In all places, and at all times, gold, probably the metal first used by man, has been worked in the same way. This is a fair evidence of that instinctive faculty which produces a general resemblance of rude stone-implements from England to Australia. There are six methods for 'getting' the precious metal--surfacing or washing; shallow-sinking; sluicing, or removing the earth through natural and artificial channels; deep sinking; tunnelling, and quartz-mining. The preceding notes show that the natives of the Gold Coast, and of West Africa generally, are adepts at procuring their gold by 'surfacing,' washing with the calabash or wooden bowl the rich alluvial formations that underlie the top-soil. This is the rudest form of machinery, preceding in California the cradle, the torn, and the sluice. Westerns made their pans of brass or copper, about sixteen inches in diameter, and nearly two inches deep in the middle where the gold gravitates. Panning in Africa is women's work, and the process has been described in the preceding pages. But the natives, as has been shown, can also work quartz, an art well known to the Ancient Egyptians. They either pick up detached pieces showing visible gold, or they sink pits and nibble at the walls of the reefs. But whereas the Nile-peoples pounded the stone in mortars and washed the dust on sloping boards, here the matrix must be laboriously levigated. A handful of broken quartz is placed upon the 'cankey-stone,' with which the gudewife grinds her 'mealies.' It is a slightly hollowed slab of granite or hard conglomerate, some two feet square, sloping away from the worker, and standing upon a rude tripod of tree-branches secured by a lashing of 'tie-tie.' The stuff is then rubbed with a hand-stone not unlike a baker's roll, and a slight deviation is given to it as it moves 'fore and aft.' The reduced stone is caught in a calabash placed at the lower end of the slab. This is usually night-work, and all the dark hours will be wasted in grinding down a cubic foot of stone.
