to its mouth. It rises in Snowshoe Lake, said to be a typical 
small marsh drordered lake in a flat country, at a heights 
judging from the railway levels, of about 340 feet above the 
sea, — an elevation a hundred feet greater than that of the 
source of the main river. At the crossing of the railroad it is 
a small brown stream which winds sluggishly towards 
the westward through alders, and then takes a more open 
and rapid, and finally very winding course to the Forks, 
which it reaches in the midst of extensive open natural 
meadows. Here it receives the West Branch, a smaller 
stream, which, however, occupies a wide valley crossed by 
a great fill of the new railway, and heads, I am told, in an 
extensive bog as shown by our map. The stream then flows 
westward for some two miles, passing from the meadows into 
a country of rounded, burnt, barren, glacial hills, through 
which it runs smoothly in long uniform still-waters broken 
by short abrupt rips, this part forming a charming canoe 
stream. Then it swings to the southward and enters a higher 
and now wooded country, still of glacial material, for no ledge 
rock shows; it now becomes wider and shoaler and acquire 
much drop, until presently it is falling in continuous rapid 
down a very stony and bouldery bed of glacial materials, 
making a stream of much attractiveness though considerable 
difficulty for the canoeman. Thus it continues for some five 
or six miles, receiving several branches, of which some are very 
pretty; then it crosses some sandstone ledges of a reddish 
color and gradually enters an open attractive intervale basin 
in which it receives a large brook from the westward. In 
this basin it winds for some two miles, and then it enters again 
a higher country in which, enlarged in size, it continues for 
two or three miles, still wide, rapid and shallow, but with less 
drop than above. In this part, on the right bank, comes in a 
falling cold spring brook with a charming camp ground on 
a high grassy brow just below. All this part, like the stream 
as a whole, is surprisingly large, attractive, and rapid, having 
thus more the aspect of some of the northern rivers than of 
those distinctive of the Central Plain — in this respect recalling
