And as the men began to work, he dashed carelessly into another stanza of his favourite ballad. I know not if you are acquainted with German; but I cannot resist the desire of gratifying my own ears with a repetition of the sounds of the thrilling consonants which produced so great an effect on me on that occasion. His voice was rough and guttural:—

"Wann der Wein in Himmelsclang,
Wandelt mein Geklimper,
Sind Homer, and Ossian,
Gegen mich nur Stumper."

I would have called out to the man to cease his singing, had I not been afraid of being set down for a coward. The continued sound within prevented me from observing the motion of the bell, as it gradually swung off the deck; but the increasing novelty of my situation, as I saw myself suspended over the calm sea into which I was immediately to be plunged, fixed my attention, while it increased my nervousness. I would now have retreated, had it been in my power. The calculated knowledge of the process of submersion, and of my absolute safety under the laws of hydraulics, lost so much of its power under the reigning influence of the natural instinctive horror of being plunged into the womb of the ocean, that I thought myself on the eve of being drowned; and the same feeling I had experienced when struggling half-dead with the waters of the Thames took hold of me by anticipation. Meanwhile, the German started broken snatches of his song; the bell was gradually descending; the space of pure light between the rim and the green surface of the sea was growing every minute less and less. It was upon that decreasing circle of air that my eye was most intensely fixed; it grew brighter as the inside of the bell grew darker, till in a moment it appeared like a bright line of gold-coloured light.

"There," said Jenkins to me, in a loud tone. "That is the last glimpse. This is the most trying moment for inexperienced divers, when the last beam of day is extinguished."

I could not reply to him. The circle had disappeared; the water was below our feet; we were partially submerged. I looked up to the yolks of glass, but the light that struggled through them was so pale and sickly that I turned my eyes to the sea below me as a relief to my confined vision. We were now fast descending—one by one the gas lights were changed from their dim paleness to a green hue, the same as that of the sea below us, and, in an instant after, I heard a loud whizzing, which was produced by the displaced body of waters rushing impetuously into the void made by the descending bell. The sound made me instinctively turn my head upwards, as if I had been in the attitude of addressing the King of the heavens, whom I had left in the regions of upper air. I grew dizzy, and thought I would have fallen from the bench, down into the bottom of the sea. My nervousness made me grasp firmly the plank, as my only means of safety from what I conceived to be impending destruction. Whether that sound then ceased, or my hearing became more obtuse, I know not; but the first thing, after a few minutes, that I was conscious of was the grasp of the hand of Jenkins, who held me firm by the arm, and the guttural sounds of the German, as he still carelessly sung detached lines of his ballad. On looking up, the green lights swam in my eyes; but the whizzing sound had greatly ceased; and I directed again my gaze to the apparently bottomless element below, which was as calm as glass, and through which I saw, flying past the mouth of the bell, innumerable fishes, reflecting, as they darted off, a thousand varied hues, in the midst of the green medium through which they hurried.

The continued descent was made apparent to the eye by the progress of the rim of the bell through the water, and indicated, in another form, by the creaking sound of the crane on the lighter, which, rendered indistinct by the medium of the water, seemed to come from miles distant. Though partially recovered from the first effects of the submersion, I had no proper idea of time, and there was no mode of measuring the depth. It seemed to me as if we had descended many furlongs, though we had not got beyond ten fathoms: I could not get quit of the idea, though I arranged my thoughts in the process of calculation. Jenkins had now let go my arm, as he saw that I was able to sit without danger of falling; and the German was busy peering through his bushy eyebrows down into the deep, as if he expected soon "to see the land." I almost instinctively gazed down for the same object, and it was not without an effort at discrimination by the power of my judgment that I discovered myself seeking a vision of the bottom of the sea, as if it had been a haven for a shipwrecked mariner in distress. While my eyes were thus fixed on the waters—in which I could see nothing but the swarms of fishes flying past, or reeling in the confusion of terror—I was startled, almost to falling off the bench, by a loud reverberating clang on the side of the bell. My first impression was, that the bell had struck on a rock; and I turned fearfully to seek the eye of Jenkins. He held the large hammer in his hand with which he had given the stroke. He told me that he wanted more air, and that this was the signal to the workers of the air-pump. His eye was fixed on the air holes, with which the pipes communicated. I thought he appeared alarmed; he exchanged a look with Vanderhoek, and the eye of the latter was soon also fixed on the same spot. We were yet still descending, and the German, turning round, pointed down. I followed his finger, and saw a thick, hazy-like appearance, as if the waters were troubled, and masses of long sea-weed brushed against the rim of the bell. Vanderhoek immediately seized the hammer, rang two loud peals, and the motion downwards ceased. We hung suspended in the sea, I know not how many fathoms down. A loud hissing sound came from the air-valves; but it was every moment interrupted, as if some part of the apparatus failed in its continuous working. The eyes of both Jenkins and Vanderhoek were again intensely fixed upon the holes; it was too manifest to me that they both saw something wrong in the working of the air pumps, though they said nothing to me; and, indeed, I was so much affected by their ominous looks that I could put no question to them.

"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.
