It required more than two hours for the whale-boat of Roswell to cross the bay, and reach the margin of that vast field of ice, which was prevented from drifting into the open space only by encountering the stable rocks of the first of the group. Every eye was now turned in quest of an opening, by means of which it might be possible to get further to the eastward. One, at length, was discovered, and into it Gardiner dashed, ordering his boat's crew to stretch themselves out at their oars, though every man with him thought they were plunging into possible destruction. On the boat went, however, now sheering to starboard, now to port, to avoid projecting spurs of ice, until she had ploughed her way through a fearfully narrow, and a deviating passage, that sometimes barely permitted them to go through, until a spot was reached where the two fields which formed this strait actually came in close crushing contact with each other. Roswell took a look before and behind him, saw that his boat was safe owing to the formation of the two outlines of the respective fields, when he sprang upon the ice itself, bidding the boat-steerer to wait for him. A shout broke out of the lips of the young captain the instant he was erect on the ice. There lay the schooner, the Martha's Vineyard craft, within half a mile of him, in plain sight, and in as plain jeopardy. She was jammed, with every prospect, as Roswell thought, of being crushed, ere she could get free from the danger. Chapter XVI. "A sculler's notch in the stern he made, An oar he shaped of the bottle blade; Then sprung to his seat with a lightsome leap And launched afar on the calm, blue deep." _The Culprit Fay._ Roswell was hardly on the ice before a sound of a most portentous sort reached his ear. He knew at once that the field had been rent in twain by outward pressure, and that some new change was to occur that might release or might destroy the schooner. He was on the point of springing forward in order to join Daggett, when a call from the boat arrested his steps. "These here fields are coming together, Captain Gar'ner, and our boat will soon be crushed unless we get it out of the water."
