In the general introductory summary of the first report of the surveyors, the prospects of the tin fields of Northern Nigeria are described with the customary official reserve. “Tin, in the form of cassiterite,” the report stated, “has now been found in the stream beds of other districts. It is probable that as soon as suitable transport is provided Northern Nigeria will become an important tin-producing country. Already deposits in the Bauchi Province are being worked by the Niger Company, and the metal smelted on the spot. The first consignment of tin from the Protectorate has reached this country.” The prospect presented by this information, backed up by substantial shipments of tin, might have been expected to stimulate the curiosity of both prospectors and capitalists, and that other Richmonds would have made an appearance in the Bauchi field. But any hopes of such a result were doomed to disappointment. The Niger Company continued to win mineral, and the Mineral Survey persisted in their efforts to prove the extent of country over which the granites were tin bearing. It is possible that the remoteness and inaccessibility of the Protectorate operated unfavourably in the minds of mining adventurers, and the evil reputation which had been erroneously given to the country may have moved financiers to an excess of cautiousness. The colony made no new friends, and, as will be shown later, it was not until last year and then only by the accident of failure in another direction, that capital was diverted into the new tin field. TINSTONE CONCENTRATES ANALYSED Eleven specimens of tinstone concentrates from the Zagi River, south of Bauchi, from Bula, Tilde, and the river beyond Joss were forwarded to the Imperial Institute, and with only one exception were found upon analysis to contain tin in quantities of from mere traces up to 80.85 per cent, of tin oxide, equivalent to 63.5 per cent. of metallic tin in the concentrate. The official general remarks on the specimens analysed were as follows:
