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.
We slept once more at Anima-kru; and here Cameron made sure of his
position by Jupiter and Procyon, and by his valuable watch-chronometer,
the gift of his brother-officers: it worked peculiarly well. The St.
John's mine lies in north lat. 4? 49' 44", and in west long. (G.) 2? 6'
44". While the owners would place it seven miles from the sea, it is
distant only 2.2 from 'old Fort Brandenburg.' Early next morning we packed
and prepared for return, the chief Mra Kwami insisting upon escorting us.
