Thoreau retired to Walden for study and contemplation, and because, as he said, he had a little private business with himself. He found that by working about six weeks in the year he could meet all his living expenses, and then have all his winter and most of his summers free and clear for study. He found that to maintain one's self on this earth is not a hardship, but a pastime, if one will live simply and wisely. He said, "It is not necessary that a man should earn his living by the sweat of his brow unless he sweats easier than I do." Was not his experiment worth while?
"Walden" is a wonderful and delightful piece of brag, but it is much more than that. It is literature; it is a Gospel of the Wild. It made a small Massachusetts pond famous, and the Mecca of many devout pilgrims.
Lowell says that Thoreau had no humor, but there are many pages in "Walden" that are steeped in a quiet but most delicious humor. His humor brings that inward smile which is the badge of art's felicity. His "Bean-Field" is full of it. I venture to say that never before had a hermit so much fun with a field of white beans.
Both by training and by temperament Lowell was disqualified from entering into Thoreau's character and aims. Lowell's passion for books and academic accomplishments was as strong as was Thoreau's passion for the wild and for the religion of Nature. When Lowell went to Nature for a theme, as in his "Good Word for Winter," his "My Garden Acquaintance," and the "Moosehead Journal," his use of it was mainly to unlock the treasures of his literary and scholarly attainments; he bedecked and be jeweled Nature with gems from all the literatures of the world. In the "Journal" we get more of the flavor of libraries than of the Maine woods and waters. No reader of Lowell can doubt that he was a nature-lover, nor can he doubt that he loved books and libraries more. In all his nature writings the poverty of the substance and the wealth of the treatment are striking. The final truth about Lowell's contributions is that his mind was essentially a prose mind, even when he writes poetry. Emerson said justly that his tone was always that of prose. What is his "Cathedral" but versified prose? Like so many cultivated men, he showed a talent for poetry, but not genius; as, on the other hand, one may say of Emerson that he showed more genius for poetry than talent, his inspiration surpassed his technical skill.
One is not surprised when he finds that John Brown was one of Thoreau's heroes; he was a sort of John Brown himself in another sphere; but one is surprised when one finds him so heartily approving of Walt Whitman and traveling to Brooklyn to look upon him and hear his voice. He recognized at once the tremendous significance of Whitman and the power of his poetry. He called him the greatest democrat which the world had yet seen. With all his asceticism and his idealism, he was not troubled at all with those things in Whitman that are a stumbling-block to so many persons. Evidently his long intercourse with Nature had prepared him for the primitive and elemental character of Whitman's work. No doubt also his familiarity with the great poems and sacred books of the East helped him. At any rate, in this respect, his endorsement of Whitman adds greatly to our conception of the mental and spiritual stature of Thoreau.
I can hold my criticism in the back of my head while I say with my forehead that all our other nature writers seem tame and insipid beside Thoreau. He was so much more than a mere student and observer of nature; and it is this surplusage which gives the extra weight and value to his nature writing. He was a critic of life, he was a literary force that made for plain living and high thinking. His nature lore was an aside; he gathered it as the meditative saunterer gathers a leaf, or a flower, or a shell on the beach, while he ponders on higher things. He had other business with the gods of the woods than taking an inventory of their wares. He was a dreamer, an idealist, a fervid ethical teacher, seeking inspiration in the fields and woods. The hound, the turtle-dove, and the bay horse which he said he had lost, and for whose trail he was constantly seeking, typified his interest in wild nature. The natural history in his books is quite secondary. The natural or supernatural history of his own thought absorbed him more than the exact facts about the wild life around him. He brings us a gospel more than he brings us a history. His science is only the handmaid of his ethics; his wood-lore is the foil of his moral and intellectual teachings. His observations are frequently at fault, or wholly wide of the mark; but the flower or specimen that he brings you always "comes laden with a thought." There is a tang and a pungency to nearly everything he published; the personal quality which flavors it is like the formic acid which the bee infuses into the nectar he gets from the flower, and which makes it honey.
I feel that some such statement about Thoreau should precede or go along with any criticism of him as a writer or as an observer. He was, first and last, a moral force speaking in the terms of the literary naturalist.
Thoreau's prayer in one of his poems—that he might greatly disappoint his friends—seems to have been answered. While his acquaintances went into trade or the professions, he cast about to see what he could do to earn his living and still be true to the call of his genius. In his Journal of 1851 he says: "While formerly I was looking about to see what I could do for a living, some sad experiences in conforming to the wishes of friends being fresh in my mind to tax my ingenuity, I thought often and seriously of picking huckleberries; that surely I could do, and its small profits might suffice, so little capital is required, so little distraction from my wonted thoughts." He could range the hills in summer and still look after the flocks of King Admetus. He also dreamed that he might gather the wild herbs and carry evergreens to such villagers as loved to be reminded of the woods. But he soon learned that trade cursed everything, and that "though you trade in messages from heaven, the whole curse of trade attaches to the business." The nearest his conscience would allow him to approach any kind of trade was to offer himself to his townsmen as a land-surveyor. This would take him to the places where he liked to be; he could still walk in the fields and woods and swamps and earn his living thereby. The chain and compass became him well, quite as well as his bean-field at Walden, and the little money they brought him was not entirely sordid.
In one of his happy moods in "Walden" he sets down in a half-facetious, half-mystical, but wholly delightful way, his various avocations, such as his self-appointment as inspector of snow-storms and rain-storms, and surveyor of forest paths and all across-lot routes, and herdsman of the wild stock of the town. He is never more enjoyable than in such passages. His account of going into business at Walden Pond is in the same happy vein. As his fellow citizens were slow in offering him any opening in which he could earn a living, he turned to the woods, where he was better known, and determined to go into business at once without waiting to acquire the usual capital. He expected to open trade with the Celestial Empire, and Walden was just the place to start the venture. He thought his strict business habits acquired through years of keeping tab on wild Nature's doings, his winter days spent outside the town, trying to hear what was in the wind, and his early spring mornings before his neighbors were astir to hear the croak of the first frog, all the training necessary to ensure success in business with the Celestial Empire. He admits, it is true, that he never assisted the sun materially in his rising, but doubted not that it was of the last importance only to be present at it. All such fooling as this is truly delightful. When he goes about his sylvan business with his tongue in his cheek and a quizzical, good-humored look upon his face in this way, and advertises the hound, the bay horse, and the turtle-dove he lost so long ago, he is the true Thoreau, and we take him to our hearts.
