Leaving Beechy Cape, our expedition forced its way through the ice to Barlow's Inlet, where they narrowly escaped being frozen in for the winter. They endeavored to enter the Inlet, for the purpose of making it their winter quarters, but were prevented by the mass of _pack-ice_ at its entrance. It was on the 4th of September, 1850, when they arrived there, and after remaining seven or eight days, they abandoned the attempt to enter. On the right and left of the above picture, are seen the dark rocks at the entrance of the Inlet, and in the centre the frozen waters and the range of hills beyond. There was much smooth ice within the Inlet, and while the vessels lay anchored to the "field," officers and crew exercised and amused themselves by skating. On the left of the Inlet, (indicated by the dark conical object,) they discovered a _Cairn_ (a heap of stones with a cavity) eight or ten feet in height, which was erected by Captain Ommanny of the English Expedition then in the Polar waters. Within it he had placed two letters, for "whom it might concern." Commander De Haven also deposited a letter there. It is believed to be the only post-office in the world, free for the use of all nations. The rocks, here, presented vast fissures made by the frost; and at the foot of the cliff on the right, that powerful agent had cast down vast heaps of _debris_. From Barlow's Inlet, our Expedition moved slowly westward, battling with the ice every rood of the way, until they reached Griffin's Island, at about 96° west longitude from Greenwich. This was attained on the 11th, and was the extreme westing made by the expedition. All beyond seemed impenetrable ice; and, despairing of making any further discoveries before the winter should set in, they resolved to return home. Turning eastward, they hoped to reach Davis's Straits by the southern route, before the cold and darkness came on, but they were doomed to disappointment. Near the entrance to Wellington Channel they became completely locked in by _hummock-ice_, and soon found themselves drifting with an irresistible tide up that channel toward the pole.
