"It were better had we done this more early, for a light might now prove dangerous, should we really have altered the course in this intense darkness. There is no remedy, however, and the risk must be taken. I will first try the lead again." A cast was made, and the result was two and a half fathoms of water. "Put the helm down!" cried Paul, springing to the sheet: "lose not a moment, but down with the helm!" The boat did not work freely under her imperfect sail and with the roof she carried, and a moment of painful anxiety succeeded. Paul managed, however, to get a part of the sail aback, and he felt more secure. "The boat has stern-way: shift the helm, Mr. Sharp." This was done, the yard was dipped, and the two young men felt a relief almost equal to that they had experienced on clearing the inlet, when they found the launch again drawing ahead, obedient to her rudder. "We are near something, reef or shore," said Paul, standing with the lead-line in his hand, in readiness to heave. "I think it can hardly be the first, as we hear no Arabs." Waiting a few minutes, he hove the lead, and, to his infinite joy, got three fathoms fairly. "That is good news. We are hauling off the danger, whatever it may be," he said, as he felt the mark: "and now for the compass." Saunders was called, a light was struck, and the compasses were both examined. These faithful but mysterious guides, which have so long served man while they have baffled all his ingenuity to discover the sources of their power, were, as usual, true to their governing principle. The boat was heading north-north-west; the wind was at north-east, and before they tacked they had doubtless been standing directly for the beach, from which they could not have been distant a half quarter of a mile, if so much. A few more minutes would have carried them into the breakers, capsized the boat, and most probably drowned all below the roof, if not those on it. Paul shuddered as these facts forced themselves on his attention, and he determined to stand on his present course for two hours, when daylight would render his return towards the land without danger. "This is the trade," he said, "and it will probably stand. We have a current to contend with, as well as a head-wind; but I think we can weather the cape by morning, when we can get a survey of the wreck by means of the glass. If we discover nothing, I shall bear up at once for the Cape de Verds."
