Below the Three Carrying Places the river widens and contains many islands, while the current is stiff. Two miles down it narrows to a chain and a half, presenting a heavy current but quite smooth. Again it widens and has 10 or 15 islands for three miles, when a constriction and heavy rapids occur. This fall is in two sections; the upper part can be run by keeping the west shore and running into the bay beyond. However a short portage is provided on the west side. The lower rapid is much heavier and is broken by an island. Nearly all the water follows the the eastern channel; in fact in low water all of it. In high water the bay to the west referred to above would not exist, and it might then be more difficult to cross to the Island portage, which is on the island and is about two chains long.

At both these rapids the rock is gneiss, but just where the portage crosses the island is a peculiar lens-shaped inclusion, ten feet wide at the north end, but pointing out on the south shore. It apparently dips 45° westwardly. The inclusion is in places quartzoze, in others highly altered, with much pyrite and magnetite. Under the microscope the rock shows augite as the prominent constituent, with a little quartz and plagioclase. The quantity of these is so trifling that the rock may be regarded as a pyroxenite. In the vicinity of this outcrop the gneiss itself is highly garnetiferous.

For the next 12 miles the river has a fair current and is bordered with clay and sand bluffs, the latter increasing in importance northward. These shore banks are, for the most part, clothed with young poplar. At the end of this 12 miles a considerable creek, Red Sucker known as Red Sucker, enters from Creek. the west. This stream was ascended two miles, in which distance three rapids were met. Beyond for two miles it is a con tinuous rapid over gneiss. The shores on both sides rise to the height of 100 feet and are composed of fine sand at the top and coarser materials below. Some pitch pine is found on the top of this ridge. A trip west from the foot of the long rapid, after passing the elevation, brings us to a long level spruce tract. Two small lakes were encountered, which, differing from the swampy lakes pre

viously seen, present shores of fine sand and shingle. From this fact and from the drier nature of the spruce flat it may be concluded that the whole of this region possesses sandy soil.

Lobstick

Three and a half miles below Red Sucker creek the river turns to the west with increased speed. One and a half Portage. miles lower it plunges down a declivity, necessitating the Lobstick portage of a half mile on the east side. An interesting series of rocks is shown here. On a small island above the rapids are seen tender mica schists striking northwest and southeast and dipping 20° N. This is followed by a dark, highly garnetiferous rock, which appears to be an altered augitesyenite. At the brink of the fall the rock is a distinct augite-syenite. On the east side, at the portage, we have a dark fine-grained rock of a schistose nature, followed by what appears to be a quartz porphyry. This is replaced by a typical augite-syenite with pyrite. Below the rapids is gneissoid mica schist, very rough and with pronounced jointing. The conclusions are, therefore, that a barrier of augite-syenite crosses the river east and west, inducing certain modifications in the gneiss and being itself rendered schistose at its borders.

Below the Lobstick portage the river must be crossed in dangerous water to the Burntwood portage on the opposite side, which passes by a trail of 300 yards a very bad piece of rapids. A mile of fair water succeeds and different routes seem to be followed beyond, some portaging on the east and some on the west side. A high clay hill gives the name of Clay falls to this rapid, and there is a portage along the face of the cliff on the east side of the river, and another but little used a short distance beyond. The river at this point is wide and filled with islands. The hill at the Clay falls referred to above shows in ascending order

20 feet fine sand interstratified with a coarser part and gravel.

One foot of stratified clay.

20 feet of stiff boulder clay with limestone erratics. 20 feet of fine stratified sand.

10 feet of stratified clay.

A half mile lower is a level easy portage known as the Birch portage, on the east side.
