Even if Hayes's sight of the Open Polar Sea proved visionary, and certain unskilled observations failed of verification, yet his adventurous voyage was not barren of geographical results. He was the first civilized man to land on the shores of Ellesmere Land, along the coasts of which, between the seventy-seventh and seventy-eighth parallels, he made important discoveries; while farther to the northward, Hayes Sound, Bache Island, and other unknown lands and waters were added to our maps through his strenuous exertions. Breaking out his schooner on July 10, 1861, an unprecedentedly early date for an Arctic ship, he quickly decided that he could hope for no further northing in a sailing vessel. However, he crossed the strait to the unvisited shores of Ellesmere Land, where he made such an examination of the coast as was practicable, and then turned his face homeward. Hayes was fully alive to the absolute necessity of steam-power for complete Arctic success, but strictly limited means obliged him to go in a sailing vessel or not at all. He plainly foresaw the magnificent success awaiting the first expedition that should carry steam-power into Smith Sound, and full of dreams of future Arctic work he impatiently returned to the United States. It was not to be. Civil war raged, and the country called its loyal sons to arms. Hayes was not the man to falter at such a juncture. He at once tendered his schooner to the government for such use as was possible, and volunteered for the war, where his activity as the head of a great war hospital taxed to the utmost the mental and physical powers which had so long been occupied in arduous efforts to solve the riddle of the ice-free sea. Hayes visited Greenland a third time, in 1869, with the Arctic artist, William Bradford, in the steam-sealer Panther. Arctic scenery was their quest, and so they visited the fiord of Sermitsialik, where the inland ice, which covers the greater part of Greenland, pushes down into the sea as an enormous glacier, with a front two and a half miles wide. Here Hayes witnessed the birth of an iceberg, of which he says: "It would be impossible for mere words alone to convey an adequate idea of the action of this new-born child of the Arctic frosts. Think of a solid block of ice, a third of a mile deep, and more than half a mile in lateral diameter, hurled like a mere toy away into the water, and set to rolling to and fro by the impetus of the act. Picture this and you will have an image of power not to be seen by the action of any other forces upon the earth. The disturbance of the water was inconceivably fine. Waves of enormous magnitude were rolled up with great violence against the glacier, covering it with spray; and billows came tearing down the fiord, their progress marked by the crackling and crumbling ice which was everywhere in a state of the wildest agitation for the space of several miles."
