100 ABIES, OR SILVER FIRS 
in 1862. The differences between the two, and the 
verification of their differences, has been the text 
of many a debate in the fraternity of tree lovers. 
‘Professor Augustine Henry bids us take note of 
these, their differences. The young twigs of the 
Oregon are ‘ usually’ downy, while those of the 
Colorado are smooth. The foliage of the Oregon is 
pale green, in that of the Colorado the upper surface 
of the needles is bluish. 
The U.S.A, Department of Agriculture, in its Forest 
Service Contribution, goes one better. It bids us 
take note that while the Neptune’s trident-shaped 
bracts on the cones of the Oregon more or less point 
straight up the length of the cone, those upon ‘the 
Colorado variety are reflexed. If this is proved to 
be a universal practice on behalf of the two varieties, 
it is an ‘‘open sesame ” to the mysteries of their 
botanical disassociation. 
With the exception of this last remark, we have 
been only trying to review some English expressed 
views upon the subject of the two brother Douglases. 
We will now try to express a few American ideas 
on the subject of a tree that maybe is destined to 
play a great part in the history of the British timber 
industry.’ 
The first discovered of the two is generally known 
as the Oregon Douglas, though its domain ranges upon 
long Pacific slopes, from Vancouver Island to San 
Francisco, while the later-discovered one hails from 
farther east, among the ranges of the Rockies, and is 
generally referred to as the Colorado species. What 
America has to say upon the question of the wood 
value should be of interest to us. 
The Oregon Douglas represents the yellow narrow- 
ringed, and the Colorado the red and wide-ringed— 
although the slower grower of the two—wood of the 
lumberman ; and it is the yellow, narrow-ringed timber
