smaller streams, we may 

 take the ease of the Ka- 

 ramba River, which joins 

 the Zambezi on its north- 

 ern bank, 35 miles east of 

 the Falls, and reproduces 

 neatly in miniature some 

 of the principal character- 

 istics of the great canon. 

 This stream has carved out 

 a wild gorge some 5 miles 

 in length, into which it 

 drops from an open valley 

 on the plateau (see plan, 

 fig. 6). The sides of this 

 gorge at the mouth of the 

 river, where they are 500 

 to 600 feet high, form bold 

 rocky slopes rising at an 

 angle of 30° to 40° from 

 the stream-bed ; then they 

 become gradually more 

 precipitous as we proceed up into the sharp loops above the 

 first straight reach ; their crests approach nearer and nearer to 



The dry-season water- 

 gully is 20 feet deep 

 at the line of section, 

 but sinks to 50 or 60 

 feetfarther eastward.
