Only Thoreau's constant and unquenchable thirst for intellectual activity, and to supply material for that all-devouring Journal, can, to me, account for his main occupation during the greater part of the last two years of his life, which consisted in traversing the woods and measuring the trees and stumps and counting their rings. Apparently not a stump escaped him—pine, oak, birch, chestnut, maple, old or new, in the pasture or in the woods; he must take its measure and know its age. He must get the girth of every tree he passed and some hint of all the local conditions that had influenced its growth. Over two hundred pages of his Journal are taken up with barren details of this kind. He cross-questions the stumps and trees as if searching for the clue to some important problem, but no such problem is disclosed. He ends where he begins. His vast mass of facts and figures was incapable of being generalized or systematized. His elaborate tables of figures, so carefully arranged, absolutely accurate, no doubt, are void of interest, because no valuable inferences can be drawn from them.

"I have measured in all eight pitch pine stumps at the Tommy Wheeler hollow, sawed off within a foot of the ground. I measured the longest diameter and then at right angles with that, and took the average, and then selected the side of the stump on which the radius was of average length, and counted the number of rings in each inch, beginning at the center, thus:" And then follows a table of figures filling a page. "Of those eight, average growth about one seventh of an inch per year. Calling the smallest number of rings in an inch in each tree one, the comparative slowness of growth of the inches is thus expressed." Then follows another carefully prepared table of figures. Before one is done with these pages one fairly suspects the writer is mad, the results are so useless, and so utterly fail to add to our knowledge of the woods. Would counting the leaves and branches in the forest, and making a pattern of each, and tabulating the whole mass of figures be any addition to our knowledge? I attribute the whole procedure, as I have said, to his uncontrollable intellectual activity, and the imaginary demands of this Journal, which continued to the end of his life. The very last pages of his Journal, a year previous to his death, are filled with minute accounts of the ordinary behavior of kittens, not one item novel or unusual, or throwing any light on the kitten. But it kept his mind busy, and added a page or two to the Journal.

In his winter walks he usually carried a four-foot stick, marked in inches, and would measure the depth of the snow over large areas, every tenth step, and then construct pages of elaborate tables showing the variations according to locality, and then work out the average—an abnormal craving for exact but useless facts. Thirty-four measurements on Walden disclosed the important fact that the snow averaged five and one sixth inches deep. He analyzes a pensile nest which he found in the woods—doubtless one of the vireo's—and fills ten pages with a minute description of the different materials which it contained. Then he analyzes a yellow-bird's nest, filling two pages. That Journal shall not go hungry, even if there is nothing to give it but the dry material of a bird's nest.

The craving for literary expression in Thoreau was strong and constant, but, as he confesses, he could not always select a theme. "I am prepared not so much for contemplation as for forceful expression." No matter what the occasion, "forceful expression" was the aim. No meditation, or thinking, but sallies of the mind. All his paradoxes and false analogies and inconsistencies come from this craving for a forceful expression. He apparently brought to bear all the skill he possessed of this kind on all occasions. One must regard him, not as a great thinker, nor as a disinterested seeker after the truth, but as a master in the art of vigorous and picturesque expression. To startle, to wake up, to communicate to his reader a little wholesome shock, is his aim. Not the novelty and freshness of his subject-matter concerns him but the novelty and unhackneyed character of his literary style. That throughout the years a man should keep up the habit of walking, by night as well as by day, and bring such constant intellectual pressure to bear upon everything he saw, or heard, or felt, is remarkable. No evidence of relaxation, or of abandonment to the mere pleasure of the light and air and of green things growing, or of sauntering without thoughts of his Journal. He is as keyed up and strenuous in his commerce with the Celestial Empire as any tradesman in world goods that ever amassed a fortune. He sometimes wrote as he walked, and expanded and elaborated the same as in his study. On one occasion he dropped his pencil and could not find it, but he managed to complete the record. One night on his way to Conantum he speculates for nearly ten printed pages on the secret of being able to state a fact simply and adequately, or of making one's self the free organ of truth—a subtle and ingenious discussion with the habitual craving for forceful expression. In vain I try to put myself in the place of a man who goes forth into wild nature with malice prepense to give free swing to his passion for forcible expression. I suppose all nature-writers go forth on their walks or strolls to the fields and woods with minds open to all of Nature's genial influences and significant facts and incidents, but rarely, I think, with the strenuousness of Thoreau—grinding the grist as they go along.

Thoreau compares himself to the bee that goes forth in quest of honey for the hive: "How to extract honey from the flower of the world. That is my everyday business. I am as busy as the bee about it. I ramble over all fields on that errand and am never so happy as when I feel myself heavy with honey and wax." To get material for his Journal was as much his business as it was the bee's to get honey for his comb. He apparently did not know that the bee does not get honey nor wax directly from the flowers, but only nectar, or sweet water. The bee, as I have often said, makes the honey and the wax after she gets home to the swarm. She puts the nectar through a process of her own, adds a drop of her own secretion to it, namely, formic acid, the water evaporates, and lo! the tang and pungency of honey!

There can be little doubt that in his practical daily life we may credit Thoreau with the friendliness and neighborliness that his friend Dr. Edward W. Emerson claims for him. In a recent letter to me, Dr. Emerson writes: "He carried the old New England undemonstrativeness very far. He was also, I believe, really shy, prospered only in monologue, except in a walk in the woods with one companion, and his difficulties increased to impossibility in a room full of people." Dr. Emerson admits that Thoreau is himself to blame for giving his readers the impression that he held his kind in contempt, but says that in reality he had neighborliness, was dutiful to parents and sisters, showed courtesy to women and children and an open, friendly side to many a simple, uncultivated townsman.

This practical helpfulness and friendliness in Thoreau's case seems to go along with the secret contempt he felt and expressed in his Journal toward his fellow townsmen. At one time he was chosen among the selectmen to perambulate the town lines—an old annual custom. One day they perambulated the Lincoln line, the next day the Bedford line, the next day the Carlisle line, and so on, and kept on their rounds for a week. Thoreau felt soiled and humiliated. "A fatal coarseness is the result of mixing in the trivial affairs of men. Though I have been associating even with the select men of this and adjoining towns, I feel inexpressibly begrimed." How fragile his self-respect was! Yet he had friends among the surrounding farmers, whose society and conversation he greatly valued.

That Thoreau gave the impression of being what country folk call a crusty person—curt and forbidding in manner—seems pretty well established. His friend Alcott says he was deficient in the human sentiments. Emerson, who, on the whole, loved and admired him, says: "Thoreau sometimes appears only as a gendarme, good to knock down a cockney with, but without that power to cheer and establish which makes the value of a friend." Again he says: "If I knew only Thoreau, I should think coöperation of good men impossible. Must we always talk for victory, and never once for truth, for comfort, and joy? Centrality he has, and penetration, strong understanding, and the higher gifts,—the insight of the real, or from the real, and the moral rectitude that belongs to it; but all this and all his resources of wit and invention are lost to me, in every experiment, year after year, that I make, to hold intercourse with his mind. Always some weary captious paradox to fight you with, and the time and temper wasted." "It is curious," he again says, "that Thoreau goes to a house to say with little preface what he has just read or observed, delivers it in a lump, is quite inattentive to any comment or thought which any of the company offer on the matter, nay, is merely interrupted by it, and when he has finished his report departs with precipitation."
