running down a watercourse, then crossing to another. Bomero was the leader always, and he seemed to know the way quite well. We always camped at water, and when we crossed from one creek to another the distance was usually no more than three or four miles. We passed a good many hills, but none of them I should say rising more than a thousand feet from the plain, and few of them so much as that. As far as I could reckon we must have travelled twenty-five to thirty miles a day, and the greater part of that was westing. I believe that on the evening of the twelfth day after we fell in with Bomero's people we must have been all of three hundred or three hundred and fifty miles to the west of the telegraph wire.
During those twelve days we did our best to study the people and the country so as to prepare ourselves for anything that might happen. Jack made a rough chart of each day's march, and we both made an attempt to keep a sort of dead reckoning. It was very hard, however, to make any available record of our observations. The curiosity and perhaps the suspicion of the blacks made it next to impossible to write or draw by daylight, and at night we had only the light of our fires and a sort of torch that we managed to make of bark and fat.
