Four fountains rising so near to each other would readily be supposed to have one source, and half the water flowing into the Nile and the other half to the Zambesi, required but little imagination to originate, seeing the actual visitor would not feel bound to say how the division was effected.

He could only know the fact of waters rising at one spot, and separating to flow north and south.

The conical tops to the mound look like invention, as also do the names.
