ARBORETUM. 
by Mr. Strutt respecting laying out this public 
garden were, that it was intended to be a place 
of recreation for the inhabitants of Derby and 
the neighbourhood, and for all other persons who 
chose to come.and see it; that it should be open 
two days in the week, and that one of these days 
should be Sunday, during proper hours; and that 
on other days a small sum should be required 
from persons entering the garden; or yearly ad- 
missions should be granted for certain moderate 
sums. That the gardens should be so laid out 
and arranged as not to be expensive to keep up; 
that a flower-garden and cottage, with the plan- 
tations already existing, should, if possible, be 
preserved; that a tool-house covered with ivy 
should also be preserved; that two lodges with 
gates, at the two extremities, should be built ; 
and that each lodge should have a room, to be 
considered as a public room, into which strangers 
might go and sit down, taking their own refresh- 
ments with them, without any charge being made 
by the occupant of the lodge, unless some as- 
sistance, such as hot water, plates, knives, and 
forks, &c., were required, in which case a small 
voluntary gratuity might be given. That there 
should be proper yards and conveniences at each 
lodge for the use of the public, apart from those 
to be exclusively used by the occupant of the 
lodge. That there should be open spaces in two 
or more parts of the garden, in which large tents 
might be pitched, a band of music placed, dancing 
carried on, &c, That certain vases and pedestals 
now in the flower-garden, and also certain others 
in Mr. Strutt’s garden in Derby, should be re- 
tained or introduced; and, finally, that some 
directions should be left for the management of 
the garden.” 
One of the nurseries at Camberwell! may be re- 
ferred to for illustration of what an arboretum is, 
what private enterprise can effect in forming 
one, and what benefits might result from planting 
one on even a limited scale on every large estate. 
It was founded in 1830, and noticed as follows, 
in July of next year, by Mr. Loudon :—“ We are 
most happy to state that Mr. Buchanan, junior, 
by extraordinary exertions during last autumn 
and winter, has collected together upwards of 
600 species and varieties of trees, and more than 
1,200 species and varieties of shrubs. These he 
is now arranging on both sides of a winding walk, 
on borders 8 feet broad, and which, when united, 
form a length cf 320 feet. The shrubs are placed 
in three rows in front, and ranged into three 
classes according to their heights: the trees form 
one row behind the shrubs. Both trees and 
shrubs are arranged alphabetically. The aver- 
age distance between the trecs is 3 feet ; but, not 
being crowded on either side, the extension of 
their branches will not be interrupted in two 
directions, though it will in the direction of the 
line. Though the shrubs are planted in three 
rows, yet each genus is kept by itself; the tallest 
from the walk, the shortest next the walk, and 
the intermediate sizes in the line between. When 
all the shrubby species of a genus are tall, they 
are placed in the third row; and when they are 
all short, in the first row; and the sizes are so 
distributed that the three rows are tolerably 
equally filled. For example, all the helianthe- 
mums are planted in the first row, and they, of 
course, extend so far along that row as to allow 
of several genera being introduced in the two 
rews behind them. Much room is thus saved 
(which, in a nursery so near London, is an impor- 
tant object), and the alphabetical order still pre- 
served. Hach tree and shrub will be named ac- 
cording to the nomenclature of our Hort. Brit., 
and on every tally, preceding the name, there 
will be a number. These numbers being all in 
regular series, should any tallies be taken out and 
transposed, they are easily replaced in correct 
order. As additions are made, the number of 
the species immediately preceding is put on the 
tally, with the addition of the letters of the 
alphabet in regular series, as exemplified in our 
supplement to the Hortus Britannicus.” 
It cannot be denied that much is lost, in a pic- 
turesque or ornamental view, by an attempt to 
arrange arboreous plants according to the affinity 
of their position in any system of scientific classi- 
fication. It seems but fair to state the disadvan- 
tages of arboretums, in this respect, as freely as 
we have adverted to their utility; and this we | 
cannot better do than in the words of Mr. Pax- 
ton in his ‘ Magazine of Botany.’ 
tony, and a slovenly displeasing irregularity ; two 
extremes equally to be deprecated in landscape | 
gardening. Paradoxical as this may appear, it is 
not the less correct. The uniformity alluded to 
is local, differing widely from comprehensive 
unity, it is confined to the different beds or plots 
set apart to the species of certain genera or tribes. 
These frequently assimilate so closely to each 
other in appearance, that in one place will be 
seen a bed of trees all evergreens; in juxtaposi- 
tion a cluster of dwarf shrubs, all flowering at 
the same time, and equally near; but in the op- 
posite direction a group of the largest kind of 
deciduous trees. All these are monotonous in 
themselves, while viewed in connection and com- 
parison with each other they present a total look 
of congruity. 
“ Nothing can be more adverse to genuine prin- 
ciples of landscape disposition than the system 
above described. Diversity of outline, of the 
form, colour, season, and duration of the foliage 
and flowers, is absolutely essential to the beauty 
of any scenery. Without this it appears sombre, 
formal, constrained, in one word, unnatural; and 
much as the imitation of nature has been despised 
by mere theorists, it is and must be the system 
pursued by all who would attain any eminence 
in this art. On the other hand, let it not be for- 
of the species being planted in the row farthest ; gotten that a garden is the medium which asso-
