gether with such other plants as from their importance in the arts, in- 

 dustries or medicine are of special interest. This Arboretum or Botanic 

 Garden occupies 60 acres in a commanding position, and contributes 

 not only a very pleasant park, but a place of great educational value to 

 the lover of trees and plants. 



Entomological Work. 

 As in the case of the Botanist, the Entomologist's chief work is 

 towards the protection of trees and fruits and crops generally against 

 the ravages of pests, but here we have to do with injurious insects that 

 attack and destroy, and which, if left unchecked, would soon make our 

 agriculture profitless. As already intimated, the work of the Entomol- 

 ogist includes the study of insects affecting live stock,such as the horn- 

 fiy, ticks, mites, etc. Apiculture and the production of honey also 

 comes within the scope of this study. 



The study of the life history of injurious and beneficial insects 

 carried on in laboratory, insectary, field and forest, is essential as a 

 first step towards the formulating of effective and practicable methods 

 for their control or destruction. It is a work, therefore, of primary 

 importance, and consequently one to which much close attention has 

 been given. 



More recently among the many methods of control is that of keep- 

 ing in check the development and spread of injurious insects by the 

 introduction and distribution of parasitic insects. These natural means 

 of control, as they may be called, bear much promise, and the Dominion 

 Entomologist has already met with some success in this comparatively 

 new sphere of work, and there is great hope that he may still be more 

 successful in stamping out, or at all events in preventing the spread of 

 certain insects otherwise uncontrollable. 



For the purpose of introducing, studying and establishing the 

 natural parasitic enemies of insect pests in localities in which the latter 

 are prevalent, a most important development of the entomological work 

 has been recently made in the equipment of field entomological labora- 

 tories in different parts of Canada. Six such entomological stations 

 were established during the past year, and even in the first year of their 

 history important results have been obtained. One of the most in- 

 teresting of these is the introduction, establishment and proven spread 

 in New Brunswick of an important European parasite of that dangerous 

 pest, the Brown Tail Moth. In Nova Scotia, Quebec, Ontario and British 

 Columbia valuable and encouraging results have already been obtained 

 in the laboratories established in these provinces.
