Dingo was no longer there to scent the Portuguese, to announce his approach. Hercules alone might come to the assistance of the unfortunate Mrs. Weldon. But was that miracle to be hoped for?
However, Dick Sand fell back again on that idea. He said to himself that the strong black man was free. Of his devotion there was no doubt. All that a human being could do, Hercules would do in Mrs. Weldon's interest. Yes, either Hercules would try to find them and put himself in communication with them; or if that failed him, he would endeavor to concert with him, Dick Sand, and perhaps carry him off, deliver him by force. During the night halts, mingling with these prisoners, black like them, could he not deceive the soldier's vigilance, reach him, break his bonds, and lead him away into the forest? And both of them, then free, what would they not do for Mrs. Weldon's safety. A water course would enable them to descend to the coast. Dick Sand would again take up that plan so unfortunately prevented by the natives' attack, with new chances of success and a greater knowledge of the difficulties.
The young novice thus alternated between fear and hope. In fact, he resisted despair, thanks to his energetic nature, and held himself in readiness to profit by the least chance that might offer itself to him.
What he most desired to know was to what market the agents were taking the convoy of slaves. Was it to one of the factories of Angola, and would it be an affair of a few halting-places only, or would this convoy travel for hundreds of miles still, across Central Africa? The principal market of the contractors is that of N'yangwe, in Manyema, on that meridian which divides the African continent into two almost equal parts, there where extends the country of the great lakes, that Livingstone was then traversing. But it was far from the camp on the Coanza to that village. Months of travel would not suffice to reach it.
That was one of Dick Sand's most serious thoughts; for, once at N'yangwe, in case even Mrs. Weldon, Hercules, the other blacks and he should succeed in escaping, how difficult it would be, not to say impossible, to return to the seacoast, in the midst of the dangers of such a long route.
But Dick Sand soon had reason to think that the convoy would soon reach its destination. Though he did not understand the language employed by the chiefs of the caravan, sometimes Arab, sometimes the African idiom, he remarked that the name of an important market of that region was often pronounced. It was the name Kazounde, and he knew that a very great trade in slaves was carried on there. He was then naturally led to believe that there the fate of the prisoners would be decided, whether for the profit of the king of that district or for the benefit of some rich trader of the country. We know that he was not mistaken.
Now, Dick Sand, being posted in the facts of modern geography, knew very exactly what is known of Kazounde. The distance from Saint Paul de Loanda to this city does not exceed four hundred miles, and consequently two hundred and fifty miles, at the most, separates it from the camp established on the Coanza. Dick Sand made his calculation approximately, taking the distance traveled by the little troop under Harris's lead as the base. Now, under ordinary circumstances, this journey would only require from ten to twelve days. Doubling that time for the needs of a caravan already exhausted by a long route, Dick Sand might estimate the length of the journey from the Coanza to Kazounde at three weeks.
Dick Sand wished very much to impart what he believed he knew to Tom and his companions. It would be a kind of consolation for them to be assured that they were not being led to the center of Africa, into those fatal countries which they could not hope to leave. Now, a few words uttered in passing would be sufficient to enlighten them. Would he succeed in saying those words?
Tom and Bat--chance had reunited the father and son--Acteon and Austin, forked two by two, were at the right extremity of the camp.
