The lore of Frio was as romantic as its appearance, and worthy of the pen of Stevenson. Not only have traces come to light on a neighbouring promontory of Indian burials consisting of bones and pottery, but more valuable treasure finds were of not infrequent occurrence; buried Spanish coins turned up at intervals, and an ingot of silver had lately been discovered. There was no doubt, in the opinion of the storekeeper, that considerable treasure was hidden among the islands along the coast, but hunting for it was forbidden by the government. Not far from the village itself there was a cave, which was obviously the work of man, and said to connect two coves, but no one dared to explore it. Nothing was known of its history, but, according to tradition, it was the work of the Jesuits: why a religious order should have made such a resort our informant was unable to explain, but he evidently considered that it would be quite in accord with their usual underground and mysterious methods of procedure. Thirty years ago he himself, with the owner of the cave and one other, had taken up a barrel of wine and had a drinking bout at its entrance, a scene which some old painter of the Dutch school would surely have found congenial: he had then penetrated some twenty or thirty yards into the interior; it was at first, he said, narrow, then became wider, but since that time no one had entered it. S. was naturally fired with a desire to explore this hidden cavern; Mr. Gillam responded to the call for an assistant, and they set out for the place, accompanied by our informant. There proved to be some difficulty in discovering it, even with his assistance, owing to the dense vegetation which had arisen since it was last visited. Mr. Gillam’s thoughts not unnaturally turned to snakes, and the information given in reply to a question on the subject lacked something in reassurance: there were a great many about, it was said, and of a dangerous kind, but they only struck when trodden upon, and as it was now getting late in the day it might be hoped that they had retired to their lairs. When the cave was at length found, bushes and undergrowth had to be cut down in order to effect an entrance, and a cloud of bats flew out of the darkness within. The walls were examined by the light of a ship’s signalling lantern, and the statement that they had been artificially made was proved to be true. The party proceeded for ten or twelve yards, but then found that the way had been blocked by a comparatively recent fall of débris, and the enterprise had therefore to be abandoned. We commend it to fellow-voyagers and anthropologists.
