340 MINERALOGY OF THE REDHEAD. 



cipitous, broken, and indented cliffs. The high- 

 est point, where there is a precipice rising from 

 the sea to the height of 254 feet, is at the flag- 

 staff to the eastward of the House of Ethie, the 

 seat of the Right Honourable the Earl of North- 

 esk. All the rocks of this promontory, are of a 

 reddish colour, and from that circumstance, it has 

 been denominated by mariners the Redhead; the 

 inhabitants of the district, however, restrict the 

 name to the high tocks which appear to the south 

 of the ruins of St Murdoch's Chapel. 



From this promontory, inland, the surface falls 

 with a gentle slope, and at last forms the plain 

 through which two small rivers, the Brothick and 

 the Lunan flow. The Bivthick Burn, towards its 

 mouth, runs in a southerly direction, and falls into 

 the sea at the Town of Aberbrothick, commonly 

 called Arbroath. It winds its course through a nar- 

 row valley, which is from one to two hundred yards 

 in breadth. The sides of the valley, which con- 

 sist of strata of sand, of coarse sand and gravel, 

 though much waved, are in general parallel to each 

 other*, the salient angles of the one corresponding 

 with the receding angles of the other ; the bottom 

 consists of fine earthy sand and gravel. In the 

 centre of this valley, there is a conical hill, on the 

 summit of which the ancient Church of St Vigeans 

 is situated. This hill is composed of soft sand- 

 stone, which is covered to the top with a thick 

 coating of gravelly mould.
