MORRIS BRITISH FOSSILS. 189 



It is not here necessary to dwell upon all the interesting fact5 

 whiuh presented themselves in the examination of this tract of country ; 

 it being well known that the American Continent is exceedingly 

 rich in coal, which as soon as the forest is consumed will be fully 

 developed. By far the greater part of the coal deposit of America 

 is of the same age, and presents a great similarity of attendant cir- 

 cumstances with our own ; and, although this country and America 

 are so wlely separated by the Atlantic Ocean, no better preparation 

 can be made for studying the great western coal deposits than by 

 obtaining a knowledge of our own Welsh coal-field.
