Saying this, Costal bent towards his companion; and with the blade of his knife commenced opening a hole in the keel of the canoe. In the worm-eaten wood this might be easily effected; and, working with all the _sang-froid_ of a wood-carver, in a few seconds Costal succeeded in making an aperture large enough to admit the hand. Through this Lantejas thrust his fingers; and, clutching firmly underneath, was now in a condition to maintain his seat against the waves that were threatening every moment to roll over the spot. Costal, having thus secured his companion, and provided for his own safety in a similar fashion, now commenced peering through the darkness in hopes of seeing the barges. In this he was disappointed. Though the lightning now flashed at shorter intervals, its gleams revealed only the dark and scowling water, the isle sleeping in sullen gloom, and farther off the frowning mass of the fortress-crowned cliff. Notwithstanding that the castaways now shouted at the highest pitch of their voices, there was no response from the whale-boats. Their cries pealed along the seething surface of the waters, and died without even an echo. CHAPTER THIRTY FIVE. FEARFUL FELLOW-SWIMMERS. The shipwrecked sailor, floating upon his frail raft, or some spar of his shattered vessel, could not be more at the mercy of wave and wind, than were the two men astride of the capsized canoe. Their situation was indeed desperate. The stroke of a strong sea would be sufficient to swamp their frail embarkation; and, should the tempest continue to increase in fury, then destruction appeared inevitable. Despite the imminent danger, Lantejas still indulged a hope that the intrepidity of the Zapoteque might rescue him from the present danger, as it had from many others. Sustained by this vague belief, he kept his eyes fixed upon the countenance of Costal, while endeavouring to read in its expression the condition of the Indian's spirit. Up to that time the imperturbable coolness exhibited by the _ex-tigrero_ had favoured the hopes of his companion. As the time passed, however, and nothing was seen of the whale-boats, even the features of Costal began to wear an expression of anxiety. There is a difference, however, between anxiety and despair. The spirit of the Indian had only succumbed to the former of these two phases. "Well, Costal, what think you?" demanded Lantejas, with a view of breaking the silence, which appeared to him of ill omen. "_Por Dios_!" replied the Indian, "I'm astonished that the barges have not moved up on hearing that shot. It's not like the Marshal to hang back so. He don't often need two such signals to advance--"
