410 EXPERIMENT STATION RECORD. 



Blood parasites, O. Malm (Norsk Vet. Tidsskr., 16 {1904), No. 4, pp. 81-92, 

 fn'x. 4). — A review is given of blood parasites belonging to the group protozoa, particu- 

 larly the malarial organism, and its relation to mosquitoes. 



Animal parasitology, M. Neveu-Lemaibe (Parasitologic animate. Paris: F. B. 

 di Rudeval, 1904, 2. ed., pp. 220, figs. 301 ).— A discussion is presented of tbe habits, 

 We history, and economic importance of animal organisms which are in anyway 

 injurious to man. These parasites belong to 9 natural orders of the animal kingdom 

 particularly to Vermes and Arthropoda. The habits, life history, and injurious 

 effects of each species are briefly noted with reference to methods of combating them. 



AGRICULTURAL ENGINEERING. 



Preparing land for irrigation and methods of applying water ( U. S. Dept. 

 Ayr., Office of Experiment Stations Bui. 145, pp. 84, pis. 7, figs. 33). — "The purpose of 

 tl is bulletin is to bring together the results of actual experience in preparing land 

 for irrigation, for the benefit of farmers who are now irrigating or who may in the 

 future undertake the reclamation of lands now arid. The information contained in 

 this report as to the tools and implements used, the methods to be employed, and 

 the cost of the work is based on actual examples and affords a reliable guide to the 

 cost of these features of irrigation in the districts represented, while the number and 

 wide distribution of these districts will make possible approximate estimates of the 

 cost of the different methods and will help greatly in the selection of the one best 

 suited to given conditions." 



The general discussion and comparison of methods of preparing land for irrigation 

 described in this bulletin, the descriptions of furrow irrigation, the check system of 

 irrigation, the use of flumes and pipes in furrow irrigation, the basin method of irri- 

 gation as practiced in the Santa Clara Valley, California, and irrigation by flooding 

 as practiced in Gallatin Valley, Montana, were prepared by S. Fortier. 



The use of metal pipe and canvas hose in the irrigation of field crops in California 

 is described by A. P. Stover; preparing land for irrigation in Salt Lake Basin, by 

 E. R. Morgan and A. P. Stover; the clearing and leveling of land in Imperial Valley, 

 California, by J. E. Roadhouse; irrigation by the furrow system in Washington, by 

 C. G. Elliott; irrigation practice in Nevada, by G. H. True; while methods of pre- 

 paring land for irrigation in use in western Kansas, in Nebraska, and in Wyoming 

 are described by L. G. C. Mayer, O. V. P. Stout, and William Francis Bartlett. 



Professor Fortier and R. P. Teele, editorial assistant in this Office, edited and 

 ar ranged the report for publication. 



Report on drainage investigations, 1903, C. G. Elliott ( U. S. Dept. Agr., 

 Office of Experiment Stations Bui. 147, pp. 62, pis. 5, figs. 12). — This report covers the 

 first year's work in drainage investigations by this Office. It explains the impor- 

 tance of drainage in the United States and describes plans which have been made 

 and put in operation "for reclaiming alkali lands at Fresno, Cal., in Yakima and 

 Atanum valleys, Washington, and in Grey Bull Valley, Wyoming; plans for the 

 drainage of overflowed bottom lands in the Missouri Valley in Iowa; and experi- 

 ments with the use of drains to prevent hillside erosion in Georgia." 



Sanitary conditions in the home and on the farm, H. Metcalf (South Caro- 

 lina Sta. Bui. 89, pp. SI, figs. 9). — This is a popular bulletin on sanitation. The 

 topics discussed are the dangers of dust, school-room sanitation, sewage disposal, 

 disinfectants, water supply, milk, food, and the dangers from insects. 



Current wheels: Their use in lifting water for irrigation (U. S. Dept. 

 Ai/r-, Office of Experiment Stations Bui. 146, pp. 38, pis. 4, figs. 21). — This bulletin 

 contains a discussion of the theory of current wheels, and descriptions, photographs,
