ogged to burn," said the captain.

"We will try to blow her up, Captain," cried Jim. "She is a dangerous
proposition so near to the coast."

"It's a good idea, lad," agreed the captain.

"Lower the boat, my hearties," ordered Jim with a grin.

They put two kegs of powder into the boat, and with the material for a
couple of long fuses, they started for the derelict, now but a short
distance off. None of the boys will ever forget that boarding of the
abandoned vessel, not on account of the danger, for there was none,
but for the unusualness of the occasion and the picturesqueness of the
scene.

The sun was just setting as they rowed towards the _Maria Crothers_,
or what was once that gallant vessel, and the crimson glow came over
the slow-rolling swell and touched everything with a lurid light,
especially the desolate derelict. As they were nearing the hulk, Tom
exclaimed:

"Look, there is a shark coming out from a hole under her bow!"

Sure enough, with sinuous motion a long and ugly-looking shark swam
slowly a short distance below the surface, taking on a greenish hue,
from the color of the water. There was something singularly repellent
about him and peculiarly sinister in his every motion.

"If he gets too sassy, we will treat him like we did his friends and
brethren near the coast of Maine," said Jim. "When we were in the
canoes. Remember, Jeems?"

"Don't mention it to me," warned Jeems. "I'm liable to have a chill."

It was not difficult to board the derelict, when the boat was brought
on the lee side, for the vessel was down well with the water. Jim
jumped aboard and the others followed, except old Pete, who was at
the oars; he kept the boat close while the barrels of powder were
transferred.

The boys found nothing on the old craft of especial interest. They
could still see that the cabin had been a handsome one, with dark wood
like mahogany and properly gilded, but everything was now mildewed or
covered with green slime. There were sea things crawling everywhere.

Jim found his work cut out for him to get the powder planted where it
would do the best execution. Darkness came on, and he was busy aft
with one keg while Juarez and the engineer were planting the other
for'ard. They had got a number of lanterns from the ship to work by,
and, from a distance they looked like glow worms on the dark surface
of the waters.

It was a most weird and peculiar sight, but after nearly two hours'
work, everythi
