ADAMSON: THE YORKSHIRE liOULDER COMMITTEE. 3II 



No. 3. In the Back Lane, near the ' Duck Pond,' i ft. 10 in. x 

 1 ft. 6 in. x 1 ft. ; no striae or groovings ; has not been moved. 



No. 4. In the field on W. side of 'White Horse Farm'; dimen- 

 sions cannot now be given, as it has been sunk by the farmer to 

 escape the plough. It was too heavy to remove, and too hard to 

 break. 



There are many smaller ones in walls or on road-sides, scattered 

 over the parish, varying from the size of No. 3 downwards. They 

 are all of Basalt or Whinstone, locally called ' blue stone'; the nearest 

 dyke is about three miles north, near Tynemouth and Cullercoats ; 

 the size of the largest suggests they may have travelled from the 

 ' Great Whin Sill.' Harton is from 50 ft. to 60 ft. above sea-level. 

 They are seen only when on the surface, but the plough frequently 

 reveals them, and draining still more frequently, so that they occupy 

 the whole of the clay deposit which covers this area to a thickness 

 which varies greatly in different localities. 



The Haddockstones, near Ripon. 

 The attention of the Committee has been called by the Rev. J. 

 Stanley Tute, B.A., Vicar of Markington, to a group of remarkable 

 blocks, which gave the name to the farm of Haddockstones, four 

 miles S.W. of Ripon. The word ' Haddock ' is a local name for a 

 shock of corn. The Chairman and other members of the 

 Committee, accompanied by Mr. Tute, visited the farm on June 1st. 

 The blocks are of sufficient size to be visible at a distance of several 

 fields, and lie along a low escarpment of the same rock as that from 

 which they are derived, viz., a Sandstone in the Third Grit Series. 

 Few of the blocks are undisturbed, and their planes of stratification 

 rarely coincide with the bedding of the rock beneath. Some exhibit 

 apparently modern surfaces, as if pieces had been removed by 

 wedges. From the position of these blocks along an outcrop of 

 precisely similar sandstones, the Committee consider it likely that 

 they are merely weathered fragments, nearly in situ, and concur with 

 Mr. Tute that they cannot be claimed as erratics. 



The ' Fourstones,' near Bentham. 

 The ' Fourstones ' was reported by Mr. Balderston, of Ingleton, 

 to the Yorkshire Boulder Committee, in 1887, as an erratic block, 

 but there were several points of similarity between this block and 

 the 'Hitchingstone,' as the latter had been erroneously reported to 

 the British Association, in 1874, by a private individual, as an erratic, 

 whereas it was demonstrated in 1SS7 that it is not one, it was 

 deemed desirable that the 'Fourstones' should be closely examined 

 before a report was forwarded. 



Oct. 1889.
