In 1835 commenced the geological survey of Connecticut, and I became Percival's companion in labor. To him was intrusted the geology proper, and to myself the mineralogy and its economical applications. During the first season, we prosecuted our investigations together, travelling in a one-horse wagon, which carried all our necessary implements, and visiting, before the campaign ended, every parish in the State. Great was the wonder our strange outfit and occupation excited in some rustic neighborhoods; and very often were we called upon to enlighten the popular mind with regard to our object and its uses. This was never a pleasant task to Percival. He did not relish long confabulations with a sovereign people somewhat ignorant of geology; and, moreover, his style of describing our business was so peculiar, that it rarely failed to transfer the curiosity to himself, and lead to tiresome delays. In New Milford, an inquisitive farmer requested us, in a somewhat ungracious manner, to give an account of ourselves. Percival replied, that we were acting under a commission from the Governor to ascertain the useful minerals of the State; whereupon our utilitarian friend immediately demanded to be informed how the citizens at large, including himself, were to be benefited by the undertaking,--putting question on question in a fashion which was most pertinacious and almost impertinent. Percival became impatient, and tried to hurry away. "I demand the information," exclaimed the New Milfordite; "I demand it as my right. You are only servants of the people; and you are paid, in part, at least, out of my pocket." "I'll tell you what we'll do," said Percival; "we can't stop, but we'll refund. Your portion of the geological tax,--let me see,--it must be about two cents. We prefer handing you this to encountering a further delay." Our agricultural friend and master did not take the money, although he did the hint,--and in sulky silence withdrew from our company. Driving through the town of Warren, we stopped a farmer to inquire the way to certain places in the vicinity. He gave us the information sought, staring at us meanwhile with a benevolently inquisitive expression, and, at last, volunteering the remark, that, if we wanted a job, we had better stop at the factory in the hollow. We thanked him for his goodness, and thought, perhaps, of Sedgewick geologizing by the road-side, and getting a charitable half-crown flung at him by a noble lady who was on her way to dine in his company at the house of a mutual acquaintance.
