body bending and swaying about as he ran.

Then he jumped and jumped again, and the doctor shaded his eyes with his
hands.

"He has got into a swampy patch," he said. "Of course. There's a bit
of a stream runs along there, and--"

"Ow!" came in a dismal yell, followed by a furious barking, as we saw
Jack make a tremendous jump, and then disappear.

"Help, help!" came from among some dense green growth, and hurrying
forward we at last came in sight of our companion, at least in sight of
his head and shoulders, and we could not approach him, for the ground
gave way beneath our feet, the bright green moss almost floating upon a
treacherous bog.

"Hold on!" shouted the doctor; "we'll help you directly;" and taking out
his big knife he began to hack at some small bamboos which grew in thick
clumps about us.

"Make haste," moaned Jack, "I'm sinking;" and we could see Gyp, who was
howling furiously, tearing at the soft moss as if to dig his master out.

"Give Jimmy knife," said the black, who was grinning and enjoying Jack
Penny's predicament.

I handed him mine, and he too cut down armfuls of the young green
bamboo, the carriers coming up now and helping, when, taking a bundle at
a time, Jimmy laid them down, dancing lightly over them with his bare
feet, and troubling himself very little about danger, as he made a sort
of green path right up to Jack.

"His black fellow pull up," shouted Jimmy; but I ran up to where he was,
and each taking one of Jack's hands he gave a wriggle, floundered a bit,
and then we had him out covered with black mud; and though we were
standing up, he would not trust himself just then erect, but crept after
us on hands and knees, the soft bog beneath us going up and down like a
wave.

As soon as he was quite safe there was a hearty laugh at Jack Penny's
expense; and the doctor drily asked for the butterfly.

"Oh, I caught him," said Jack; "but I lost him when I trod on that great
beast."

"What great beast?" I said.

"Crocodile fifty foot long," drawled Jack.

"Say sixty," said the doctor.

"Well, I hadn't time to measure him," drawled Jack. "I trod upon one,
and he heaved up, and that made me jump into a soft place, and--ugh!
what's that?"

I was very doubtful about Jack's crocodile, but there was no mistake
about the object that had made him utter this last cry of disgust.

"They're pricking me horrid," he shouted; and we found that he had at
least twenty large leeches bu
