103. — A Downward-forking Brook near Nictor Lake. 
Read April 3, 1906. 
Some time ago I was told by, Mr. Wm. H. Moore, of Scotch 
Lake, well known to the members of this Society as an observant 
student of animal life, that his brother, Adam Moore, the leading 
guide at Nictor Lake, had discoverd a brook which splits into two 
branches, one of which flows into the Mamozekel and the other 
into Nictor Lake. Since then he has sent me additional infor- 
mation about it, with a map ; and he tells me his brother has con- 
firmed his first discovery by a later visit and more careful 
inspection of the place, and that it has been seen by others and 
photographed. According to Mr. Moore’s map, the brook is the 
one shown on the Geological Survey map about four miles south 
of Nictor Lake, flowing west. One branch runs into South 
Branch of Mamozekel, as the Geological map shows, while the 
other branch runs northward into the pond at the source of the 
little Bald Mountain Brook flowing into Nictor Lake. The 
stream forks in an alder swamp, and it could easily be dammed 
by beavers or otherwise so as to send the entire stream down 
either one branch or the other. 
This is certainly a most unusual geographical feature. It 
requires that a stream descending from one watershed should 
happen to strike exactly upon the summit of another minor 
watershed. This entails a coincidence of conditions which must 
be extremely rare. Morphologically it is much like the occasional 
instance of a lake which, with an inlet, has two outlets into differ- 
ent systems ; but the forking stream requires a much more 
exactly balanced combination of factors.
