Looking out through the open door at the back of the house, which could be seen from the hall, we beheld a small, flickering spark of fire, well up on the lower slopes of the mountain, which, even as we gazed, waxed in size and brilliancy.  Snatching up a powerful telescope that always hung ready to hand in the hall, and bringing it to bear upon the spark, I was able to make out that it was indeed a large house, from the windows and thatched roof of which flames were bursting in momentarily increasing volumes, while round about it a crowd of negroes were apparently dancing a dance of savage delight at the destruction which they were effecting.
