noted hill of St. Gilles, near Liege. Gennete 

 has inferred that there are in this hill not less 

 than 61 beds of coal which are salient, or in the 

 mining language rise to the day, at distinct dis- 

 tances, but only 23 are worked. The coal 

 mines of Anzin, near Valenciennes, described 

 by Daubuisson, present singular large zigzags 

 which seem to defy all theory, except the prodi- 

 gious power of steam, arising from internal fires 

 and waters, and acting while the beds were yet 

 soft.

mit a description of the important coal mines, 

 even of England. Those of Newcastle are the 

 most celebrated, as they have supplied the capi- 

 tal for many ages. The land which covers these 

 mineral treasures, is often fertile, and lies on an 

 argillaceous sandstone, which forms excellent 

 grindstones, not only common in England, but 

 exported to other countries. Even the roads are 

 grand monuments of human industry, the tra- 

 veller being astonished to see large carts loaded 

 with coal, proceeding without horses or guides, 

 on wheels adapted to wooden ways defended 

 with iron. The coal mines of Whitehaven, on 

 the western coast, are the more remarkable, as 



comes dull, earthy, and, as it were, identified with the slip. J. de*
