ether, flowers of pyrethrnm, and a luixture of these flowers and the root of valerian 

 (.sold under the name "zanzolina" ). The draming of stagnant pools and the appli- 

 cation of kerosene to the surface of water in which mosquito larvai are found are dis- 

 cussed . 



Mosquito brigades and how to organize them, R. Ross (Xew Vnrk:- Lmu/nunts, 

 <;m'n& Co., 190:2, pp. 100).— A general account is given of the habits and life history 

 oi different species of mosquitoes, with special reference to tlie locations in which the 

 larvic are found. The author outlines in detail a system of organized effort for the 

 destruction of mosquitoes in and near towns. The scheme embraces the collection 

 and removal of tin cans, broken bottles, and other receptacles in wliich water might 

 be collected and mosquito larvic might occur. Especial attention is to be given to the 

 drainage of pools and small ponds of stagnant water in which mosquitoes are known 

 to breed. It is urged that in towns where mosquitoes occur in large numbers organ- 

 ized effort should be put forth to combat them according to approved methods. A 

 superintendent, who should preferably be a medical or sanitary oflicer, is to be 

 assisted by a number of workmen, and the men are to visit all premises in the town 

 at regular intervals for the purpose of preventing the extensive })reeding of mosqui- 

 toes. It is not hoped that these efforts will be successful in exterminating mosipiitoes, 

 even in a limited area, but it is believed that their numbers may be gi-eatly reduced. 

 The author reviews the more important literature on the sul)ject and gives biblio- 

 graphical references to the chief works on mosquitoes. 



Insects beneficial to horticulturists, J. S. Hine {I'roc. Columhm Horl. Soc, 16 

 ( 1901 ), No. 1, pp. :i6~29). — Brief notes on the relationship of predaceous and parasitic 

 insects to horticulture. 



Report of the lecture on apiculture, H. R. Eowsome {Ontario Agr. Col. <md 

 E.ipt. Fann Rpt. 1901, pp. 125, 1-26). — It was found that by placing queens in an 

 inverted glass carboy ami then introducing drones the desired cross could easily be 

 secured. Much difhculty has been experienced hei-etofore in (-(jntrolling the fertili- 

 zation of queens. Brief notes are also given on the economy in the utilization of jiar- 

 tially tilled sections in feeding the'm back to the swarms. 



Bee culture, G. W. "Williams {Missouri State Ed. Agr. Rpt. 1900, pp. 71-81). — Brief 

 notes on the various processes connected with raising bees, including the general sys- 

 tem of management, wintering, and bee pasture The author claims to have obtained 

 profitable returns from the cultivation of certain bee plants exclusively for honey 

 These plants included Simpson's honey plant, cure-all, and fig wort. 



A simple fixed frame and an improved bottom board, H. R. STEPnE\s( Queens- 

 land Agr. Jour., 9 {1901), Xo. 6, p. 556). — Brief descrii>tive notes on 2 cheap and 

 convenient devices for use in beehives. 



Annual report of the Royal Sericultural Station at Padua {Ann. R. Staz. 

 Bacol. I'adoca, 29 {1900), pp. 12,1, pi. 1). — This rejtort contains a number of articles 

 relating to sericulture, among which the following may be mentioned: The work of 

 the Royal Sericultural Station for the year 1900, E. Verson (pp. 5-11) ; The organi- 

 zation of markets for silkworm cocoons in Italy, E. Verson (pp. 15-40 and 97-104); 

 Armature of the prolegs of the silkworm larv;e, E. Verson (pp. 41-()5); A disease 

 of spinners and rearers of the silkworm, E. Quajat (j>p. 66-70); Rapid and gradual 

 incubation, E. (.2uajat (j)p. 77-84); Influence of the time of washing the eggs upon 

 hatching in the spring, and upon accidental hatching in autumn, E. (^uajat (pji. 85- 

 89); Creohn in the silk industry, E. Verson (pp. 90-96). It was found that the 

 vapor of creolin unifonnly exercises a poisonous influence on the eggs of the silk- 

 worm. The mortality in the eggs may vary from 4 to 100 j>er cent, according to the 

 length oi time during which they are exposed to creolin. .\ bibliography of literature 

 relatnig to sericulture which appeared iu 1900 and 1901 is appended to the report.
