As in the animal kingdom man holds the first rank in regard to external circumstances, so do trees and shrubs hold precisely the same rank in the kingdom of vegetable nature. In their structure they are alike superior, in their form more symmetrical, and in their duration far less evanescent. To their nourishment, also, their more volatile allies contribute by their death, since they feed and nourish upon (as it were) the gases generated from their remains.
It need not, and does not, then, surprise us, that their skilful and judicious cultivation has come to be regarded as the noblest occupation of the horticulturist; or that a fine specimen of a rare exotic species should be looked upon with the proudest and most pleasurable emotions. In the human mind there is a natural impressibility with the grand and beautiful; and, as has been truly said - " Than a tree, a grander child earth bears not".
But the appearance of these monarchs of vegetation is most powerfully affected by locality and difference of treatment; and our present object is to institute a comparison between the method of growing them in what are termed arboretumsy and that of planting them singly or in groups, without any regard to botanical order or affinity, in conspicuous parts of the pleasure grounds of suburban and country residences. There is undoubtedly merit attached to each of these systems; therefore it is proper we should examine the claims of each, and endeavor to show which is the most ornamental and appropriate.
