Lieutenant John W. Danenhower, U. S. N., was appointed navigator; Dr. J. M. Ambler, surgeon; Jerome J. Collins, meteorologist; Raymond L. Newcomb, naturalist; and William M. Dunbar, ice pilot. The _Jeannette_ left San Francisco July 8, and moved slowly toward the Golden Gate amid the cheers and waving of handkerchiefs from thousands of spectators on the wharves and on Telegraph Hill. A salute of ten guns was fired from Fort Point, while a convoy of white-sailed craft of the San Francisco Yacht Club escorted her out to the broad Pacific. Pursuing her course, the _Jeannette_ made for Ounalaska, one of the Aleutian Islands, which she reached August 2. There additional stores were taken aboard, and four days later she pursued her course, to St. Michaels, Alaska, where she anchored the 12th of August. Dogs and fur clothing were purchased, and two Alaskans, Anequin and Alexai, were hired to accompany the expedition as dog drivers. By the 25th of August, she had reached St. Lawrence Bay, East Siberia, where Lieutenant De Long learned that a ship supposed to be the _Vega_ had gone south in June. She then rounded East Cape and touched at Cape Serdze, from which point Lieutenant De Long sent his last letter home. Captain Barnes of the American whale bark _Sea Breeze_ saw the _Jeannette_ under full sail and steam, on the 2d of September, 1879, about fifty miles south of Herald Island; on the 3d of September she was sighted by Captain Kelley of the bark _Dawn_; and at about the same time Captain Bauldry of the _Helen Mar_ and several other whalers saw smoke from the _Jeannette’s_ smoke-stack in range of Herald Island. She was standing north. These were the last tidings heard of the expedition by the outside world for over two years. On the 5th of September, the _Jeannette_, having boldly entered the ice in an attempt to push through and winter at Herald Island or Wrangell Land, was beset and never again left the ice-pack, but drifted at the mercy of this formidable foe, until she was crushed, and finally sank many months afterward. Hoping against hope that a release would come, first in the fall with the promise of Indian summer, then in the spring with the breaking up of the ice-pack, Captain De Long saw the weeks and months glide by, and followed the complicated drift of the _Jeannette_, as she coquetted with her jailer, turning and twisting in her course, suffering the constant pressure of her enemy, that hourly threatened her destruction and pursuing an uneven drift north and eastward. The daily routine during the long imprisonment was practically as follows:—
