552-579; ahs. in Ztschr. Immunitdtsf. u. Expt. Ther., II, Rcf., 5 {1911), No. 4, 

 pp. 061, 962). — Pi-eviously noted from another source (E. S. R., 26, p. 785). 



In regard to immunizing against hog cholera and swine plague, H. Prinz 

 {Ztschr. Infektionskraiik. u. llyg. Ilanstieie, 11 {1912), Xo. 2, pp. 125-152; 

 abs. in Berlin. Tierarztl. Wchnschr., 28 {1912), No. 11, p. 299).— After making 

 an examination of a number of cases of swine plague in young pigs the author 

 concludes that the work of Loffler and Schiitz does not determine the etiology 

 of this disease. For combating it, he recommends extreme hygienic measures, 

 protective vaccination occupying only a secondary place. 



The etiology of hog cholera seems to have been worked out In this disease 

 protective vaccination is of great importance. The protective and curative 

 action is the best when a composite serum is employed. 



Combating swine plague by vaccinating pregnant hogs, F. Train {BerUn. 

 Tierarztl. Wchnschr., 28 {1912), No. 3, pp. J/o, 46). — By vaccinating 17 pregnant 

 hogs in infected stalls with polyvalent swine plague bacilliary extracts, pigs 

 were obtained free from the disease and went on so to maturity. Antiseptin 

 was used for 23 other animals. Of these 22 gave birth to sound litters and 3 

 others yielded pigs with exanthema, but without a cough. Three additional 

 animals which received antiseptin and antiserum simultaneously yielded sound 

 offspring. 



The results obtained by other workers with these preparations are included. 



On the chemistry and toxicology of ascarids, F. Fluey {Arch. Expt. Path, 

 u. Pharmakol., 67 {1912), No. 4-5, pp. 275-392).— The first part of this work 

 (pp. 275-338) deals with the chemisti'y, the second part (pp. 33&-392), with the 

 toxicology of ascarids. 



RURAL ENGINEERING. 



Fundamental principles in tile drainage, J. L. Parsons {Proc. Iowa Engin. 

 Soc, 23 {1911), pp. 30-38). — This is a paper read before the Iowa Engineering 

 Society, held at Des Moines, February 15-17, 1911. 



The essential features in planning a tile drainage system are pointed out and 

 discussed, among them the planning of grade lines, determining the sizes of 

 tile, and laying out and spacing laterals. 



The reclamation of Missouri lowlands for agricultural purposes, F. F. 

 Shafer {Colman's Rural World, 65 {1912), Nos. 17, p. 1; 18, p. 1; 19, p. i).— 

 The author briefly discusses some of the principal factors that should guide 

 an engineer in making plans for drainage improvement districts, among which 

 are climate, rainfall, topogi-aphy, watershed, vegetation, and soil character- 

 istics, and describes tile drainage and its benefits. 



Results of experiments made to determine the waste of water by culti- 

 vators in irrigating their fields during the 3 years 1907-10, W. B. Gordon 

 (Punjab Irrig. Branch Papers, No. 11, pt. 2 B, pp. 5). — The results of these 

 experiments show that the average cultivator in the Punjab in applying the 

 water to his fields wastes on an average at least 20 per cent of it. Dividing 

 the fields into compartments and insisting upon the water being delivered 

 separately into each compartment are advocated. 



[Problems relative to irrigation of fields], J. M. Pujador {Rev. Inst. Agr. 

 CataUn San Isidro, 61 {1912), No. 7, pp. 99-102, figs. 3).— Systems of field 

 irrigation are described, consisting essentially of motor-driven pressure pumps, 

 pipe or hose systems for conveying the water, and apparatus for sprinkling 

 and distributing the water over the fields. 



A kerosene motor for irrigation, R. Olney {Irrig. Age, 27 {1912), No. 6, 

 p. 218, figs. 2). — ^Attention is called to the use of kerosene motors for driving
