In former times brokers were subjected to great expense in keeping a host of runners and messengers to bring them news of the transactions at the Exchanges. The introduction of the Stock Telegraph has made a great and beneficial change in this respect. In every broker's office, and in the principal hotels and restaurants of the city, there is an automatic recording instrument connected by telegraphic wires with an instrument in the Stock and Gold Exchanges. The operator in these exchanges indicates the quotations of stocks and gold on his own instrument, and these quotations are repeated by the instruments in the offices throughout the city. These office instruments print the quotations in plain Roman letters and figures on a ribbon of paper, so that any one can read and understand them. Thus one man does the work formerly required of several hundred, and no time is lost in conveying the information. The broker in his office is informed of the transactions at the Exchange at the very instant they are made. IV. THE GOLD EXCHANGE. You pass from Broad street into the basement of a brown stone building just below the Stock Exchange, and find yourself in a long, dimly-lighted passage way, which leads into a small courtyard. Before you is a steep stairway leading to a narrow and dirty entry. At the end of this entry is a gloomy looking door. Pass through it, and you are in the famous Gold Exchange. This is a showy apartment in the style of an amphitheatre, with an ugly fountain in the centre of the floor. An iron railing encloses the fountain. Against the New street end is the platform occupied by the President and Secretary, and on the right of this is the telegraph office. There are two galleries connected with the room, one for the use of visitors provided with tickets, and the other free to all comers. There is an indicator on the outer wall of the building on New street, from which the price of gold is announced to the crowd without. It is a common habit with sporting men of the lower class to frequent New street and bet on the indicator. There are but few benches in the Gold Room. The members of the Board are too nervous and excitable to sit still, and seats would soon be broken to pieces in their wild rushing up and down the floor.
