There was still no doubt in his mind that the adventure was a mad one. It was all very well for Susy to remind him twenty times a day that they had pulled it off--and so why should he worry? Even in the light of her far-seeing cleverness, and of his own present bliss, he knew the future would not bear the examination of sober thought. And as he sat there in the summer moonlight, with her head on his knee, he tried to recapitulate the successive steps that had landed them on Streffy’s lake-front. On Lansing’s side, no doubt, it dated back to his leaving Harvard with the large resolve not to miss anything. There stood the evergreen Tree of Life, the Four Rivers flowing from its foot; and on every one of the four currents he meant to launch his little skiff. On two of them he had not gone very far, on the third he had nearly stuck in the mud; but the fourth had carried him to the very heart of wonder. It was the stream of his lively imagination, of his inexhaustible interest in every form of beauty and strangeness and folly. On this stream, sitting in the stout little craft of his poverty, his insignificance and his independence, he had made some notable voyages.... And so, when Susy Branch, whom he had sought out through a New York season as the prettiest and most amusing girl in sight, had surprised him with the contradictory revelation of her modern sense of expediency and her old-fashioned standard of good faith, he had felt an irresistible desire to put off on one more cruise into the unknown.
