ADAMSON : THE YORKSHIRE BOULDER COMMITTEE. 299 



originally rounded, but has weathered away ; no stria; or groovings ; 

 Mountain Limestone with casts of Producti and Encrinites; it rests 

 on Boulder Clay about 150 ft. above sea-level. 



Note. — This stone was used for mounting purposes in the days 

 of the grandparents of the present occupants. 



25. In front of this house, forming a broad footpath, are about 

 200 boulders, averaging 8 in. in diameter ; they are composed of 

 Limestone, Whinstone, and Sandstone, the latter predominating ; 

 they are rounded to sub-angular, but of course, from wear and tear, 

 no striae or groovings are now visible. 



26. In the parish of Thornton-le-Clay is a footpath over a mile 

 in length ; it is paved with boulders varying from 1 ft. 6 in. x 7 in. x 

 6 in. to 6 in. in diameter. The footpath is about 4 ft. wide, and is 

 flanked by the larger boulders ; they are composed principally of 

 Carboniferous Sandstone, a few Whinstones, Granites, and Mountain 

 and Liassic Limestone; percentage about the following — Granite 1, 

 Whinstone 3, Mountain and Liassic Limestones 18, Carboniferous 

 Sandstones 78. Generally speaking, they are rounded from usage, 

 but a few of the larger are sub-angular. 



Note. — This footpath has a certain degree of celebrity, as it was 

 constructed by the orders of the famous Sydney Smith from stones 

 collected from adjacent fields. It will be remembered that Sydney 

 Smith filled the benefice of Foston-le-Clay (the adjoining village) 

 from 1809 to 1 83 1, and his memory is still green in the neigh- 

 bourhood. 



Thornton-le-Clay. 



27. About the centre of the village of Thornton-le-Clay (nearest 

 Railway Station is Flaxton, N.E. of York) is a boulder forming a 

 corner-stone in Mr. Danby's timber yard ; 2 ft. 5 in. x 1 ft. 7 in. x 

 1 ft. 8 in. out of ground ; sub-angular ; has been moved to its present 

 position ; no striae or groovings ; Mountain Limestone ; now rests 

 upon Boulder Clay and Gravel, 150 ft. above sea-level. 



28. Group. — In the parish of Thornton-le-Clay, upon farms in 

 the occupation of Messrs. John Buckton and W. Spaven, and also upon 

 premises occupied by Mr. Danby, are upwards of 1,100 boulders. 

 The largest measures 2 ft. x 1 ft. n in. x 10 in., the smallest being 

 10 in. x 9 in. x 6 in. They are principally sub-angular to rounded. 

 The whole of these have been taken from the adjoining fields, and 

 are now in heaps for the mending of roads, etc. No striae were 

 observed. They are chiefly composed of Mountain Limestone, 

 Carboniferous Sandstone, Lias, Basalt, and Granite. They were 

 derived from Boulder Clay and Gravel, 150 ft. above sea-level.
