760 EXPERIMENT STATION EECOED. 



to establish tlie fact that the red spider is blowu sufficient distances by the 

 wind to make an infested orchard a menace to orchards within a reasonable 

 distance. Experiments are briefly reported. 



Rocky Mountain spotted fever.— A report of its investigation and of 

 work in tick eradication for its control during 1913, L. D. Ericks {Pub. 

 Health Rpts. [U. S.], 20 (Wl/,), No. S, pp. JtJ,9-m) .—The author reports upon 

 tick eradication, particularly as relates to domestic animals, including the 

 construction of dipping vats; and also upon the destruction of wild animals, 

 tick surveys, sheep grazing, and the investigation of the geographical distribu- 

 tion of Rocky [Mountain spotted fever. 



FOODS— HUMAN liTUTRITION. 



The milling quality of Marquis wheat, C. H. Bailey ( Minnesota Sta. Bui. 

 137 {1914), pp. 9-14, fig. 1). — Comparison was made of the yield of flour, pro- 

 tein content, and bread making quality of middlings flour from samples of 

 Fife, Bluestem, and Marquis wheat grown in the same locality. 



The conclusion is reached that " the Marquis wheat samples tested were 

 slightly superior in most respects to the Fife and Bluestem samples raised 

 under the same conditions. A higher yield of total flour was obtained from 

 the Marquis samples and the high-grade or 'middlings flour' contained a higher 

 percentage of protein, absorbed more water in making the dough, and produced 

 loaves of somewhat greater volume. There was comparatively little difference 

 in the color of flour obtained from the two groups of wheat." 



The soy bean and its use as a foodstuff {Konserv. Ztg., 14 {1913), No. 48, 

 pp. 377, 378). — A brief account of the history, nutritive value, and utilization of 

 the soy bean. 



Graphic representation of the value of milk, A. J. J. Yandevelde {Bui. Soc. 

 Chim. Belg., 27 {1913), No. 11, pp. 287-295, figs. S).— Believing that the dangers 

 of adulterated milk can be best brought home to the public by graphic repre- 

 sentations, the author has worked out and here publishes the mathematical 

 formulas for constructing circular diagrams in which the nutrients and adul- 

 terants of milk may be strikingly shown. 



Report to the local government board upon the availablgs data in regard 

 to the value of boiled milk as a food for infants and young animals, Janet 

 E. Lane-Claypon {Rpts. Local Govt. Bd. [Gt. Bnt.], Put). Health and Med. 

 SuJjjs., n. ser., No. 63 {1912), pp. 60, figs. 5). — This report includes an exhaus- 

 tive summary of the reliable investigations into the relative values of human 

 and other milks, both raw and boiled, for infant feeding, and also detailed ref- 

 erence to a research carried on by Ballin with healthy babies at the Infant Con- 

 sultation of the Naunyn Strasse in Berlin. Numerous statistics of growth and 

 similar data are given in connection with the Berlin work. The author's sum- 

 mary and conclusions, based on both experimental and clinical data, are as 

 follows : 



" There is apparently no serious loss of nutritive value produced by feeding 

 an animal upon boiled milk derived from an animal of the same species. At 

 the same time it must be pointed out that the pubMshed evidence on this point 

 is scanty. 



" When an animal is fed upon the milk of another species, the milk from 

 which has been found to be suitable for this purpose, such small differences as 

 have been found in the nutritive values of raw and boiled milk have been in 

 favor of boiled milk. 



"The milk of the same species has a considerably higher nutritive value for 

 that speeies than the milk of any other species so far investigated.
