But afterwards that immense extent of water disappeared under enormous fields of ice, upon which hummocks rose up as regularly as a crystallisation of the same substance. Shandon had the steam put on, and up to the 11th of May the _Forward_ wound amongst the sinuous rocks, leaving the print of a track on the sky, caused by the black smoke from her funnels. But new obstacles were soon encountered; the paths were getting closed up in consequence of the incessant displacement of the floating masses; at every minute a failure of water in front of the _Forward's_ prow became imminent, and if she had been nipped it would have been difficult to extricate her. They all knew it, and thought about it. On board this vessel, without aim or known destination, foolishly seeking to advance towards the north, some symptoms of hesitation were manifested amongst those men, accustomed to an existence of danger; many, forgetting the advantages offered, regretted having ventured so far, and already a certain demoralisation prevailed in their minds, still more increased by Clifton's fears, and the idle talk of two or three of the leaders, such as Pen, Gripper, Warren, and Wolston. To the uneasiness of the crew were joined overwhelming fatigues, for on the 12th of May the brig was closed in on every side; her steam was powerless, and it was necessary to force a road through the ice-fields. The working of the saws was very difficult in the floes, which measured from six to seven feet in thickness. When two parallel grooves divided the ice for the length of a hundred feet, they had to break the interior part with hatchets or handspikes; then took place the elongation of the anchors, fixed in a hole by means of a thick auger; afterwards the working of the capstan began, and in this way the vessel was hauled over. The greatest difficulty consisted in driving the smashed pieces under the floes in order to open up a free passage for the ship, and to thrust them away they were compelled to use long iron-spiked poles. At last, what with the working of the saws, the hauling, the capstan and poles, incessant, dangerous, and forced work, in the midst of fogs or thick snow, the temperature relatively low, ophthalmic suffering and moral uneasiness, all contributed to discourage the crew, and react on the men's imagination. When sailors have an energetic, audacious, and convinced man to do with, who knows what he wants, where he is bound for, and what end he has in view, confidence sustains them in spite of everything. They make one with their chief, feeling strong in his strength, and quiet in his tranquillity; but on the brig it was felt that the commander was not sure of himself, that he hesitated before his unknown end and destination. In spite of his energetic nature, his weakness showed itself in his changing orders, incomplete manoeuvres, stormy reflections, and a thousand details which could not escape the notice of the crew.
