Trees on McGill University Grounds. 409 



but on application to Mr. Shepheard, he kindly consented 

 to lay out the portion of the ground on the east side of 

 the avenue, in a manner suitable to the changed condi- 

 tions. 



Early in our planting opei-ations, the Graduates' Society, 

 at that time recently organized by Mr. Brown Chamberlin 

 and others, took an interest in the matter, and proposed to 

 plant a "Graduates' Walk," extending from the great elm 

 round by the bank of the brook to Sherbrooke Street. They 

 prosecuted the work actively and in a few years had the 

 walk stocked with trees, the latest of which was an elm 

 planted in honour of the visit of H. R. H. the Prince of 

 Wales in 1860. The Graduates' Walk is now for the most 

 part merged in the approach to the new W. 0. McDonald 

 Physics Building, and most of its trees have disappeared 

 except those at its extremities. 



Notes have been kept since 1855, of the results of the 

 planting and attempts to introduce foreign trees and shrubs, 

 and it was hoped that these experiments and observations 

 would have been continued by Prof. Penhallow, but since 

 the park and its trees may now be considered as things of 

 the past, and any experiments hereafter made will be car- 

 ried on under new conditions in the ground leased from the 

 Trafalgar Institute, or elsewhere, it may be well to record 

 for the benefit of others the results of the observations 

 made. 



It may be premised here that the grounds are sheltered 

 by the mountain, have a favourable exposure to the south- 

 east, and have three varieties of soil — the sandy soil afforded 

 by the Pleistocene Saxicava-sand toward the front, claj^soil 

 resting on Leda-clay and Boulder-clay and the alluvial soil 

 in the little ravine, not to mention the rocky ground on 

 Trenton limestone and old quarry p'ts, which was, for the 

 most part, occupied by the Medical Faculty's building. 



In noticing the trees and shrubs, I shall take them in 

 no very definite order, but shall give a list with notes on 

 each species, taking native trees and shrubs first.
