By 9:45 A.M. the Board is beginning to present a scene of animation. Of the 1100 members not more than 600 are in attendance, and often not more than 400; indeed, there are members who have never once entered the room. But the attendance is increased by the presence of some 230 pages in uniform, wearing five-year service stripes, of which the sleeve of the superintendent is adorned with eight; 30 telegraph operators, whose business it is to hurry from place to place gathering quotations as they occur, and sending them out over the ticker, and by 550 telephone clerks who occupy the long booths on the west wall, where private lines connect members with their offices. These clerks are not permitted to go on the floor. Their employers, who rent the telephones from the Exchange, pay $50 annually to the institution as a fee for each clerk. As their duties are extremely important, involving the transmission by ’phone of orders and reports that often run into millions, it will be seen that this small army of private line operators is of necessity highly trained. An instant’s relaxation or inattention, or a failure to transmit promptly and correctly the verbal messages entrusted to them, may conceivably lead to confusion and losses of great importance. At each of the sixteen posts in the room, from twenty to forty stocks are situated, and another group covers the north wall. Once a position is assigned to any security by the committee in charge, it is seldom moved elsewhere, and thus, although there are nearly six hundred different issues of securities, the broker soon learns the location of each one and turns automatically in that direction when an order reaches him. At each of the posts, and along the north wall, the specialists in these various groups of stocks are at work before the opening of the market, entering the day’s orders in their books, some with the rapid energy that betokens an active opening, others with an indifference that spells dulness in their particular line.
