No. 1.] GE0GN08TICAL OBSERVATIONS. 533 been spared. The coast presented the same appearance as far as Point Turnagain. The horizontal strata consisted of a kind of greyish-blue slaty clay, much impregnated with quartz, and passing into the new red sandstone. Cliffs of greenstone, porphyry slate, or red amygdaloid, were frequently imposed on the clay. At Slate Clay Point, on the eastern side of Walker's Bay, the layers of the indurated slate clay were disposed in a concentric manner, so as to form large globular concretions. The outer layers of the concretions running in- sensibly into each other. Having now enumerated, as distinctly as circumstances would permit, the rocks we had an opportunity of observing on the coast, we may state that the new red sandstone formation seems to prevail. All the islands visited were formed of trap or porphyry belonging to that formation, and judging from simi- larity of form, the rocks of the other islands belong to the same class. The gneiss formation is next in extent, and indeed it appears to run nearly parallel to the coast within the red sandstone from Cape Barrow across Hood's River above Wilberforce Falls to the bottom of Bathurst's Inlet, and from thence to Hope's Bay, on the western side of Melville Sound. The only foreign beds we observed in the gneiss were granite, perhaps quartz rock, and hom- blendic gneiss, or sienite. We saw no clay or mica slate, nor did we observe any formations intermediate between the gneiss, and new red sandstone; nor, except at Cape Barrow, where granite predominates, any other formation than the two just mentioned. Our opportunities for observation, however, were not extensive, the necessity of proceeding without delay limiting our geognostical and botanical excursions to the short period that was required to prepare breakfast or supper.
