"It has, indeed, a braver man never stepped, nor a better officer; but you see they have certain rules in the service, and everything is sacrificed to maintain them. I can't think what keeps him; he went last night and said he would pull up to the Temple stairs, because he wanted to call upon somebody by the water-side, and after that he was going to the city to transact some business of his own, and that would have brought him nearer here, you see; and there are plenty of things coming down the river."

"He's coming," cried the other; "don't be impatient; you will see him in a few minutes."

"What makes you think that?"

"Because I see his dog—there, don't you see, swimming in the water, and coming towards the ship."

"I cannot imagine—I can see the dog, certainly; but I can't see Thornhill, nor is there any boat at hand. I know not what to make of it. Do you know my mind misgives me that something has happened amiss? The dog seem exhausted. Lend a hand there to Mr. Thornhill's dog, some of you. Why, it's a hat he has in his mouth."

The dog made towards the vessel; but without the assistance of the seamen—with the whole of whom he was an immense favourite—he certainly could not have boarded the vessel; and when he reached the deck, he sank down upon it in a state of complete exhaustion, with the hat still in his grasp.

As the animal lay, panting, upon the deck, the sailors looked at each other in amazement, and there was but one opinion among them all now, and that was that something very serious had unquestionably happened to Mr. Thornhill.

"I dread," said the captain, "an explanation of this occurrence. What on earth can it mean? That's Thornhill's hat, and here is Hector. Give the dog some meat and drink directly—he seems thoroughly exhausted."

The dog ate sparingly of some food that was put before him; and then, seizing the hat again in his mouth, he stood by the side of the ship and howled piteously; then he put down the hat for a moment, and, walking up to the captain, he pulled him by the skirt of the coat.

"You understand him," said the captain to the passenger; "something has happened to Thornhill, I'll be bound; and you see the object of the dog is to get me to follow him to see what it's about."
