PROCEEDINGS OF THE SUMMER MEETING. 18 



Toastmaster Morrill, by a number of gentlemen, concluding with Mr. R. 

 M. Kellogg, who offered the following resolutions, which were adopted 

 with hearty unanimity: 



Having for two days passed an almost charmed existence within the groves of 

 the grandly beautiful campus of Michigan Agricultural College, and having received 

 all possible attention and courtesy from the college board and faculty, it is by the 

 members of the Michigan Horticultural Society, 



Resolved, That we find ourselves a thousand fold repaid for our pains and expense 

 in coming here, by the knowledge we have gained of the methods and results of 

 work in the several departments of the college, the valuable papers and addresses 

 to which we have listened, and the scenes of beauty we have beheld in the gardens, 

 lawns, groves, fields, and forest. We find this college to be an institution admirably 

 managed in all its details, worthy of the continued liberal and appreciative care of 

 this State; and we urge every fruitgrower and every farmer to pay it a thorough 

 visit that he may see and know for himself, for scarcely could he find elsewhere 

 in the United States so much of value, interest, and pleasure. 



Resolved, That we thus express and tender to the College board and faculty, for 

 their manifold kindnesses, our most sincere thanks. 



PAPEES AND DISCUSSIONS. 



INJURIOUS INSECTS PECULIAR TO THIS SEASON. 



BY PROF. G. C. DAVIS, MICHIGAN AGRICULTURAL COLLEGE. 



As each spring opens with its melting snow and bright sunshine, I can 

 but wonder what new insects will appear this season; what will be the 

 first new pest to need my attention; what and how many injurious species 

 will be abundant this year, and what ones will not be common. Each 

 season is sure to bring some insect to our notice by producing some injury 

 where it was never known to do harm before. Certain species, such as 

 the codlin moth, seem to have come to stay, and vary but little in num- 

 bers each season; other species that are well known as injurious, may be 

 scarce, from various causes, for years, and then suddenly reappear in 

 great numbers, continue to be very common for one or more years, and 

 again disappear. The apple tree canker-worm is a good illustration of 

 this. Two years ago it began to make its presence known by placing on 

 exhibition a few leafless orchards. Last year scarcely an orchard 

 escaped its attack. This spring it was common, though not so common 

 as last year; and, too, people were prepared to treat it this spring, and few 

 orchards were stripped of their foliage. Next year it is doubtful whether 

 the canker worm will do any injury except it be in a few isolated cases. 

 Insects and their attacks vary quite as much as the different kinds of fruit 

 or vegetables vary. Some years certain species are abundant, and other 

 vears thev are too scarce to cause anv noticeable injury.
