300 THE CANADIAN NATURALIST. [Sept. 



would do well to use all precautions, those recommended here, or 

 any other, which will be beneficial in keeping them in check. 



There is no one particular remedy. The combined experience 

 of all interested is necessary for the removal of the evil, by 

 watching tlie habits, and thus learning more of the natural history 

 of these creatures. 



In conclusion, we would say that in a new country like this, 

 where immigration is going on among insects as well as among 

 men, it should be part of the duty of the Minister of Agriculture 

 to know what insect emigrants may be taking up their abode with 

 us to the injuries of our crops. And to this end it would be a 

 wise step to appoint competent Entomologists throughout the 

 Dominion (an appointment which has been so beneficial in the 

 neighboring States) to warn the Agriculturist of his many 

 enemies among insects and the best mode of getting rid of them. 



In the last number of the Naturalist appeared a paper, by Dr. 

 Sterry Hunt, on " The Probable Seat of Volcanic Action," 

 which was reprinted from the Geological Magazine for June, and 

 should have been credited to that journal, to which it was 

 originally communicated. This explanation is rendered the 

 more necessary from the fact that the paper in question is 

 reprinted in Scientific Opinion for October 20, and there 

 credited to the Canadian Naturalist as having been read before 

 the Natural History Society of Montreal, — a very natural though 

 incorrect inference, from the fact that the paper, by an oversight, 

 appeared in our pages as an original communication. 



MEETING OF THE BKITISH ASSOCIATION 

 AT EXETER. 



Want of space forbids our giving a detailed account of the 

 proceedings at this interesting meeting. We have thought it 

 advisable to give summaries only of some of the papers in the
