first nail? I shall never repeat a conversation, but an idea often. I shall use the same types when I like, but not commonly the same stereotypes. A thought is often original, though you have uttered it a hundred times. It has come to you over a new route, by a new and express train of associations. Sometimes, but rarely, one may be caught making the same speech twice over, and yet be held blameless. Thus, a certain lecturer, after performing in an inland city, where dwells a Littératrice of note, was invited to meet her and others over the social teacup. She pleasantly referred to his many wanderings in his new occupation. “Yes,” he replied, “I am like the Huma, the bird that never lights, being always in the cars, as he is always on the wing.”—Years elapsed. The lecturer visited the same place once more for the same purpose. Another social cup after the lecture, and a second meeting with the distinguished lady. “You are constantly going from place to place,” she said.—“Yes,” he answered, “I am like the Huma,”—and finished the sentence as before. What horrors, when it flashed over him that he had made this fine speech, word for word, twice over! Yet it was not true, as the lady might perhaps have fairly inferred, that he had embellished his conversation with the Huma daily during that whole interval of years. On the contrary, he had never once thought of the odious fowl until the recurrence of precisely the same circumstances brought up precisely the same idea. He ought to have been proud of the accuracy of his mental adjustments. Given certain factors, and a sound brain should always evolve the same fixed product with the certainty of Babbage’s calculating machine. —What a satire, by the way, is that machine on the mere mathematician! A Frankenstein-monster, a thing without brains and without heart, too stupid to make a blunder; that turns out results like a corn-sheller, and never grows any wiser or better, though it grind a thousand bushels of them! I have an immense respect for a man of talents plus “the mathematics.” But the calculating power alone should seem to be the least human of qualities, and to have the smallest amount of reason in it; since a machine can be made to do the work of three or four calculators, and better than any one of them. Sometimes I have been troubled that I had not a deeper intuitive apprehension of the relations of numbers. But the triumph of the ciphering hand-organ has consoled me. I always fancy I can hear the wheels clicking in a calculator’s brain. The power of dealing with numbers is a kind of “detached lever” arrangement,
