temperature of distant atmospheres was graduated, and it was some attraction for us that the breeze it played with had been out of doors so long. Thus we sailed, not being able to fly, but as next best, making a long furrow in the fields of the Merrimack toward our home, with our wings spread, but never lifting our heel from the watery trench; gracefully plowing homeward with our brisk and willing team, wind and stream, pulling together, the former yet a wild steer, yoked to his more sedate fellow. It was very near flying, as when the duck rushes through the water with an impulse of her wings, throwing the spray about her, before she can rise. How we had stuck fast if drawn up but a few feet on the shore!
When we reached the great bend just above Middlesex, where the river runs east thirty-five miles to the sea, we at length lost the aid of this propitious wind, though we contrived to make one long and judicious tack carry us nearly to the locks of the canal. We were here locked through at noon by our old friend, the lover of the higher mathematics, who seemed glad to see us safe back again through so many locks; but we did not stop to consider any of his problems, though we could cheerfully have spent a whole autumn in this way another time, and never have asked what his religion was. It is so rare to meet with a man out-doors who cherishes a worthy thought in his mind, which is independent of the labor of his hands. Behind every man's busy-ness there should be a level of undisturbed serenity and industry, as within the reef encircling a coral isle there is always an expanse of still water, where the depositions are going on which will finally raise it above the surface.
