On board a steamer I once met an elderly man, with such a merry face that, if it was really an index of his mind, he must have been the happiest fellow in creation; and indeed he considered himself so, for I heard it from his own mouth. He was a Dane, the owner of a travelling theatre. He had all his company with him in a large box, for he was the proprietor of a puppet-show. His inborn cheerfulness, he said, had been tested by a member of the Polytechnic Institution, and the experiment had made him completely happy. I did not at first understand all this, but afterwards he explained the whole story to me; and here it is:—

"I was giving a representation," he said, "in the hall of the posting-house in the little town of Slagelse; there was a splendid audience, entirely juvenile excepting two respectable matrons. All at once, a person in black, of student-like appearance, entered the room, and sat down; he laughed aloud at the telling points, and applauded quite at the proper time. This was a very unusual spectator for me, and I felt anxious to know who he was. I heard that he was a member of the Polytechnic Institution in Copenhagen, who had been sent out to lecture to the people in the provinces. Punctually at eight o'clock my performance closed, for children must go early to bed, and a manager must also consult the convenience of the public.

"At nine o'clock the lecturer commenced his lecture and his experiments, and then I formed a part of his audience. It was wonderful both to hear and to see. The greater part of it was beyond my comprehension, but it led me to think that if we men can acquire so much, we must surely be intended to last longer than the little span which extends only to the time when we are hidden away under the earth. His experiments were quite miracles on a small scale, and yet the explanations flowed as naturally as water from his lips. At the time of Moses and the prophets, such a man would have been placed among the sages of the land; in the middle ages they would have burnt him at the stake.

"All night long I could not sleep; and the next evening when I gave another performance and the lecturer was present, I was in one of my best moods.

"I once heard of an actor, who, when he had to act the part of a lover, always thought of one particular lady in the audience; he only played for her, and forgot all the rest of the house, and now the Polytechnic lecturer was my she, my only auditor, for whom alone I played.

"When the performance was over, and the puppets removed behind the curtain, the Polytechnic lecturer invited me into his room to take a glass of wine. He talked of my comedies, and I of his science, and I believe we were both equally pleased. But I had the best of it, for there was much in what he did that he could not always explain to me. For instance, why a piece of iron which is rubbed on a cylinder, should become magnetic. How does this happen? The magnetic sparks come to it,—but how? It is the same with people in the world; they are rubbed about on this spherical globe till the electric spark comes upon them, and then we have a Napoleon, or a Luther, or some one of the kind.

"'The whole world is but a series of miracles,' said the lecturer, 'but we are so accustomed to them that we call them everyday matters.' And he went on explaining things to me till my skull seemed lifted from my brain, and I declared that were I not such an old fellow, I would at once become a member of the Polytechnic Institution, that I might learn to look at the bright side of everything, although I was one of the happiest of men.

"'One of the happiest!' said the lecturer, as if the idea pleased him; 'are you really happy?'

"'Yes,' I replied; 'for I am welcomed in every town, when I arrive with my company; but I certainly have one wish which sometimes weighs upon my cheerful temper like a mountain of lead. I should like to become the manager of a real theatre, and the director of a real troupe of men and women.'

"'I understand,' he said; 'you would like to have life breathed into your puppets, so that they might be living actors, and you their director. And would you then be quite happy?'

"I said I believed so. But he did not; and we talked it over in all manner of ways, yet could not agree on the s............
