Let us now give some particulars concerning the cantons themselves: the first gulf[5] found in the province of Caizcimu cuts into a rock where it has worn an immense cave situated at the foot of a lofty mountain about two stadia from the sea. Its vast arched entrance resembles the gates of a great temple. In obedience to an order from the government, Morales tried to enter this cavern with the ships. Several streams come together there through unknown channels, as in a drain. It used to be a mystery what became of a number of rivers ninety miles long, which suddenly disappeared under the earth never to be seen again. It is thought they are in some fashion swallowed up in the depths of the rocky mountain, continuing their underground course till they reach this cavern. Having succeeded in entering the cave, Morales was very nearly drowned. He reports that inside there are whirlpools and currents in incessant conflict, upon which his barque was tossed to and fro like a ball, amidst the horrible roar of the whirlpools and currents around him. He regretted having come, but could find no way to get out. He and his companions drifted about in the obscurity, not only because of the darkness prevailing in the cavern, which extends into the depths of the mountains, but also because of the perpetual mist rising from the constantly agitated waters, and resolving itself into damp vapours. Morales compared the noise of these waters to that of the falls of the Nile where it pours forth from the mountains of Ethiopia. Both he and his companions were so deafened they could not hear one another speak. He finally succeeded in finding the exit, and emerged from the cavern, trembling, feeling that he had left the infernal regions and returned to the upper world.[6] [Note 5: The gulf of Samana; its extent is 1300 square kilometres.] [Note 6: _Evasit tandem pavidus de antro, veluti de Tartaro, putans rediisse ad superos_.]
