The Sisters Brook * 
This comparatively short but otherwise important stream has 
its principal source in the attractive Sisters Lakes, which lie in 
a position shown by the map. The western lake, lying up against 
an abrupt ridge on the west, is especially pretty, while the east' 
ern is in flatter country which apparently extends a long way to 
the east and north. The stream runs with moderate flow at 
first, and receives branches as shown by the map ; but as it runs 
southward it enters a high country, and thence downward falls 
incessantly in a very deep V-shaped valley between parallel 
ridges of great height. Indeed the hills between it and the 
Clearwater apear to form an axial line of these highlands. 
Finally it falls by a very narrow gap into the valley of the main 
river, when it splits and enters the main stream by two nearly 
equal channels, one of which has recently been dammed for 
lumbering purposes. 
It seems probable that this stream is now only a portion of 
its former extent. The open basin extending east of the lakes, 
in conjunction with the peculiar positions of the Tahoe and Hurd 
Lakes, suggest a former outlet of this basin eastward into Dun- 
garvon. On the other hand, the extension of the basin north- 
ward from the lakes implies a former greater stream there, with 
possibly an old connection with the upper Clearwater. Also 
the marked alignment of the East Branch with the upper part 
of Rocky Brook implies a former connection there. But the 
* This stream is named Tabouimters on the Franquelin-DeMeulles map of 1686, 
obviously its Micmac name. It is called by the Maliseets Taboimnital (Jack, 
Journal of American Folk-Lore, VIII, 207), which, allowing for the usual substi- 
tution of r for l, is - practically the same word. Its general meaning is plain, 
for Taboo means two, of course in reference to its peculiar two outlets (one now 
closed artificially for lumbering purposes), which have given it the English name 
of Sisters. It appears first on the Allen map of 1831, but is curiously enough 
omitted from most later maps. It has not been surveyed, but is only sketched 
between timber line intersections. It was visited by W. J. Wilson in 1899, from 
whose observations it appears on the Surface Geology map. Although the lakes 
are a great hunting ground for moose, I have found only a single reference to it 
in sporting literature, viz., the article by Green mentioned in the preceding 
footnote.
