If a doubtful check is presented, if paper to be negotiated is not exactly clear, while the party offering the paper or check is entertained by some member of the bank, the telegraph is making minute inquiries about his financial standing. Before the conference closes, the bank knows the exact facts of the case." V. CURB-STONE BROKERS. The members of the Stock and Gold Exchange, as has been stated, are men of character. Their transactions are governed by certain fixed rules, and they are required, on pain of expulsion from the Exchange, to observe the strictest good faith in their dealings with each other and with their customers. If the operations of the street were entirely confined to them, business in Wall street might be regarded as in safe hands. But there is another class, even more numerous and quite as well skilled in the ways of the street, who transact a vast part of its business. They are not members of the Exchange, and in former times used to assemble around its doors in Broad and New streets, and carry on their operations on the sidewalk. Hence their designation, "Curb-stone brokers." They no longer assemble on the pavement, for the Exchange has thrown open to them its Long Room. Any one who can pay $50 a year for a ticket of admission, and who has brains and nerve enough to enter upon the struggle, can sell or buy in the Long Room. This is better than standing in the street, exposed to the weather, and moreover gives a certain respectability to the "operator," although he may carry his sole capital in his head, and his office in his breeches-pocket. No rules or regulations apply to the Long Room. The honest man and the rogue mingle together here, and the broker must be sure of his man. Many of the members of the Exchange buy and sell here, either in person or through their representatives, and many good men who are unable to enter the Exchange conduct their business here. Others again prefer the freedom and the wider field of the Long Room. Still, there are many sharpers here, who would fleece a victim out of his last cent. The daily transactions of the Long Room are said to average about $70,000,000, or ten times the business done in the Regular Board. Fortune is much more uncertain here than in the room up stairs. Men buy and sell here with the recklessness of gamblers. The noise and excitement are almost as great as in the Gold Room. The absence of the fixed laws of the Regular Boards puts every one on his own resources, and men are compelled to use all their ingenuity, all their determination to guard against a surprise or unfair dealing. It is every one for himself here. A dozen or more small or new operators are ruined and swept away daily, and in times of great financial excitement the Long Room shakes the foundations of even some of the strongest houses in the street.
