,
boy; your brain is over-excited. Try once more to sleep."

Rob obeyed, feeling weak and hysterical; but after a few minutes sleep
came once more, and it was morning when he reopened his eyes.

CHAPTER TWENTY ONE.

"WHERE THERE'S A WILL THERE'S A WAY."

A glorious, a delicious morning, with the mists passing away in wisps of
vapour before the bright sunshine, the leaves dripping with dew, and
bird and insect life in full activity.

But it was everything for the eye and nothing for the inner man. Waking
from a most restful sleep meant also the awakening to a sensation of
ravenous hunger, and directly after to the terrible depression caused by
the loss sustained on the previous day and their position--alone, and
without the means of obtaining food.

When Rob started up he found Brazier in earnest conversation with
Shaddy, and in a few minutes the boy learned that their guide had been
about from the moment he could see to make up the fire, and then he had
been searching in all directions for traces of their companions.

"And you feel sure that they have gone?" Brazier was saying when Rob
joined them.

"Certain sure, sir."

"But I still cling to the belief that we have blundered into the wrong
place in our weariness and the darkness last night. Why, Naylor, there
must be hundreds of similar spots to this along the banks of the river."

"Might say thousands, sir; but you needn't cling no more to no hopes,
for this is the right spot, sure enough."

"How do you know?" cried Rob.

"'Cause there's the mark where the boat's head touched ground, where we
landed, and our footmarks in the mud."

"And those of the men?" cried Brazier hastily.

"No, sir; they none of them landed. There's your footmarks, Mr Rob's,
and mine as plain as can be, and the water has shrunk a bit away since
we made 'em yesterday. No, sir, there's no hope that way."

"Then what ever are we to do, man?" cried Brazier.

"Like me to tell you the worst, sir?"

"Yes, speak out; we may as well know."

Shaddy was silent for a few moments, and then said,--

"Well, gen'lemen, those fellows have gone off with the boat and all in
it. The guns and things was too much for 'em, and they've gone to feast
for a bit and then die off like flies. They'll never work enough by
themselves to row that boat back to Paraguay river, for one won't obey
the other. They'll be like a watch without a key."

"Then they have gone down the river?" said Ro
