Some common niainm.al3 of western Montana in relation to agriculture 

 and spotted fever, C. Birdseye {U. S. Dcpt. Agr., Farmers' Bui. 48), pp. 46, 

 figs. 34)- — This bulletin is based on investigations conducted in western Montana 

 for several years, especially in the Bitter Boot Valley, in cooperation with the 

 Bureau of Entomology of this Department and with the Montana Station. A 

 circular relating to the subject has been previously noted (E. S. R., 25, p. 756). 



The author concludes that the most feasible ways of controlling Rocky Moun- 

 tain spotted fever, which is transmitted from wild animals to human beings by 

 the bite of infected ticks, are : "(1) To etlucate the inhabitants of infested locali- 

 ties in a belief in the 'tick theory; ' (2) to lessen the number of wood ticks, by 



(a) keeping domestic stock, the principal hosts of the adult ticks, tick free and 



(b) lessening the number of native rodents, the necessary hosts of the younger 

 states of the ticks; and (3) to destroy those native rodents which may serve as 

 a source of continued reinfection of the ticks." 



Directions for jwisoning and otherwise destroying rodents are presented. 



Analysis of the results of 87 fecal examinations of sheep dogs for evi- 

 dences of parasitism, W. D. Foster (Science, n. ser., 35 {1912), No. 901, pp. 

 553, 55-'i)- — This is a brief statement of the results of examinations of collie and 

 sheep dogs imported to this country, made while in quarantine. 



All the dogs examined that were found to be infested with tapeworms were 

 given a suitable tseniafuge. Of 87 dogs examined, 50 were infested with para- 

 sitic w!Orms, and of these 28 were infested with nematodes only, while the 

 remainder were infested with tapeworms of 1 or more species or of tapeworms 

 and nematodes. Of the 22 dogs infested with tapeworms, 7 were infested with 

 Tcvnia hi/datigcna, 8 with T. pisifoi-mis. 4 with DipyUdium caninum, 2 with 

 Hiulticcps scriaJis, and S with unidentified Trenia. 



The author is inclined to believe that the small percentage of infestation 

 shown in the examination is the result of the greater care bestowed on valuable 

 animals. 



A new species of trematode from the muskrat, Fiber zibethicus, F. D. 

 Barker and J. W. Laughlin (Trans. Amcr. Micros. Sac, 30 (1911), No. J/, pp. 

 261-274, pi. 1). — The tremato<le here describetl as Notocotyle quinqueserialc n. 

 sp., is one of a large number of trematodes, representing several species, that

Microbes killing mice and rats, A. Yoytkevich and A. Kolenev (Viestnib 

 Balct. Agron. Stants'ii V. K. FerrcJn, 1911, No. 18, pp. 97-153). — An extended 

 discussion of the sul^ject. 



Raticide — Azoa, S. S. Mereshkowsky (CentU. Bakt. [etc.l, 1. Ait., Orig., 

 62 (1912), No. 1-2, pp. 72-75). — The author's investigations led him to con- 

 clude that the commercial preparation known in England by the name Raticide 

 and in America as Azoa can not be reconnnended for use in destroying rats. 



The food of birds of India, C. "W. Mason and H. Maxwell-Lefroy (Mem. 

 Dcpt. Agr. India, Ent. Scr., 3 (1912), Jan., pp. 371). — This paper is said to be 

 a compilation from various sources of what little is known of the food of 

 Indian birds at the present time. It also contains numerous field notes on the 

 food of the common species of the plains, together with the records of 1,325 

 stomachs examined in the laboratory.
