“All right,” grinned Ted. “If I’m an ich––”
“Ich-thy-o-saur-us?” Radcliffe came to his rescue.
“Then you’re a dinosaur,” grinned Ted.
“Here, here, stop calling each other names!” commanded Radcliffe. “And perhaps Ace will tell us about this gypsum formation.”
“Thunder! Wish Norris was here! I tell you I’m no professor. But if you’re after fossils, don’t you remember what he told us, that day just before we lost the pack burro?—That in this part of California we have rock from the Cambrian era a mile thick, and I’ll bet it’s full of fossils of the fish age!”
“Well,” Radcliffe briskly interposed, as they came to another turn, “we’ll never find those Mexicans unless we separate and hunt faster than we’ve been doing. Are you fellows game for taking one way while I go back to that last turn and try the left hand passageway? Of course the instant you get wind of them, report back to me.” They signified their gameness by picking a precarious footing, (Ted first), along the slippery floor, their candles thrust in their hat bands.
Above they came to another but a smaller forest of alabaster stalactites, shining like icicles or mosses, some white as snow, some yellow as gold, and some so like maple sugar in appearance that Ace actually tasted it. In one place there was a bit of what Ace said was needle gypsum, that hung as fine as fur.
Radcliffe, retracing his steps, (with the aid of the twine ball), till he came to the cross roads, as it were, turned to the left and forged ahead with his carbide lamp, treading softly as a cougar, with revolver cocked in his right hand. Ever and anon he stopped breath-still to listen.
Passing through the same alabaster cavern that had so impressed the Spanish boy, his eye caught the bandanna Pedro had dropped in the left-hand passageway. With an inward exclamation, he hurried on till he had reached the end of the blind. Stooping with his lamp, he could see the fresh scratches their feet had made. Darting back to the turn of the tunnel, where he had picked up the bandanna, he took the only choice left to him, the right hand way, with all the satisfaction of a hound on the scent. More scratches on the sandstone floor assured him that they had really gone this way, instead of turning back the way they had come, and presently he too was standing in the gallery of the sloping floor and yellowed pillars, at whose far end the dripstone cataract hung, turned to soundless stone. But of the three Mexicans and Pedro there was no trace.
“I say, when do we eat?” Ace was just beginning, when the floor suddenly gave way beneath him, and he fell down a ten foot well, landing on all fours, in Stygian blackness. And no sooner had his bulk padded the stone beneath than Ted came, plunk! almost on top of him.
