IN MUIR INLET, GLACIER BAY. high, has been added to the landscape. Only the end of this island was visible in 1879. New islands have been born in some of the other fiords also, and some still enveloped in the glaciers show only their heads as they bide their time to take their places in the young landscape. Here, then, we have the work of glacial earth-sculpture going on before our eyes, teaching lessons so plain that he who runs may read. Evidently all the glaciers hereabouts were no great time ago united, and with the multitude of glaciers which loaded the mountains to the south, once formed a grand continuous ice-sheet that flowed over all the island region of the coast and extended at least as far down as the Strait of Juan de Fuca. All the islands of the Alexander Archi- pelago, great and small, as well as the headlands and prom- ontories of the mainland, have a smooth, over-rubbed appearance, generally free from angles except where mod- ified by the after-action of local glaciers, and they all have the form of greatest strength with reference to their phys- ical structure and the action of an oversweeping ice sheet. The network of so called canals, passages, straits, chan-.
