"Whew!" whistled Mr. Manton, gazing after the retreating form in amazement. "There's a bit of dynamite for you! Pride and poverty mixed in equal parts do make a most powerful explosive. However, I haven't forgotten my own days of poverty, and can fully appreciate the boy's feelings. I'll try him on a different tack as soon as this little squall has blown over. He and his mother must be different from the majority of the people down here, for they are the first we have met who don't seem to want to make money out of us."

Mr. Tracy Manton had no idea of giving up his purpose of engaging Sumner to accompany them on their trip, for he was the kind of a man who wins his way by sticking to whatever plan he has decided upon, in which respect his nephew Worth strongly resembled him. So the next time he met the lad, which was in the afternoon of the following day, he held out his hand and said: "I beg your pardon for my unintentional rudeness of yesterday, and my forgetfulness of the fact that a gentleman is such, no matter where he is found. Now, I want you to forgive me, forget my offence, and do me a favor. I can't make head or tail of our sails, and they don't seem to me right somehow. If you will come and look at them I shall be greatly obliged."

By this time Sumner was so heartily ashamed of his conduct of the day before that he was only too glad to accept this overture of friendship, and a few minutes later the two were busily discussing the sails of the Cupid and Psyche, as the Mantons' canoes were named. The spars were much heavier than they need be, while the sails were of the ill-shaped, unserviceable pattern generally furnished by canoe builders, and these defects were quickly detected by Sumner's experienced eye. When he pointed them out to Mr. Manton, the latter readily comprehended them, but was at a loss how to make the improvements that were evidently demanded.

In order to explain more thoroughly the idea that he wished to convey, Sumner dragged out his own canvas canoe, stepped her masts, and hoisted her sails. They were of a most ingenious and effective lateen pattern, such as Mr. Manton had never before seen.

"Where did you get hold of that idea?" he asked, after studying them carefully a few moments. "It is a capital one."

"I got it partly from an Arab dhow that I once saw off Madagascar, and partly from the feluccas at Civita Vecchia."

"Madagascar and the Mediterranean!" repeated Mr. Manton, in astonishment. "If you have visited both of those places you must have travelled extensively."

"Yes," answered Sumner, quietly, but with a twinkle of amusement in his eye. "The son of a naval officer who attempts to follow his father about the world is apt to see a good bit of it before he gets through."

Mr. Manton, who had known nothing of Sumner's history, no longer wondered that he had been offended at being taken for a boatman whose services could be hired. He was, however, too wise to make further mention of the subject, and merely said,
