and other trees of quicker growth at intermediate distances, as nurses Of 

 supernumeraries, the former are apt to be overgrown, and smothered by the 

 latter. To obviate this ill consequence, I have it in contemplation to try the 

 experiment of planting the oaks first, and leaving the other trees till the next, 

 or perhaps the second, or even the third season following, before they are 

 put in. For the first two or three years after transplanting, oaks can scarcely 

 be said to grow at all ; they commonly do little more than exist, or retain 

 life ; their growth or increase is a subsequent business, which does not com- 

 mence till the roots have taken good hold of the ground. Might not the 

 above plan, therefore, be attended with advantageous results ? Would it not 

 be the means of giving the oaks a start, as it were, so as to enable them to 

 compete with the other trees ? Perhaps Mr. Lawrence, or some other of 

 your correspondents, would give an opinion on the plan suggested. — W. T.

Lucombe's Evergreen Oak. (p. 185.) — In reply to your enquiry as to where 

 Lucombe's new evergreen oak can be purchased ; a supply, no doubt, can be 

 had at Messrs. Lucombe's and Pince's nursery, Exeter ; where, some time since, 

 I saw the original, a fine young tree of great beauty ; and, being struck with its 

 appearance, I ordered a couple of plants, to plant at Clawance, in Cornwall, 

 where they, with others of the same variety, more recently purchased, are doing 

 well. Mr. Pince informed me that the variety originated with them ; but 

 whether from acorns from abroad, or from those of the old Lucombe oak, 

 I do not now remember. — T. Ratger. Shortgrove, April 2. 1834.

Do Trees die away when their Roots come in Contact with the Roots of decayed 

 Oak Trees? — This is assei'ted in the Printing Machine, No. 5., on the autho- 

 rity of a Parisian Agricultural Report; and I should be glad if you, or any of

Forsyth' 's Plaster. — I wish that some correspondent, who may have had 

 experience in the use of this vegetable medicament, would state his opinion of 

 the degree of its usefulness, for the purpose for which it was recommended; 

 and give information of the extent to which it is still employed ; also whether 

 any other mixture has been adopted, which answers the purpose better. — T. 

 Rutger. Shortgrove, April, 1834.

The Appio Roots. — Sir Robert Kerr Porter, writing from Caraccas to Dr. 

 Hamilton of Plymouth, says, " I will put in the box a few of the Appio roots, 

 with directions how they are to be planted. That useful vegetable, I know, 

 has been already introduced into England, but I am not aware whether it has 

 been productive. Devonshire, I should think, will also prove better suited to 

 the growth of the Appio." Have you, or your readers, any acquaintance with 

 the nature or properties of the Appio ? and is it a Glycine ? I shall be glad 

 to learn something about it before I receive the roots. — Wm. Hamilton. Ply- 

 mouth, April 20. 1834.

Swelling of the Fruit of the Pine-apple, by extra Supplies of Water and Heat. 

 — E. K. of Ellesmere having requested farther information on this subject, 

 than what is given in p. 189., we applied to Mr. Munro, who informs us that 

 there is really very little to communicate. The two pine plants selected were 

 of the same size, in pots of the same size, and filled with the same soil. Each 

 plant showed fruit in an equal state of forwardness, at the time the experiment 

 was commenced. The one pot was plunged in the tan, in the usual manner, 

 and the other was placed in a shallow pan of water, and set on the tan close 

 to the plunged pot. The depth of the water was about 1| in., and it was kept
