880 EXPERIMENT STATION RECORD. 



" From these organisms a mixed infection vaccine was made containing ap- 

 proximately the following dosage per cubic centimeter : Streptococcus 50,000,000, 

 8. aureus 100,000,000, and B. ahortivus equinus 100,000,000. The initial dose 

 varied from 0.5 to 1 cc. according to the age and condition of the foal. The 

 dosage rarely produced any local and never any general reaction. The results 

 obtained were very satisfactory." 



The vaccine was distributed free to veterinarians, and a total of 170 case 

 reports were received. The mortality in this group was 25 per cent, whereas 

 the average mortality in the Province of Ontario is 66 per cent. 



Porage poisoning' in horses and mules, R. Geaham, L. R. Himmelbergeb, 

 and R. L. Pontins (Wallaces' Farmer, JfO {1915), No. 36, p. 1147, figs. ^).— The 

 authors report upon investigations conducted during the course of a serious 

 outbreak of forage poisoning in Kentucky. Experimental animals were placed 

 upon a farm where a total loss of $2,000 in horses and mules that had fed 

 on corn and oat hay had occurred. One of two horses was fed upon nothing 

 but suspected corn, the other nothing but suspected oat hay. The horse which 

 was fed upon oat hay contracted and died from the disease. The disease was 

 also produced by feeding oat grain from the oat hay in question and by feed- 

 ing the oat straw. 



The authors state that they have been unable to transmit the disease from 

 sick to healthy animals by blood injections, but they were able to produce it at 

 will by feeding the oat hay. 



Diseases of poultry, B. F. Katopp {North Carolina Sta. Bui. 233 {1915), pp. 

 3-27, figs. 9). — A popular discussion in which the subject is dealt with under 

 the headings of external parasites, internal parasites, and contagious diseases. 

 This is followed by an account of the internal anatomy of. the fowl, including 

 a description of the proper way to open and examine the fowl after death. 



RURAL ENGINEERING. 



The place and field of the agricultural engineer, R. S. Shaw ( Trans. Amer. 

 Soc. Agr. Engin., 8 {1914), PP- 11-18). — The author is of the opinion that the 

 agricultural engineer should be in close cooperation with the agriculturist so 

 that the engineering principles involved in the work of the former may be made 

 of practical value to the latter. "Agriculture and engineering have always been 

 interdependent, the latter paving the way for the development of the former, 

 which in turn continues to stimulate and sustain the development of the latter." 



The place and field of the agricult^^ral engineer, A. Maeston {Trans. Amer. 

 Soc. Agr. Engin., 8 {1914), pp. 19-26). — The author feels that in addition to the 

 fields of salaried and consulting agricultural engineering there is a broader 

 field for the agricultural engineer in contracting for agricultural structures and 

 in the invention, manufacture, and sale of farm machinery and general agricul- 

 tural equipment. 



Surface water supply of Snake River basin, 1912 (Z7. S. Oeol. Survey, 

 Water-Supply Paper 332-B {1915), pp. 278). — This report, prepared in coopera- 

 tion with the States of Idaho and Oregon, presents the results of measurements 

 of flow made on streams in the Snake River basin in 1912. 



Surface water supply of lower Columbia River and Rogue, Umpqua, 

 Wilson, and Nehalem rivers, 1913 {U. 8. Oeol. Survey Water-Supply Paper 

 S62-C {1915), pp. 246). — This report, prepared in cooperation with the States 

 of Oregon and Washington, presents the results of measurements of flow made 

 on these rivers in 1913. 



Deschutes project, J. T. Whistler, E. G. Hopson, and J. H. Lewis {Oreg. 

 Cooper. Worlc, Dept. Int, U, 8, Reclamation Serv., 1914, Dec, pp. 147, pis. 69).^
