If there ever was a stream cradled in the rocks, detained lovingly by them, held and fondled in a rocky lap or tossed in rocky arms, that stream is the Rondout. Its course for several miles from its head is over the stratified rock, and into this it has worn a channel that presents most striking and peculiar features. Now it comes silently along on the top of the rock, spread out and flowing over that thick, dark green moss that is found only in the coldest streams; then drawn into a narrow canal only four or five feet wide, through which it shoots, black and rigid, to be presently caught in a deep basin with shelving, overhanging rocks, beneath which the phœbe-bird builds in security, and upon which the fisherman stands and casts his twenty or thirty feet of line without fear of being thwarted by the brush; then into a black, well-like pool, ten or fifteen feet deep, with a smooth, circular wall of rock on one side worn by the water through long ages; or else into a deep, oblong pocket, into which and out of which the water glides without a ripple. The surface rock is a coarse sandstone superincumbent upon a lighter-colored conglomerate that looks like Shawangunk grits, and when this latter is reached by the water it seems to be rapidly disintegrated by it, thus forming the deep excavations alluded to. My eyes had never before beheld such beauty in a mountain stream. The water was almost as transparent as the air,—was, indeed, like liquid air; and as it lay in these wells and pits enveloped in shadow, or lit up by a chance ray of the vertical sun, it was a perpetual feast to the eye,—so cool, so deep, so pure; every reach and pool like a vast spring. You lay down and drank or dipped the water up in your cup, and found it just the right degree of refreshing coldness. One is never prepared for the clearness of the water in these streams. It is always a surprise. See them every year for a dozen years, and yet, when you first come upon one, you will utter an exclamation. I saw nothing like it in the Adirondacks, nor in Canada. Absolutely without stain or hint of impurity, it seems to magnify like a lens, so that the bed of the stream and the fish in it appear deceptively near. It is rare to find even a trout stream that is not a little “off color,” as they say of diamonds, but the waters in the section of which I am writing have the genuine ray; it is the undimmed and untarnished diamond. If I were a trout, I should ascend every stream till I found the Rondout. It is the ideal brook. What homes these fish have, what retreats under the rocks, what paved or flagged courts and areas, what crystal depths where no net or snare can reach them!—no mud, no sediment, but here and there in the clefts and seams of the rock patches of white gravel,—spawning-beds ready-made.
