what information did Infadoos give about the great witch hunt?

In quiet conference, the men agree that this must be the site of King Solomon’s diamond mine. Infadoos confirms this be relating how people of old came from distant lands to go to these mountains for something—he does not say what, but is satisfied to learn that Quatermain rightly asserts that it was to obtain shining stones. Infadoos explains that it is the Place of Death for the Kakuanas, where all their chiefs are buried upon death. In a mysterious turn, Umbopa also confirms that the diamonds are in the mines of the “Three Witches,” claiming that he dreamed it so it is true. He explains himself no further.
