As we lay awake long before daybreak, listening to the rippling of the river, and the rustling of the leaves, in suspense whether the wind blew up or down the stream, was favorable or unfavorable to our voyage, we already suspected that there was a change in the weather, from a freshness as of autumn in these sounds. The wind in the woods sounded like an incessant waterfall dashing and roaring amid rocks, and we even felt encouraged by the unusual activity of the elements. He who hears the rippling of rivers in these degenerate days will not utterly despair. That night was the turning point in the season. We had gone to bed in summer, and we awoke in autumn; for summer passes into autumn in some unimaginable point of time, like the turning of a leaf.
We found our boat in the dawn just as we had left it, and as if waiting for us, there on the shore, in autumn, all cool and dripping with dew, and our tracks still fresh in the wet sand around it, the fairies all gone or concealed. Before five o'clock we pushed it into the fog, and, leaping in, at one shove were out of sight of the shores, and began to sweep downward with the rushing river, keeping a sharp lookout for rocks. We could see only the yellow gurgling water, and a solid bank of fog on every side, forming a small yard around us. We soon passed the mouth of the Souhegan, and the village of Merrimack, and as the mist gradually rolled away, and we were relieved from the trouble of watching for rocks, we saw by the flitting clouds, by the first russet tinge on the hills, by the rushing river, the cottages on shore, and the shore itself, so coolly fresh and shining with dew, and later in the day, by the hue of the grape-vine, the goldfinch on the willow, the flickers flying in flocks, and when we passed near enough to the shore, we fancied, by the faces of men, that the Fall had commenced. The cottages looked more snug and comfortable, and their inhabitants were seen only for a moment, and then went quietly in and shut the door, retreating inward to the haunts of summer.
"And now the cold autumnal dews are seen
To cobweb ev'ry green;
And by the low-shorn rowens doth appear
The fast-declining year."
We heard the sigh of the first autumnal wind, and even the water had acquired a grayer hue. The sumach, grape, and maple were already changed, and the milkweed had turned to a deep rich yellow. In all woods the leaves were fast ripening for their fall; for their full veins and lively gloss mark the ripe leaf, and not the sered one of the poets; and we knew that the maples, stripped of their leaves among the earliest, would soon stand like a wreath of smoke along the edge of the meadow. Already the cattle were heard to low wildly in the pastures and along the highways, restlessly running to and fro, as if in apprehension of the withering of the grass and of the approach of winter. Our thoughts, too, began to rustle.
