A further use which we immediately made of our increased powers of production was to put up two new saw-mills and a brewery. The saw-mills were needed to supply material for the shelter of the continually increasing stream of fresh arrivals; and the brewery was intended to serve as a means of agreeably surprising the new-comers with a welcome draught of a familiar beverage with which most of them would be sorry to dispense. As soon as the barley was cut and threshed, it was malted. Our gardeners had grown hops of very acceptable quality on the sides of the Kenia foot-hills; and soon a cool cellar, made by utilising some natural caverns, was filled with casks of the noble drink. By the end of October we were able to contemplate our four months' labours with a restful satisfaction. Six hundred neat block-houses awaited as many families; 50,000 cwt. of corn and flour, copious supplies of cattle for slaughter and draught, building material and tools, were ready for the food, shelter, and equipment of many thousands of members. The garden had been not less successfully cultivated, and its dainty gifts were already beginning to be enjoyed. Our own garden-produce did not, as yet, suffice to cover our anticipated requirements; but it continued to be supplemented by a brisk barter trade with the Wa-Kikuyu. For these natives we had established a regular weekly market in Eden Vale, which several hundreds of them attended, bringing with them their goods upon ox-carts, the use of which we had introduced among them and had made possible by means of the roads our engineers had constructed through their country. Since we had set up our iron-works, the Wa-Kikuyu came to us principally for iron either in a raw condition or made up into tools. For this they at first bartered cattle and vegetables; afterwards, when we no longer needed these things, they offered mainly ivory, of which we had already acquired 138 tons, partly through our trade with the Wa-Kikuyu and the Andorobbo, and partly as the fruits of our own hunting. For ivory is as cheap here as blackberries; the Wa-Kikuyu and the Andorobbo are glad to buy our wrought iron for double its weight in the material which is so valuable in the West. An iron implement, whether hammer, nail, or knife, is exchanged for from ten to twenty times its weight in ivory. Thus almost the whole cost of our expedition was already covered by our ivory--the cattle and provisions, the implements and machinery, not to speak of the land, being thrown in gratis. CHAPTER VI Whilst we at the Kenia were thus busily preparing a comfortable home for our brethren who were expected from the Old World, our colleagues, under the direction of Demestre and Johnston, were working not less successfully on the tasks allotted to them.
