John Mangles understood his business. Though he was only the captain of a pleasure yacht, he was one of the best skippers in Glasgow. He was thirty years of age, and his countenance expressed both courage and goodness, if the features were somewhat coarse. He had been brought up at the castle by the Glenarvan family, and had turned out a capital sailor, having already given proof, in some of his long voyages, of his skill and energy and _sang-froid_. When Lord Glenarvan offered him the command of the DUNCAN, he accepted it with right good will, for he loved the master of Malcolm Castle, like a brother, and had hitherto vainly sought some opportunity of showing his devotion.

Tom Austin, the mate, was an old sailor, worthy of all confidence. The crew, consisting of twenty-five men, including the captain and chief officer, were all from Dumbartonshire, experienced sailors, and all belonging to the Glenarvan estate; in fact, it was a regular clan, and they did not forget to carry with them the traditional bagpipes. Lord Glenarvan had in them a band of trusty fellows, skilled in their calling, devoted to himself, full of courage, and as practiced in handling fire-arms as in the maneuvering of a ship; a valiant little troop, ready to follow him any where, even in the most dangerous expeditions. When the crew heard whither they were bound, they could not restrain their enthusiasm, and the rocks of Dumbarton rang again with their joyous outbursts of cheers.
