"Is there not an under current here, Karl?" said Jenkins, attempting to appear composed.
"Ja," replied Vanderhoek; "see, there is von gut sign. The meer-weeds are drifting to the east; and see, there is von piece of the wreck moving from the west."
I looked down, and saw the edge of a piece of black timber making its appearance within the verge of the rim of the bell; but, in consequence of the small angle afforded by our pent-up position, we could not observe more than two inches of it. Large bushes of confusedly entangled sea-weed were brushing past, and, as they stuck about the rim, darkened the interior so much that we could scarcely see each other. These seemed of but small importance to Jenkins, who was evidently still unsatisfied with the working of the pumps, and got upon his feet to examine into the cause of their irregular and interrupted action. It struck me, at this time, that Jenkins' question about the current had more meaning in it than was made apparent to me: I suspected that he entertained fears that the air tubes had got entangled in some way with the bell chain. His efforts did not seem to produce any greater regularity of action in the tubes; the whizzing noise continued every now and then to be interrupted; at one time, it stopped altogether for about a minute. The machinery was working reluctantly, and with a struggling difficulty that was apparent to the eye and ear; but other proofs of a more decided and fearful kind were awaiting us. I felt a painful load at my breast, as if I wanted air; my respiration became quick and unsatisfactory; a swimming of the head came over me; I could scarcely see my companions without great effort to fix my wavering vision. The darkness at the mouth of the bell continued to increase; the piece of the wreck was moving slowly under us; the weeds were increasing. I could perceive that Vanderhoek was also labouring for breath; Jenkins, relinquishing his efforts at the air tube mouths, turned, looked wildly at his neighbour, and, staggering down upon the bench, struggled to get hold of the hammer, which, when he grasped it tremblingly, fell out of his hands down into the bottom of the sea.
"In the name of God! what is the meaning of all this, Jenkins?" I cried, in a voice that was choked for want of air.
