Early this evening we entered between bold cliffs into Square Island Harbor, latitude about 53 deg.. It is a deep and deeply sheltered dog's hole,--dogs and dirt could make it such,--but overhung by purple hills, which proved, on subsequent inspection, to be largely composed of an impure labradorite. Labradorite, the reader may know, is a crystallized feldspar, with traces of other minerals. In its pure state it is opalescent, exhibiting vivid gleams of blue, green, gold, and copper-color, and, more rarely, of rose,--and is then, and deservedly, reckoned a precious stone. The general character of the rock here is sienitic; but, besides this peculiar quality of feldspar, the hornblende appears as actinolite, (ray-stone,) so called from the form of its crystallization; while the quartz element is faintly present, or appears in separate masses. The purple of the hills is due not only to the labradorite, which has that as a stable color, but also to a purple lichen, which clothes much of the rock on this coast. I found also fine masses of mica imbedded in quartz, edge upwards, and so compact that its lamination was not perceptible. Indeed, I did not, with my novice eyes, immediately recognize it, for it appeared a handsome copper-colored rock, projecting slightly from the quartz, as if more enduring. Next day there was trouting, with a little, and but a little, better than the usual minnow result. And on the next, the floe-ice poured in and packed the harbor like a box of sardines. The scene became utterly Arctic,--rock above, and ice below. Rock, ice, and three imprisoned ships; which last, in their helpless isolation, gave less the sense of companionship than of a triple solitude. And when next day, Sunday, the third day of July, I walked ashore on the ice with a hundred feet of water beneath, summer seemed a worn-out tradition, and one felt that the frozen North had gone out over the world as to a lawful inheritance.
