fkuit-tree protector. 



Mr. D. Mendenhall, Fairfield, Iowa. — This is a rubber collar, 

 including a vessel for holding liquid, and so arranged that it will 

 be difficult for insects to crawl up a tree, and if they should cross 

 the collar they would be drowned. 



Dr. Isaac P. Trimble — This certainly is an improvement on the 

 metallic kind. But it cannot be wholly a protection. More know- 

 ledge is needed on the nature of insects. In Gramercy park the 

 city spent several hundred dollars in tree protectors, but it did no 

 good because the eggs of the insects which did the damage were 

 laid on the branches of the trees. As regards the great enemy of 

 fruit-trees in New England, the canker-worm, this device will be a 

 remedy only in part. Some have been so discouraged as to cut 

 down their trees. For the case is this: the female cannot fly; cer. 

 tainly, then, if she can be prevented from crawling up a tree, the 

 tree will be saved; but it has been discovered that the male wall 

 take her on his back in the night and fly with her into the tree. 



Mr. Simeon Baldwin, New Haven. — In our city the lead protectors 

 have been found useful; in putting them on, the tree is scraped 

 smooth, and the cup filled with oil. 



Mr. N. C. Meeker. — In Cleveland, Ohio, they have paid great 

 attention to ornamental fruit trees — perhaps more than in any 

 other city. They have most beautiful shaded avenues, and we have 

 a gentleman present who has been interested in these improvements, 

 both while a citizen and a member of Congress. The Club would 

 be glad to hear from him I refer to. 



Mr. J. W. Allen. — Formerly insects did some damage, but they 

 have disappeared, perhaps because we have so many trees. Our 

 climate is favorable for the growth of trees, also for all kinds of 

 fruit. We produce grapes largely, and excel Cincinnati in peach 

 culture. This we ascribe to the influence of the waters of Lake Erie. 



HUTCHINS' REVOLVING CHURN DASHER. 



Mr. A. B. Hutchins, Patchogue, L. I. — This is quite similar to the 

 screw of a propeller, and it was claimed superior to all others. It 

 was tried in a can of water. 



Mr. Solon Kobinson. — I have not the least doubt but it is equal to 

 the common dasher. 



Mr. N. C. Meeker. — We will never get butter by churmng that 

 water. If the dasher can be sent to some place where they have 

 cream, and tried, then we may know more about it.
