The three iron-framed stamp-boxes discharge their sludge into two parallel mercury- or amalgam-boxes, which Mr. Appleby declares will arrest 75 to 80 per cent. of free gold. It then passes on to the distributing table, the flow to the strakes being regulated by small sluices. Of the latter there is one to each width of green baize or of mining-cloth made for the purpose. The overflow of the sluices runs into a large tailing-tank of board-work, with holes and plugs at different levels to tap the contents. These tailings are also washed by women. Finally, the mercury is squeezed through leathers and the hard amalgam is sent for treatment to England. Retorting is not practised at present in any of the mines. The only reduction-gear belongs to the Gold Coast Mining Company; and some time must elapse before it is ready for use. My discovery of native cinnabar will then prove valuable. The Effuenta can now bring to bank, with sufficient hands, at least a hundred tons a day of good paying ore; whereas the stamps can crush at most one-tenth. When this section of the lode, about 200 fathoms, shall be worked, there will still be the balance of 1,000. But even this fifth of the property will supply material for years. The proportion of gold greatly varies, and I should not like to hazard a conjecture as to average, but an ounce and a half or two ounces will not be above the mark. At present the manager works under the difficulty of wanting European assistants. His mining-engineer and one mechanic lately left him to return home; and he has only a white book-keeper, an English working-miner, and a mechanic, besides a man who made his way from the coast on foot, and who is now doing good, honest work. The progress made by Mr. MacLennan, during his ten months of charge, has been most creditable. He has literally opened the mine, the works of which were begun by M. Dahse. He has personally supervised the transport and erection of all the machinery; and at present, in addition to the ordinary managerial routine, he has to act as chief of each and every department. Owing to his brave exertions the future of the Effuenta mine is very promising: it will teach those to come 'how to do it,' in contrast with another establishment which is the best guide 'how _not_ to do it.' If the Board prove itself efficient, this property will soon pay a dividend. But half-hearted measures will go far to stultify the able and energetic work I found on the spot. [Footnote: This forecast has been unexpectedly verified with the least possible delay. Perfect communication has been established between the shafts and levels; and the mine can now (October 1882) turn out 100 tons a day at five shillings. But imperfect pumps have been sent out, and the result is a highly regretable block. Of the value of the mine there can be no doubt.]
