NATURAL HISTORY AND PHYSIOGRAPHY OF NtW BRUNSWICK. 33g 
Another detached part of the plateau is the elevated ridge, with 
three recognizable summits, just southeast of Mitchell Lake, and 
I would propose for this the name Sproule Mountains, for the 
first surveyor general of the province, one whose services deserve 
the grateful remembrance of our people. Another but smaller 
fragment is the conical mountain just east of the junction of 
Mitchell Lake outlet with the main stream, and for this I would 
suggest the name O'Connor Mountain, for Mr. Loggie’s prede- 
cessor in the Crown Land Office. Another detached part of the 
plateau occurs in a remarkable unnamed ridge to the eastward 
of Portage Brook, and there are yet others to the southward, of 
all degrees of prominence. 
The source of the Walkemik Branch is the little stream fall- 
ing from the plateau into Hough Lake, which is really an 
extension of Dunn Lake and separated from it only by flat bog. 
Dunn (or Logan) Lake is, of all the considerable lakes of the 
province, the most remote and difficult of access, the most un- 
spoiled (for it has never been lumbered even for pine), and 
almost the finest in its hill scenery.* being second in this respect 
only to Nictor, and perhaps Upsalquitch. It lies part way up 
the slope from basin to plateau (1576 feet above the sea), has 
rock-bound shores all around, except for some bog and marsh 
at its upper end and a sand beach at its easterly end. The huge 
granitic boulders of its shores support only a sparse spruce-heath 
forest. It is apparently deep, and empties from one side by a 
post-glacial outlet over a huge moraine. The surrounding 
splendidly forested hills are broken only in three places, to the 
northeast from Hough Lake where a valley exists, to the 
west, where the present outlet lies, and to the southeast where a 
low valley extends away, occupied in part by a small stream. In 
line with this is another brook (as Mr. Braithwaite has shown on 
his sketch map), emptying into Mitchell Lake, and beyond in the 
same line is Portage Brook, emptying into the North Pole Branch. 
I have no doubt that the pre-glacial outlet of Dunn Lake was 
* I believe this is the lake called by the Micmac Indians Wel-a-teg-e-ok, or 
“ Lake surrounded by hills,” a name applied by them to some lake on this 
branch, as I am in formed by Mr. Wm. Mclnnes, of the Geological Survey of 
Canada.
