sequently to its issue, are now paid particular attention to, amongst these are the 

 Hessian Fly, Stem Eel-worms and the Wheat Bulb-iiy. The information concern- 

 ing all the attacks treated of in both editions has been largely augmented and 

 the special subjects of Wire worms, Turnip-llea-beetle, Mustard Beetle, and Hop 

 Aphis are entered on at length. 



Special attention has been given to the presentation of the latest developments 

 in the way of preventive measures. Attention is drawn to the use of chemical 

 manures which are highly beneficial as plant-stimulants (but by no means so to 

 vegetable-feeding grubs and maggots), and the many kinds of agricultural imple- 

 ments, by which the soil can be more completely broken up on the surface, or the 

 surface more thoroughly buried down than was formerly the case, these are of 

 great assistance to us. As an Appendix to the Manual is given a short and 

 copiously illustrated " Introduction to Entomology," where, in the plainest 

 possible language, the structure and changes of insects are described, and illustra- 

 tions and definitions of the various natural orders into which they are classified 

 are given, so as to " enable the observer of a crop attack to tell at least what kind 

 of insect is before him," and also " in the list of the orders of insects, notes are 

 given of the most observable of the characteristic points by which the insects 

 composing these different orders may be distinguished from each other." 



A glossary of terms and a full index render this work very complete. It 

 contains 410 pages, and is illustrated with 155 excellent figures, many of them 

 from the authoress's own pencil. The frontispiece is a portrait of the authoress 

 which has been prefixed by desire of many friends and will be of interest to many 

 in this country who have not had the pleasure of meeting Miss Ormerod. The 

 manual is well printed, neatly bound in cloth, and the small price at which it i& 

 published (SI. 25) brings it within the reach of all. 



There are many articles in the manual which are of interest to Canadian 

 readers as they describe insects which also occur here — amongst these the follow- 

 ing may be mentioned : 



The Bean Weevil (Bruchus granarius). — Treating the seed with a solution 

 of sulphate of copper and carbolic acid are recommended, also soaking the seed 

 beans for some time before they are sown, or dropping them for one minute inta 

 boiling water. 



The Cabbage Aphis (Aphis hrassicce). — In garden cultivation drenching the- 

 infested plant with soap-suds is practicable, syringing with an infusion of tobacco 

 in lime-water has been found useful and dusting • with caustic lime and soot are 

 stated to be very eflfective in getting rid of the aphis. 



The Small White Cabbage Butterfly (Pieris rapoe). — The greatest confi- 

 dence seems to be placed in strencrthening the plant, so as to enable it to outgrow 

 the attacks of the caterpillars. In this country this is insufficient and undoubtedly 

 the best remedy is pyre thrum powder reduced with 4 times its weight of 

 common flour or finely sifted lime and then dusted over the plants. 



Cabbage Fly (Anthomyia brassicce). — The use of barn-yard manure imme- 

 diately before a cabbage crop seems to induce attack, also the continuous culti- 

 vation of cabbages on the same ground. The value of lime and ashes are 

 emphasized by the experience of correspondents. 



Carrot Fly {Psila rosce). — This is an uncommon insect in Canada ; but is- 

 found here and is liable at any time to develop in numbers. The remedies suggested 

 consist chiefly of, careful cultivation of the soil so as to induce a vigorous growth,, 

 care at the time of thinning the rows and the use of obnoxious materials to deter 

 the females from egg-laying.
