Irrigation with fresh water from the sea, E. J. Moynihan (Sci. Amer. Sup., 

 79 {1915), No. 2040, pp. 84, 85). — The author proposes the use of sea water 

 for irrigation purposes and maintains that its distillation to remove the in- 

 jurious salts is practicable. 



He describes two methods of procedure, the first of which is based on the fact 

 that the temperature of sea water varies considerably with the depth and 

 that probably " for those months in the year in which water is most needed 

 there are suitable places near shore where a temperature difference of 5° exists 

 in very moderate depths of water . . . Under these conditions it is easy to 

 evaporate the water at the higher, and to condense it at the lower, temperature. 



" The second metliod of distilling tlie water consists of increasing the pressure 

 and therefore raising tbe temperature of the distilled vapor or the water to be 

 distilled by mechanical means, such as a compressor turbine, and condensing 

 the vapor in a surface condenser, the condensation water being the same water 

 that is being evaporated. In this way the whole of the latent heat of con- 

 densation is returned to the water which is being condensed."

West Tennessee gullied lands and their reclamation, R. S. Maddox {Re- 

 sources Tenn., 5 {1915), No. 1, pp. 8-22, figs. 3).— This article deals with an 

 area of more or less eroded and gullied lands lying in a belt extending in a 

 northeast and southwest direction through the State, and which is practically 

 contained in the counties of Henry, Benton, Carroll, Henderson, Madison, Ches- 

 ter, McNairy, Hardeman, and Fayette. 



It is stated that in this area more than 115,000 acres of land once cultivated 

 are now occupied or influenced by gullies and that over 230,000 acres once 

 cleared and cultivated are lying waste. The soil in this belt is very sandy and 

 in some localities is mixed with enough clay to make it subject to easy erosion. 



For starting the reclamation of these lands the author recommends the plant- 

 ing in gullies of such quickly-growing and widely-rooting trees as the black 

 locust, yellow poplar, black walnut, and sycamore, and such crops as Japan 

 clover, wild honeysuckle, and Bermuda grass. All these are said to be particu-
