f their clothes.

"Stop, for God's sake, stop!" cried Jack "The harbour is full of ground
sharks--it is, upon my soul!"

"Do you think to frighten us with ground sharks?" replied the coxswain,
"keep under cover, my lad; Jack, give him a shot to prove we are in
earnest, and every time he or that nigger show their heads, give them
another, my lads."

"For God's sake, don't attempt to swim," said Jack, in an agony; "I will
try some means to give you water."

"Too late now--you're doomed;" and the coxswain sprang off the rock into
the sea, and was followed by two other men: at the same moment a musket
was discharged, and the bullet whistled close to our hero's ear.

Mesty dragged Jack from the gangway, who was now nearly fainting from
agonising feelings. He sank on the deck for a moment, and then sprang
up and ran to the port to look at the men in the water. He was just in
time to see the coxswain raise himself with a loud yell out of the sea,
and then disappear in a vortex, which was crimsoned with his blood.

Mesty threw down his musket in his hand, of which he had several all

"By the powers, dat no use now!"

Jack had covered his face with his hands. But the tragedy was now

hid his face.

"I'm glad he no see dat, anyhow," muttered Mesty.

"See what?" exclaimed Jack.

"Shark eat 'em all."

"Oh, horrid, horrid!" groaned our hero.

"Yes, sar, very horrid," replied Mesty, "and dat bullet at your head
very horrid. Suppose the sharks no take them, what then? They kill us,
and the sharks have our body. I think that more horrid still."

"Mesty," replied Jack, seizing the negro convulsively by the arm, "it
was not the sharks--it was I--I who have murdered these men."

Mesty looked at Jack with surprise.

"How dat possible?"

"If I had not disobeyed orders," replied our hero, panting for breath,
"if I had not shown them the example of disobedience, this would not
have happened. How could I expect submission from them? It's all my
fault--I see it now--and, O God! when will the sight b
