all cases, but was subject to some disadvantages as compared with anilin milk. 

 The latter preparation is made by adding anilin oil to water in the proportion of 

 1 : IT). The mixture in then S])ra.ved or jtainted on the cracks and walls of the 

 granary and the fumes produced exercise a fatal effect upon insects for a long 

 time thereafter. The author states that it is i)erfec-tly safe for human beings to 

 work for a period of '1 iiours in the fumes produced from such treatment, init 

 that a longer period might cause nervous disturbances or other signs of 

 ])oisoning. 



The brown-tail moth and how to control it, Ij. O. Howard ( L\ (S'. Dcpt. 

 .\<ir.. Fanners' Bill 26'/, pp. 22. figs. Id). — A general account is presented of the 

 introduction, distribution, appearance, and life history of the brown-tail moth 

 with particular reference to injury to forest and other trees and the effect pro- 

 duced by the barbed hairs of the caterpillars upon the skin of human beings. 



Among the natural enemies of this pest a number of birds are mentioned, 

 Iiarticularly cuckoos, orioles, vireos, and l)lue jays. Native parasites are known 

 to attack them and recently an effort has been made to introduce European para- 

 sites. It is too early to predict the results of this importation. 



In combating the pest by artificial remedies the best residts follow the prac 

 tice of destroying the caterpillars in their winter nests. These webs or nests 

 may be readily observed as soon as the leaves fall and should be removed before 

 the caterpillars again become active in the spring. If this is not done resort 

 should be had to arsenate of lead or Paris green. The essential features of the 

 recent Massachusetts hiw regarding the brown-tail moth are given. 



Codling' moth and fruit fly, A. H. Benson {Queensland Agr. Jour.. 11 

 I lUini). So. S. pp. ]')o-l')7). — While the codling moth is not excessively injuri- 

 ous in Queensland, it is generally distributed throughout the colony, and the; 

 author believes that it can not be eradicated. For controlling the pest a destruc- 

 tion of infested fruit and spraying with arsenicals are recommended. 



It is believed that the control of the fruit fly can only be accomplished 

 by gi'owing the best varieties of fruit which will pay for the expenditure of 

 time and energy in their care. All infested fruit must then be gathered and 

 destroyed. 



Two important scale insects and their control, W. T. Clarke { Alabama 

 College Sta. ('ire. 1. pp. s). — Attention is called to the increasing development 

 of the fruit industry in Alabama and to the injuries caused to this industry 

 liy the Han Jose scale and the new peach scale. 



The same method of attack is available for both of these pests. For this 

 purpose the author reconunends the use of lime-sulphur-salt wash prepared 

 according to the fornnila 30-20-5-()0. 



A new Retinia attacking Austrian pine, A. Cosens {Canad. Eut., 38 

 {WOi)). \ii. II. pp. .i62-3(l'f). — Retinia diisfriana is described as a new species. 

 The insect is said to attack Austrian i)ine by Inirrowing in the cortical layer 

 of the tree and thus piercing the resin ducts and causing an exudation of gum. 

 The injury to infested trees is quite serious, although the pest is partly con- 

 trolled by parasites.

 ance and habits of various species of M()n()i)hlebns. PalL'Pococcus, Icerya, and
