Chap. Vlll. AERIVAL IN OTANDO-LAND. 155 



not to spend another night in the solitude of the 

 forest. 



Nothing occurred worthy of mention during the 

 remainder of our march except the crossing of a deep 

 river, another of the tributaries of the Ngouyai, about 

 ten miles west of Mayolo. This stream is called the 

 Oganga, and for me it was a new discovery, as I did 

 not see it on my journey to the Apingi country in 

 1858. It is a deep river at all seasons of the year. 

 We traversed it by a bridge, formed of the trunk of 

 a colossal tree which lay across it. We were delayed 

 a short time on the banks of the stream by the men 

 stopping to gather and eat Koola nuts, vast quanti- 

 ties of which lay beneath a group of trees of this 

 species that grew here. We were approaching the 

 end of our journey, and the blue sky began to 

 appear through the breaks in the crowns of the trees 

 ahead.
