JUDD THE SECONDARY ROCKS OE SCOTLAND. 



171 



series of specimens in the Dunrobin Museum, was extensively em- 

 ployed in prehistoric times as a substitute for flint in making arrow- 

 heads, knives, and other weapons and implements. 



The hard sandstone rock, where exposed at the surface on Hare 

 Hill, has retained in a remarkably beautiful manner the striation 

 and grooving impressed upon it by the great Strathbrora glacier, of 

 which this hill at one time evidently formed the northern boundary. 

 "Whenever the turf and soil are removed from the surface of the hill, 

 these markings, in a beautiful state of preservation, are revealed to 

 view. 



The casts of the exterior and interior of shells, which, however, 

 are often distorted by pressure, are retained in a most perfect 

 manner by this fine-grained rock ; and the number of species yielded 

 by it is very considerable. The fauna, however, though more 

 numerous, is evidently the same as that we have already noticed as 

 obtained from the yellow and grey sandstones at Fascally.
