A peripatetic philosopher, and out-of-doors for the best part of his days and nights, he had manifold weather and seasons in him; the manners of an animal of probity and virtue unstained. Of all our moralists, he seemed the wholesomest, the busiest, and the best republican citizen in the world; always at home minding his own affairs. A little over-confident by genius, and stiffly individual, dropping society clean out of his theories, while standing friendly in his strict sense of friendship, there was in him an integrity and love of justice that made possible and actual the virtues of Sparta and the Stoics,--all the more welcome in his time of shuffling and pusillanimity. Plutarch would have made him immortal in his pages had he lived before his day. Nor have we any so modern withal, so entirely his own and ours: too purely so to be appreciated at once. A scholar by birthright, and an author, his fame had not, at his decease, travelled far from the banks of the rivers he described in his books; but one hazards only the truth in affirming of his prose, that in substance and pith, it surpasses that of any naturalist of his time; and he is sure of large reading in the future. There are fairer fishes in his pages than any swimming in our streams; some sleep of his on the banks of the Merrimack by moonlight that Egypt never rivalled; a morning of which Memnon might have envied the music, and a greyhound he once had, meant for Adonis; frogs, better than any of Aristophanes; apples wilder than Adam's. His senses seemed double, giving him access to secrets not easily read by others; in sagacity resembling that of the beaver, the bee, the dog, the deer; an instinct for seeing and judging, as by some other, or seventh sense; dealing with objects as if they were shooting forth from his mind mythologically, thus completing the world all round to his senses; a creation of his at the moment. I am sure he knew the animals one by one, as most else knowable in his town; the plants, the geography, as Adam did in his Paradise, if, indeed, he were not that ancestor himself. His works are pieces of exquisite sense, celebrations of Nature's virginity exemplified by rare learning, delicate art, replete with observations as accurate as original; contributions of the unique to the natural history of his country, and without which it were incomplete. Seldom has a head circumscribed so much of the sense and core of Cosmos as this footed intelligence.
