Tobique. But the shadow of the deadly pulp-mill already looms over 

 it, and its glory will soon depart. 



This forest is extremely rich in game, especially moose and deer. 

 The lakes contain many trout and other fish, though in this respect 

 they are inferior to the Nepisiguit lakes. 



Physiography. The lake is 864 feet, more rather than less, above 

 mean sea level. Its maximum depth is 67 feet, surprisingly little for 

 a hill lake.* This depth diminishes to only 28 feet directly under 

 Sagamook, and lessens eastward so that Mud or Berton Lake, separa 

 ted from Nictor only by a morainic ridge and connected with it by a 

 short brook falling from one to two feet, is but a few feet deep, 

 though it is made thus shallow by deposits of organic mud similar to 

 that found in so many of our " mud lakes. "f The shores of Nictor 

 are usually bold and rocky, but in places the shores are of loose 

 morainic materials, and but rarely of gravel or sand. There are but 

 two islands, one of them narrow and low, apparently a moraine, and 

 the other of highly tilted slate rising abruptly from the bottom. The 

 latter bears a few trees and bushes, and forms the most charming 

 camping-ground that I know of in New Brunswick. Four large brooks 

 flow into the lakes, of which two, Bald Mountain and Caribou, flow 

 in broad deep valleys, which are doubtless the courses of ancient 

 rivers. Williams' Brook is new, and has upon it, not far from the 

 mouth, an irregular fall of some eight feet, whose murmur can be 

 heard from afar on still days, and the mist from which in certain 

 weathers hangs like smoke over the slope of Gordon. A striking 

 place is Spring Lake, practically an immense spring with a summer 

 temperature of but 41° or 42°. The lakes empty by the Little Tobique, 

 a very winding stream of much, though rather monotonous, beauty, 

 but perfectly ideal for the amateur canoeman. 



Origin of the Lake. I believe the lake occupies an ancient valley 

 of erosion choked by glacial drift. As I shall show in a later note, 

 the entire upper valley of the Nepisiguit is very ancient, and it could 

 not have emptied by its present course. It probably therefore ran 

 into Nictor Lake by way of the portage valley now followed by Caribou 

 Brook. The valley of the Little Tobique, though perhaps post-glacial
