One of the guards tossed restlessly and woke up cursing. "Shut up that whistling," he shouted, "that blooming thing gets on my nerves."

Walter had no option but to obey, but the awesome tune had carried its doleful message. The mournful notes had reached the ears of the wounded lad in the canoe. Its message was plain to him. Walter was a captive, or in great danger. And now began a contest between will-power and pain and weakness from which many a man would have shrunken.

Three times Charley struggled to rise to his feet, only to sink back exhausted with great beads of sweat standing out on his brow. At last, abandoning the attempt, he began to wriggle back towards the stern of the canoe. His progress was slow and painful, and even in the short distance to be covered, he had often to lay quiet and rest. At last he succeeded in reaching the stern, but here his difficulties were by no means ended. Working awkwardly with his left hand he managed to draw his hunting-knife and slash open the pack of provisions they had brought with them. From these he selected a can of milk. It was slow work opening it with one hand, but at last he succeeded in removing the top. Part of the contents he swallowed as it was, the balance he diluted with water and broke hardtack up in it. By the time he had finished the food, a little color had crept back into his face. He was still very weak, however, and another attempt to rise met with failure. For a few minutes he lay quiet thinking, then rummaging in the pack he brought forth a pint bottle of brandy. With repugnance written on his face, he took several swallows of the fiery liquor. It ran through his veins like fire. Shoving the bottle into his pocket, he succeeded in staggering to his feet and slowly pulled himself up on one of the mangrove's roots, and, pausing frequently to rest, gradually worked his way to the shore.

Walter's captors slept heavily until the noon hour, when they awoke, stirred up the fire, and prepared some dinner; but they offered none of it to the unfortunate lad, who watched its preparation with hungry eyes. Their repast finished, the two ruffians enjoyed a long smoke, after which they played a few games of cards which ended in a violent dispute that nearly resulted in blows.

As the afternoon wore on without the appearance of the party they were expecting, they again composed themselves to slumber. Slowly the afternoon wore away and the two outlaws still slept on. The sun went down and night began to fall and still the two showed no signs of awakening.

Suddenly Walter felt the bonds that held him slip to the ground and Charley's voice whispered, "Drop on all fours, Walt, and work your way back into the thicket."

Walter did as he was bid as quickly as his stiffened limbs would permit and soon caught up with his chum, who had begun to retrace his steps as soon as he had severed the captive's bonds. In fact, he dared not wait or tarry, for the false strength engendered by the brandy was fast leaving him. To give out on the way would be fatal to both. He must reach the canoe before the last remnant of his strength gave out or all was lost.

Slowly the two boys wormed their way through the jungle, expecting every second to hear the sounds that would indicate that the prisoner was missed and pursuit begun.

At last they reached the clump of mangroves that concealed the canoe. Here outraged nature claimed its due and Charley sank on the edge of the shore unable to go further. It required nearly all of Walter's remaining strength to drag his insensible chum over the roots and lower him into the canoe. Precious as was each moment lost, Charley demanded instant attention, his wound had broken open again from his exertions and his tattered shirt was wet with blood. Walter stuffed bits of cloth into the hole and bound it up as well as he could in the darkness. This labor completed, he cast loose the canoe, and with a few strokes of the paddle sent her over to the other side of the stream. Here he laid aside his paddle and sank back to rest and think. The friendly darkness completely hid them from the gaze of anyone on the point. Until the moon rose they were as safe there as any place on the river. The plucky lad sorely needed rest and refreshment. For two days and a night he had been without sleep and for twenty-four hours without food. This, with the strenuous labor and excitement through which he had passed, had rendered him nearly as weak as his unconscious companion. Sleep was out of the question until they were safe from their enemies, but food was handy and he lost no time in making a hearty meal on a can of corned beef, crackers and a tin of milk. The repast brought fresh strength and courage, although his head felt very heavy and he could hardly keep his eyes open.

With the outlaws ahead and behind them, there was little choice of the direction in which they should flee, and Walter paddled steadily on up the river, keeping close to the opposite shore from the convicts.
