Kivcrsuux Lievresaiiil St. Mamicc; that it also dips deep 

 to the soutliward from the siiorcs of the great chain of 

 lakes lying between those rivers; and that it runs parallel 

 with the Oilawa as far as Grenville, from whence it joins 

 the chain extending from the Shewanahegan ; we think it 

 can scarcely admit of a doubt, but that the whole extent of 

 country lying within that area, is of the same primitive for- 

 mation covered with a silecious sand, as that which con- 

 stitutes the njountain belt already described. 



V\erc it necessary we could adduce many instances of a 

 country similarly formed. We particularly remember one 

 in Devonshire, England ; in the district locally called thi; 

 South idams: this tract of country lies between the sea and 

 the Dartmoor Hills, and is remarkable fur its fertility. — 

 About fourteen miles from Exeter is a flat called Bovey 

 Heath, famed for the submerged wood, or Bovey coal. — 

 This heath consists of an extensive bed of pij)e-clay over- 

 lying the wood coal, and covere<l with a deposit of san<l 

 which forms ihc upper surface ; if we except the thin laver 

 of peat earth, the gradual accumulation of ages. Numer- 

 OU.S ilint (puirries are found on the surface abounding in 

 organic remains. 



This extensive level is situated at the foot of the Dart- 

 moor Mills, about five miles distant from the sea coast, 

 and the intermediate space is occupied by a hilly country 

 called Iluldon, partly formed of sandstone and partly of 

 lime rock, covered with a rich red loam. 



'Jhe whole extent of the South Hams is about forty iniles 

 in length and of varied width, I) ing, as above ob«erve«l, 

 ut the foot <»f a range of barren hills, and hearing a striking 

 resemblance, in many of its most important features, (o the
