Vorkshin' Boulder Committee : SixteentJi Year's Work. 73 



Secretarv records a rock resemblin*^ the peculiar nodular i^abbro 

 of Imenais, near Grimstad. A very satisfactory identification is 

 that by Mr. Stather of a boulder absolutely identical in structure 

 and constitution with the elaiolite syenite (foyaite) of Kvelle, 

 near Larvik. 



Reported by W. Gre(;son, F".G.S. 



Aldfield. Five miles west of Ripon. 



One diabase, 1 1 in. x 7 in. x 5 in. 6oo feet O. D., on millstone 

 i^rit ; no angles.

 ESCRICK, NEAR YORK. 



Several boulders of a Carboniferous limestone containing" 

 manv Brachiopods have been found here, which are quite unlike 

 anything- I know in the Craven area. Mr. W. Horn, of Leyburn, 

 says they are different from any limestone in Wensleydale, and 

 sug-gests Swaledale as their place of orig^in. A sing^le specimen 

 had previously been submitted to me from the same locality of 

 a yellowish, verv crystalline limestone, which I recognised as 

 identical in colour and structure with that forming- the matrix 

 of specimens oi Woodocrimis from the famous quarr_\' near 

 Richmond. The corroboration is interesting, and may be 

 valuable, as no distiiictive Swaledale rock had previously been 

 found in the Vale oi York. The specimens were all found by 

 Mr. E. M. Baines. 



COXWOLD. 



In a quarry beside Shandy Hall, and in dig-g-ing foundations 

 for a house a little nearer the villag-e, the erratics consisted 

 mainly of Carboniferous sandstone, limestone, and chert, with 

 a few small boulders (up to about 8 inches in diameter) of 

 Borrowdale andesite. A special search was made for Cheviot 

 porphyrites, with negative results. 



KiLBURN. 



At corner of a road quarter-mile south oi the villag-e, 

 Borrowdale andesitic ^sh, containing- many g;arnets. Roadside 

 heap in the village, one Shap granite. 



Reported by Rev. E. iMAl'LE COLE, ;M.A., F.G.S. 



Carxabv. 



In digg-ing- a hole for a g"ate-post in the main street of the 

 village, o\\ hig-hroad between Bridlington and Driffield, one Whin 

 Sill, 22 in. X 19 in. x 12 in., polished and flat. The boulder 

 now lies by the roadside, opposite the blacksmith's shop.
