I could see Terry’s jaw set at that. No place for men? Dangerous? He looked as if he might shin up the waterfall on the spot. But the guide would not hear of going up, even if there had been any possible method of scaling that sheer cliff, and we had to get back to our party before night. “They might stay if we told them,” I suggested. But Terry stopped in his tracks. “Look here, fellows,” he said. “This is our find. Let’s not tell those cocky old professors. Let’s go on home with ’em, and then come back--just us--have a little expedition of our own.” We looked at him, much impressed. There was something attractive to a bunch of unattached young men in finding an undiscovered country of a strictly Amazonian nature. Of course we didn’t believe the story--but yet! “There is no such cloth made by any of these local tribes,” I announced, examining those rags with great care. “Somewhere up yonder they spin and weave and dye--as well as we do.” “That would mean a considerable civilization, Van. There couldn’t be such a place--and not known about.” “Oh, well, I don’t know. What’s that old republic up in the Pyrenees somewhere--Andorra? Precious few people know anything about that, and it’s been minding its own business for a thousand years. Then there’s Montenegro--splendid little state--you could lose a dozen Montenegroes up and down these great ranges.” We discussed it hotly all the way back to camp. We discussed it with care and privacy on the voyage home. We discussed it after that, still only among ourselves, while Terry was making his arrangements. He was hot about it. Lucky he had so much money--we might have had to beg and advertise for years to start the thing, and then it would have been a matter of public amusement--just sport for the papers. But T. O. Nicholson could fix up his big steam yacht, load his specially-made big motorboat aboard, and tuck in a “dissembled” biplane without any more notice than a snip in the society column. We had provisions and preventives and all manner of supplies. His previous experience stood him in good stead there. It was a very complete little outfit. We were to leave the yacht at the nearest safe port and go up that endless river in our motorboat, just the three of us and a pilot; then drop the pilot when we got to that last stopping place of the previous party, and hunt up that clear water stream ourselves. The motorboat we were going to leave at anchor in that wide shallow lake. It had a special covering of fitted armor, thin but strong, shut up like a clamshell. “Those natives can’t get into it, or hurt it, or move it,” Terry explained proudly. “We’ll start our flier from the lake and leave the boat as a base to come back to.” “If we come back,” I suggested cheerfully. “‘Fraid the ladies will eat you?” he scoffed. “We’re not so sure about those ladies, you know,” drawled Jeff. “There may be a contingent of gentlemen with poisoned arrows or something.”
