escape. We have since carried this somewhat farther, 

 having procured young plants of forest and orchard trees 

 and shrubs, and planted them in garden-pots, which are 

 plunged, as the gardeners term it, to defend them from 

 drought, and are ready for any experiment we choose to 

 make. These, besides, have the advantage of attracting 

 into the garden where the pots are plunged the insects 

 peculiar to the several trees ; and when we say that the

space occupied is only about thirty or forty feet in length, 

 by two in breadth, while none of the trees are suffered to 

 get above two or three feet high, we apprehend that few 

 persons, who have any garden at all, will find such a plan- 

 tation imsuitable to their convenience, if they are disposed 

 to such pursuits. Herbaceous plants can, for the most 

 part, be procured and planted at any season they may be 

 required, and hence it is not so necessary to keep any col- 

 lection of them growing ; whereas the transplanting of 

 trees in summer is most likely to kill them. (J. E.) 



This plan has, besides, the peculiar advantage of putting 

 it in our power, by means of sufficiently ample gauze cover- 

 ings, to make moths, butterflies, and other insects deposit 

 their eggs under our eye on the plants or trees on which 

 they would do so when at liberty, — an interesting part of 

 insect history, which, on account of the difficulties of re- 

 search, is as yet very imperfectly known. 



It would be in vain for us to attempt to enumerate the 

 various plants, trees, and other things on or in which the 

 larvae or perfect insects should be sought for, as such an 

 enumeration would necessarily be nearly as extensive as
