HELP QUICK! MONDAY. - It was, if I remember rightly, five o'clock when we were all signalled to be present at the Ferry Depot of the railroad...There was a babel of bewildered men, women, and children. The wretched little booking-office, and the baggage-room, which was not much larger, were crowded thick with emigrants, and were heavy and rank with the atmosphere of dripping clothes. Open carts full of bedding stood by the half-hour in the rain. The officials loaded each other with recriminations. A bearded, mildewed little man, whom I take to have been an emigrant agent, was all over the place, his mouth full of brimstone, blustering and interfering. It was plain that the whole system, if system there was, had utterly broken down under the strain of so many passengers.
