A little scream from Mrs. Budd, which was dutifully taken up by the maid, interrupted the speech of the latter, and every eye was turned on Mulford, as if to ask an explanation of the groaning sound that had been heard within the wreck.  The young mate comprehended only too well.  The rolling of the wreck had lifted a portion of the open hatchway above the undulating surface of the sea, and a large quantity of the pent air within the hold had escaped in a body.  The entrance of water to supply the vacuum had produced the groan.  Mulford had made new marks on the vessel’s bottom with his knife, and he stepped down to them, anxious and nearly heart-broken, to note the effect.  That one surging of the wreck had permitted air enough to escape to lower it in the water several inches.  As yet, however, the visible limits of their floating foundation had not been sufficiently reduced to attract the attention of the females; and the young man said nothing on the subject.  He thought that Jack Tier was sensible of the existence of this new source of danger, but if he were, that experienced mariner imitated his own reserve, and made no allusion to it.  Thus passed the day.  Occasionally the wreck rolled heavily, when more air escaped, the hull settling lower and lower in the water as a necessary consequence.  The little bubbles continued incessantly to rise, and Mulford became satisfied that another day must decide their fate.  Taking this view of their situation, he saw no use in reserving their food, but encouraged his companions to share the whole of what remained at sunset.  Little persuasion was necessary, and when night once more came to envelope them in darkness, not a mouthful of food or a drop of water remained to meet the necessities of the coming morn.  It had rained again for a short time, in the course of the afternoon, when enough water had been caught to allay their thirst, and what was almost of as much importance to the females now, a sufficiency of sun had succeeded to dry their clothes, thus enabling them to sleep without enduring the chilling damps that might otherwise have prevented it.  The wind had sensibly fallen, and the ground-swell was altogether gone, but Mulford was certain that the relief had come too late.  So much air had escaped while it lasted as scarce to leave him the hope that the wreck could float until morning.  The rising of the bubbles was now incessant, the crevices by which they escaped having most probably opened a little, in consequence of the pressure and the unceasing action of the currents, small as the latter were.

Just as darkness was shutting in around them for the second time, Rose remarked to Mulford that it seemed to her that they had not as large a space for their little world as when they were first placed on it.  The mate, however, successfully avoided an explanation; and when the watch was again set for the night, the females lay down to seek their repose, more troubled with apprehensions for a morrow of hunger and thirst, than by any just fears that might so well have arisen from the physical certainty that the body which alone kept them from being engulfed in the sea, could float but a few hours longer.  This night Tier kept the look-out until Jupiter reached the zenith, when Mulford was called to hold the watch until light returned.
