This occurrence put me on my guard, and made me very wary of buying articles at such auctions during my stay in New York, although the apparent beauty and cheapness of many of the articles I saw offered, especially of French manufacture, were sufficient to decoy the most wary, and I did not wonder at people being victimized at such places. Emigrants are the chief sufferers, I was told, by such transactions, from their want of caution, and ignorance of the arts of the accomplished deceivers who conduct them. Proceeding up Wall-street in the direction of Broadway, I reached that portion of it frequented by stock and real-estate brokers. Here crowds of gentlemanly-looking men, dressed mostly in black, and of busy mien, crowded the thoroughfare with scrip in hand. Each appeared intensely absorbed in business, and as I gazed on the assemblage, I could discover unmistakable symptoms of great excitement and mental anxiety, the proportion of rueful countenances being much greater than is usually seen in similar places of resort in England; a sudden depression in the market at the time might, however, account for much of this, although it is well known that brokers and speculators on the American continent engage in the pursuit with the avidity of professed gamblers. Hundreds of Negroes were hurrying to and fro through the streets, these were chiefly labourers, decently dressed, and employed either as draymen or porters. They looked happier than labourers in England; and, being bathed in a profuse perspiration from the heat of the weather, their faces shone almost like black satin or patent leather.
