"Why do you make all this noise?"

"Noise? May I not do what I like on board my own yacht? Wait a bit, and you'll see something which will perhaps astonish you."

The Englishman laughed triumphantly, and got up.

I also got up. I had a suspicion that our host, if I may call him so, was evilly disposed toward us. I had for some time felt that the ship was in motion; first, I thought it was the effect of the small waves which the passing steamers caused; but the last few minutes made it clear to me that the yacht was steadily leaning over on one side, and when both the Englishman and I got up, we could clearly hear the rippling sound that water makes when it is being forced aside by a ship in motion. "What do you think now, gentlemen?" The Englishman threw open the door to the cabin on the starboard side, opened the port-hole, and pointed out.

It was as I had suspected. The yacht had got under way, and was sailing out of the harbour to eastward, between the islands, as the wind did not admit of steering in a northerly direction. We were already about a quarter of a mile away from the anchorage.

"On our next tack we shall clear Tungendess," continued Mr. Howell, "and then you know for yourselves how far it is out to sea."

I looked at Monk, and I must confess my heart beat quicker than usual; but Monk smiled back in a manner which plainly said that nothing unexpected had happened.

Presently a great whining sound cut through the air and forced its way through the open porthole in the cabin. Monk, with a friendly nod to the Englishman, asked:—

"What do you think that is?"

"It is the grey gunboat, which is trying her steam whistle; but I promise we shall not be long troubled by her infernal noise; the wind freshens."
