II. — An Enquiry into the Origin of certam Terraced Sloi^es in 

 North Tynedale. By the Rev. G. Rome Hall. 



The subject of our present enquiry is one of considerable inter- 

 est, and, at the same time, of no little difficulty. What may 

 have been the origin "of those remarkable terrace-lines which 

 occasionally appear on the declivities of our upland valleys or 

 lower river-basins, forms a problem which cannot as yet be said 

 to be positively and satisfactorily solved. Different observers — 

 the geologist, the military engineer, the practical agriculturalist, 

 and the archaeologist, have reviewed them from their own par- 

 ticular stand-point, and, as might be expected, have traced their 

 formation to various and widely different agencies.
