A path from Indemau was discovered, leading across the Dui River; there was another leading to Indeperri, a large settlement about fifteen miles N.E. from Fort Bodo. It had been my original purpose to steer a course through the forest which would take us direct to the grass-land, along a more northerly route than the line of Ipoto and Fort Bodo, after sending a detachment to settle accounts with Kilonga-Longa; but in our endeavour to find a ford or ferry across the Ihuru we had been compelled by the high flood to continue parallel with the river until now. Observation proved us to be in N. lat. 1° 47′ and E. long. 29° 7′ 45″. But the discovery of Remington cartridges among the stores of a native caravan in these unknown parts, and yet within a reasonable distance of Fort Bodo, notwithstanding a rational assurance that Fort Bodo was impregnable and the garrison were now safe with Emin Pasha on the Nyanza, had intruded doubts in my mind which I thought would best be resolved by deflecting our course southward, and sweeping past the old Fort, and seeing with our own eyes what had really occurred. Mr. Bonny was therefore sent with the chief Rashid and sixty men, to build a bridge across the Dui River. [Sidenote: 1888. Dec. 1. Dui River.] After a halt of five days the Expedition marched from Indemau on the 1st of December for the Dui. Mr. Bonny and old Rashid, with their assistants, were putting the finishing touches to the bridge, a work which reflected great credit on all concerned in its construction, but especially on Mr. Bonny. Without halting an instant the column marched across the five branches of the Dui, over a length of rough but substantial woodwork, which measured in the aggregate eighty yards, without a single accident. [Illustration: BRIDGING THE DUI RIVER.] On the other side of the Dui we made a rough muster of the people, and discovered that thirty-four of the rear column had died, and that out of sixteen Zanzibaris on the sick list, fourteen were of the Yambuya party, and they all appeared to be in such a condition that a few days only would decide their fate. Every goat and fowl that we could procure were distributed to these poor people in the hope of saving them. We cooked for them; Mr. Bonny was directed to administer medicines daily; we relieved them of every article, excepting their own rations, and yet so wrecked were their systems by what they had endured at Yambuya and Banalya, that a slight abrasion from plants, branches or creepers, developed into a raging ulcer, which in three or four days would be several inches across. Nothing but the comforts and rest obtained in a metropolitan hospital would have arrested this rapid decline.
