"You hold on," he muttered to the great negro; "we make a monkey-bridge and save them all."

Hen only nodded his head and took a double turn of the lianas around each arm. Professor Ditson was the next one to win safety, for the two boys were staying by Jud, who was a most indifferent swimmer. As the professor's long, thin legs dangled out into the current like a pair of tongs, with a desperate stroke Will caught one of his ankles, and was gripped in turn by Joe, and Jud locked both of his arms around the latter's knees, while the swift river tossed his gray hair and beard along its surface. As the full force of the current caught this human chain it stretched and sagged ominously. Then each link tightened up and prepared to hold as long as flesh and blood could stand the strain.

"Go ahead, Jud!" gasped Will over his shoulder; "pull yourself along until you get to shore; then Joe will follow, and then I. Only hurry—the professor won't be able to hold on much longer, nor Hen to stand the strain."

"Don't hurry on my account," sounded the precise voice of Professor Ditson above the roar of the waters. "I can hold on as long as any one." And as he spoke Will felt his gaunt body stiffen until it seemed all steel and whipcord.

"Same here!" bellowed Hen, his magnificent body stretched out through the water as if on a rack. "Take your time and come along careful."

In another minute the old trapper had pulled his way hand over hand along the living bridge until he too had a grip on one of the dangling lianas. He was followed by link after link of the human chain until they were all safe at the edge of the bank. Hen was the first to scramble up and give the others a helping hand, and a moment later all six of the treasure-seekers stood safe on the high ridge of the little promontory and sadly watched the boat which had borne them so well smash into a mass of floating, battered planks among the rocks and disappear down the current. Along with it went their guns, their ammunition, and their supplies.

Jud alone retained the automatic revolver which he always wore, with a couple of clips holding sixteen cartridges, besides the eight in the cylinder. Hen also could not be termed weaponless, for he still wore his machete; while Will had a belt-ax, Joe a light hatchet, and Professor Ditson a sheath-knife. Besides these, the Indian had his bamboo tinder-box and flint and steel, which he always wore in his belt. These and the jack-knives and a few miscellaneous articles which they happened to have in their pockets or fastened to their belts comprised the whole equipment of the party.

Before them stretched a hundred miles of uncharted jungle, infested by dangerous beasts and wandering cannibal tribes, through which they must pass to reach the old Slave Trail. Half that distance behind them was the Amazon. If once they could find their way back to that great river and camp on its banks, sooner or later a boat would go by which would take them back to Manaos. This, however, might mean weeks of delay and perhaps the abandonment of the whole trip. As they stood upon a white sand-bank far enough back from the river so that the roar of the rapids no longer deafened them, it was Pinto who spoke first.

"Master," he said to Professor Ditson, "it is no time for council. Let us have fire and food first. A man thinks more wisely with his head when his stomach is warm and full."

"I'll say the man is right," said Jud, shivering a little in his wet clothes as the coolness of the approaching night began to be felt through the forest; "but where is that same fire and food goin' to come from?"
