).— The chief 

 purpose of this paper is to report an investigation made to determine the feasi- 

 bility of irrigating by use of underground water in this region, which includes 

 Boxelder and the eastern part of Tooele counties, Utah, and some small tracts 

 in southern Idaho. The physiography, geology, climate, vegetation, soil, and 

 Industrial development of the region are discussed in some detail and the 

 occurrence and quality of ground water supplies are taken up by areas, mainly 

 from the standpoint of their availability and use for irrigation purposes. In
