3. Concha, Pectinites dicta. The shell called P. oc- 

 curred in great numbers in these stones. Seldom was 

 any side of a stone hewn flat on which was not found 

 one, if not more of its shells. The number of cockles, 

 Strimmorna, was also not equal upon all the shells. 

 The small ones, the thickness of a nail, here formed the 

 greatest number. 



4. Concha, Oftrea dicta. Oyster shells. We saw two 

 of these which lay in the side of a large stone which we 

 had not liberty to hew asunder. They were so naturella 

 that it seemed as if some one had taken an oyster shell 

 and crammed it into the stone. The man who had the 

 supervision of the mine said that such natural oyster 

 shells are very often found in this stone when it was hewn 

 asunder. These oyster shells, as well as the aforenamed 

 Pectinites, always lay, according to the supervisor's 

 account, horizontal in the stone as it stands in the mine, 

 or so that they turn the convex side down and the con- 

 cave up. 



[T. I. p. 293.] We could not see many heterogenea 

 here, nor did the supervisor of the miners know of many 

 kinds, however much we questioned him about them. 



The use of this freestone, and the purposes it is used 

 for, are various. The principal is to build houses of it, 

 when it has first been hewn here at the mine into a 

 four sided oblong form. Likewise it is used for win- 

 dow-frames and door-posts, and arches over fire- 

 places, windows, and doors, for several kinds of 

 pedestals and pillars, the bottoms of baking-ovens, and 

 other such things. Most of the churches in this 

 district are entirely built of this stone, which indicates 

 the great age of this stone-mine. A quantity of it is 

 carried to various gentlemen's estates round to build 

 houses and other things. The small pieces which are 

 struck off and chipped in the mine, when the stone is
