THE. TREES OF BRITISH COLUMBIA. 
(For the WEST AMERICAN SCIENTIST.) 
The great island of Vancouver, the largest isle on the west 
coast of America, surrounded by many satellites of smaller 
order, especially in the Strait of Georgia, and the mainland of 
the province, compare favorably in respect of forests, to any 
State, province or country, either in North America or in Europe. 
This great and magnificent province of British Columbia, now 
brought into communication with eastern parts of the Dominion 
through the Canadian Pacific Railway, contains such a variety 
of plants from the magnificent Douglas fir to the modest cow- 
slips that the future botanist of British Columbia, will find here 
a most luxuriant field for study. 
The short account of some of the trees and other plants given 
here is written with the purpose that the numerous readers of the 
West AMERICAN SCIENTIST may form an idea of the magnitude 
of botanical life in this remote province. The writer of these 
lines has been but a short timein British Columbia, consequently 
the account of plants will be found to be very incomplete; still 
the author will endeavor to present as many facts as possible, 
either from his own observations, or from those gathered by the 
Government Department of Agriculture. 
In the province of British Columbia the Coniferz are to be 
found in great profusion. Among them the first place belongs 
to the Douglas Spruce, sometimes called Douglas fir, Douglas 
pine, and Oregon pine (Pseudotsuga Douglasi1), a magnificent 
tree, often over 250 feet high and 30 feet in circumference, and 
whose bark is sometimes 9 or 10 inches in thickness. This tree 
grows very rapidly, and is divided by the woodman into two 
kinds, yellow and red. The first has a reddish-yellow, knotty
