A test of drainage, A. H. Rosenfeld {Rev. Indus, y Agr. TucumAn, 5 {1915), 

 No. 9, pp. 369-371). — Deep ditch drainage of sugar cane soil was found to 

 increase tlie yield of sugar cane | tons per liectare (about 670 lbs. per acre) 

 over that from undrained, but deeply plowed, cane soil. 



Note on the level of the water in the subsoil of the Gangetic plain, E. A. 

 Maloxy {Dcpt. Land Rec. and Agr, United Prov. Agra and Oudh, Agr. Ser., 

 Bui. 33 {1915), pp. 9). — The factors affecting ground-water level are discussed, 

 with particular reference to the Gangetic plain. 



It is pointed out that an appreciable lowering of the ground-water level in 

 that locality caused by excessive run-off, evaporation, moisture utilization by 

 vegetation, or other factors may seriously diminish or completely cut off the 

 supply of water of wells in places where much dependence is placed upon the 

 well water for irrigation or other purposes. In order to maintain the ground- 

 water level it is considered necessary to increase the capacity of the lakes and 

 swamps which catch the rainfall and so permit some of the water held back to 

 percolate into the subsoil, and to open up a more rapid communication between 

 the surface and subsoil reservoirs. 



The farm water supply, O. M. Kile {W. Ya. Col. Agr. Ext. Dcpt. C'irc. 43 

 (1915), pp. 15, figs. 12). — This circular outlines briefly simple methods of im- 

 proving the various kinds of farm water supplies, and describes several simple 

 water-.supply systems now in u.se on West Virginia farms. 



Annual irrigation revenue report of the Government of Bengal for the 

 year 1913-14 {Ann. Irrig. Rei\ Rpt. Bengal, 1913-14, pp. 11+101, pis. 9).— 

 This reports the physical and financial condition of irrigation works in Bengal 

 and describes Irrigation activities for the year irtl.3-14. 



Elements of highway engineering, A. H. Blanch ard {Xew York: John 

 Wiley d Sont, 1915, pp. XII +51 4, figs. ^02).— This book, intended for the u.se 

 of engineering student.'*, consists of original matter and of material from a 

 previous book by the author and H. B. Drowne (E. S. R., 30, p. 289) "which 

 has been revised and remodelled to meet the requirements of a book suitable 

 for use by engineering students. . . . Each chapter has been written with a 

 view to emphasizing the fundamental principles which have been evolved from 

 past experience as well as from the modern practice of highway engineering 

 which, as a science and an art, is rapidly developing in the fields of economics, 

 administration, legislation, materials, and methods." 



The.ch.npters included ai'e as follows: Economics, administration, legislation, 

 and organization; preliminary investigations: surveying, mapping, and design; 

 grading, drainage, and foundations; earth and sand-day roads; gravel roads; 

 broken stone roads; bituminous materials: dust prevention and bituminous 

 surfaces; bituminous macadam pavements; bitumiuous concrete pavements: 

 sheet asphalt and rock asphalt pavements; cement-concrete pavements: wood 

 block pavements; brick pavements; stone block pavements; street cleaning and 

 snow removal; comparison of roads and pavements; sidewalks, curbs, and 

 gutters; and highway structures. 



Thi-ee appendixes giving a glossary of terms applicable to highway engineer- 

 ing and describing in detail methods for dotorniining physical and chemical 

 properties of bituminous and nonbituminous highway materials are also 

 included. 



Brick monolithic construction of county highways, R. L. Bell {Engin. and 

 Contract., 44 {1915), No. 14, pp. 26S-270, figs. 9).— The construction of a brick 

 pnvement having a concrete base and a brick wearing surface is describetl, in 

 which " the brick are placed directly on the concrete while it is still green so 

 that to all intents and purposes the road is made up of one solid slab." The 

 advantages of this type of brick pavement are stated as follows: "(1) A better
