We consider first the lakes of the Main vSouth Branch. At 
the ^'ery source lies Louis Lake, one of the prettiest of all New 
Brunswick lakes, with clear, deej), spring-fed water, shores of 
rock and sand, and a border of low hardwood ridges.* Not 
only is this lake one of the most attractive in New Brunswick, 
but it is the most elevated of which any measurement has yet 
been made, lying as it does (a mean of two observations) at 1745 
feet above sea level. t It obviously lies close up to the summit 
of the plateau, for one has to go but a short way over a few feet 
of rise to the west to find Half Moon Lake, a shallow bog-bordered 
lake cut nearly in two by a stony bar, from which lake a stream 
fiows down a great slope into the Dungarvon; while a little 
to the north lie the Mud Lakes, amply described by their name, 
some fifty feet (by estimation) higher, which empty to the 
northward down an immense slope into North Branch Renous 
waters as shown by the map. The Louis Lake stream I have 
not seen down to Long Lake, but it is said to have no lakes, 
and must fall greatly, since Long Lake, a bent lake with stony 
shores, lies some 250 feet lower. The stream then falls greatly 
among immense boulders, deep down amongst which it is some- 
times completely out of sight. It receives the waters of Young 
Bull Lake — a pretty lake high up on the plateau — and passing 
through the shallow Mud Lake, and the pretty Grassy Lake, 
deep-set under Shunabit Mountain, enters Berton Lake. All 
of this stream has an aspect of newness which, in conjunction 
with its crookedness, makes it apparent that the valley is not 
an old one, but merely a recent overflow through chance channels 
from the top of the plateau. 
The lakes on the South Branch, — Berton, Nealis and Fowler, 
— are insignificant lakes, shallow and margined l)y bog or 
boulders, and made much larger than the original deadwaters 
*A very appreciative account of this lake, and its beauties, centering around an amusing 
hunting experience, is given by F. H. Risteen in Outing XXXVI, 1900, 36. 
fOetermined, with the other heights given on the map, by aneroid measurements made 
during our visit. Although the usual precautions, described in earlier Notes, were taken to 
ensure accuracy, the fact that in most cases we could make very few observations at 
each place renders' the figures less reliable than those given in many of the earlier Notes. '

XXIII, 32.5.
