The more elevated regions are totally destitute of vegetation, except the tripe des roches, which gives to the hills a somber color, anything but inspiring. Fully three-fourths of the more elevated region is, with the exception of black lichens, barren rock. Everywhere is the evidence of long continued glacial action. The southern exposures of all the hills show the same character of wearing, and, in many instances, a fine polish on the rocks forming their bases. This smoothness extends nearly to the summits of the higher peaks. These again are somewhat rougher and often broken into jagged, angular fragments, frequently of immense size. The more moderate elevations are usually rounded summits on whose higher portions may be found huge bowlders of rock having a different character from that upon which they rest, proving that they were carried there by masses of ice in the glacial ages. The northern extremity of all the ridges and spurs indicate that the glacial sheet moved to the north-northwest, for these portions of the rocks are so jagged and sharp edged as to appear to have been broken but yesterday. The rivers of this district are numerous and several are of great size, although but two of them are navigable for more than 100 miles, and this only for boats of light draft. The river usually known as George’s river (Kan´gûk¢lua´luksoak) is the largest on the eastern side. This stream takes its rise about latitude 55° and pursues a moderately tortuous course nearly northward and falls into the eastern side of Ungava Bay. It has a wide bay-like mouth narrowing rapidly at the mouth proper. Swift rapids are formed here on account of an island near the center. Beyond this the river expands and has an average width of half a mile for a distance of about 18 miles where the river bends eastward and forms rapids for over 2 miles. It is navigable for the steamer _Labrador_ only about 12 miles. Beyond the rapids it runs tolerably smooth and deep for nearly 40 miles and thence to the source is a series of rapids and falls, rendering portages frequent, and making it utterly impracticable for even a heavy skiff to ascend beyond 70 miles from the mouth. Indians assert that high falls occur about 150 miles from the mouth of the George’s river. The water is said to fall from a terrific height, almost perpendicularly, and it causes the ground to tremble so that the thundering noise may be heard for more than a day’s journey from it. The tide at the mouth of George’s river rises 53 feet, and at the Anchorage, opposite the newly established station of Fort George, some 12 miles from its mouth, 42 feet.
