EXPLOEATION OF THE KIBALI 329 



wax, some of which weighed no less than ten pounds ; but 

 substantial as they were, they never lasted more than two 

 days and sometimes not even that, having to be renewed at 

 the end of each day's journey. There was always a certain 

 amount of leakage going on, and I shall never forget the 

 anxiety with which I used to watch the water creeping inch 

 by inch above the floor-boards. Quasso sat in the stern

 soldiers, mimicking the noise they made as they ran before

 the south, and the country on both sides becomes very open, 

 with nothing but long grass intersected by numberless 

 elephant-paths. In places the banks are quite flat with low,
