Rats may be controlled to some extent by the use of infectious virus and 

 poisoned baits and by the mongoose. The nests of white ants are qiiite easily 

 destroyed by the use of hisulphid of earl)on. 



Insects in the coniferous forests of Vosges in 1906, dk Gail (Rer. Eaux 

 et Forets. Jj6 (1901), No. 6. pp. IGl-lG.'i). — A careful survey of this region was 

 made to determine the extent of infestation of coniferous trees with various 

 species of bark beetles and weevils. The results are stated in a tabular form. 

 It is believed that in such work frequent reconnaissances are desirable. Trees 

 found to be infested should be immediately cut and the bark removed. 



A homemade and effective insect trap, J. D. Evans (Canad. Ent., 39 {1901), 

 No. 5, PI). 150-1 ')2. fif/. 1 ) . — The author has had excellent success in catching 

 insects for collections from the use of a simple trap. This consists of a paper 

 funnel in which an incandescent light is suspended and which opens below into 

 a glass jar containing cynnid of ])otasli. 



A new method of preparing arsenate of lead, L. Degrully {Pro(j. Agr. et 

 Vit. (Ed. VEst), 28 (1901), No. 16. pp. ^62, 46.3).— On account of his inability 

 to obtain acetate of lead ui»on the market, the author used nitrate of lead for 

 the preparation of arsenate of lead by combination with arsenate of soda. For 

 this purpose, good results were obtained when 0.5 kg. arsenate of soda in 5 liters 

 of water was added to 1.2 kg. nitrate of lead in 5 liters of water. 



Annual report of the Bee-Keepers' Association of the Province of Ontario, 

 1906 (AiiH. Rpt. Bcc-Kccpcrs' Assoc. OiiUtrio. 1906. pp. 6''/). — In this report a 

 record is given of the proceedings of the twenty-seventh annual convention of 

 the Ontario Bee-Keepers' Association held in Toronto, November 7-9, 1906. The 

 discussions at the various sessions were largely of a practical nature and con- 

 cerned chiefly the production and marketing of honey. The essential points in 

 the production of comb honey were discussed by U. H. Bowen (pp. 14-16). The 

 matter of inspection for foul brood received considerable attention, and a copy 

 is given of the Ontario Act for the suppression of this disease. 



Short accounts were also presented of beekeeping as an occupation for women, 

 apiary appliances, retailing honey, fall management of bees, etc. 



The classification, biology, and distribution of the honeybee, H. von 

 BuTTELREEPEN (Mitt. Zool. Miis. Berlin. 3 (1906). No. 2. pp. 111-201. figs. 8).— 

 The present monograph on the honeyl)ee includes a discussion of the original 

 home of the honeybee and its relatives, the instincts of bees, the systematic 

 I'elationship of the honeybee and other species, and an elaborate account of the 

 biology of bees. The literature of the subject is discussed in connection with a 

 bibliography of 140 titles. Analytical tables are presented for the identification 

 of varieties of bees related to the honeybee, and descriptions are given of the 

 common races of the honeybee and other species of bees known to be of possible 

 value for the collection of honey. 



Bearing queens, E. Giraud (ApicuUeur, 51 (1901). No. }, pp. 151-163, figs. 

 4). — A description is given of the form and characters of the natural cell in 

 which queens are reared, and attention is called to the importance of rearing 

 queens at home in order to be sure of the breeding and to save expense. The 

 author describes and illustrates practical methods by which queen cells may be 

 started and the worker bees induced to supply these cells with royal jelly for the 

 development of the queens. 



Amount of -water necessary for bees, G. Gendot (ApicuUeur, 51 (1901), No. 

 4, pp. 16.'i-168). — Statistical data are presented relating to the quantity of water 

 required by bees under various conditions. According to the observation of 

 the author and other investigators, it ajiitears that bees need from ^ to i kg. of 

 water daily per colony. It is desirable, therefore, that attention be given to
