In the principal cities I found all the Daguerreans quite equal to the best in New York, and all doing good business, and I gave lessons in colouring to most of them. In Newark I met Messrs. Benjamin and Polson; in Philadelphia, Marcus Root and Dr. Bushnell. I encountered a great many _doctors_ and _professors_ in the business in America. In Baltimore, Maryland--then a slave State--many of the Daguerreans owned slaves. In Washington D.C., I renewed my acquaintance with Mr. George Adams, one of the best Daguerreans in the City; and while visiting him a very curious thing occurred. One of the representatives of the South came in to have his portrait taken, and the first thing he did was to lay a revolver and a bowie knife on the table beside him. He had just come from the House of Representatives. His excuse for such a proceeding was that he had bought some slaves at the market at Alexandria, and was going to take them home that night. He was a very tall man, and when he stood up against the background his head was above it. As he wanted to be taken standing, this put Mr. Adams into a dilemma, and he asked what he should do. I thought the only thing that could be done was to move the background up and down during exposure, which we did, and so obviated the appearance of a line crossing the head. While staying in Washington I attended one of the levées at the White House, and was introduced to President Pearce. There was no fuss or difficulty in gaining admission. I had only to present my card at the door, and the City Marshall at once led me into the room where the President, surrounded by some of his Cabinet, was waiting to receive, and I was introduced. After a cordial shake of his hand, I passed on to another saloon where there was music and promenading in mixed costumes, for most of the men were dressed as they liked, and some of the ladies wore bonnets. It was the weekly _sans cérémonie_ reception. Finding many of the people of Washington very agreeable and hospitable, I stayed there a considerable time. When I started on the southern journey I did intend to go on to New Orleans, but I stayed so long in Philadelphia and Washington the summer was too far advanced, and as a rather severe outbreak of yellow fever had occurred, I returned to New York and took a journey northward, visiting Niagara Falls, and going on to Canada. I sailed up the Hudson River, stopping at Albany and Troy. At the latter place I met an Englishman, named Irvine, a Daguerrean who treated me hospitably, and for whom I coloured several Daguerreotypes. He wanted me to stay with him, but that I declined. Thence I proceeded to Rochester, and there found that one of my New York pupils had been before me, representing himself as Werge the colourist, for when I introduced myself to the principal Daguerrean he told me that Werge--a very different man--had been there two or three weeks ago. I discovered who the fellow was, and that he had practised a piece of Yankee smartness
