Eighteenth annual report of the Reclamation Service, 1918-19, A. P. 



Davis (Ann. /?/#. Reclamation Serv, [U. S.], 18 (1919), pp. 559, figs. 2).— This 

 repoi't covers the work of the U. S. Reclamation Service completed and in 

 progress during the fiscal year ended June 30, 1919. 



It is stated that during the present year the service is in a position to de- 

 liver water to about 1.600,000 acres of irrigable land covered by the crop 

 census, of which about 1,120,000 are now being irrigated. Besides this, storage 

 water is delivered from permanent reservoirs under special contracts to about 

 950,000 acres more. The projects that have been undertaken have been 

 planned to provide for an area of about 3,200,000 acres. 



Use of water on Reclamation Service projects, E. A. Mokitz (Reclam. Rec. 

 [U. /S.], 11 {1920), No. 3, pp. 128-lSO).— Tables of data showing quantities of 

 water used on projects of the U. S. Reclamation Service by months during 1918 

 are given. 



Drainage as an anti-malaria measure, J. A. Leprince (Amer. Jour. Pub. 

 Health, 10 {1920), No. 2, pp. 120-123) .—The author argues the necessity of lib- 

 eral interpretation of laws, urges the cooperation of the liealth officer in drain- 

 age planning, and suggests the value of permanent improvements following a 

 study of local conditions. 



Louisiana State highways, C. M. Kerr {Proc. La. Engin. Soc, 1 {1915), No. 

 4. pp. 178-196, pis. 5). — The author briefly discusses the Louisiana State High- 

 way Act and reviews expenditures and activities of the Highway Department. 



The evolution of the public roads problem in the Province of Quebec, 

 A. Fkasek {Jour. Engin. Inst. Canada, 3 {1920), No. 3, pp. 135-141. fig. i).— This 

 article deals with the historical development of the roads administration in 

 Quebec, Government roads policy and progress of public roads improvement 

 during the last 15 years, and the present organization of the engineering stafE 

 of the Provincial Roads Department and its work. 



[Foundation types for country roads] {West. Highways Builder, 2 {1920), 

 No. 4, PP- 5, 21, figs. 4)- — Types of foundations in common use for country roads 

 are discussed by the Bureau of Public Roads of the U. S. Department of Agri- 

 culture. 



Relation of highways to motor truck operating cost, A. H. Blanchard 

 {Engin. and Contract., 53 {1920), No. 9, pp. 238-240). — A discussion is given of 

 the relation of highways to motor truck operating cost, which indicates that the 

 probable cost of transport over highways outside of municipalities is not suscep- 

 tible of an exact mathematical analysis. It is stated, however, that there is 

 sufficient information from the combined experience of English and American 

 highway authors to permit the drawing of certain general conclusions which 

 will either warrant the installation or positive rejection of highway transport 

 business. This is considered specially true on the basis that the installation of 

 highway transport in a given community should not depend upon a narrow 

 margin of profit. 



Laboratory tests of granite paving block and suggested specifications, 

 F. H. Jackson, jr. (Engin. and Contract., 53 (1920), No. 9, pp. 234-237, figs. 

 2). — Tests for granite paving block in present use are discussed, and experiments 

 on granite block testing conducted by the Bureau of Public Roads of the U. S. 

 Department of Agriculture, are reported. 



The conclusions are drawn that none of the laboratory tests which have been 

 used for tes mT granite block may be depended upon to give even reasonably 

 concordant re.sults. It v/as found that the abrasion test may be so modified as
