Correspondence. — The correspondence of the Division has shown a considerable 

 increase over that of previous years, and the number of subjects inquired about has 

 shown that the Division is becoming well known as a source of information with 

 regard to all matters relating to the scientific consideration of insects and plants in 

 connection with agriculture and horticulture. The number of letters exclusive of 

 circulars entered in the Division register, as received from April 1, 1907, to April 1, 

 1908, was 4,030, and the number despatched 3,640. Articles relating to outbreaks 

 of insects, the treatment of well-known pests and the best methods of dealing with 

 noxious weeds have been prepared for local newspapers and for agricultural journals, 

 whenever required. Many of these have been at the request of correspondents who 

 have intimated that they were of general interest. 



Meetings. — Meetings of farmers' institutes and other agricultural associations, 

 teachers' associations, &c., have been attended by the Entomologist and Botanist when- 

 ever other official duties would permit. 



June 7, 1907: Annapolis Royal, N.S. — A convention of fruit growers to consider 

 the best measures to adopt to control the Brown-tail moth. An address was given on 

 the habits of this insect and its history in America. A full and interesting discussion 

 was carried on, and much information elicited with regard to the localities where it 

 had occurred in Nova Scotia, and the vigorous steps which were being takc'i by the 

 Provincial Secretary for Agriculture for Nova Scotia. 



June 23 and 24: Boston, Mass. — By invitation of the legislative committee of 

 the Commonwealth of Massachusetts, through Mr. A. H. Kirkland, Superintendent 

 for suppressing the Gypsy and Brov/n-tail moths and with the approval of His 

 Excellency Governor Curtis Guild, Jr., I was invited to be one of fourteen entomolo- 

 gists, from all parts of the world, to inspect and report upon the extensive work which 

 had been done in the New England States in fighting against the Gypsy and Brown- 

 tail moths, and particularly with regard to the importation of parasites of these insects 

 from Europe. On June 24 I visited the laboratories at Saugus, Mass., with Superin- 

 tendent A. 11. Kirkland, and the following day, in company with Prof. John B. Smith, 

 State Entomologist for New Jersey, Dr. E. P. Eelt, State Entomologist for Nev.- York, 

 Mr. Kirkland and Mr. E. H. Mosher, we covered a great deal of ground in an 

 automobile and examined the work which had been done in clearing street trees, parks 

 and woodlands from these aggressive enemies. The success of this whole movement, 

 both in fighting against-these caterpillars by the ordinary means and by the extensive 

 importation of parasites, has been so remarkable that I was much pleased to have 

 this opportunity of examining into the details of the work in the company of the 

 experienced entomologists above named. The whole work forms without doubt the 

 most remarkable experiment which has ever been tried in econoinic entomology. That 

 in only two seasons 8,000 miles of streets should have been practically freed of devastat- 

 ing caterpillars of two of the worst known pests of shade trees, is a triumph of applied
