Practical irrigation in humid areas, B. Adams {Forestry mid Irrig., 9 {1903), 

 Kus. (J, ])j). 285-288, figx. 8 ; 7, pp. 34(i-35S, fign. 4). — This article gives somewhat

The management of water in Java, Y. Bkkxakd {Amenagement den eaux cL Java. 

 Parii: LIbralrie Poly technique, 1903, pp. SO, pU. lG,figH. 75). — A stndy of the Javan 

 system witli reference to applicability to Indo-China. Since the Javanese so largely 

 subsist on rice the report is substantially a treatise on rice irrigation. In the first 

 part the development of agricultural industries since 1602 id briefly traced and the 

 topograi)hy and other features of different parts of Java, the drainage basins, dams, 

 canals, ditches, etc., are described. Maps show the irrigation system in detail and 

 the nature and extent of the area irrigated. The second part deals with technical 

 hydraulic and engineering details of construction and management of dams of vari- 

 ous kinds, canals, aqueducts, siphons, weirs, etc. The third part is devoted to the 

 actual distribution of water in rice culture. 



Government control is briefly discussed. The water is distributed gratuitously, 

 the government being reimlmrsed l)y the tax on the crop. When works now in 

 progress are completed the government will be able to irrigate 775,000 hectares 

 (1,914,250 acres) of land. This has been done at an expense of 300 to 400 francs per 

 hectare (S24 to So2 per acre). 



The restoration of the ancient irrigation works on the Tigris or the recre- 

 ation of Chaldea, W. Willcocks {Cairo: National Printing Dept., 1903, pp. 71, 

 ph. 10). — The author describes these works, especially the Nahrwan Canal, and dis- 

 cusses their restoration. Appendixes give monthly summaries of observations on 

 temperature, pressure, rainfall, and wind movement at Bagdad during 1888, 1894, 

 1899-1902, and an address on Egypt 50 years hence. 



The new directorate of agricultural hydraulics and improvement, L. 

 MouGEOT {Jour. Ayr. I^rat., n. ser., 5 {1903), No. 6, )>p. 183-187). — The report, 

 decrees, and regulations regarding the establishment of this directorate are given

Notes on the floods of February 28 to March 5, 1902; effect of proposed 

 drainage works on Passaic floods, C. C. VERMErLE ( Geol. Survey New Jersey Rpt. 

 1902, pp. 27-57, ])h. 7). — A study of the causes and conditions of these floods, with 

 a discussion of means of controlling such floods by means of storage reservoirs, 

 drainage, etc. 



First annual report of the State board of public roads of Rhode Island 

 {Providence, R. J.: E. i. Freeman it <SV».s% 1903, pp.32, map 1).^— This is the first 

 report of the board appointed under authority of an act of the State legislature passed 

 in January, 1902, and deals with present conditions, needs, etc., of Rhode Island 

 highways, and presents a classification of the "main or principal highways of the 

 State" with recommendations of the sections to be first constructed. "The length 

 of these particular sections makes a total of 20 miles, and the estimated cost for the 

 proper improvement of the same amounts to §100,000, an average of S5,000 per mile. 

 The estimate in each case provides for the construction of a macadam road of a 

 standard width of 14 ft., exclusive of shoulders and gutters, with a varying thickness 

 of crushed stone from 6 to 9 in., according to the location of the road, the nature of 

 the soil, the amount and weight of traffic, and includes drainage and grading. . . . 

 For the present year the board recommends an appropriation of $100,000, to be fol- 

 lowed by an annual increased appropriation of $25,000 for 3 years; and for the fifth 

 and sixth year an appropriation equal to that made for the fourth year. By this 

 plan of graded appropriations the whole work could be completed within a period of 

 6 years."
