NATURAL HISTORY AND PHYSIOGRAPHY OF NEW BRUNSWICK. 207 
I could not be sure. The river meantime becomes very quiet, 
and runs between its high walls and occasional cliffs in a series 
of great stillwaters and gently moving quickwaters, with only 
occasional little rips between. This part of the river is not post 
glacial, for there is much intervale and glacial material, but it 
has an appearance in places almost of “interglacial” origin. 
At Layton and Blue Rock Brooks the country falls off and is 
lower and more open, but soon rises again, while the river for 
a distance becomes shoaler and swifter. Below Ten Mile Brook 
the valley becomes narrower and the valley walls steeper and 
higher with many fine cliffs, this part appearing almost “inter- 
glacial” in age, and cut 100 feet or more into the plateau, while 
the river is narrower and deeper. But soon it again opens out, 
and develops some fine slopes and low terraces, which have been 
cleared and farmed, though now once more reverting to wilder- 
ness. Thus the river continues down to Arbo’s, now the upper- 
most house (though abandoned) on the river, and thus it 
continues also, a series of fine long Stillwater reaches through 
high valley walls, but with occasional fine low terraces, a very 
pleasing country, down to Six Mile Brook, where now stands 
the uppermost occupied house on the river. 
Below Six Mile Brook the valley is wider, though it rises on 
one side or the other into a high wall, sometimes in abrupt cliffs, 
but there is room for wide terraces and intervales.* These are 
more or less cleared and settled, but in many places are abandoned 
and growing up in park-like and attractive manner, providing 
innumerable pleasing camp-grounds. Meanwhile the river bed 
remains mostly quiet and deep, forming a canoe stream of the 
easiest and quietest character, explaining very fully why this 
route to the St. John was such a favorite in early days. The 
low terraces afford at many places, and especially at Muzrolls 
Brt>ok, and Sabbies River, camp grounds of the most pleasing 
character, which I have no doubt were great favorites in Indian 
and French times. Below Salmon Brook the river turns abruptly 
*At one place, at the Oxbow, are some mineral springs which we examined. They come 
out of a high rock bank, and stain the rocks a rusty red, but have no very marked taste,
