THE GEOGEAPHICAL DISTRIBUTION OF FOREST TREES 



IN CANADA. 



By DR. ROBERT BELL. 



(Read before the Society at Edinburgh and Glasgow, in March.) 



(With a Map.) 

 INTRODUCTION. 



THE writer has studied the geographical distribution of the forest trees 

 of Canada for the last forty years, and during all that time he has had 

 exceptional opportunities for observation, having been engaged each year 

 in exploring, in connection with the Government Geological Survey, one 

 part or another of the region represented on the accompanying map ; and, 

 in addition to this extensive personal observation, he has collected much 

 information on the subject from a great number of other travellers. 

 The result has been to ascertain, with considerable accuracy, the limits of 

 distribution of all our native trees from the Atlantic Ocean as far west 

 as the prairie regions. 



TREE-LINE MAP. 



In 1873 he prepared a large map showing the northern limits 

 of the principal trees in the four original provinces of the Dominion, 

 and a reduction of this sheet was published in the report of the 

 Montreal Horticultural Society and Fruit Growers' Association for 1879. 

 The timber-tree map accompanying his official report for 1880, published 

 by the Geological Survey in 1882, gives the general northern limits 

 of thirty of our principal forest trees east of the Rocky mountains. 

 The thirty species whose boundaries are shown with greater accuracy on 

 the map accompanying the present paper embrace most of the same 

 trees ; but a few substitutions have been made in order to introduce other 

 species of more general interest without increasing the total number
