several species of the nettle tree (Celtis occidentalism L.) will 

 be observed. Prom this point to the band stand and as far 

 beyond as the entrance to the fort, numerous specimens will 

 be found. The only other locality near Montreal, where 

 this species occurs, is at St. Anne's. On the road from the 

 station to Dr. Gird wood's, and about half way to the latter 

 place, a number of line trees may be seen on each side of 

 the highway. Again, about two miles beyond, near Mr. 

 Forget's, there are several more trees. 



The three thorned acacia (Gleditschia triacanthos, L.), is 

 found within the fort, near the old officers' quarters. The 

 trees are fine specimens and stand in a row where planted 

 for ornamental purposes. While this species is commonly 

 cultivated in Southern Ontario, it is but rarely found in 

 Quebec, the only other locality known to me being Cote St. 

 Antoine. 



The other trees found are chiefly those common to the 

 vicinity of Montreal. They embrace the common beech 

 (Fagus ferruginea, Ait.), white oak (Quercus alba, L.), an occa- 

 sional specimen of the white hickory (Corya alba, JSutt.), one 

 specimen of black walnut (Juglans nigra, L.) This tree is 

 never found in Quebec in the wild state, and but few instan- 

 ces of its occurrence in Cultivation here are known to me. 

 At the Botanic Garden, at the top of Cote des Neiges hill, 

 are one large tree and two small ones, all apparently thrifty. 



White birch (Betula populifolia, Ait.), sugar maple {Acer 

 saccharinum, Wang.), and silver maple {Acer dasycarpum, 

 Bhrh.), the latter planted along the road for shade purposes, 

 are abundant, as also are the American basswood {Tilia 

 americana, L.), white elm (JJlmus americana, L.), and but- 

 ternut (Juglans cinerea, L.) Slippery or red elm (Ulmus 

 fulva, Michx.), and English elm (Ulmus campestris) ,■ are met 

 with occasionally. 



Of the smaller trees and shrubs, the hawthorns, so abun- 

 dant everywhere about Montreal, are represented by Cra- 

 taegus coccinea and Crataegus tomentosa. The round leaved 

 cornel (Cornus circinata, L'Her.), common elder (Sambucus 

 racemosa, L.), choke cherry (Prunus Virginiana, L.), sumac
