On the following morning, at the hour which my landlady told me would be most convenient, I went to call upon the professor, whom I found in his study; though how he contrived to study at all, I cannot make out; for he was in a state of continual movement—the most excitable German I ever saw. During the greater part of the time he was talking to me, he was taking down one book and putting up another, turning over papers upon the table, dipping a pen in the ink and wiping it again, with other operations to carry off his superfluous activity. He must have been quiet at some time; for he certainly was a very learned man; but I never could discover when it was. At length, after having asked a great number of questions, he said—“I have got one pupil for you, to make a beginning—Come, I’ll show her to you;” and leading me into another room, on the same floor, he presented me to a young lady, who sat there embroidering, as his daughter. “There,” he said, “teach her English, and any thing else you can. I have no time—she is a good girl, but slow.” The young lady looked up in his face with a calm, placid smile, saying, “If there were two such quick people as you in the house, my father, they would always be running against each other.” “True,” replied the old man, “true, and philosophical. Nature loves contrasts as well as harmonies. Opposing forces counteract each other. You, my Louise, are my _vis inertiæ_. Without you I should get on too fast. But come, young gentleman—what is your name?” “Louis de Lacy,” I replied. “I like that, I like that,” answered the old man “The _De_, speaks blood and good political principles—but come—we will settle the terms in my own room, and will try to get you something more to do by and bye.” I found the good professor had as accurate a knowledge of making a bargain, as he had of Greek or Latin. He calculated the worth of my services to a pfennig, and, as I found afterward, if I had made the slightest opposition, would have beaten me down still lower; for he had a pleasure in such sort of triumphs. I let him arrange it all his own way, however, and left to his own generosity, he probably added a little to the sum which he had intended to give. It was agreed that I was to teach his daughter two hours during the day, and as soon as all this was settled, he pushed me by the shoulders toward the door, saying, “There, go, begin at once. You have three hours before dinner. I must go to my recitations.”
