NATURAL HISTORY AND FHYSIOGRAPHY OF NEW BRUNSWICK. 441 
like those which prevail on the Gaspereau, above which, again, 
the banks are low all the way to the head of the stream, which 
is mostly shoal with considerable fall, and everywhere uncanoe- 
able. 
As the map will show, its head swings around pretty well 
into the line which must have been followed by the ancient 
predecessor of the Upper Gaspereau flowing across to the Kouchi- 
bouguacis. Its main course, however, lines up rather well 
with a possible Pleasant Brook — Trout Brook Valley, forming 
a branch of the Gaspereau-Kouchibouguacis valley; while its 
lowermost course lines up well with Six-Mile Brook, and 
perhaps occupies an identical syncline. 
Below Lake Stream the character of the river changes a 
little, and the country a great deal. The river becomes a suc- 
cession of long quickwaters and smooth glides, with only occas- 
sional deadwaters, separated by a good many rips and a few 
real rapids, with marked pitch but not at all rough, the river 
thus constituting one of the easiest and most pleasing of all 
canoe streams. Meantime the country becomes steadily higher, 
displaying marked terraces, rocky beaches, and bluffs, often 
in fine great circs and steep wooded slopes, with the country 
rolling up to a plateau behind. This higher country, apparently 
a plateau some 100 feet or more in elevation above the river, 
culminates near Coak Brook, and downwards falls off to the wide 
open marshy basin of the entering Gaspereau. The cliffs, in 
this part, while sometimes finely developed on the north bank, 
are upon the whole most abundant on the south bank, for the 
reason, I have no doubt, already given in connection with a 
similar phenomenon on the Gaspereau. 
In this part of its course the river has evidently cut across 
another section of higher country, the same, I take it, as north- 
westward is cut by the Gaspereau and Cains River, as described 
in my earlier notes thereon (Notes No. 118 and 125), while 
southeastward it forms the watershed between Coal Creek 
and Lake Stream. The greater drop of the river in this part, 
as compared with the parts above, is fully in harmony with the 
conditions prevailing on the corresponding parts of Cains River
