The Secretary alluded to the fact that Mr. Glover is now em- 

 ployed by Government at $2,000 a year, to investigate the sub- 

 ject of insects, and strongly commended the investigating tact 

 of Mr. Glover, " whose head and eyes were a traveling micro- 

 scope." 



PEACHES AND PLUMS. 



Mr. Bergen has lost his peaches and plums by curculio. 



Mr. Mapes had saved his fruit of various kinds this season, by 

 rapping the tree with a mallet frequently, to jar off the diseased 

 plums and curculios, which he then destroyed. His peaches, 

 plums, pears, &;c., are very prolific. 



Dr. Underbill had found that during this season the curculios 

 have been far less destructive than for ten years past, except on 

 high ground. He had planted one hundred and fifty trees lean- 

 ing over water, and not one of these had been injured by the 

 curculio. The parent will not deposit the egg where it will be 

 subject to destruction. Dr. Underbill exhibited several varieties 

 of these plums, in a perfect state, among which were the Jeffer- 

 son, a very large yellow plum; Lawrence's Favorite, and others. 

 In his experience, he prefers for cultivation the following varie- 

 ties, in the order named : 



1. Lawrence's Favorite. 6. Green Gage. 



2. The Jefferson. 7. Imperial Ottoman. 



3. Imperial Gage. 8. Golden Drop. 



4. Smith's Orleans. 9. La Empress. 



5. Washington. 



CATERPILLARS ON FRUIT TREES. 



Mr. Bergen had been greatly troubled with these pests, and he 

 and others wished to know how to get rid of them. Mr. Mapes 

 recommended using a long shaped lamp filled with a mixture of 

 camphene and alcohol, the latter in excess, and burning them on 

 the trees. Dr. Underbill had found nothing so good as destroy- 

 ing them with the hand. He had been obliged to cut down every 

 wild cherry tree on his place, and this, with the hand remedy, 

 had nearly freed him from the pest. Mr. Judd had precisely the 

 experience of Dr. Underbill. With the destruction of the wild 

 cherry trees, large and small, and a thorough destruction by the 

 hand in early summer, the caterpillars were nearly eradicated, 

 where before they had stripped the trees entirely bare of leaves. 

 The pinching operation should be performed early in the morn- 

 ing, while they were in their webs, and soon after their first ap-
