[Footnote 13: I am indebted to Dr. William Stimpson for a careful examination and comparison of this collection, the results of which were published by him in the "Proceedings" of the Academy of Natural Sciences of Philadelphia, for May, 1863. The collection contains little that is wholly new; but, as Dr. Stimpson has remarked, "They possess great interest from having been found, in great part, in localities much nearer the Pole than any previous expeditions have succeeded in reaching on the American side of the Arctic Circle. They include some species hitherto found only on the European side; and, we may add, the number of species collected by Dr. Hayes is greater than that brought back by any single expedition which has yet visited those seas, as far as can be judged by published accounts." The collection embraces, of _Crustacea_, 22 species; _Annelida_, 18 species; _Mollusca_, 21 species; _Echinodermata_, 7 species; _Acalephæ_, 1 specie; and, besides these, a considerable number of _Nudibranchiata_, _Actiniæ_, etc., which cannot well be determined from alcoholic specimens.] [Sidenote: AN ENLIVENING SCENE.] We arrived at the lake in the midst of a very enlivening scene. The snow had mainly disappeared from the valley, and, although no flowers had yet appeared, the early vegetation was covering the banks with green, and the feeble growths opened their little leaves almost under the very snow, and stood alive and fresh in the frozen turf, looking as glad of the spring as their more ambitious cousins of the warm south. Numerous small herds of reindeer had come down from the mountains to fatten on this newly budding life. Gushing rivulets and fantastic waterfalls mingled their pleasant music with the ceaseless hum of birds, myriads of which sat upon the rocks of the hill-side, or were perched upon the cliffs, or sailed through the air in swarms so thick that they seemed like a dark cloud passing before the sun. These birds were the hitherto mentioned little auk (_uria allæ_), and are a water-fowl not larger than a quail. The swift flutter of their wings and their constant cry filled the air with a roar like that of a storm advancing among the forest trees. The valley was glowing with the sunlight of the early morning, which streamed in over the glacier, and robed hill, mountain, and plain in brightness. Hans had pitched his tent at the further end of the lake, and Kalutunah came up with Myouk and Alatak, and joined him. Jensen quickly shot a deer, and Hans brought us some auks; and, before going to work, we drew around a large rock, of which we made a table, and partook of a substantial dinner of Carl's preparation, washing it down with purest water from the glacier, while listening to the music of gurgling streams and the song of birds.
