The limestone and coal measures dip 

 In the quarries extending toward Milltown on the 



south-west 20° to 40° southward. 



Between the valleys of the Maine and the Guestin, 



undulated from north to south and from horizontal to 40° and 50° north and south. 

 On the East of the coal tract, and proceeding from north to south. 



At Parkmore and Shrewlana, north of Shanagolden . . 1 0° to 1 5° north-west. 



At Drumruagh, about five miles south of Newcastle 10° to 15° south-west. 



At Broadford, two miles west from Drumcullaghar. . 35° south-west. 



In the line of the Awenbeg river at Liscarol, the lime- 

 stone forms an inlet, an arched inflection from south 



to north, abrupted at the surface, bounded by and 



supporting the coal measures on the north, west, 



and south, in conformable position, under angles 



varying from horizontal to 40° and 50° north,west,& south. 



In the escarpment toward Kanturk, successively .... 50°, 45°, 20° south. 



To the east of Kanturk 30° south-west. 



North of the tongue of coal measures stretching east 



toward Doneraile the stratification of the limestone 



is not well displayed ; but the coal measures there 



visible form an arched curvature from north to 



south, abrupted at the surface, beyond which inflec- 

 tion, proceeding toward Mallow, their general dip 



is , 45° to 20° south. 



(60.) Within the interior of the coal tract the carboniferous limestone ap- 

 pears in knolls^ protruding through the coal measures at Maaling-, Tour and 

 Skullj and at Carrigdulkeen. 



At Maalingj situated near the left bank of one of the tributaries of the river 

 Allow^ and north-east from Newmarket,, the limestone rises to the surface in 

 two places on the higher grounds, disposed in strata flatly undulated from 

 north to south, and supporting the coal rocks in corresponding position. It is 

 traceable to the left bank of the river, and again in the more elevated lands 

 about two miles to the westward. At Maaling the limestone, where quarried, 

 is continuous, and of a black colour, containing courses of nodules of lydian 

 stone which extend about twenty feet in depth, but from which the subjacent 

 strata are free. In the latter is a bed one foot thick, almost composed of litho- 

 dendra. 



Tour Hill lies about six miles west from Maaling, and to the north-west of 

 Newmarket, forming high ground, 1329 feet above the sea. The limestone 

 here rises in dome-shaped strata, supporting the coal rocks, which latter con- 

 stitute the summit of the hill in the form of a cap, as well as the external 

 border of the limestone, all being in conformable position. The limestone
