Outings at Odd Times

by Charles C. Abbott

A wide tract of meadows that skirt the river near my home, and upon which much wealth and labor have been expended in years past, was the abode of desolation in the eyes of the sturdy settlers two hundred years ago, and so treacherous the footing in every direction—so the record runs—that the hunted bears and deer would come to a stand rather than plunge headlong into the trackless waste. With proper caution the tract was finally explored, mapped, and ditched, and now there is small chance of disaster unless the rambler is culpably negligent.

I hold that one should think kindly of a ditch. The commonly imputed repulsiveness of such a waterway is more often wanting than present, and nearly all that I have seen have teemed with interesting life. What are the brooks, indeed, that turn a poet’s head, but Nature’s own ditches? As to those of man’s creation, they need but a little time, and they will assume every function of a natural watercourse.

As I stood recently upon rising ground overlooking a pasture meadow that was brown as a nut with its carpet of dead grass, I noticed a long, straight line of weed-like growths still showing a tinge of green, as if the frost had spared a narrow strip of the exposed tract. Viewing it from other points, it was evident that a ditch had once been dug where these ranker grasses grew, and through long neglect it had finally been choked with weeds and almost obliterated. It was a delightful discovery. Armed with a spade, a hoe, and sundry tools of greater or less efficiency, I set out to explore this one-time watercourse, thinking it child’s play to move tons of matted weeds and mud. How much or how little I accomplished it matters not, but the fierce onslaught of unreasoning enthusiasm broke in the door of a zoölogical El Dorado.

Jetsam and flotsam from the yearly freshets, showers of wind-tossed autumn leaves, a forest of rank growths that revel in the mud, all had added their quota, unchecked, to the baneful work of damming the little stream, which finally had been shut from view, but, as it proved, not wholly overcome. A narrow, tube-like channel still remained, with the mud below and upon each side almost as yielding as the water itself. Here fish, turtles, and creeping things innumerable not only lived, but wended their darksome way from the open ditch not far off to the basins of the sparkling springs at the hill-foot. I had discovered a hidden highway, a busy thoroughfare that teemed with active life.

Except with those forms of life that by their construction are solely adapted to a subterranean existence, as the earth-worm, or to a fixed one, as the oyster, we commonly associate our familiar forms of wild animals with unlimited freedom of movement, and suppose that they have the wide world before them to wander where they list; and, again, that of creatures as high in the scale as fishes and upward the supposition is that in proportion to their freedom of movement are their chances of escape when pursued. Now these, like many another common impression, are true in a general way, but fairly bristle with exceptions. For instance, there are many extremely sluggish fishes, yet what creatures are more agile and swift than the minnows in our brooks? And there are fishes that can walk on the mud with their bodies entirely out of the water. Dr. Gunther tells us that “the Barramunda is said to be in the habit of going on land, or at least on mud-flats; and this assertion appears to be borne out by the fact that it is provided with a lung.... It is also said to make a grunting noise, which may be heard at night for some distance.”

So far Australia; and now what of New Jersey mud-flats and the fishes that frequent them? As I continued to explore the hidden highway of snakes, turtles, and fishes, I found in almost every spadeful of mud and matted weeds one or more brown-black fishes that were as much at home as ever an earth-worm in the firmer soil. Blunt-headed, cylindrical, thick-set, and strongly finned, these fishes were built to overcome many an obstacle that would prove insuperable to almost any other. How, indeed, they burrowed even in soft mud is not readily explained; that they do advance head-foremost into such a trackless mass is unquestionable.

How long these mud-fish tarry in such spots I can not say, but during the long-dry summer this one-time ditch must be almost as dry as dust, and then probably it is quite forsaken; but their powers of endurance may be underestimated. Of the African “Lepidosiren” Dr. Gunther remarks: “During the dry season specimens living in shallow waters which periodically dry up form a cavity in the mud, the inside of which they line with a protecting capsule of mucus, and from which they emerge again when the rains refill the pools inhabited by them. While they remain in this torpid state of existence the clay balls containing them are frequently dug out, and if the capsules are not broken the fishes imbedded in them can be transported to Europe, and released by being immersed in slightly tepid water.”

The many mud-fishes that I tossed upon the dead grass had clearly no liking for an atmospheric bath, and floundered about in a typical fish-like fashion; but not for long. Finding no open water near, they became quiet at once when by chance they fell into some little cavity of the mud masses from which the water had not drained. All such fortunate fishes seemed quite at ease, and remained motionless where their good luck had brought them; but the moment I attempted to pick them up they twisted like eels upon their muddy beds, and buried themselves head-foremost with a rapidity that was simply marvelous. This perhaps is what the reader would expect, but it struck me as a little strange, because, when I startled others of these fishes as they rested among the weeds or on the sand of the open ditches, they usually gave a twist of the tail that dug a pit in a twinkling, and in this the fishes sank, tail-foremost.

When in the mud these curious minnows can only feel their way, and if they procure any food at all at such a time it can only be such objects as come directly in contact with their mouths. But how different is it when these same fishes are in open water! They are expert fly-catchers then, and capture many an insect that would be lost to a trout or chub. They have not to wait for flies to fall upon the surface, but seize those that happen to alight upon overhanging blades of grass or any projecting twig. The distance that they will leap above the water is remarkable, the spring being preceded by a withdrawal from the object and a slight sigmoid curvature of the body, involving, I suppose, the same principle as that of a short run before jumping. Mud minnows two inches in length, which I kept in an aquarium, were proved capable of leaping above the water a distance equal to twice their length; but others, much larger, could not or would not leap so far. So far as my own observations extend, exhibitions of this leaping from the water to seize insects are not often witnessed, and it was my aquarium studies that led me to watch these fishes closely when in the muddy ponds and ditches. Once, when so engaged, I saw the following: One of these minnows, little more than an inch in length, sighted an insect at the same moment that it was seen by a huge female minnow more than thrice the other’s length. The little fellow had all the advantage, however, as it was much nearer the fly, and at the proper instant away it leaped, caught the insect, and sank back—but not to the water. That hungry ogress was willing to be fed by proxy, as it were, and, permitting the little minnow to swallow the fly, she promptly swallowed both.

Tiring of the fish at last, and having long since wearied of reopening the ditch, I turned my attention to the other creatures that I had unearthed. Among them were four species of turtles, each represented by several individuals. One of these was the Muhlenberg tortoise, the rarest of American chelonians. Probably just here, over a few hundred acres of the Delaware meadows, there are more of them than in the whole world besides. The fact of their great rarity makes them the more interesting to a naturalist; but to-day they proved exceedingly stupid, far more so than the others, which in a mild way resented my interference, and pranced over the dead grass quite energetically, reaching the nearest open ditch in good time, and to my surprise they all seemed governed by a sense of direction. They went but little if any out of their way. Not so with the “Muhlenbergs”; they seemed dazed for a long time, and finally, after much looking about, they started, the four together, in the wrong direction, and would have had a weary journey to reach open water. Again and again I faced them about, but they would not go as I wished. Such obstinate turtles I had never seen before, and I almost felt convinced that they were impelled by some common impression very different from that which actuated the others. As is often the case, I was all at sea in my efforts to interpret their purposes. Letting them alone, they waddled through the grass for a few yards only, when they reached little pools that met all their needs.
