Mr. Burroughs ascribes to Emerson, who stimulated his religious nature, his improved literary expression; while Whitman was to him a great humanizing power, and Matthew Arnold taught him clear thinking and clean writing. He had passed through these different influences by the time he was twenty-one or twenty-two; had taught for a while; and from 1863 to 1873 was vault-keeper and afterwards chief of the organization division of the Bureau of National Banks, in the Treasury Department. For several years afterward he was a special national bank examiner.
The literary quality of his writings from the first captivates the reader. He has the interpretive power which makes us see what he sees and invites us to share his enjoyment in his strange adventures. The stories of the wary trout and the pastoral bee, the ways of sylvan folk, their quarrels and their love-making, are so many character sketches on paper, showing a most intimate acquaintance with nature.
He is a born naturalist. He tells us that from childhood he was familiar with the homely facts of the barn, the cattle and the horses, the sugar-making and the work of the corn-field, the hay-field, the threshing, the planting, the burning of fallows. He "loved nature in those material examples and subtle expressions, with a love passing all the books in the world." But he also loved and knew books, and this other love gives to his works their literary charm.
His account of a bird, a flower, or an open-air incident, however painstaking and minute the record, teems with literary memories. The sight of the Scotch hills recalls Shakespeare's line,
"The tufty mountains where lie the nibbling sheep."
The plane-tree vocal with birds' voices recalls Tennyson,—"The pillared dusk of sounding sycamores"; he hears the English chaffinch, and remembers with keen delight that Drayton calls it "the throstle with sharp thrills," and Ben Jonson "the lusty throstle." After much wondering, he finds out why Shakespeare wrote
"The murmuring surge
That on the unnumbered idle pebbles chafes,"
his own experience being that sea-shores are sandy; but the pebbled cliffs of Folkestone, with not a grain of sand on the chalk foundation, justified the poet.
This lover of nature loves not only the beautiful things he sees, but he loves what they suggest, what they remind him of, what they bid him aspire to. Like Wordsworth, he "looks on the hills with tenderness, and makes deep friendship with the streams and groves." He notes what he divines by observation. And what an observer he is! He discovers that the bobolink goes south in the night. He scraped an acquaintance with a yellow rumpled warbler who, taking the reflection of the clouds and blue sky in a pond for a short cut to the tropics, tried to cross it; with the result of his clinging for a day and night to a twig that hung down in the water.
Burroughs has found that whatever bait you use in a trout stream,—grasshopper, grub, or fly,—there is one thing you must always put on your hook; namely, your heart. It is a morsel they love above everything else. He tells us that man has sharper eyes than a dog, a fox, or any of the wild creatures except the birds, but not so sharp an ear or a nose; he says that a certain quality of youth is indispensable in the angler, a certain unworldliness and readiness to invest in an enterprise that does not pay in current coin. He says that nature loves to enter a door another hand has opened: a mountain view never looks better than when one has been warmed up by the capture of a big trout. Like certain wary game, she is best taken by seeming to pass her by, intent on other matters. What he does not find out for himself, people tell him. From a hedge-cutter he learns that some of the birds take an earth-bath and some a water-bath, while a few take both; a farmer boy confided to him that the reason we never see any small turtles is because for two or three years the young turtles bury themselves in the ground and keep hidden from observation. From a Maine farmer he heard that both male and female hawks take part in incubation. A barefooted New Jersey boy told him that "lampers" die as soon as they have built their nests and laid their eggs. How apt he is in similes! The pastoral fields of Scotland are "stall-fed," and the hill-sides "wrinkled and dimpled, like the forms of fatted sheep."
