and swimmers cramp; and all this before coming within bullet-range of any hospitalities on the other shore. But I knew the folly of most alarms about reptiles and fishes; man's imagination peoples the water with many things which do not belong there, or prefer to keep out of his way, if they do; fevers and congestions were the surgeon's business, and I always kept people to their own department; cramp and exhaustion were dangers I could measure, as I had often done; bullets were a more substantial danger, and I must take the chance,—if a loon could dive at the flash, why not I? If I were once ashore, I should have to cope with the Rebels on their own ground, which they knew better than I; but the water was my ground, where I, too, had been at home from boyhood.
I swam as swiftly and softly as I could, although it seemed as if water never had been so still before. It appeared impossible that anything uncanny should hide beneath that lovely mirror; and yet when some floating wisp of reeds suddenly coiled itself around my neck, or some unknown thing, drifting deeper, coldly touched my foot, it gave that undefinable sense of shudder which every swimmer knows, and which especially appeals to the imagination by night. Sometimes a slight sip of brackish water would enter my lips,—for I naturally tried to swim as low as possible,—and then would follow a slight gasping and contest against choking, such as seemed to me a perfect convulsion; for I suppose the tendency to choke and sneeze is always enhanced by the circumstance that one's life may depend on keeping still, just as yawning becomes irresistible where to yawn would be social ruin, and just as one is sure to sleep in church, if one sits in a conspicuous pew. At other times, some unguarded motion would create a splashing which seemed, in the tension of my senses, to be loud enough to be heard at Richmond, although it really mattered not, since there are fishes in those rivers which make as much noise on special occasions as if they were misguided young whales.
As I drew near the opposite shore, the dark causeway projected more and more distinctly, to my fancy at least, and I swam more softly still, utterly uncertain as to how far, in the stillness of air and water, my phosphorescent course could be traced by eye or ear. A slight ripple would have saved me from observation, I was more than ever sure, and I would have whistled for a fair wind as eagerly as any sailor, but that my breath was worth more than anything it was likely to bring. The water became smoother and smoother, and nothing broke the dim surface except a few clomps of rushes and my unfortunate head. The outside of this member gradually assumed to its inside a gigantic magnitude; it had always annoyed me at the hatter's from a merely animal bigness, with no commensurate contents to show for it, and now I detested it more than ever. A physical fooling of turgescence and congestion in that region, such as swimmers often feel, probably increased the impression. I thought with envy of the Aztec children, of the headless horseman of Sleepy Hollow, of Saint Somebody with his head tucked under his arm. Plotinus was less ashamed of his whole body than I of this inconsiderate and stupid appendage. To be sure, I might swim for a certain distance under water. But that accomplishment I had reserved for a retreat, for I knew that the longer I stayed down the more surely I should have to snort like a walrus when I came up again, and to approach an enemy with such a demonstration was not to be thought of.
Suddenly a dog barked. We had certain information that a pack of hounds was kept at a Rebel station a few miles off, on purpose to hunt runaways, and I had heard from the negroes almost fabulous accounts of the instinct of these animals. I knew, that, although water baffled their scent, they yet could recognize in some manner the approach of any person across water as readily as by land; and of the vigilance of all dogs by night every traveller among Southern plantations has ample demonstration. I was now so near that I could dimly see the figures of men moving to and fro upon the end of the causeway, and could hear the dull knock, when one struck his foot against a piece of timber.
As my first object was to ascertain whether there were sentinels at that time at that precise point, I saw that I was approaching the end of my experiment. Could I have once reached the causeway unnoticed, I could have lurked in the water beneath its projecting timbers, and perhaps made my way along the main shore, as I had known fugitive slaves to do, while coming from that side. Or had there been any ripple on the water, to confuse the aroused and watchful eyes, I could have made a circuit and approached the causeway at another point, though I had already satisfied myself that there was only a narrow channel on each side of it, even at high tide, and not, as on our side, a broad expanse of water. Indeed, this knowledge alone was worth all the trouble I had taken, and to attempt much more than this, in the face of a curiosity already roused, would have been a waste of future opportunities. I could try again, with the benefit of this new knowledge, on a point where the statements of the negroes had always been contradictory.
Resolving, however, to continue the observation a very little longer, since the water felt much warmer than I had expected, and there was no sense of chill or fatigue, I grasped at some wisps of straw or rushes that floated near, gathering them round my face a little, and then, drifting nearer the wharf in what seemed a sort of eddy, was able, without creating further alarm, to make some additional observations on points which it is not best now to particularize. Then, turning my back upon the mysterious shore which had thus far lured me, I sank softly below the surface and swam as far as I could under water.
During this unseen retreat, I heard, of course, all manner of gurglings and hollow reverberations, and could fancy as many rifle-shots as I pleased. But on rising to the surface all seemed quiet, and even I did not create as much noise as I should have expected. I was now at a safe distance, since they were always chary of showing their boats, and they would hardly take personally to the water. What with absorbed attention first, and this submersion afterwards, I had lost all my bearings but the stars, having been long out of sight of my original point of departure. However, the difficulties of the return were nothing; making a slight allowance for the flood-tide, which could not yet have turned, I should soon regain the place I had left. So I struck out freshly against the smooth water, feeling just a little stiffened by the exertion, and with an occasional chill running up the back of the neck, but with no nips from sharks, no nudges from alligators, and not a symptom of fever-and-ague.
Time I could not, of course, measure,—one never can, in a novel position; but, after a reasonable amount of swimming, I began to look, with a natural interest, for the pier which I had quitted. I noticed, with some solicitude, that the woods along the friendly shore made one continuous shadow, and that the line of low bushes on the long causeway could scarcely be relieved against them, yet I knew where they ought to be, and the more doubtful I felt about it, the more I put down my doubts, as if they were unreasonable children. One can scarcely conceive of the alteration made in familiar objects by bringing the eye as low as the horizon, especially by night; to distinguish foreshortening is impossible, and every low near object is equivalent to one higher and more remote. Still I had the stars; and soon my eye, more practised, was enabled to select one precise line of bushes as that which marked the causeway, and for which I must direct my course.
As I swam steadily, but with some sense of fatigue, towards this phantom-line, I found it difficult to keep my faith steady and my progress true; everything appeared to shift and waver, in the uncertain light. The distant trees seemed not trees, but bushes, and the bushes seemed not exactly bushes, but might, after all, be distant trees. Could I be so confident, that, out of all that low stretch of shore, I could select the one precise point where the friendly causeway stretched its long arm to receive me from the water? How easily (some tempter whispered at my ear) might one swerve a little, on either side, and be compelled to flounder over half a mile of oozy marsh on an ebbing tide, before reaching our own shore and that hospitable volley of bullets with which it would probably greet me! Had I not already (thus the tempter continued) been swimming rather unaccountably far, supposing me on a straight track for that inviting spot where my sentinels and my drapery were awaiting my return?
Suddenly I felt a sensation as of fine ribbons drawn softly across my person, and I found myself among some rushes. But what business had rushes there, or I among them? I knew that there was not a solitary spot of shoal in the deep channel where I supposed myself swimming, and it was plain in an instant that I had somehow missed my course, and must be getting among the marshes. I felt confident, to be sure, that I could not have widely erred, but was guiding my course for the proper
