“We know that there are considerable areas there which in some cases are very rich in alluvial tin. There are also tin lodes there; but that for the present is another story, because alluvial tin is a thing which is easily and comparatively inexpensively worked, whereas to work a lode mine requires good means of transport, and to be able to get up to the mines easily expensive and heavy machinery. We have a good climate, we have a sufficiency of water, and so far as we can ascertain, we have a sufficiency of native labour. All the companies which are interested in Northern Nigeria appear anxious to co-operate, and are willing to work together generally for their mutual benefit, and for the tin industry in particular.” Mr. H. W. Lake, the consulting engineer, speaking in a professional capacity at the same meeting, referred to the phenomenal richness of the river banks in the tin district in Northern Nigeria, while very rich alluvials are found on the flats, and when it comes to investigation of the river banks themselves very much larger quantities of black tin to the cubic yard are won. “I am speaking now,” he added, “from a certain amount of experience, because four years ago we had an expedition in the Bauchi district, and our engineer obtained some quite remarkable results from the alluvial. Of course, it is a new country. There is a great deal of pioneering work to be done, and what we have still to look forward to is steady systematic organisation for the next year or two. We do not want to make the mistakes that have been made in the opening up of many new countries—some of them not very far from Nigeria—but we do want to settle down to steady systematic development. As far as the railway is concerned, there seems no doubt that we shall have a line into the tin fields, which is going to simplify the question of transport, and reduce the costs very materially. With regard to the actual working of these alluvials, to begin with, I am of opinion that we should use the simplest methods possible—ground sluicing and so forth, but there will come a time when we shall have very seriously to consider the question of hydraulicing and treating these alluvials on a very much larger scale than would be possible by means of sluicing.” A DISTRICT FULL OF NARAGUTAS
