They had struck a cave. Early in the boring the sandstone had given place to a vein of Comanchian limestone full of minute fossil cephalopods, corals, echini, and spirifera, and with occasional suggestions of siliceous sponges and marine vertebrate bones—the latter probably of teliosts, sharks, and ganoids. This in itself was important enough, as affording the first vertebrate fossils the expedition had yet secured; but when shortly afterward the drill-head dropped through the stratum into Apparent vacancy, a wholly new and doubly intense wave of excitement spread among the excavators. A good-sized blast had laid open the subterrene secret; and now, through a jagged aperture perhaps five feet across and three feet thick, there yawned before the avid searchers a section of shallow limestone hollowing worn more than fifty million years ago by the trickling ground waters of a bygone tropic world.
The hollowed layer was not more than seven or eight feet deep, but extended off indefinitely in all directions and had a fresh, slightly moving air which suggested its membership in an extensive subterranean system. Its roof and floor were abundantly equipped with large stalactites and stalagmites, some of which met in columnar form; but important above all else was the vast deposit of shells and bones which in places nearly choked the passage. Washed down from unknown jungles of Mesozoic tree-ferns and fungi, and forests of Tertiary cycads, fan-palms, and primitive angiosperms, this osseous medley contained representatives of more Cretaceous, Eocene, and other animal species than the greatest palaeontologist could have counted or classified in a year. Molluscs, crustacean armour, fishes, amphibians, reptiles, birds, and early mammals—great and small, known and unknown. No wonder Gedney ran back to the camp shouting, and no wonder everyone else dropped work and rushed headlong through the biting cold to where the tall derrick marked a new-found gateway to secrets of inner earth and vanished aeons.
