Sometimes the perusal of a volume starts off the reader upon a career that is really different from that which the book describes. By its hints or suggestions, it awakens the powers to some incidental subject, upon which they seize with an earnestness and devotion that cannot fail of success. Thus, when William Carey read the "Voyages of Captain Cook," he first conceived the idea of going upon a mission to the heathen world. There was information imparted in that volume, which, in connection with the marvellous adventures and success of the great voyager, fired his soul with the determination to carry the gospel to the perishing.

Nat had such a mind, and difficulties rising mountain high could not hinder him from examining a subject that absorbed his thoughts. A walk of ten miles to see a book, the sacrifice of an evening's entertainment at a party of pleasure, or the loss of a night's sleep, never stood between him and the information he earnestly desired. His unwavering purpose surmounted all such obstacles in the attainment of his object.


CHAPTER XXV.

EULOGY BY JOHN QUINCY ADAMS.

One of the brief periods in which Nat worked at his trade, after he commenced to study more systematically, was spent on the Mill Dam in Boston. At a machine-shop there, he pursued his business a short time, for the purpose of earning the means to defray his expenses while studying.

"John Quincy Adams is to deliver a eulogy on Madison at the old Federal Street Theatre to-morrow," said one of the hands.

"At what time?" inquired Nat.

"Ten o'clock is the time announced for the procession to form. It will probably be twelve o'clock before they get ready for the eulogy."

"I would go," said Nat, "if I had my best clothes here. I could go without losing much time at that hour."
