In this last list the presence of three evergreen trees, making 

 up perhaps one-tenth of the forest, seems to indicate poorer soil 

 than that west of Brownsville. 



It is also significant that more trees and shrubs and fewer 

 weeds, in proportion to the distance traveled, were seen in this 

 section than in the others, even though some of the weeds west 

 of Brownsville were concealed by snow. 



A few notes on the local distribution of some of the species 

 may now be added. Fagus and Acer SaccJmrum were not seen at 

 all in the lake plains, except once each in Welland County; but 

 they appeared pretty promptly on entering the rolling country 

 near Ridgetown. Rhus typhina was first seen a little farther 

 along, near the boundary between Kent and Elgin Counties. 

 Castanea dentata, which is not common in Canada, was seen two 

 or three times in Elgin County. Pinus Strobus, which was not 

 observed in the western half of the route at all, appeared rather 

 suddenly after passing Brownsville, and was fairly common be- 

 tween there and Welland. (In that section there are many fences 

 made of its stumps, as in parts of Michigan where it was once 

 abundant.) Thuya was seen several times between La Salette 

 and Townsend Centre, Tsuga twice near Windham, and Larix 

 once near Waterford, making four conifers seen in the pine area
