three in the
afternoon
The schoolroom , which had been made of the after cabin , and contained the extensive library of the ship , had been deserted for several weeks so far as its regular use was concerned . Miss Blanche , Louis , Morris , and Scott formed a class , or rather several of them , and pursued their studies systematically under the professor ; but they had been interrupted by the visit to Egypt and the trip to Cyprus , and their work was not resumed till the ship sailed from Suez . The recitations and the study were not confined to the classroom , but some of them were given on deck and in the cabin to individuals as the convenience of both permitted ; and some of the hours of the first two days had been used in this manner . `` Now you can see Yembo , '' said the commander at half-past three in the afternoon , as he pointed out a town on the shore of Arabia . `` The name is spelled in so many different ways it is hard to find it in the books . Sometimes it is Yembo , Yanba , and Yembu , and again it is Zembo , Zambu , and Zanba . It is Yembo on my charts , and for that reason I use it .
