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.
The late M. Bonnat had probably read Mr. Andrew Swanzy's evidence before the House of Commons in 1816: 'Gold is procured in every part of the country; it appears more like an impregnation of the soil than a mine.' His long captivity at Kumasi, where to a certain extent he learned the Oji speech, familiarised him with the native processes; and thus a Frenchman taught Englishmen to work gold in a golden land where they have been domiciled--true _fainéants_--for nearly three centuries. He came out in the Dries of 1877 with the intention of dredging the Ancobra River where the natives dive for the precious metal. He was working in western Apinto, a province of Wásá, under Kofi Blay, a vassal of King Kwábina Angu, when he was visited (January 1878) by Major-General Wray, B.A., Colonel Lightfoot, and Mr. Hervey, who were curious to see the work. They remained only till the return of the mail-steamer, or about five weeks. The General left with some first-rate sketches; the Colonel caught a fever, which killed him at Madeira; and the Esquire, who bears a name well known in Australia, returned to the Gold Coast for the purpose of writing not unprofitable reports. M. Bonnat was presently informed of the Tákwá Ridge, mines well known for a century at least to Cape Coast Castle, and ever the principal source of the Axim currency. They were still worked in 1875 by the people who drew their stores from Axim. A five-weeks' residence convinced him that they were rich enough to attract capital; he went to Europe, and was successful in raising it. Thus began the Tákwá mines, where, by a kind of irony of Fate, the beginner was buried.
