"Because the chances are that we should find, either at Barbados or St. Lucia or Dominica—or, in fact, at any of the other islands, one of our frigates, or at any rate, some officer senior to me; and in that case, as we have no fixed orders from the admiral, we might be detained or sent off in some direction that might not suit us at all."

"Good!" Doyle said. "It is always a safe rule to keep out of the way of a bigger man than yourself. I have always observed that a captain of a man-of-war or of a frigate is sure to be down on small craft, if he gets a chance. It is like a big boy at school fagging a little one; he could do quite as well without him, but it is just a matter of devilment and to show his authority. Heaven protect us against falling in with a frigate. If she were a Frenchman she would sink us; if she were a Britisher she would bully us."

They reached the ground on which Nat had decided to cruise. Three days later the look-out at the mast-head shouted "Sail ho!" the words acting like an electric shock to those on deck.

"How does it bear?"

"About east by north, sir. There are three vessels; I can only see their topsails at present. Two of them are a bit bigger than the third. They look to me to be merchantmen. I should say the other, by the cut of his sails, is a Frenchman."

A low cheer broke from the men. "Now, if that fellow brings news that war is declared, we are in luck," Nat said. "Either he is convoying two French merchantmen he has overtaken, or he has two British prizes he has picked up. If they are English, we shall not get so much prize-money; but then we shall have less difficulty with the privateer, if privateer she is, because she must have put a good many of her hands an board the prizes. So we can in either case count upon doing well. At any rate they are not likely to suspect that we are English, being French-built and French-rigged. Even if they have a doubt, they will be satisfied as soon as they see the name on our bows. We will not get up any more sail."

"I will go up and have a look at her," Turnbull said; and slinging his glass over his shoulder he went aloft.

"I think," he called down, after a long look at them, "that the middle ship is a good deal larger than she looks; and the others are carrying every stitch of canvas, but she has neither royals nor topgallant-sails. Her yards have a wide spread, and I am inclined to think that she is a frigate or a large corvette—certainly a French one. As to the others, I cannot say with certainty, but I rather fancy they are English; in which case she has captured them on the way, and, being much faster than they are, has to go under easy sail to keep with them."

"Well, I hope she is not too big for us," Nat said, as Turnbull rejoined him.

"What should you call too big, sir?" Turnbull asked with a smile.
