Now it is true that I could have learned without a teacher, but it would have been risky for me, because of my natural clumsiness. The self-taught man seldom knows anything accurately, and he does not know a tenth as much as he could have known if he had worked under teachers; and, besides, he brags, and is the means of fooling other thoughtless people into going and doing as he himself has done. There are those who imagine that the unlucky accidents of life—life’s “experiences”—are in some way useful to us. I wish I could find out how. I never knew one of them to happen twice. They always change off and swap around and catch you on your inexperienced side. If personal experience can be worth anything as an education, it wouldn’t seem likely that you could trip Methuselah; and yet if that old person could come back here it is more than likely that one of the first things he would do would be to take hold of one of these electric wires and tie himself all up in a knot. Now the surer thing and the wiser thing would be for him to ask somebody whether it was a good thing to take hold of. But that would not suit him; he would be one of the self-taught kind that go by experience; he would want to examine for himself. And he would find, for his instruction, that the coiled patriarch shuns the electric wire; and it would be useful to him, too, and would leave his education in quite a complete and rounded-out condition, till he should come again, some day, and go to bouncing a dynamite-can around to find out what was in it. But we wander from the point. However, get a teacher; it saves much time and Pond’s Extract. Before taking final leave of me, my instructor inquired concerning my physical strength, and I was able to inform him that I hadn’t any. He said that that was a defect which would make up-hill wheeling pretty difficult for me at first; but he also said the bicycle would soon remove it. The contrast between his muscles and mine was quite marked. He wanted to test mine, so I offered my biceps—which was my best. It almost made him smile. He said, “It is pulpy, and soft, and yielding, and rounded; it evades pressure, and glides from under the fingers; in the dark a body might think it was an oyster in a rag.” Perhaps this made me look grieved, for he added, briskly: “Oh, that’s all right, you needn’t worry about that; in a little while you can’t tell it from a petrified kidney. Just go right along with your practice; you’re all right.” Then he left me, and I started out alone to seek adventures. You don’t really have to seek them—that is nothing but a phrase—they come to you. I chose a reposeful Sabbath-day sort of a back street which was about thirty yards wide between the curbstones. I knew it was not wide enough; still, I thought that by keeping strict watch and wasting no space unnecessarily I could crowd through.
