"Sorry to trouble you; thanks," he said, when he had found it. Then leaning forward towards the gentleman opposite, he took out a packet of papers neatly tied up. "It's very provoking," he said. "I came down here on Saturday to get the governor's signature, and could not find trace or tidings of him. He left an hour before I arrived, and if I don't find him somewhere in town to-day, it will be a serious loss to our firm."

"You can afford it," the gentleman said, smiling.

"Yes; but our manager will be none the less angry about it. However, I can't help it;" and then they talked about the money market and other matters, till Bertie fell asleep again, and did not awake till they reached London Bridge. There Mr. Gregory saw him, and gave him a seat in his hansom, and the last thing Bertie saw as he left the platform was the gentleman with his little black bag in his hand, hurrying along as if for his life.

Bertie was very busy that morning: there were a great many letters to be addressed and notices copied out; his uncle seemed hasty and impatient, spoke harshly, and once or twice said he believed Bertie had left his brains in Brighton. Then the office was very stuffy and gloomy, for though the day was bright enough outside, very little sunshine found its way through the dusty ground glass windows of the office in Mincing Lane. Never in his life had Bertie so longed for luncheon-time; his head ached, and more than once a great lump seemed to grow suddenly in his throat as he thought of his past holidays; but the City at luncheon-time is not the best possible place for dreaming or moping, and before he had gone a hundred yards from the office door he came into violent collision with a gentleman running down the steps of another office, who, without pausing even to apologise, sprang into a cab that was waiting, without observing that he had dropped a small leather bag he held in his hand. Bertie, whose hat had been knocked off in the encounter, stooped to pick it up, picked up the bag at the same time, and glanced at the hansom fast disappearing amongst the crowd of others. It was no use to shout, much less to run, but having begun to learn to think, he acted with a good deal of decision. Hailing another cab that chanced to be near, he bade the driver follow the one that had just started, as the gentleman had dropped something, and the cabby, who had witnessed the whole transaction, nodded and drove on; but a few minutes had been lost; the first vehicle was a private one, with a good horse, Bertie's was a worn-out old creature, that ought not to have been in harness at all, so that it was just as much as the driver could do to keep it in sight. In the City, owing to several blocks, they almost lost it; and when they got into more fashionable regions amongst the less-frequented streets and quiet squares of the West End, matters were still worse, but at length, turning suddenly round a corner, they saw the identical cab standing before a large, gloomy-looking house, and its occupant speaking hurriedly to another gentleman on the steps. Bertie sprang out and ran up, flushed, breathless, and excited.

"If you please, sir, you dropped this in Mincing Lane," he said, "and I followed you as quickly as ever I could."

One of the gentlemen uttered a little cry of dismay, and almost staggered against the railing for support. In his hurry and confusion, his eagerness to deliver a pressing message, and get the documents back to the City, he had not discovered their loss at all. The other gentleman caught the boy by the arm, and then uttered an exclamation of still greater astonishment. "Oh! Bertie Rivers, I see. So you found my clerk's bag?"

"Yes, sir," Bertie replied, very much surprised to discover in the same moment that one speaker was Mr. Murray, the other the gentleman who had come up in the train with him that morning, the bag the very one that had excited his curiosity on two previous occasions, and caused him to be disturbed from his pleasant dream.

"How did you know the person it belonged to? Why did you come here with it?" Mr. Murray asked, after a keen, searching glance at Bertie's face. He was a shrewd, suspicious old gentleman, who had been deceived many times in his life, much imposed upon, and therefore very cautious of whom he trusted. Still, Bertie Rivers' face was truthful and frank enough to satisfy anybody as he replied that he did not know in the least to whom the bag belonged; "but I was going to my luncheon, sir, and I ran against this gentleman; my hat got knocked off, and when I stooped to pick it up I saw the bag. I felt sure the gentleman dropped it, and I called; but he had driven off, so I just hailed another hansom, and told the driver to follow the one just started. He said, 'I saw it all,' and drove as quick as he could, and—that's all, sir."

"No, no, there's something more; you must tell me all about it presently," and Mr. Murray pushed Bertie before him into a magnificent library. "You sit there for ten minutes, while I see to this business," and he turned to the clerk, who had followed him. "Give me the papers, and while I sign them thank that lad. He has done you a good turn to-day."

The clerk thanked Bertie cordially, and at length Mr. Murray stood up, thrust the papers into the bag, and with a curious glance, which seemed to say plainly, "I'll see you later on about this," dismissed the man by a wave of his hand, then he turned to Bertie, and caught him glancing at the clock with much uneasiness.
