The ground which fronts the reef-ford reflects that of the left bank, and is pitted with diggings, large and small. In a dry torrent-bed, running north-south, was an oblong shaft, a native copy of European work, four feet by six, and timbered in the usual negro way. Its further bank was a high and steep slope of yellow clay with a midway step, containing another and a similar shaft: to the north and west were many other signs of exploitation. The rich-looking quartz of the lode is white and sugary, with black streaks and veins: its strike is nearly meridional, between north 20º and 25º east, and the dip 40º-45º east. A glance shows that _Fluthwerk_ and 'hydraulicking' would easily wash down the whole alluvial and auriferous formation to the floor of grey granite which has supplied the huge 'cankey-stones' [Footnote: This proto-historic implement, also called a 'saddle-quern,' is here made out of a thick slab of granite slightly concave and artificially roughened. The muller, or mealing-stone, is a large, heavy, and oval rolling-pin used with the normal rocking and grinding motion. These rollers are also used for crushing ore, and correspond with the stone _polissoirs_ of ancient date.] littering the village. Cameron, who had before visited the site, and had remarked how vigorously the placer-gravels had been attacked by the natives, would 'hydraulick' by means of the St. John's River. This might also be done by damming up and tapping the adjacent bottom. And, if routine work be wanted, it would cost little to construct upon the topmost crest a large reservoir with channels to conduct the rains, and thus secure a fair fall for the water.
