TRANSACTIONS OF THE SOCIETY. 57 



The disease, Mildew, on the gooseberry, peach, grape vine, &c. &c., is 

 checked, and entirely destroyed by a weak dressing of the solution. 



The Canker Worm. As the trees on this place are not troubled with this 

 worm, I have not had an opportunity of trying experiments by dressing 

 the trees, but have collected the worms, which the liquid kills by being 

 touched with it. The expense of labor and engines for dressing large 

 trees, to be effectual, may be more than the application of it will warrant ; 

 but I think, by saturating the ground under the trees with the liquid, about 

 the time the insects change from the chrysalis state and ascend the trees, 

 it will destroy them ; or when the moths are on the trees, before laying 

 their eggs, they may be destroyed without much labor. In either case, the 

 mixture may be applied much stronger than when it comes in contact with 

 the foliage. Laying it on the trunk and branches of the tree, of the con- 

 sistency of thick paint, destroys the brown scaly insect on the bark, and 

 gives the tree a smooth, glossy, and healthy appearance. 



I remain, Sir, your obedient servant,

Watertorvn, June 19, 1841. 



At this meeting the following business was also transacted. 



On motion of Mr. S. Walker, it was voted, that the Society offer a pre- 

 mium of one hundred dollars for a successful mode of destroying the cur- 

 culio, which has been so injurious to the plum tree. After this vote was 

 passed, Mr. Haggerston stated that he was requested to place at the dispo- 

 sal of the Society the sum of one hundred dollars, from the hands of 

 gentlemen interested in Horticulture, to be added to the amount of the pre- 

 mium offered by the Society, making the whole ttvo hundred dollars, and 

 it was voted that the whole subject should be under the charge of the 

 Fruit Committee. It was then voted that the premiums offered by the So- 

 ciety, with the exception of gratuities, and those offered in connection 

 with T. Lee, Esq., be confined to members of the Society. 



The Committee appointed to procure a new plate for a diploma, made a 

 verbal report that they had attended to that duty, and procured the en- 

 gravings, of which they submitted a copy for the inspection of the mem- 

 bers. The report was accepted, and the thanks of the Society were ten- 

 dered to the Committee for the acceptable manner in which they had dis- 

 charged their duty. They were requested to procure a sufficient number 

 of impressions for the use of the Society.
