The construction of the flour-mill demanded a greater expenditure of labour. The mill was fixed on the upper course of the Dana, 1,100 yards above the entrance of the river into the Eden lake, and was furnished with ten complete sets of machinery. The site was chosen because just above there was a strong rapid, while below the Dana flowed calmly with a very trifling fall until it reached the great cataract. Thus we had, through the whole of the provisionally occupied district, a splendid waterway to the mill, and yet for the mill we could take advantage of the rapid flow of the upper Dana. We had brought from Europe the more complicated and delicate parts of this mill; but the wheels, shafts, and the ten millstones we manufactured ourselves. This mill--which was provisionally constructed of wood only--was ready by the end of September, thanks to the additional assistance of the two instalments of members which had reached us in the early part of the same month. I have already mentioned that, as soon as we had reached the Kenia, I asked our committee for fresh supplies and a fresh body of pioneers; and that the committee had informed me that at the end of July there would start an expedition of 260 horsemen and 800 cwt. of goods upon 300 beasts. This expedition reached Mombasa on the 18th of August. Then it divided into two groups: one group, containing the most adventurous 145 horsemen, started at once on the 18th of August with fifty very lightly loaded led-horses--the whole of the 300 sumpter beasts were horses--without taking with them a single native except an interpreter. They relied upon the assistance of those of our men who were constructing the roads, and of the population friendly to us; but they were at the same time resolved to bear without murmuring any deprivations and fatigue that might await them. A forced ride of twenty days, with only a one day's rest at Taveta, brought these brave fellows among us on the 9th of September. Five horses had died, seven others had to be left behind knocked up; they themselves, however, all reached us, except one who had broken his leg in a fall, and was left in good hands in Miveruni, somewhat exhausted, but otherwise in good condition. The newly arrived joined us heartily in our work two days after. The 115 others reached us ten days later, with 250 sumpter horses and 100 Swahili drivers. The greater part of the goods they had given to Johnston on the way, who met with them at Useri, where he had been eagerly awaiting them. The articles brought to us at the Kenia--in all something over 300 cwt.--contained a quantity of tools and machinery; these, and especially the considerable addition of workmen, contributed in no small degree to expedite our various works.
