The city of Cork is situated on an extensive al- 

 luvial deposite, formed from the sediment of the 

 river Lee* This river runs in a direction from west 

 to east, meets the tide at the city of Cork, and 

 after forming a frith interspersed with numerous 

 islands, empties itself into St George's Channel, 

 about fifteen miles to the eastward of the city. 



The vale in which the Lee flows is parallel with 

 the direction of the hills which occur in the neighbour* 

 hood. To the north of the city, there is a high con* 

 tinuous ridge of slaty rocks, which forms the nor- 

 thern boundary of the river for several miles. To 

 the south of the city, there is another ridge, of 

 lower elevation, consisting chiefly of limestone. 



The strata are nearly vertical, scarcely ever ob* 

 served declining above ten degrees towards the ho* 

 rizon. The dip is toward the south. The line 

 of bearing is by the compass, from W. N. W. to 

 E. S. E., and this direction is observed by all the 

 strata of the district with surprising regularity.
