"I never noticed that chant much," said Ralph: "it means a lot more than it used to. I wonder why?"

"Bless your heart, boy! you've got more feelin' in your soul now, and more thoughts in your head. I tell you that's a psalm that has to grow on you. It don't mean nothin' particular to folks that haven't had trouble, but to them that have, it keeps growin' and growin', until they see more and more in it every time they think of it. I say that psalm over and over to myself when I'm sittin' here o' nights with my hand on the helm, but I never knew it could be sung. I used to sing once; I wonder if I could learn that. I'd give 'most anything to do it."

"Why, of course you can," exclaimed Ralph. "See here, it is just as easy;" and he hummed the first line. "Strike right in and sing it with us."

The two boys sang the chant again and again, until the captain had mastered it; and during the day he hummed it as he worked, resolving in his joy over his success that he would go out of his way to do those lads a favour, but it should be a surprise, and he would not tell Marcus even of his intention.

It proved a fine day for fishing. School after school of mackerel came by, and the boys worked industriously, helping the fishermen to gather their harvest. At night, tired and sleepy after their unusual labours, they went below early, and the captain, with a wink and crook of his finger at Marcus, beckoned him to his side.

"That's Whaleback yonder."

"Yes, I know it is; what of it?"

"There's a good breeze."

"Yes."

"I'm going to make for that island, and anchor off the south end, where the beach is."
