The secretary calls on a rival broker, and a plan is made to attack Logan’s holdings while he is out of communication with his office. Mr. Logan arrives in the South and is welcomed by Dick, who presents Elsie and quietly informs his father that she is the girl of his choice. The broker, who has made other plans, does not approve of the match, but keeps his own counsel. Meanwhile the attack on the market is commenced, and Logan’s office sends him a message, ordering instructions.
