the whole would become :i barren waste. The adhe- 

 siveness of the soil counteructs the uneveness of (he 

 suifact-, and is justly proportioned by the liund of" its 

 bountifid creatov, to the purposes of vei^etatioti. Tliis 

 region partakes somewhat of tlie qualities and appear* 

 ancc of the hilly country, and has lost all superlieiul tra- 

 ces of the alluvial. The rocks, which in the hilly reyioa 

 only shew their projective points, and can o))ly he par- 

 tially observed and remotely traced, time having- worn 

 and carried awa}' all the looser and ligiiter substances, 

 which compose a large portion of the surface of th" ale 

 luvial region, and the covering' of the rocks in the hilly 

 region, has here laid bare, and masses of lock stud the 

 whole face of this country The earth is also in many 

 places almost covered with its fiagments, which conunu. 

 nicate to the soil various qualities, and many tinics 

 great fertility. The lertility of the soil in this region 

 depends also greatly upon the fijrm of the surface, as is 

 easily conceived in so elevated and broken a couritry. 

 Vallies sulTiciently level ior all the pnrp<jscs ol cultiva- 

 tion, and of considerable extent, are iiiieihpersed 

 among the ridges of mountains. These monopolize 

 nearly all the riches of this counti}-, the nionntams be- 

 ing too steep to retain them in any quantity. There ai e 

 portions of this region which, notwithstanding their 

 great elevation, enjoy a source of moisture and fertility 

 peculiar to their situation, — 1 mean the glades which by 

 reason of their elevation, being cooler than the coun- 

 try below, gather the mists rarrfiud by the heat in the 

 vallies and on the slopes of the mountains, and are in 

 consequence, watered duiing the summer months, with 

 continual light rains and fogs, while the country below 

 them is parched with diought and heat. Such is the 

 tract of country beyond Fort Cumberland in Alary- 

 land, called the Green Glades, which abounds in excel- 

 lent pasturage. All giades do wot however possess this
