Since he did not marry and incur responsibilities for others, he was free to choose his own manner of life. His regular habit was to reserve half of every day for walking in the woods; but for two years and two months he lived alone in the forest, in a small house that he himself built upon a piece of Emerson's property beside Walden Pond, about a mile south of Concord. Thoreau found that he could earn enough in six weeks to support himself in this simple way for the rest of the year. He thus acquired the leisure to write books that are each year read with increasing interest. The record of his life at Walden forms the basis for his best known work. A few people practice the return to nature for a short time, but Thoreau spent his available life with nature.

He was a pronounced individualist, carrying out Emerson's doctrine by becoming independent of others' opinions. What he thought right, he said or did. He disapproved, for example, of slavery, and consequently refused to pay his poll tax to a government that upheld slavery. When he was imprisoned because of non-payment, Emerson visited him and asked, "Why are you here, Henry?" Thoreau merely replied, "Why are you not here?"

His intense individualism made him angular, and his transcendental love of isolation caused him to declare that he had never found "the companion that was so companionable as solitude"; but he was, nevertheless, spicy, original, loyal to friends, a man of deep family affection, stoical in his ability to stand privations, and Puritanic in his conviction about the moral aim of life. His last illness, induced by exposure to cold, confined him for months away from the out of doors that he loved. In 1862, at the age of forty-five, he said, as he lay on his deathbed, "When I was a very little boy, I learned that I must die, and I set that down, so, of course, I am not disappointed now." He was buried not far from Emerson's lot in the famous Sleepy Hollow cemetery at Concord.

WORKS.—Only two of his books were published during his lifetime. These were A Week on the Concord and Merrimac Rivers (1849) and Walden (1854). The first of these, usually referred to as The Week, is the record of a week spent in a rowboat on the rivers mentioned in the title. The clearness and exactness of the descriptions are remarkable. Whenever he investigated nature, he took faithful notes so that when he came to write a more extended description or a book, he might have something more definite than vague memory impressions on which to rely. When he describes in The Week a mere patch of the river bank, this definiteness of observation is manifest:—

"The dead limbs of the willow were rounded and adorned by the climbing milkania, Milkania scandens, which filled every crevice in the leafy bank, contrasting agreeably with the gray bark of its supporter and the balls of the button-bush."

This book did not prove popular, and almost three fourths of the edition were left on his hands. This unfortunate venture caused him to say, "I have now a library of nearly nine hundred volumes, over seven hundred of which were written by myself."

Walden is the book by which Thoreau is best known. It is crisper, livelier, more concise and humorous, and less given to introspective philosophizing than The Week. Walden, New England's Utopia, is the record of Thoreau's experiment in endeavoring to live an ideal life in the forest. This book differs from most of its kind in presenting actual life, in not being mainly evolved from the inner consciousness on the basis of a very little experience. He thus states the reason why he withdrew to the forest:—

"I went to the woods because I wished to live deliberately, to front only the essential facts of life, and see if I could not learn what it had to teach, and not, when I came to die, discover that I had not lived. I did not wish to live what was not life, living is so dear."
