Ordinarily the sale of the stocks offered, proceeds in a monotonous, humdrum manner, but when "Erie," or "Pacific Mail," or any other favorite stock is called, each man springs to his feet. Bids come fast and furious, hands, arms, hats, and canes are waved frantically overhead to attract the attention of the presiding officer. The most intense excitement prevails throughout the room, and the shouts and cries are deafening. Sales are made with the utmost rapidity, and the excitement is kept up at the highest point as long as any thing of interest is offered. If a sale is contested, the president names the purchaser, and his decision is final, unless revoked by an instantaneous vote of the Board. THE OPEN BOARD. The Open Board of Stock Brokers meet in the second story of a handsome brown stone building adjoining the Stock Exchange. Their sessions are from ten until one. The business of the Board is similar to that of the Stock Exchange, and is dispatched with as much precision, quickness, and clamor. THE GOLD ROOM. Descending from Broad street to the basement of the building used by the "Open Board," we find ourselves in a long, dimly lighted passage- way, which leads us into a small courtyard. As we emerge into this yard, we hear a confused hum above our heads, which grows louder as we ascend the steep stairway before us. Passing through a narrow, dirty entry, we open a side door, and our ears fairly ache with the yells and shrieks with which we are startled. For a moment we think we are about to enter a company of lunatics, but we pass on reassured, and the next instant stand in the Gold Room. This is a handsome apartment, in the style of an amphitheatre, with a fountain in the centre. A gallery runs around the upper part, and several telegraph offices are connected with the room. There are but few benches. The members of the Board are always too much excited to sit, and seats are only in the way. Though the main entrance is on Broadway, the Gold Room really fronts on New street. During the sessions of the Board, it is filled with an excited, yelling crowd, rushing about wildly, and, to a stranger, without any apparent aim. The men stamp, yell, shake their arms, heads, and bodies violently, and almost trample each other to death in the violent struggle. Men, who in private life excite the admiration of their friends and acquaintances by the repose and dignity of their manner, here lose their self- possession entirely, and are more like maniacs than sensible beings. Few members of either the Stock or Gold Boards operate for themselves. They generally buy and sell for outside parties, from whom they require a guarantee at the outset, and charge a fair commission on the sale for their services. Members have confidence in each other, for they know that no one can afford to be dishonest. Expulsion and financial ruin and disgrace are the swift and inflexible punishments of bad faith.
