" I am aware that I shall raise something of a storm in places where 



brick making is a business. But after so long studying upon the 

 evil, I do not speak at random, and further, I have something here 

 to corroborate my statements. [Dr. Underbill exhibited several 

 branches of forest and fruit trees which had been touched by these 

 gases, corresponding in appearance to his description.] After this 

 injury by the noxious gases, the plant louse and other insects are 

 more than usually active, and often complete the destruction of the 

 foliage. Where the gas falls upon the leaves of the hickory, it some- 

 times cuts a hole through the leaf. Pine is quickly destroyed by It, 

 the whole tree being effectually killed. In fact, this deleterious gas 

 injures almost every thing in the vegetable kingdom, and an efficient 

 and immediate remedy is most anxiously desired." 



The subject was, on motion, committed to Messrs. Ellsworth, Un- 

 derbill, Brink, Haight, and Darrach, who will report to the Farmers' 

 Club. 



The next business (diseases of potatoes) was taken up, and after 

 some brief remarks from Mr. Ellsworth, of Conn., it was laid on 

 the table for want of time to treat it at length. 



The culture of silk then came up, and on motion, Messrs. Van 

 Epps, Hyde, Summy and Byram, were appointed a committee to re- 

 port at the next meeting. 



Some conversation on silk, and in regard to the place for the next 

 meeting was held, and it was 



Resolved, That when we adjourn, w^e adjourn to meet at the Re- 

 pository of the American Institute in the Park, on Friday, at 10 

 o'clock, A. M. 



The 7th subject (culture of native grapes) then came up, and, 



On motion, it was referred to Messrs. Underbill, Meigs and Hall, 

 to report at the next meeting. 



The president then read a letter from S. B. Parsons, of Flushing, 

 L. I., recommending the establishment of a botanical garden in Flo- 

 rida, for the acclimation of tropical trees and plants, domesticating 

 of valuable exotics, &c. 



Gen. Dearborn gave a brief history of the experiment of a bota- 

 nic garden made by Dr. Perrine in Florida, during the Seminole
