have expressed the belief that it extended southwest without a 
break as far as the North Branch of Miramichi. But I find that 
I was wrong as to this, for in fact, as I have since clearly seen, 
the great plateau ends just east of the Clearwater and Gulquac, 
whose branches, indeed, drain its western slope. The highlands 
then continue to the southwest in the form of a series of great 
rounded and more or less isolated ridges, whose every appear- 
ance and composition suggests an originally intrusive origin. 
These ridges, however, do not form, as would be expected, a 
single system, but they split partially into two ranges. The 
western range which runs southwest and continues with several 
marked gaps, to the St. John at Moose Mountain, is the striking 
and mountainous-looking range so prominently seen from parts 
of the Tobique Valley. The eastern range broadens out im- 
mensely to the southward and extends in a broad line, embracing 
all the country of the Burnt Hill, Clearwater and Rocky Brook, 
and extends beyond the Main Miramichi nearly to the Taxis. 
Between the two ranges lies an open trough or basin of an eleva- 
tion of 1400 feet, occupied largely by great flat bogs, with exten- 
sive deadwaters on the streams, or by gently undulating upland, 
from which isolated ridges or hills rise here or there. It is in 
this curious basin that the River de Chute, the Gulquac, the 
Burnt Hill and the Clearwater all take their rise, and all in com- 
mon escape in their respective directions between the isolated 
ridges of the highlands. Certainly the arrangement is remark- 
From its mouth up to the Forks it was surveyed in 1885, by hand compass and 
pacing, by Mr. Wm. Mclnnes, whose survey was used on the geological map, but 
above that point it is only sketched between the intersections of the timber lines, 
though I have added to my map much information obtained from other sources. 
The geological observations of Mr. Mclnnes are shown on the geological map, and 
mentioned in Professor Bailey’s Geological Report of 1885, G., 26, 27, while some 
observations of Mr. W. J. Wilson in 1899 are on the Surface Geology map and 
in Dr. Chalmers’ Report of 1902. Mr. Mclnnes in his survey was accompanied 
by Mr. J. W. Bailey, who has mentioned an incident of this trip in his Saint John 
River, 42. Some account of it near the Forks is given by Edward Jack in 
Acadiensis, V, 116, and there is an interesting narrative of a hunting trip upon 
it and the streams to the eastward by D. W. Green in Forest and Stream in June 
and July, 1902. But this comprises all the literature of the Clearwater so far as 
I know. The few miles of its lower course were once a great resort of salmon, 
and visited by many sportsmen.
