I was sitting, one night, in the corridor of this, with the exception of its drinking "exchange," really good, well managed hotel, looking over the balustrade, at the in-coming and out-going throng, counting the numbers that went rum-ward as three to one, to those who went up the solid stone steps, already deeply worn by the constant dropping of feet, and trying to read the varied countenances of the ever-changing, varying scene before me. It is a useful study, to study our own kind; it is a good place, in the corridor of a great hotel, to practice. Every now and then, a face beamed out from the mass which made me sensible that it was not new, but whether an old acquaintance, or one seen before in some other crowd, I could not tell. Once only I was sure that the face which riveted my attention was that of one I had called friend, yet, for my life, I could not tell when or where. It was one of those faces which we never forget. It was one which a child would approach with confidence, to ask for a favor. It was one, which a stranger in his walk through the city, would pick out among a hundred, to ask for a direction to a particular street. Ten chances to one, he would not be satisfied to give that stranger a direction in words, but would turn round, and go a little out of the way to show the inquirer the best route, or stand upon the side-walk until one of the right line of stages came up so as to be sure that he went right. There are a few such faces, which go far to redeem the mass from the charge of coldness or selfishness, which does seem to be the distinguishing mark of the majority. I followed this one up the steps, and as far as the vision extended, as he walked away to one of the parlors. He was an elderly man, silvering with age, neatly, but plainly dressed, and I could not help feeling that he looked in everything about him, as though it would rejoice his very soul to have a chance to do a good action. I was not mistaken. You will not be if you read on. I could not sit still after he had passed up. I went into a long train of thought upon the mental question, the one absorbing question, "Who is he?" The argument grew intensely painful, and I became so much absorbed in it, that I almost forgot for a moment where I was, until I was brought back to consciousness by a little voice in my ear, of, "Please to buy these, sir." I almost said, no, without deigning to look up at the quasi beggar, as the frequency of the question, in all public places, is such that it is somewhat annoying. But there was a something in the tone of the voice that sent its magnetic power through me, and put down that spirit which gives the cold shoulder to the poor, and bids them "call again to-morrow."
