Benita learned afterwards that they must have been placed there by the ancient Phoenicians, or whatever people constructed this gigantic fortification, and had something to do with the exact recordings of the different seasons of the year, and their sub-divisions, by means of the shadows which they cast.  As yet, however, she did not pay much attention to them, for she was engaged in considering a more remarkable relic of antiquity which stood upon the very verge of the precipice, the wall, indeed, being built up to its base on either side.

It was the great cone of which Richard Seymour had told her, fifty feet high or more, such as once was found in the Phoenician temples.  But in this case it was not built of masonry, but shaped by the hand of man out of a single gigantic granite monolith of the sort that are sometimes to be met with in Africa, that thousands or millions of years ago had been left standing thus when the softer rock around it was worn away by time and weather.  On the inner side of this cone were easy steps whereby it could be ascended, and its top, which might have been six feet in diameter, was fashioned in the shape of a cup, probably for the purposes of acts of worship and of sacrifice.  This extraordinary monument, which, except on the river side, could not be seen from below on account of the slope of the hill, leaned slightly outwards, so that a stone dropped from its crest would fall into the waters of the stream.

“Thence it was,” said the Molimo, “that my forefathers saw the last of the Portuguese, the fair daughter of the great Captain Ferreira, hurl herself to death after she had given the gold into our keeping, and laid the curse upon it, until she came again.  So in my dreams have I seen and heard her also, ay, and others have seen her, but these only from by the river far below.”

He paused awhile, looking at Benita with his queer, dreamy eyes; then said suddenly: 

“Say, Lady, do you remember nothing of that matter?”

Now Benita grew vexed, for the whole thing was uncanny and jarred upon her.

“How can I remember,” she asked, “who was born not five and twenty years ago?”

“I do not know,” he answered.  “How should I know, who am but an ignorant old black man, who was born not much more than eighty years ago?  Yet, Lady, tell me, for I seek your wisdom, where were you born from?  Out of the earth, or out of the heavens?  What?  You shake your head, you who do not remember?  Well, neither do I remember.  Yet it is true that all circles meet somewhere, and it is true that the Portuguese maiden said she would come again; and lastly it is true that she was such an one as you are, for she haunts this place, and I, who have seen her sitting yonder in the moonlight, know her beauty well.  Yet mayhap she comes no more in flesh, but still her spirit comes; for, Lady, out of those eyes of yours I see it gaze at me.  Come,” he added abruptly, “let us descend the wall, for as you cannot remember, there is more to show you.  Have no fear—­the steps are easy.”
