varieties, as the inarching frequently assists a sort that may be weaker by 
taking the surplus sap from the stronger-growing and equalising it and making 
both bear better. We find this 
to be the case to a great extent 
on the walls, particularly with 
old trees ; for example, five very 
old and fine-looking trees, that 
never bore any fruit, were in¬ 
arched all into one another seven 
years ago; the second year they 
had a crop, and have been bear¬ 
ing less or more ever since. 
Where Roses and Vines are 
used I would recommend iron 
for supports, as wood becomes 
troublesome and unsatisfactory— 
or, where the owner is partial to 
Plums, permanent iron supports 
would be useful; and I doubt if 
they would get sufficiently strong 
to bear the enormous crop that root-pruning and pinching insure under five 
or six years. Orchard-house treatment demonstrates most distinctly that 
nearly all our fruit trees become more productive under dwarfing treatment, 
such as these arches, &c., and they are exceedingly interesting and ornamental.

THE PINETUM. 
There are, perhaps, few sciences which have during the last thirty years 
advanced in an equal ratio with the art of gardening, and to this end none 
have contributed so much as the labours of my old and lamented friend John 
Claudius Loudon. He it was who produced the “ Arboretum et Fruticetum 
Britannicum,” and who first suggested the idea of forming arboreturns or col¬ 
lections of our hardy trees and shrubs scientifically arranged. Many of these 
collections have been formed, but we are sorry to say without adding to the 
picturesque appearance of the places where they have been made. We would 
point to Chiswick to illustrate this. Nothing can be more unhappy than the 
arboretum there as a specimen of landscape gardening, and so it must always 
be from the want of breadth of effect, which results from crowding so many 
objects into a limited space, these objects being all of dissimilar character. 
We cannot but think that a scientific arboretum is a nice and interesting 
thing to have; but we would treat it as an episode, and not introduce it as a 
general character in a fine place. 
The Pinetum originated after this time. When the first discoveries of the 
unhappy Douglas arrived in this country they produced a perfect mania; 
every one who had a garden had a Pine, and no situation was too absurd not to 
be adorned with one of the Douglas Firs. 
At this time the late Lady Grenville turned her attention to this tribe of 
plants, and she ever afterwards during a long life patronised and planted them 
largely, introducing all the new varieties as they have arrived. This is certainly 
one of the best situations for this collection in the kingdom, and has the best and 
finest specimens of the trees we are speaking of; there are masses of Scotch 
Pines which harmonise well with the others, and large tracts of common Furze 
and Heather; add to this the suitableness of the soil and the care and attention
