é chemical composicion of the soil. Hence an intimate re- ; lation exists between the botany of any district of coun- { try and its geology and topography; and, therefore, inde-

pendently of the climate, certain plants, whether placed r by nature or art, will flourish, or decay, according as the temperature and composition of the soil, is favorable or unfavorable to their growth. A botanical survey of the park has been made, for the purpose of ascertaining the . a. nature of the existing vegetation, to learn how far it = - could be made available in the projected improvements, as well as to know its character, as an indication of what _ peculiar class of plants would prove most flourishing if - transplanted to this ground, as also to discover what alter- ations the soil would require in order to admit of an in- . creased variety. .

This forms the basis of a botanical index which can always be made complete by a careful register of the plants and trees introduced. The investigation has not extended through all the seasons, which, in their turn, de-

velop their peculiar plants; and is, therefore, in some respects, incomplete; still, so far as the useful trees and shrubs are concerned, it is believed that none have been overlooked.

Although this investigation has added nothing new to botanical science, yet it is necessary that the existing trees and plants should be described so as to be identified, and their importance properly estimated. <A familiar de- scription has been preferred to strictly botanical language, to convey all that is necessary with regard to the present vegetation. The catalogue will be added to during the ensuing season.

For present purposes, the plants are arranged simply in alphabetical order, without reference to any particular classification.
