Biff Brewster - Brazilian Gold Mine Mystery Part 10

Fortunately, none of them was. .h.i.t by that first spray of smaller stones. Whitman stumbled, but FABULOUS EL DORADO 129.

Jacome overtook him and helped him regain his footing. Then they had reached Mr. Brewster, who was blocking them from the side pa.s.sage where Biff thought he wanted them to go.

Instead, Biff's father now was rushing them beneath the overhanging cliff, where they huddled against the rocky wall and turned to witness the havoc that they had so narrowly escaped. From this hollow, open s.p.a.ce where Mr. Brewster had guided them, they watched tons of dirt and stone drop down in a solid curtain, only a dozen feet away, for the bulge of the cliff above was comparatively slight.

Yet it jutted enough to send the tremendous landslide cascading out beyond them, something on which Mr. Brewster had counted when he made his quick decision. But after the roar had finally subsided, Biff's father disclaimed any special credit for the rescue.

"I was close enough to see that this pocket offered us our only chance," stated Mr. Brewster. "As it was, your own prompt response saved your lives. Otherwise, you would now be under there."

Mr. Brewster gestured significantly to the mound of earth and rock that had piled many feet above their heads. Carefully, they worked their way up over it and down a long slant to the main ravine, which they followed back to the river.

On the way, they looked up to the brow of the great cliff, but saw no human figures there. They noted though, that the landslide had turned the ra- 130 .

vine into a dead-end, with no trace of the narrow pa.s.sage that angled off to the right, the route that they would have taken.

Back at the river, Biff's father sat on a pack and commented rather ruefully: "I guess this about ends our quest for El Dorado."

"I'm afraid so," Whitman agreed. "I've told you all along that Joe Nara was a phony."

"You mentioned a few reasons why you thought so," reminded Mr. Brewster. "But they were hardly sufficient, Hal."

"All right," retorted Whitman, "I'll add a few clinchers. Nara said his men were Wai Wai Indians, didn't he?"

"That's right."

"Well, the Wai Wais come from clear over in British Guiana, not from around here. And you remember those shrunken heads he showed us? To prove that Macus were around?"

Mr. Brewster nodded.

"Those were Jivaro heads," declared Whitman, "from somewhere up the Amazon itself. Macus don't shrink heads. All Nara wanted was to scare our bearers back to Santa Isabel and chase us off into the jungle. Right now, he's probably still down on the Rio Negro, making a deal with Serbot, somewhere near Piedra Del Cucuy, learning what the compet.i.tion has to offer-"

Whitman cut off, his mouth wide open as he looked downstream. The others turned and saw a dugout FABULOUS EL DORADO 131.

canoe approaching, with Joe Nara reclining comfortably against the pack bags in its center, while Igo and Ubi were paddling him up the Rio Del Muerte. Old Joe was smiling as he stepped ash.o.r.e, but he became solemn when he saw the accusing eyes that were fixed upon him.

"I don't wonder you're annoyed," apologized Nara. "I should have gotten here first-"

"You didn't expect us to get here at all," Hal Whitman broke in. "Those directions of yours were a oneway ticket over the falls on the Rio Del Muerte!"

"You tried to come down the river by boat?" Nara paused and stared at the rubber boats. "I didn't know you had these with you. I said to follow the river, that was all. Remember?"

"I remember," returned Mr. Brewster. "You also told us to go up through the gateway to the ravine-"

"No, I didn't!" interrupted Nara. "I said for you to come up through-"

"What would be the difference?"

"Why, if you came up through," explained Nara, "I would have been there to meet you. But if you had gone up through ahead of me"-he shook his head-"well, thank heavens, you didn't try it!"

"Why not?"

"Because the tribe that guards El Dorado would have let loose a landslide if they saw strangers coming their way. I was mighty glad to find you waiting here. I knew you couldn't have gone up through El Porto Del Diablo."

132 .

"But we did go up through."

As Joe Nara stared incredulously, Mr. Brewster described all that had happened.

"Now that the ravine is blocked," he finished, "I suppose you can't take us to your fabulous El Dorado."

"On the contrary," returned Nara, with a quick smile, "I can take you to the mine by the short way." He spoke to Igo and Ubi in dialect; then, as the Indians went to the split rock, Nara announced, "I told them to summon some bearers."

Igo and Ubi shouted up through the ravine, and their calls seemed to echo back. Soon, squatty Indians appeared from the Devil's Gateway until a dozen of them had lined silently in front of Joe Nara. Kamuka undertoned to Biff: "These are the men who pushed stones from hill."

"I figured that," said Biff. "I wonder whether they are surprised or sorry to see us still alive."

"They are neither. They think Nara has made us live again because we are his friends. They think Nara is El Dorado."

From the furtive glances that the squatty Indians gave toward the Brewster party, along with the way they were awaiting Nara's bidding, Biff decided that Kamuka had guessed right.

At Nara's command, the Indians did the unexpected. They began replacing the packs and other equipment in the rubber boats, while Nara suggested that Mr. Brewster and his party get on board. Then FABULOUS EL DORADO 133.

the Indians brought dugouts from the bushes, and soon they were all paddling up the Rio Del Muerte, with Nara's canoe in the lead.

The going was easy, for the current was sluggish here. After about two miles, Igo and Ubi drove Nara's dugout to a low bank where the jungle appeared to be the thickest. With their paddles, they raised a tangle of roots as they would a curtain, and worked the boat through.

The others followed into a channel wide enough to accommodate the rubber boats with ease. When the foliage had been dropped behind the final canoe, Biff looked back and saw that the mouth of this stream was as completely hidden as before.

They emerged from the jungle near a towering rock that looked like the one from which the Indians had launched the landslide. They pulled up the boats beside the stream and took to a steep trail that brought them up behind the rock, past the far end of the blocked ravine.

The trail climbed steadily, with more slopes rising ahead. Beyond them were mountain peaks, some looming blue and cloud-capped in the distance, overlooking a vast, unexplored region. The chunky bearers marched steadily onward, crossing logs over deep ravines and following ledges hewn in the mountainsides. Biff kept his eyes fixed on the backs of the trudging Indians to avoid any dizziness from looking below.

"We are now in the Parima Mountains," Joe Nara 134 .

told them. "This part of the range is in Venezuela."

"I know," acknowledged Mr. Brewster. "We crossed the border from Brazil soon after we left Piedra Del Cucuy."

"What about these Indians of yours?" Hal Whitman put in. "You say they are Wai Wais, Nara, but that tribe lives over in Guiana."

"The main tribe does," returned Nara, "but this one group remained here to guard the sacred mountain, where El Dorado is located. They believed that Daipurui, the Spirit of Evil, would go on a rampage if anyone found the mine."

"And how did you get around that?"

"I figured out a trick," chuckled Nara, "that made them think I was El Dorado himself, the original Golden Boy in person. So they took Lew Kirby and me up to the mine, the same way they're going now."

Single file, the Wai Wais were climbing steps cut in a cliff, gripping liana vines as handrails to balance the weight of their packs. As Biff began the climb, the bearers looked like big, bulging beetles crawling toward the skyline. One by one, they dropped from sight as did the others in the party. BifF learned the reason, when he reached a slanted ledge, like a niche hacked in the cliff, and found the Wai Wais squatting there.

Kamuka came just behind Biff, then others of the party, and finally Joe Nara. Evidently, the Wai Wais were awaiting him, for they began an odd chant that included the words, "El Dorado-El Dorado-" and FABULOUS EL DORADO 135.

continued as the shock-haired prospector strode past them.

Nara paused where the ledge burrowed at a slant into the cliff and beckoned for everyone to follow, which they did. They entered a gloomy mine shaft, so low that all members of the party had to stoop, except the boys. The Wai Wai bearers, already bending under their burdens, followed the route automatically, as though the pa.s.sage had been cut to their size.

Daylight showed where the shaft opened into a great cavern. There, the sun shone through cracks and other openings in the ceiling. It glinted on chunky rock walls that fairly burned with vivid golden yellow.

All the tales that Biff had ever heard of hidden treasure had suddenly become real. This was a wonderland of wealth, with glittering side shafts going deeper into the mountain, promising new finds for anyone who followed them. Kamuka, awed by the yellow glitter, asked in breathless tone: "How much you think this worth, Biff? A million cruzeiro-maybe?"

"A lot more, if it's gold ore," returned Biff. "But it's worth practically nothing if it is simply yellow quartz. A lot of that is found in Brazil, in places easier to reach than this. What's just as bad, it may be fool's gold."

"Fool gold? What is that?"

"A mineral called pyrite," exclaimed Biff, "usually iron, mixed with sulphur. It often fools people who 136.

think that it is gold. But it is more the color of bra.s.s than gold, and it leaves a green streak when you rub it on something smooth."

As Biff picked up a chunk of yellow rock to examine it, he caught a nod of approval from his father. Biff had repeated facts that Mr. Brewster had told him regarding metals. Now, Biff's father indicated a stretch of rocky wall, where patches of yellow shone from a background of milky white. He asked: "What do you make of this, Biff?"

"It looks like gold quartz for sure, Dad!" exclaimed Biff. "There's no chance of mistaking that. Or is there?"

"In this case, there is no mistake." Mr. Brewster was studying the milky quartz as he spoke. "Undoubtedly, this shaft was first mined centuries ago, for it resembles old Indian mines that I have inspected. But although it yielded gold years ago, I doubt that its wealth has even begun to be tapped."

"You're right about that," chuckled Joe Nara, who was standing by. "Look there-and there-and there-"

Nara had turned on a powerful flashlight, and with each announcement, he pointed its beam down another rough-hewn shaft that branched from the main corridor. Each time, the glare was reflected with a new burst of brilliance.

"The gold of El Dorado!" boasted Nara. "A mountain full of it and a lot more that cropped over, as I'll show you!"

CHAPTER XVI.

Surrounded!

FROM the great central room, Joe Nara led his companions down through a maze of shafts and tunnels. Each pa.s.sage joined with another, and frequently the links were steep steps worn smooth by the feet of native miners, hundreds of years before.

At intervals, daylight showed through shafts that had been driven down through the mountain to tap a vein of gold. Always, the pa.s.sages led finally into new corridors that glittered with rich ore. At last, a long straight tunnel brought the party out on the far side of the mountain, hundreds of feet below the starting level.

The slope was gradual here, featured by dirt gullies leading down to a gra.s.sy valley, with the jungle beyond. As they followed the bed of one dry stream, Joe Nara pointed to the sparkle in its sands.

"That's where I've picked up some of these," he chuckled, bringing some small gold nuggets from his pocket and displaying them in his open hand. "But 138 .

mostly I find them up some of the smaller stream beds. The gold just kind of oozes out of the mountain."

Near the bottom of the slope was a shallow depression that nestled like a bowl in the curve of the mountainside.

"That's where the lake was," declared Nara. "The lake where El Dorado used to take a dip and come out all covered with gold. It's dried up, now, but there's still plenty of gold down in those sands."

Mr. Brewster studied the lake bed carefully. Biff saw his father look beyond, as though following a sandy course that led down to the gra.s.sy area that fringed the jungle.

"You are probably right," Mr. Brewster told Nara. "The lake was artificially formed, and once the dam was broken, the water found its way down into the jungle."

"And it joined a stream there," added Nara, "as I'll show you. Do you know why this all happened?" Tilting his head, he darted one of his birdlike glances at Whitman, then back to Mr. Brewster. "I'll tell you why. When the Indians found that the Spaniards and the English were going after El Dorado as well as after each other, they closed up shop.

"That's what they did. Just closed up shop. They busted the dam and got rid of the lake, so n.o.body could find it. They covered over all the shafts so n.o.body could find them either. They started rumors about El Dorado being somewhere else, to send all SURROUNDED! 139.

the explorers on a wild-goose chase. Then they kept guard over the real El Dorado to scare away anybody who stumbled on it by mistake."

"All quite logical," agreed Mr. Brewster. "That is the way the Indians would act." He turned to Whitman and asked: "You agree, don't you, Hal?"

"I agree," nodded Whitman. "Now I know why Nara showed us those shrunken heads. He did want to scare our bearers so they would run back to Santa Isabel. But it was because his Wai Wais would have made trouble if we brought a strange tribe here."

"They made trouble enough as it was," declared Nara, with a dry chuckle. Then, turning to Mr. Brewster, he said, "Let's see what's left of that map Lew Kirby gave you. Then we can figure what to do next."

Mr. Brewster produced the torn corner from the map. It showed the mine, the stream bed, the lake, and the trail that continued into the jungle, where it reached a river that was marked on the map.

"The route is an easy one," stated Nara, "as you can see. But first, I want you to estimate the value of the mine. Then pick out the ore you want, so we can take it to the river. From there, we will go downstream to the Casiquiare Ca.n.a.l and work our way through to the Orinoco River."

They camped that night beneath the trees that fringed the jungle. The next day, Mr. Brewster returned to the mine and studied it in detail. They stayed in the same camp another night and on the 140 .

following day, the Indians brought down loads of ore that Mr. Brewster had selected.

Those loads were carried several miles through the jungle to the river that Nara had mentioned. Biff and Kamuka helped make a new camp there. Then they swam in the river while they waited for the Indians to bring the packs. The water was very clear, and the boys brought up handfuls of glittering sand from the bottom. When Mr. Brewster saw it, he commented: "There's a fortune in gold to be dredged from this stream. But we still have the problem of getting it down the Orinoco."

Joe Nara had the answer to that problem. His Indians showed up with a small flotilla of odd-looking craft that resembled the monterias of the Amazon. Nearly thirty feet long, each boat had an open c.o.c.kpit at the front with a thatched cupola at the stern, serving as a sort of cabin.

Nara's boats were different, however, from the more antiquated river craft. His boats were low in the stern, so that the big steering paddle could be replaced by a sizable outboard motor. Nara had such motors and the gasoline to fuel them.

"Every trip I made downriver," explained Nara, "either over the mountain and down the Rio Negro, or down this stream to the Orinoco, I bought motors and gasoline and brought them back here. I knew that some day, Lew Kirby would talk some company into a big deal for our mine.

"What's more, I knew the first thing they would SURROUNDED! 141.

ask would be if they could transport either the gold or the ore once they mined it. My answer is, yes, and I've got the boats to prove it-and the motors, too. I've kept them for a long time."

Judging by the appearance of the motors, that was true. Some were twenty years old, but all proved serviceable when attached to the loaded boats. The four boats that formed the strange flotilla started out at a slow but steady speed down the narrow jungle river that marked the first stage of a long, adventurous journey.

Each boat carried a crew of three. Biff and Kamuka were in one boat with Mr. Brewster. Jacome and a Wai Wai Indian were in another with Hal Whitman. The third boat was Nara's, with Igo and Ubi as its crew. The fourth, which served as a kitchen boat and carried the food supply, was manned by three Wai Wai tribesmen.

The packs, which included tents and other equipment, were in the boats commanded by Mr. Brewster and Mr. Whitman. The ore from the mine was mostly in Nara's boat, which squatted lower in the water due to its added weight. But it maintained the same speed as the other craft for the simple but sufficient reason that Nara had equipped it with the largest of his old-model motors.

The containers of gasoline were distributed among the boats, and all were careful not to waste any of the precious fuel. At times, they used the oars or let the current carry them. When they encountered chan- 142 .
