 with steep escarpments on all sides, except to the north, where 

 the descent to the Afram plains is in comparison rather gradual. 

 The climate of these hills is delightfully bracing, and from the 

 higher peaks magnificent views of the vast undulating plains to 

 the north can be obtained.

 Ahurum Eivers. It is a prominent range, having an average 

 altitude of about 1,800 feet.

 reach an altitude of close on 2,000 feet.

 steep, isolated hills, situated to the north-east of Aburi, in the 

 neighbourhood of Akuse.
