So, too, one is thankful to come upon a really amusing dissertation about the tying of shoe-strings, or rather about their too easy untying; a matter with which, it appears, Thoreau had for years experienced "a great deal of trouble." His walking companion (Channing, presumably) and himself had often compared notes about it, concluding after experiments that the duration of a shoe-tie might be made to serve as a reasonably accurate unit of measure, as accurate, say, as a stadium or a league. Channing, indeed, would sometimes go without shoe-strings, rather than be plagued so incessantly by their dissolute behavior. Finally Thoreau, being then thirty-six years old, and always exceptionally clever with his hands, set his wits seriously at work upon knots, and by a stroke of good fortune (or a stroke of genius) hit upon one which answered his end; only to be told, on communicating his discovery to a third party, that he had all his life been tying "granny knots," never having learned, at school or elsewhere, the secret of a square one! It might be well, he concludes, if all children were "taught the accomplishment." Verily, as Hosea Biglow did not say, they didn't know everything down in Concord. More refreshing still are entries describing hours of serene communion with nature, hours in which, as in an instance already cited, the Spirit of the Lord blessed him, and he forgot even to be good. These entries, likewise, are less numerous than could be wished, though perhaps as frequent as could fairly be expected; since ecstasies, like feasts, must in the nature of things be somewhat broadly spaced; and it is interesting, not to say surprising, to see how frankly he looks upon them afterward as subjects on which to try his pen. In these "seasons when our genius reigns we may be powerless for expression," he remarks; but in calmer hours, when talent is again active, "the memory of those rarer moods comes to color our picture, and is the permanent paint-pot, as it were, into which we dip our brush." But, in truth, the whole journal, some volumes of which are carefully indexed in his own hand, is quite undisguisedly a collection of thoughts, feelings, and observations, out of which copy is to be extracted. In it, he says, "I wish to set down such choice experiences that my own writings may inspire me, and at last I may make wholes of parts.... Each thought that is welcomed and recorded is a nest-egg by the side of which more will be laid." A born writer, he is "greedy of occasions to express" himself. He counts it "wise to write on many subjects, that so he may find the right and inspiring one." "There are innumerable avenues to a perception of the truth," he tells himself. "Improve the suggestion of each object, however humble, however slight and transient the provocation. What else is there to be improved?"
