boniferous sandstones of various kinds, gannistei- and millstone grit, 

 porphyries and basalts, quartzite, vein quartz, black flints, chert, &c. 



Boulder No. 1. — 1 ft. 10 in. xlft. 9 in, xl ft. 8 in. ; longest axis N.E. 

 to S.W. ; sub-angular ; Halleflinta, not unlike some Lake Country rocks 

 in character ; no groovings or striations observed. 



Boulder No. 2.-2 ft. i 1 in. x 2 ft. 0| in. x 1 ft. 7 in. ; longest axis N.E. 

 to S.W. ; rounded ; a coarse grit, almost a conglomerate, with large 

 quartz pebbles ; no groovings or striations observed. 



A mythical personage, half giant, half hermit, known as William of 

 Lindholme, is said to have lived at Lindholme and to have brought the 

 above stones, known traditionally as the ' Thumb Stone ' and the ' Little 

 Finger Stone,' to their present position. 



Mr. J. W. Davis, F.G.S., Hon. Sec. Yorkshire Geological and 

 Polytechnic Society, furnishes the following note on the groups of 

 boulders at Norber, near Clapham : — 



All sizes up to 16 to 20 feet in diameter ; angular ; slight striations ; 

 under surface rarely striated. Rock identical with that of the boulders 

 is found in the valley to the north at various spots, varying from a mile 

 to a mile and a half from the place where the boulders are most thickly 

 congregated. They are composed of Silurian grit and rest on mountain 

 limestone ; 800 to 1,250 feet above the sea ; area covered is three-fourths 

 of a mile square ; several hundreds in number ; all exposed on the surface. 

 In many instances the masses of Silurian grit have protected the lime- 

 stone immediately beneath, whilst the surrounding surface has been 

 removed, and they now stand on pedestals of limestone, 12 to 18 inches 

 in height.
