Bert took the morning train to New York, and arrived about half-past seven o'clock. He met with no adventures on the way, and as soon as he reached the Grand Central Depot took a Fourth Avenue car down, as instructed by Uncle Jacob. In a large building of many stories on Nassau Street, on the sixth floor, was an office on the door of which Bert read

MAGNET MINING CO.

This, as he understood, was the office where Jacob Marlowe was employed.

Bert was considering whether he ought to knock or not, when a brisk-looking gentleman stepped up, and, opening the door, entered. Bert followed him in.

"Whom did you wish to see?" asked the brisk-looking man.

"Mr. Jacob Marlowe. Is this the office where he is employed?"

"Yes," answered the man, with a smile.

Bert hardly needed this assurance, however, as he had already discovered Uncle Jacob sitting in an inner room, at a desk, conversing on business, apparently, with an elderly man of dignified appearance.

"He will soon be at leisure," said the one who had just entered, and seated himself at another desk in the outer room.

"That must be Uncle Jacob's employer," thought Bert.
