Street. The driver wore a fur-cap and a great-coat buttoned up around his ears. As he turned the corner to the -------- Building, he glanced down at his front wheel and brought his horses up with a jerk. There was evidently something wrong with the wheel, for he jumped down from the box to examine it. He shook the wheel, took off the tap, and began to move the hub carefully out toward the end of the axle. As he worked he kept his eyes on the corner. Presently a big, plainly dressed man walked slowly down by the building. He carried a half-open newspaper in his right hand and seemed to be keeping a sharp lookout around him. He stopped for a moment by the carriage, satisfied himself that it was empty, and went on. At the next corner he climbed up on the seat of the waiting patrol wagon and disappeared. The cabman seemed to be engrossed with the repair of his wheel and gave no indication that he had seen the stranger. Almost immediately thereafter a second man passed the corner with a newspaper in prominent evidence. He was a "hobo" of the most pronounced type and marched by with great difficulty. After he had passed, he turned round and threw the newspaper into the gutter with a volley of curses. The cabman worked on at his wheel. He had now removed it to the end of the axle and was scraping the boxing with his knife. At this moment a young man wearing a gray overcoat and a gray slouch hat came rapidly down the street. At the corner he put his hand quickly into his overcoat pocket, took out a newspaper, and immediately thrust it into his other pocket. The cabman darted across the street and touched him on the shoulder. The man turned with a quick, nervous start. The cabman took off his cap, said something in a low tone, and pointed to his wheel. The two men crossed to the carriage. The cabman held the axle and the stranger slipped the wheel into place, while the two talked in low tones. When it was done, the stranger turned round, stepped up on the pavement, and hurried on by the building. The cabman shut his door with a bang, climbed up on his box, and drove rapidly down -------- Street. III. Parks," said Randolph Mason, taking off his great-coat in the private office, "who wanted to see me at this unusual hour?" "He was a Philadelphia man, he said, sir," answered the little melancholy clerk. "Well," said Mason, sharply, "did he expect to die before morning that I should be sent for in the middle of the night?" "He said that he would leave at six, sir, and must see you as soon as possible, so I thought I had best send for you." "He is to be here at ten, you say?" "At ten, sir," answered the little man, going out into the other office and closing the door behind him. When the door was closed, Parks went over to a corner of the room, took up a hackman's overcoat and fur cap, put them into one of the bookcases and locked the sliding top. Then he went quietly out of the room and down the steps to the entrance of the building.
