It was not long before his fame reached the ears of the master, who sent for Mr.Jolter, communicated to him the informations he had received, and desired him to check the vivacity of his charge, and redouble his vigilance in time to come, else he should be obliged to make a public example of his pupil for the benefit of the school.
The governor, conscious of his own unimportance, was not a little disconcerted at this injunction, which it was not in his power to fulfil by any compulsive means.

He therefore went home in a very pensive mood, and after mature deliberation, resolved to expostulate with Peregrine in the most familiar terms, and endeavour to dissuade him from practices which might affect his character as well as interest.

He accordingly frankly told him the subject of the master's discourse; represented the disgrace he might incur by neglecting this warning; and, putting him in mind of his own situation, hinted the consequences of the commodore's displeasure, in case he should be brought to disapprove of his conduct.
These insinuations made the greater impression as they were delivered with many expressions of friendship and concern.

The young gentleman was not so raw, but that he could perceive the solidity of Mr.
Jolter's advice, to which he promised to conform, because his pride was interested in the affair, and he considered his own reformation as the only means of avoiding that infamy which even in idea he could not bear.
His governor, finding him so reasonable, profited by these moments of reflection; and, in order to prevent a relapse, proposed that he should engage in some delightful study that would agreeably amuse his imagination, and gradually detach him from those connections which had involved him in so many troublesome adventures.

For this purpose, he, with many rapturous encomiums, recommended the mathematics, as yielding more rational and sensible pleasures to a youthful fancy than any other subject of contemplation; and actually began to read Euclid with him that same afternoon.
Peregrine entered upon this branch of learning with all that warmth of application which boys commonly yield on the first change of study; but he had scarce advanced beyond the Pons Asinorum, when his ardour abated; the test of truth by demonstration did not elevate him to those transports of joy with which his preceptor had regaled his expectation; and before he arrived at the forty-seventh proposition, he began to yawn drearily, make abundance of wry faces, and thought himself but indifferently paid for his attention, when he shared the vast discovery of Pythagoras, and understood that the square of the hypotenuse was equal to the squares of the other two sides of a right-angled triangle.
He was ashamed, however, to fail in his undertaking, and persevered with great industry, until he had finished the first four books, acquired plane trigonometry, with the method of algebraical calculation, and made himself well acquainted with the principles of surveying.
