In the spring of 1857 Lady Franklin commenced preparations for the contemplated expedition. She was supported by some of the most distinguished Arctic officers and scientific men, and the friends of Sir John Franklin, among whom were Sir Roderick Murchison, General Sabine, Captain Collinson, and many others. To Captain M‘Clintock was offered the command; and he who had served in three previous expeditions, and to whom are principally due the results of the extraordinary journeys over the ice that have been made during the search for Franklin, cheerfully accepted the appointment, as, in his own words, being the post of honour. The next thing was to seek a suitable vessel, and fortunately the _Fox_ was in the market. Built for a yacht of some 180 tons register, with auxiliary steam-power applied to a lifting screw, the _Fox_ appeared in every way adapted for the service. She was at once purchased, and the necessary alterations and fortifying commenced; and such was the feeling of confidence in Captain M‘Clintock’s sincerity of purpose, his daring and determination, combined with eminent talent, and every qualification for command, that numbers sought the honour of serving with him. The few who were so fortunate as to be selected were soon appointed in their different capacities, and by the exertions of Lady Franklin and Captain M‘Clintock everything that could possibly conduce to the comfort or recreation of the ship’s company was supplied, and the _Fox_ was ready for sea by the end of June. We intended first to touch at some of the Danish settlements in Greenland, to purchase sledge-dogs; then to proceed to Beechey Island, and there to fill up stores from the depôt left by Sir E. Belcher. We were next to endeavour to sail down Peel Sound (supposed to be a strait), but failing by that channel, to try down Regent’s Inlet, and by the supposed Bellot Straits to reach the neighbourhood of the Great Fish River; and having in the summer of 1857 and following spring searched the adjacent country, we should return home either westward by Behring’s Straits, or by our outward route, according to circumstances. If we failed to reach King William Land or the Fish River, it was our intention to winter as near the desired position as possible, and by means of sledge journeys over the ice, to complete the search in the following spring. We hoped to finish the work in one year; but in this we were to be disappointed, as the narrative will show.
