Great trees had in their youth fallen far forward, undermined by the water, then slowly taken a new reach upward and stretched forth great feet and hands of roots, palms pressing against the mud, curved backs and thews of shoulders braced against one another and the drag of the tides. Little by little the old prostrate trunks were entirely obliterated by this fantastic network. There were no fine fibers or rootlets here; only great beams and buttresses, bridges and up-ended spirals, grown together or spreading wide apart. Root merged with trunk, and great boles became roots and then boles again in this unreasonable land. For here, in place of damp, black mold and soil, water alternated with dark-shadowed air; and so I was able for a time to live the life of a root, resting quietly among them, watching and feeling them, and moving very slowly, with no thought of time, as roots must.

I liked to wait until the last ripple had lapped against the sand beneath, and then slip quietly in from the margin of the jungle and perch—like a great tree-frog—on some convenient shelf. Seumas and Brigid would have enjoyed it, in spite of the fact that the Leprechauns seemed to have just gone. I found myself usually in a little room, walled with high-arched, thin sheets of living roots, some of which would form solid planks three feet wide and twelve long, and only an inch or two in thickness. These were always on edge, and might be smooth and sheer, or suddenly sprout five stubby, mittened fingers, or pairs of curved and galloping legs—and this thought gave substance to the simile which had occurred again and again: these trees reminded me of centaurs with proud, upright man torsos, and great curved backs. In one, a root dropped down and rested on the back, as a centaur who turns might rest his hand on his withers.

When I chanced upon an easy perch, and a stray idea came to mind, I squatted or sat or sprawled, and wrote, and strange things often happened to me. Once, while writing rapidly on a small sheet of paper, I found my lines growing closer and closer together until my fingers cramped, and the consciousness of the change overlaid the thoughts that were driving hand and pen. I then realized that, without thinking, I had been following a succession of faint lines, cross-ruled on my white paper, and looking up, I saw that a leaf-filtered opening had reflected strands of a spider-web just above my head, and I had been adapting my lines to the narrow spaces, my chirography controlled by cobweb shadows.

The first unreality of the roots was their rigidity. I stepped from one slender tendon of wood to the next, expecting a bending which never occurred. They might have been turned to stone, and even little twigs resting on the bark often proved to have grown fast. And this was the more unexpected because of the grace of curve and line, fold upon fold, with no sharp angles, but as full of charm of contour as their grays and olives were harmonious in color. Photographs showed a little of this; sketches revealed more; but the great splendid things themselves, devoid of similes and human imagination, were soul-satisfying in their simplicity.

I seldom sat in one spot more than a few minutes, but climbed and shifted, tried new seats, couches, perches, grips, sprawling out along the tops of two parallel monsters, or slipping under their bellies, always finding some easy way to swing up again. Two openings just permitted me to squeeze through, and I wondered whether, in another year, or ten, or fifty, the holes would have grown smaller. I became imbued with the quiet joy of these roots, so that I hated to touch the ground. Once I stepped down on the beach after something I had dropped, and the soft yielding of the sand was so unpleasant that I did not afterwards leave this strange mid-zone until I had to return. Unlike Antæus, I seemed to gain strength and poise by disassociation with the earth.

Here and there were pockets in the folds of the sweeping draperies, and each pocket was worth picking. When one tried to paint the roots, these pockets seemed made expressly to take the place of palette cups, except that now and then a crab resented the infusion of Hooker's green with his Vandyke brown puddle, and seized the end of the brush. The crabs were worthy tenants of such strange architecture, with comical eyes twiddling on the end of their stalks, and their white-mittened fists feinting and threatening as I looked into their little dark rain or tide-pools.

I found three pockets on one wall, which seemed as if they must have been "salted" for my benefit; and in them, as elsewhere on my beach, the two extremes of life met. The topmost one, curiously enough, contained a small crab, together with a large water-beetle at the farther end. Both seemed rather self-conscious, and there was no hint of fraternizing. The beetle seemed to be merely existing until darkness, when he could fly to more water and better company; and the crab appeared to be waiting for the beetle to go.

The next pocket was a long, narrow, horizontal fold, and I hoped to find real excitement among its aquatic folk; but to my surprise it had no bottom, but was a deep chute or socket, opening far below to the sand. However, this was not my discovery, and I saw dimly a weird little head looking up at me—a gecko lizard, which called this crevice home and the crabs neighbors. I hailed him as the only other backboned friend who shared the root-world with me, and then listened to a high, sweet tone, which came forth in swinging rhythm. It took some time for my eyes to become accustomed to the semi-darkness, and then I saw what the gecko saw—a big yellow-bodied fly humming in this cavern, and swinging in a small orbit as she sang. Now and then she dashed out past me and hovered in mid-air, when her note sank to a low, dull hum. Back again, and the sound rose and fell, and gained ten times in volume from the echo or reverberations. Each time she passed, the little lizard licked his chops and swallowed—a sort of vicarious expression of faith or desire; or was he in a Christian Science frame of mind, saying, "My, how good that fly tasted!" each time the dipteron passed? The fly was just as inexplicable, braving danger and darkness time after time, to leave the sunshine and vibrate in the dusk to the enormously magnified song of its wings.

With eyes that had forgotten the outside light, I leaned close to the opening and rested my forehead against the lichens of the wall of wood. The fly was frightened away, the gecko slipped lower, seemingly without effort, and in a hollowed side of the cavernous root I saw a mist, a quivering, so tenuous and indistinct that at first it might have been the dancing of motes. I saw that they were living creatures—the most delicate of tiny crane-flies—at rest looking like long-legged mosquitoes. Deep within this root, farther from the light than even the singing fly had ventured, these tiny beings whirled madly in mid-air—subterranean dervishes, using up energy for their own inexplicable ends, of which one very interested naturalist could make nothing.

Three weeks afterward I happened to pass at high tide in the canoe and peered into this pocket. The gecko was where geckos go in the space of three weeks, and the fly also had vanished, either within or without the gecko. But the crane-flies were still there: to my roughly appraising eyes the same flies, doing the same dance in exactly the same place. Three weeks later, and again I returned, this time intentionally, to see whether the dance still continued; and it was in full swing. That same night at midnight I climbed down, flashed a light upon them, and there they whirled and vibrated, silently, incredibly rapid, unceasingly.
