It was precisely as he had said, for as Jim laid himself flat in a tangled mass of brier on the summit of the ridge, and wormed his way forward till he was able to obtain a clear view beyond, he saw that the country down below was green with jungle. A vast sea of waving treetops lay below him, broken only here and there where rocky ground effectively opposed the irresistible march of creepers and verdure. The sight was, in fact, most beautiful, for the leaves shimmered and displayed a thousand different shades of green beneath the sun's rays, while, far off to the left, there came the gleam and scintillation of light falling on water. "De lagoon," declared Sam without hesitation, tossing a finger to the front. "Not able to see de entrance, ob course, 'cos it too far away, and trees hide um; and not able to see where de riber lie for de same reason. But dat de lagoon. Sam stake him hat on it." "And those men we are after?" asked Jim, his eyes searching every foot of the huge green vista. "Dey down dar somewhere. Not see um wid all dose trees; but dere fo' sure. To-morrow we come up with them." Our hero lay for a while gazing all round and thinking deeply. The sight of the lagoon shimmering and flashing beneath the sun had reminded him of those natives with whom the two rascals they had formerly followed had struck up an acquaintance. Jim remembered that it was more than a simple acquaintance, for it had since been proved that Jaime de Oteros and his gang of evildoers had for long carried on an illicit trade in guns and spirit with the tribe in that neighbourhood. Obviously they were making in that direction to join hands with them, and, once there, how was Sadie to be recovered? "It will be harder than I imagined," he told himself despondently. "Once these men reach the natives with their prisoner, nothing but a battle royal and the defeat of the tribe can save her. If only I were near enough to come upon them before they could reach their friends." Again he lay silent and thinking, till Sam looked at his young master wondering. "Not good lie here and stare," he said. "Dat not de way to save de missie. S'pose we make right way down de hill and get into the jungle. Dey down dere, I say. To-morrow dey come up wid the black men we fight wid way ober by de lagoon." "And once there Sadie is almost lost to us," cried Jim, a tone of bitterness in his voice. "See here, Sam, I'm going to make a big effort. Tell me, can those fellows travel once the night falls? Can they push on towards those natives?"
