Four Young Explorers by Oliver Optic

In the afternoon of the second day out Professor Giroud called his pupils together in the library, which was the schoolroom of the ship, and resumed the lessons which had been interrupted since the arrival at Sarawak. The long intermission had sharpened the intellects of the class, and they were very earnest in their studies. But it could be only for the afternoon and the next day, for the commander was very diligent in the business of sight-seeing.

At half-past nine the next forenoon, the passengers were all assembled in Conference Hall, as the captain had appointed; and the siamangs, who spent much of the time aloft running up and down and along the foreyards, were in their usual places, for chairs had been provided for them; and they looked as grave and attentive as though they understood the whole of the lecture. Captain Ringgold appeared on the rostrum, after he had patted Mr. and Mrs. Mingo on the head, and glanced at Miss Mingo in the lap of Miss Blanche.
