"Yes, yes, Mr. Dick, only too well I know it. We are in Africa!"
The old man sighed mournfully.
"Tom," said Dick, in the same low voice, "you must keep this a secret; you must not say a word to let Mrs. Weldon or any of the others know "
The old man murmured his assent, and Dick continued:-
"It will be quite enough for them to learn that we have been betrayed by Harris, and that we must consequently practise extra care and watchfulness; they will merely think we are taking precautions against being surprised by nomad Indians. I trust to your good sense, Tom, to assist me in this."
"You may depend upon me, Mr. Dick; and I can promise you that we will all do our best to prove our courage, and to show our devotion to your service."

Thus assured of Tom's co-operation, Dick proceeded to deliberate upon his future line of action. He had every reason to believe that the treacherous American, startled by the traces of the slaves and the unexpected roaring of the lion, had taken flight before he had conducted his victims to the spot where they were to be attacked, and that consequently some hours might elapse before he would be joined by Negoro, who (to judge from Dingo's strange behaviour) had undoubtedly for the last few days been somewhere on their track.
Here was a delay that might be turned to good account, and no time was to be lost in taking advantage of it to commence their return journey to the coast. If, as Dick had every reason to suppose, he was in Angola, he hoped to find, either north or south, some Portuguese settlement whence he could obtain the means of transporting his party to their several homes.
But how was this return journey to be accomplished? It would be difficult, not to say imprudent, to retrace their footsteps through the forest; it would merely bring them to their starting-point, and would, moreover, afford an easy track for Negoro or his accomplices to follow. The safest and most secret means of reaching the coast would assuredly be by descending the course of some river. This would have to be effected by constructing a strong raft, from which the little party, well armed, might defend themselves alike from attacks either of the natives or of wild beasts, and which would likewise afford a comfortable means of transport for Mrs. Weldon and her little boy, who were now deprived of the use of Harris's horse. The negroes, it is true, would be only too pleased to carry the lady on a litter of branches, but this would be to occupy the services of two out of five, and under the circumstances it was manifestly advisable that all hands should be free to act on the defensive. Another great inducement towards the plan was that Dick Sands felt himself much more at home in travelling by water than by land, and was longing to be once again upon what to him was, as it were, his native element. He little dreamt that he was devising for himself the very plan that Harris, in his speculations, had laid down for him!
