96 Lincolnshire Notes & Queries. 



records a boulder of this rock at Kilnsea near Spurn.* This 

 is now in the garden of Mr. H. B. Hewetson, at Easington. 



Inland, at Royston near Barnsley, which is just south of the 

 line of the Humber, this granite has been found, f and Messrs. 

 Corbett and Kendall report a boulder at Balby near Doncaster ; J 

 this and the Barton, South Ferriby, Irby, and Goxhill 

 specimens described above, are the only records that I know of 

 for the country immediately south of the Humber. 



Whilst in the quarries at Wasdale Crag in Westmorland 

 last Easter (it is from this place that all the boulders of Shap 

 Granite have originally travelled) I obtained a quantity of hand 

 specimens of the rock, and shall be very pleased indeed to send 

 a piece to anyone in Lincolnshire interested in the subject, who 

 is unacquainted with the rock, in the hopes that a constant 

 look-out may be made for c Snaps.' I feel confident that many 

 other boulders of this granite will be found in Lincolnshire 

 they only require looking for. The rock cannot very well be 

 mistaken, it is a 'pepper-and-salt '-looking granite, of a pinkish 

 colour, containing large rectangular crystals of flesh-coloured 

 felspar, which vary from an inch to an inch and a half in 

 length, and are about half as wide. The matrix consists of 

 minute crystals of colourless quartz, pink felspars and black 

 mica, together with other minerals. There is also a whitish 

 variety of the same rock, the ground-mass in this case contain- 

 ing several small specks of white felspar, which give it a 

 generally whiter aspect. This granite has recently formed the 

 subject of an exhaustive paper by Messrs. Harker and Marr.
