péndula from his nurseryman, what would he get ? Certainly not any kind of Robínia, but probably the Acàcia péndula of our Hortus Britannicus, an Australian shrub, which, so far from requiring the culture recommended by Mr. Rivers for his genus Acàcia, would, if planted out without protection, be probably killed by the first frost. If this be a means of lessening confusion, it is certainly rather difficult to discover in what manner it acts.

It now only remains for us to notice Mr. Rivers's intended attack on botanists for their “ incessant changes,” which he very inappropriately illustrates by Spach's division of the genus Ribes. Had Mr. Rivers been as thoroughly acquainted with the subject as he apparently wishes his readers to suppose him, he would have known that Spach's divisions have not been adopted even by “ Continental botanists."

We might say much more on this subject, but we think we have proved that Mr. Rivers's catalogue, so far from lessening, is likely to increase the confusion that at present prevails respecting the names of trees and shrubs. The evil, however, great as it is, cannot be of long duration ; for, from the rapidly increasing desire for the study of botany, and the equally rapidly increasing taste for arboriculture, the purchasers of trees and shrubs will soon know too much to be misled, in spite of all the efforts which those of the stationary school are making to retain them in ignorance.

We have not yet said anything respecting Mr. Rivers's “ Directions for Culture,” and we shall only notice the note to his genus Acàcia. He says the " trees are adapted to the background of shrub borders.” Now this is a point which we dispute, both with reference to taste and to culture. A background to shrubs ought to be composed of trees with dense opaque foliage, such as the oak and the beech, or of evergreens, such as the Lucombe oak, &c.; and not of trees with open light foliage that may be seen through, like that of the robinia. With respect to culture, the roots of trees suitable for the background of a shrubbery ought to be such as descend, like those of the oak or the chestnut, and not such as spread immediately under the surface of the ground, like those of the robinia or the elm ; which would soon ruin any border of shrubs, by depriving their roots of the greater portion of their nourishment. The errors in Mr. Rivers's notes are, however, scarcely worth noticing, when compared with those in his list of names.

But what we most deplore about Mr. Rivers's catalogue is, the baneful effect it must have on the minds of young gardeners wherever plants have been named according to it. The mere circumstance of a young man just beginning to acquire a knowledge of plants, being left to infer that it is of equal importance to distinguish between fourteen varieties of Robínia PseudAcàcia, as it is between all the species of the genus, is enough to fill the mind with despair, and either deter a young man from further pursuit, or leave him to conclude that it is in vain for him to acquire anything like botanical accuracy. The Babel-like confusion, however, which prevails in Mr. Rivers's catalogue, being now pointed out, both in this Magazine and in the Gardeners' Gazette, it will be the fault of young gardeners themselves if they are misled

Such an attempt as that of Mr. Rivers tends to show the great advantages that will result to gardeners and nurserymen from the establishment of public arboretums, with the plants correctly named, in different parts of the country; and it is a great satisfaction to us to know that the Derby Arboretum is in a central situation, and on what will shortly be the main road from London to Edinburgh and Glasgow, and from London to Liverpool and Dublin ; and hence, that it will probably be visited by gardeners and nurserymen from all parts of the island.

It may be useful to those purchasers of trees and shrubs who wish to have correct names with them, to be informed that the whole of the collection in the Derby Arboretum, amounting to about a thousand species and varieties, was furnished, with very few exceptions, by Messrs. Whitley and Osborn of the Fulham Nursery.

ART. III. On the_Conduct of the Horticultural Society towards

George Glenny, Esq., F.H.S. Communicated by Mr. GLENNY.

I last year put up with many slights from the Horticultural Society, and among them that of exclusion from prizes, on the ground that I had refused one of their medals ; nevertheless, I continued to send through the season some of the most important plants for exhibition.

On Tuesday last I sent four plants not very common, and on the contrary three of them were rather remarkable; but, notwithstanding everything else in the room was noticed by Dr. Lindley, my plants were not mentioned.

Now, I ask your readers whether such conduct is justifiable towards a Fellow of the Society, who has a right, as a partner, to his equal share of any profits and privilege the Society can boast ?

It is true, I have condemned many acts of the Council and the servants, but though you may do these things more gently than I have done, you have, as a public journalist, exercised the privilege of condemnation and approval as every other independent writer would; and it should be remembered that I never advanced a fact that I was not at the time ready to prove.

Art. IV. Notice of an Improvement made in the Mode of fixing

Mr. Booth's Wire Trellis for Espaliers. Communicated by W. B. Booth, F.H.S.

SINCE I forwarded the account you have published in Vol. XV. p. 630. of a wire trellis for espaliers, and the mode of erecting it, I have adopted another contrivance (fig. 1.) for fixing on the ends of the wires to draw them up, instead of the twisted

1

rope yarn formerly mentioned as having been used for that purpose. Perhaps it has little of novelty to recommend it to your notice; but any merit which it may possess belongs to Peter Copland, the blacksmith here, by whom it was constructed.

As it answers its purpose extremely well,
and may probably be useful to others, I
have great pleasure in supplying you
with the accompanying sketch (figs. 1.
and 3.) and description of it. It consists
of two flat pieces of iron (fig. 3. a a),
21 in. long, 14 in, wide, and half an inch
thick, having a couple of holes for the
screws (cc), and a groove (6 b) across
the middle of each, nearly deep enough
to receive the thickness of the wire. Two
round claws (d d), 4 in. long, with a joint
at (f) and a hole (c c) at the extremity
of each, which is flattened for the pur-
pose, are curved in such a manner that
one of the ends may be screwed on the
upper side, and the other on the lower
side, of the two flat pieces, and by means
of an eye and swivel, it can then be at-
tached to the hook (h) of the instrument
shown in fig. 15). in Vol. XV. p. 632.
The annexed sketch ( fig. 1.), representing
the whole when screwed on the wire, will,
however, convey a much better idea of
the thing than any description.

Carcler, Dec. 4. 1839.

[graphic]

Allow me to point out a mistake of your engraver in the sketch of the wire trellis in Vol. XV. p. 632. By fig. 153. it would appear as if the blocks of stone, into which the uprights and stays are fixed, rested on a foundation of masonwork : but this is not the case; the stones being so large and heavy, as to require nothing more than to be bedded in the places where they are intended to remain. To any practical person, such a foundation as is represented will appear quite unnecessary, but the fear of its misleading others has induced me to trouble you with this explanation.

Fig. 2. is the figure to which Mr. Booth refers, corrected agreeably to his directions. It may be useful to some of our readers to be informed that Mr. Booth’s espalier trellis can be put up in any part of the kingdom by workmen sent from the
