He then would have had to go through the ordeal to which most who enter the naval service are exposed, which cannot be better explained than by comparing it to the fagging carried to such an iniquitous extent in public schools.
Mr Asper, for his own reasons, made him his companion: they walked the night watch together, and he listened to all Jack's nonsense about the rights of man.

And here Mr Asper did good without intending it, for, at the same time that he appeared to agree with Jack, to secure his favour, he cautioned him, and pointed out why this equality could not exist altogether on board of a man-of-war.
As for himself, he said, he saw no difference between a lieutenant, or even a captain, and a midshipman, provided they were gentlemen: he should choose his friends where he liked, and despised that power of annoyance which the service permitted.

Of course, Jack and Mr Asper were good friends, especially as, when half the watch was over, to conciliate his good-will and to get rid of his eternal arguing, Mr Asper would send Jack down to bed.
They were now entering the Straits, and expected to anchor the next day at Gibraltar, and Jack was forward on the forecastle, talking with Mesty, with whom he had contracted a great friendship, for there was nothing that Mesty would not have done for Jack, although he had not been three weeks in the ship; but a little reflection will show that it was natural.
Mesty had been a great man in his own country; he had suffered all the horrors of a passage in a slave ship; he had been sold as a slave twice; he had escaped--but he found that the universal feeling was strong against his colour, and that on board of a man-of-war he was condemned, although free, to the humblest of offices.
He had never heard anyone utter the sentiments, which now beat in his own heart, of liberty and equality--we say now, for when he was in his own country before his captivity, he had no ideas of equality; no one has who is in power: but he had been schooled; and although people talked of liberty and equality at New York, he found that what they preached for themselves, they did not practise towards others, and that, in the midst of liberty and equality, he and thousands more were enslaved and degraded beings.
Escaping to England, he had regained his liberty, but not his equality; his colour had prevented the latter, and in that feeling all the world appeared to conspire together against him, until, to his astonishment, he heard those sentiments boldly expressed from the lips of Jack, and that in a service where it was almost tantamount to mutiny.

Mesty, whose character is not yet developed, immediately took a fondness for our hero, and in a hundred ways showed his attachment.

Jack also liked Mesty, and was fond of talking with him, and every evening, since the combat with Vigors, they had generally met in the forecastle to discuss the principles of equality and the rights of man.
The boatswain, whose name was Biggs, was a slight, dapper, active little man, who, as captain of the foretop, had shown an uncommon degree of courage in a hurricane, so much so, as to recommend him to the Admiral for promotion.
