We were thus entering the State of New Hampshire on the bosom of the flood formed by the tribute of its innumerable valleys. The river was the only key which could unlock its maze, presenting its hills and valleys, its lakes and streams, in their natural order and position. The MERRIMACK, or Sturgeon River, is formed by the confluence of the Pemigewasset, which rises near the Notch of the White Mountains, and the Winnipiseogee, which drains the lake of the same name, signifying “The Smile of the Great Spirit.” From their junction it runs south seventy-eight miles to Massachusetts, and thence east thirty-five miles to the sea. I have traced its stream from where it bubbles out of the rocks of the White Mountains above the clouds, to where it is lost amid the salt billows of the ocean on Plum Island beach. At first it comes on murmuring to itself by the base of stately and retired mountains, through moist primitive woods whose juices it receives, where the bear still drinks it, and the cabins of settlers are far between, and there are few to cross its stream; enjoying in solitude its cascades still unknown to fame; by long ranges of mountains of Sandwich and of Squam, slumbering like tumuli of Titans, with the peaks of Moosehillock, the Haystack, and Kearsarge reflected in its waters; where the maple and the raspberry, those lovers of the hills, flourish amid temperate dews;—flowing long and full of meaning, but untranslatable as its name Pemigewasset, by many a pastured Pelion and Ossa, where unnamed muses haunt, tended by Oreads, Dryads, Naiads, and receiving the tribute of many an untasted Hippocrene. There are earth, air, fire, and water,—very well, this is water, and down it comes.

Such water do the gods distil,
And pour down every hill
For their New England men;
A draught of this wild nectar bring,
And I’ll not taste the spring
Of Helicon again.

Falling all the way, and yet not discouraged by the lowest fall. By the law of its birth never to become stagnant, for it has come out of the clouds, and down the sides of precipices worn in the flood, through beaver-dams broke loose, not splitting but splicing and mending itself, until it found a breathing-place in this low land. There is no danger now that the sun will steal it back to heaven again before it reach the sea, for it has a warrant even to recover its own dews into its bosom again with interest at every eve.

It was already the water of Squam and Newfound Lake and Winnipiseogee, and White Mountain snow dissolved, on which we were floating, and Smith’s and Baker’s and Mad Rivers, and Nashua and Souhegan and Piscataquoag, and Suncook and Soucook and Contoocook, mingled in incalculable proportions, still fluid, yellowish, restless all, with an ancient, ineradicable inclination to the sea.

So it flows on down by Lowell and Haverhill, at which last place it first suffers a sea change, and a few masts betray the vicinity of the ocean. Between the towns of Amesbury and Newbury it is a broad commercial river, from a third to half a mile in width, no longer skirted with yellow and crumbling banks, but backed by high green hills and pastures, with frequent white beaches on which the fishermen draw up their nets. I have passed down this portion of the river in a steamboat, and it was a pleasant sight to watch from its deck the fishermen dragging their seines on the distant shore, as in pictures of a foreign strand. At intervals you may meet with a schooner laden with lumber, standing up to Haverhill, or else lying at anchor or aground, waiting for wind or tide; until, at last, you glide under the famous Chain Bridge, and are landed at Newburyport. Thus she who at first was “poore of waters, naked of renowne,” having received so many fair tributaries, as was said of the Forth,

“Doth grow the greater still, the further downe;
Till that abounding both in power and fame,
She long doth strive to give the sea her name”;

or if not her name, in this case, at least the impulse of her stream. From the steeples of Newburyport you may review this river stretching far up into the country, with many a white sail glancing over it like an inland sea, and behold, as one wrote who was born on its head-waters, “Down out at its mouth, the dark inky main blending with the blue above. Plum Island, its sand ridges scolloping along the horizon like the sea-serpent, and the distant outline broken by many a tall ship, leaning, still, against the sky.”

Rising at an equal height with the Connecticut, the Merrimack reaches the sea by a course only half as long, and hence has no leisure to form broad and fertile meadows, like the former, but is hurried along rapids, and down numerous falls, without long delay. The banks are generally steep and high, with a narrow interval reaching back to the hills, which is only rarely or partially overflown at present, and is much valued by the farmers. Between Chelmsford and Concord, in New Hampshire, it varies from twenty to seventy-five rods in width. It is probably wider than it was formerly, in many places, owing to the trees having been cut down, and the consequent wasting away of its banks. The influence of the Pawtucket Dam is felt as far up as Cromwell’s Falls, and many think that the banks are being abraded and the river filled up again by this cause. Like all our rivers, it is liable to freshets, and the Pemigewasset has been known to rise twenty-five feet in a few hours. It is navigable for vessels of burden about twenty miles; for canal-boats, by means of locks, as far as Concord in New Hampshire, about seventy-five miles from its mouth; and for smaller boats to Plymouth, one hundred and thirteen miles. A small steamboat once plied between Lowell and Nashua, before the railroad was built, and one now runs from Newburyport to Haverhill.

Unfitted to some extent for the purposes of commerce by the sand-bar at its mouth, see how this river was devoted from the first to the service of manufactures. Issuing from the iron region of Franconia, and flowing through still uncut forests, by inexhaustible ledges of granite, with Squam, and Winnipiseogee, and Newfound, and Massabesic Lakes for its mill-ponds, it falls over a succession of natural dams, where it has been offering its privileges in vain for ages, until at last the Yankee race came to improve them. Standing at its mouth, look up its sparkling stream to its source,—a silver cascade which falls all the way from the White Mountains to the sea,—and behold a city on each successive plateau, a busy colony of human beaver around every fall. Not to mention Newburyport and Haverhill, see Lawrence, and Lowell, and Nashua, and Manchester, and Concord, gleaming one above the other. When at length it has escaped from under the last of the factories, it has a level and unmolested passage to the sea, a mere waste water, as it were, bearing little with it but its fame; its pleasant course revealed by the morning fog which hangs over it, and the sails of the few small vessels which transact the commerce of Haverhill and Newburyport. But its real vessels are railroad cars, and its true and main stream, flowing by an iron channel farther south, may be traced by a long line of vapor amid the hills, which no morning wind ever disperses, to where it empties into the sea at Boston. This side is the louder murmur now. Instead of the scream of a fish-hawk scaring the fishes, is heard the whistle of the steam-engine, arousing a country to its progress.

This river too was at length discovered by the white man, “trending up into the land,” he knew not how far, possibly an inlet to the South Sea. Its valley, as far as the Winnipiseogee, was first surveyed in 1652. The first settlers of Massachusetts supposed that the Connecticut, in one part of its course, ran northwest, “so near the great lake as the Indians do pass their canoes into it over land.” From which lake and the “hideous swamps” about it, as they supposed, came all the beaver that was traded between Virginia and Canada,—and the Potomac was thought to come out of or from very near it. Afterward the Connecticut came so near the course of the Merrimack that, with a little pains, they expected to divert the current of the trade into the latter river, and its profits from their Dutch neighbors into their own pockets.
