The small-coned American Larch has a very wide area 
of distribution. The boundary-line extends unbroken from 
the extreme east of Newfoundland westwards over Canada 
and the northern U. S. A. to the Rockies, and north-west 
to the mouth of the Mackenzie River. From this point 
there is a gap in the line from the water-shed in the 
northern spur of the Rockies to the interior of Alaska, 
where it re-appears along the banks of the Yukon River, 
its tributaries, and lesser streams. The most northerly point 
is situated at the mouth of the Mackenzie, and a little 
to the east at the Anderson River; it nearly, buth never 
quite, reaches lat. 70° N. (see Map VIII). The most south- 
erly localities lie to the south of the Great Lakes, reaching 
lat. 40° N. south of Lake Michigan, and a trifle more 
southerly nearer east (about lat. 39° N.). Supworrn’s state-
