The Nature Books of Henry David Thoreau – 6 Titles in One Volume (Illustrated Edition). Henry David Thoreau
the smallest, as a small continent and integral portion of the globe. I have a fancy for building my hut on one. Even a bare, grassy isle, which I can see entirely over at a glance, has some undefined and mysterious charm for me. There is commonly such a one at the junction of two rivers, whose currents bring down and deposit their respective sands in the eddy at their confluence, as it were the womb of a continent. By what a delicate and far-stretched contribution every island is made! What an enterprise of Nature thus to lay the foundations of and to build up the future continent, of golden and silver sands and the ruins of forests, with ant-like industry! Pindar gives the following account of the origin of Thera, whence, in after times, Libyan Cyrene was settled by Battus. Triton, in the form of Eurypylus, presents a clod to Euphemus, one of the Argonauts, as they are about to return home.
"He knew of our haste,
And immediately seizing a clod
With his right hand, strove to give it
As a chance stranger's gift.
Nor did the hero disregard him, but leaping on the shore,
Stretching hand to hand,
Received the mystic clod.
But I hear it sinking from the deck,
Go with the sea brine
At evening, accompanying the watery sea.
Often indeed I urged the careless
Menials to guard it, but their minds forgot.
And now in this island the imperishable seed of spacious Libya
Is spilled before its hour."
It is a beautiful fable, also related by Pindar, how Helius, or the Sun, looked down into the sea one day,—when perchance his rays were first reflected from some increasing glittering sandbar,—and saw the fair and fruitful island of Rhodes
"springing up from the bottom, Capable of feeding many men, and suitable for flocks;
and at the nod of Zeus,
"The island sprang from the watery
Sea; and the genial Father of penetrating beams,
Ruler of fire-breathing horses, has it."
The shifting islands! who would not be willing that his house should be undermined by such a foe! The inhabitant of an island can tell what currents formed the land which he cultivates; and his earth is still being created or destroyed. There before his door, perchance, still empties the stream which brought down the material of his farm ages before, and is still bringing it down or washing it away,—the graceful, gentle robber!
Not long after this we saw the Piscataquoag, or Sparkling Water, emptying in on our left, and heard the Falls of Amoskeag above. Large quantities of lumber, as we read in the Gazetteer, were still annually floated down the Piscataquoag to the Merrimack, and there are many fine mill privileges on it. Just above the mouth of this river we passed the artificial falls where the canals of the Manchester Manufacturing Company discharge themselves into the Merrimack. They are striking enough to have a name, and, with the scenery of a Bashpish, would be visited from far and near. The water falls thirty or forty feet over seven or eight steep and narrow terraces of stone, probably to break its force, and is converted into one mass of foam. This canal-water did not seem to be the worse for the wear, but foamed and fumed as purely, and boomed as savagely and impressively, as a mountain torrent, and, though it came from under a factory, we saw a rainbow here. These are now the Amoskeag Falls, removed a mile down-stream. But we did not tarry to examine them minutely, making haste to get past the village here collected, and out of hearing of the hammer which was laying the foundation of another Lowell on the banks. At the time of our voyage Manchester was a village of about two thousand inhabitants, where we landed for a moment to get some cool water, and where an inhabitant told us that he was accustomed to go across the river into Goffstown for his water. But now, as I have been told, and indeed have witnessed, it contains fourteen thousand inhabitants. From a hill on the road between Goffstown and Hooksett, four miles distant, I have seen a thunder-shower pass over, and the sun break out and shine on a city there, where I had landed nine years before in the fields; and there was waving the flag of its Museum, where "the only perfect skeleton of a Greenland or river whale in the United States" was to be seen, and I also read in its directory of a "Manchester Athenaeum and Gallery of the Fine Arts."
According to the Gazetteer, the descent of Amoskeag Falls, which are the most considerable in the Merrimack, is fifty-four feet in half a mile. We locked ourselves through here with much ado, surmounting the successive watery steps of this river's staircase in the midst of a crowd of villagers, jumping into the canal to their amusement, to save our boat from upsetting, and consuming much river-water in our service. Amoskeag, or Namaskeak, is said to mean "great fishing-place." It was hereabouts that the Sachem Wannalancet resided. Tradition says that his tribe, when at war with the Mohawks, concealed their provisions in the cavities of the rocks in the upper part of these falls. The Indians, who hid their provisions in these holes, and affirmed "that God had cut them out for that purpose," understood their origin and use better than the Royal Society, who in their Transactions, in the last century, speaking of these very holes, declare that "they seem plainly to be artificial." Similar "pot-holes" may be seen at the Stone Flume on this river, on the Ottaway, at Bellows' Falls on the Connecticut, and in the limestone rock at Shelburne Falls on Deerfield River in Massachusetts, and more or less generally about all falls. Perhaps the most remarkable curiosity of this kind in New England is the well-known Basin on the Pemigewasset, one of the head-waters of this river, twenty by thirty feet in extent and proportionably deep, with a smooth and rounded brim, and filled with a cold, pellucid, and greenish water. At Amoskeag the river is divided into many separate torrents and trickling rills by the rocks, and its volume is so much reduced by the drain of the canals that it does not fill its bed. There are many pot-holes here on a rocky island which the river washes over in high freshets. As at Shelburne Falls, where I first observed them, they are from one foot to four or five in diameter, and as many in depth, perfectly round and regular, with smooth and gracefully curved brims, like goblets. Their origin is apparent to the most careless observer. A stone which the current has washed down, meeting with obstacles, revolves as on a pivot where it lies, gradually sinking in the course of centuries deeper and deeper into the rock, and in new freshets receiving the aid of fresh stones, which are drawn into this trap and doomed to revolve there for an indefinite period, doing Sisyphus-like penance for stony sins, until they either wear out, or wear through the bottom of their prison, or else are released by some revolution of nature. There lie the stones of various sizes, from a pebble to a foot or two in diameter, some of which have rested from their labor only since the spring, and some higher up which have lain still and dry for ages,—we noticed some here at least sixteen feet above the present level of the water,—while others are still revolving, and enjoy no respite at any season. In one instance, at Shelburne Falls, they have worn quite through the rock, so that a portion of the river leaks through in anticipation of the fall. Some of these pot-holes at Amoskeag, in a very hard brown-stone, had an oblong, cylindrical stone of the same material loosely fitting them. One, as much as fifteen feet deep and seven or eight in diameter, which was worn quite through to the water, had a huge rock of the same material, smooth but of irregular form, lodged in it. Everywhere there were the rudiments or the wrecks of a dimple in the rock; the rocky shells of whirlpools. As if by force of example and sympathy after so many lessons, the rocks, the hardest material, had been endeavoring to whirl or flow into the forms of the most fluid. The finest workers in stone are not copper or steel tools, but the gentle touches of air and water working at their leisure with a liberal allowance of time.
Not only have some of these basins been forming for countless ages, but others exist which must have been completed in a former geological period. In deepening the Pawtucket Canal, in 1822, the workmen came to ledges with pot-holes in them, where probably was once the bed of the river, and there are some, we are told, in the town of Canaan in this State, with the stones still in them, on the height of land between the Merrimack and Connecticut, and nearly a thousand feet above these rivers, proving that the mountains and the rivers have changed places. There lie the stones which completed their revolutions perhaps before thoughts began to revolve in the brain of man. The periods of Hindoo and Chinese history,
