"Look here," Dominique said, taking three dollars from his pocket. "I will leave these with your father, and will hand you the other two as soon as we get within sight of the place where they are." The lad was quite satisfied. Five dollars was more than he could earn by two months' work. As soon as they went out, Dominique whispered to one of the boatmen to go back and tell Frank what had taken place, and to beg him to follow at some distance behind. Whenever they took a fresh turning, one of the boatmen would always be left until he came up. Frank had some difficulty in understanding the boatman's French, and it was rather by his gestures than his words that he gathered his meaning. As soon as the message was given the negro hurried on until he overtook Dominique. "I am sorry now that we did not bring Pedro," Frank said. "However, I think we made out what he had to say. Dominique has got someone to go with him to do the questioning, as he arranged with me; and he will leave one or other of the men every time he turns off from the road he is following. That will be a very good arrangement. So far we have been most fortunate. We know now that we are following them, and it will be hard if we don't manage to keep the clue now that we have once got hold of it." When they came to the road that branched off to the right, the other boatman was waiting. He pointed up the road and then ran on silently ahead. No fresh turn was made for a long distance. Twice they were stopped by one of the blacks, who managed to inform them that Dominique and the guide were making inquiries at a hut ahead. The road had now become a mere track, and was continually mounting. Other tracks had branched off, leading, Frank supposed, to small hill villages. After going some ten miles, the lad told Dominique that it was useless for him to go further, for that there were no more huts near the track. Beyond the fact that the two women were on horseback when they passed the last hut, nothing was learned there. "It is of no use to go further," the guide said. "There are no houses near here to inquire at, and there are three or four more paths that turn off from here. We must stop until morning, and then I will go on alone and make inquiries of shepherds and cottagers; but, you see, I thought that we should find them tonight. If I work all day tomorrow, I shall expect three more dollars." "You shall have them," Dominique said. "Here is my blanket. I will share one with one of my boatmen." The lad at once lay down and pulled the blanket over his head. As soon as he did so, Dominique motioned to the two boatmen to do the same, and then went back along the track until he met Frank's party. As the hills were for the most part covered with trees almost up to their summits, Frank and his party had only to turn a short distance off from the path, on receiving Dominique's news that the guide had stopped.
