This plan seemed the only one that could suggest itself to the two bold spirits. Harry Fenn’s retreat could not long be kept a secret, as he must have food taken to him, and every visit to the tree of refuge made the discovery either by dogs or men more probable. What Andreas did not reveal, however, to Carlo was that for him this expedition was almost sure to lead to harm. His absence was certain to be discovered or betrayed, even though he meant to arrange during his absence for the well-being of the cattle under his charge; and if discovered Andreas knew that his life would be taken. He had faced the question, and had accepted the danger, for his love for Carlo was stronger than any fear of death. Carlo explained what had been decided upon, and though Felipa and Catalina both cried at the idea of the separation, Doña Elena saw that this plan was the only one which gave her nephew a chance of safety. ’Ah, Andreas, God will reward you,’ she said, taking the Indian’s hand in hers; ’for we poor captives can but give you thanks.’ Etta, who had been listening to all this, now added anxiously: ’But, dear Carlo, suppose Andreas does not return, how can we ever find you or Harry?’ ’I will tell you, Señora,’ said Andreas. ’You are right to ask, for the island has no name for the white men, and I never myself knew of a ship that stopped there. Give me some paper.’ Taking the parchment-like pith, which was all the prisoners could procure to write on, Andreas roughly marked out with a thorn the position of the island with regard to its distance from St. Catherine, making clever indications to show where dangerous rocks were to be found, and on which side the island could be approached. ’Keep that by you, Señorita, and if you can get away in a big ship, the Captain will understand where to find the Señor Carlo.’ He then made his Indian salutation and departed, saying he had much to do before the next sunset, and that if all were well he would come and fetch the Señor Carlo the next evening; but, till then, he advised great care, for fear of discovery.
