They were alone upon the sea, with but a plank between them and death; with no means of helping themselves, with only enough food for one day, and the sharks swimming around them in sure certainty of their meal sooner or later.

One of the seamen took hold of the end of the towline, and held it up for the rest to see.

It had been severed with a knife! It had not been so rotten as to give of its own accord from the strain put upon it; it had not frayed itself, or broken at any weak spot, it had been cut.

They had been cast adrift by their own companions, of malice prepense.

"God forgive him!" ejaculated Mr. Gilchrist.

"Who?" gasped Ralph.

"The unhappy wretch who did this."

Ralph made no further remark; there was but one among the boat's crew who was malicious enough to be even suspected of such a crime, and the boy could not bear to think it of him. But that somebody had severed the rope, was beyond doubt.

The fierce sun blazed down upon the waste of water, there was nothing to be done but to sit still and bear it. Their limbs were cramped from their inability to change their positions, there was no help for that. Raging headache came on; there was a small tin pail, and Wills tried to dip up sea-water and cast it over Mr. Gilchrist's fevered brow. With the first movement such a rush of sharks was made to the place as caused them all to shudder. What had they expected that they snapped so eagerly at the pail?

The men were hungry, but thirst overpowered hunger, and they must economise their little stock of biscuit and water. For how many days would it avail to keep life in them were they not picked up?
