ON THE EERATIC BLOCKS OF ENGLA^D, WALES, AND IRELAND. 113 



boulders of vsfhicli upwards of thirty will average 1 ft. 4 in. x9 in. and 

 over seventy others are over a foot in diameter. The larger ones are 

 sub-angular ; the smaller ones rounded. All have no doubt been con- 

 veyed from adjacent fields. No striffi or groovings are to be seen on 

 exposed surfaces. They are different kinds of sandstone. They are about 

 150 ft. above sea-level. 



On Miss Craven's estate, in the village of Cayton, about 300 yards N. 

 of the church, and on the main road to Scarbro', is a group of nine 

 boulders, four of which are whinstone, and upon an average 1 ft. 11 in. 

 X 1 f t. ; the other five are sandstone and average 1 ft. 8 it. x 1 ft. 2 in. 

 The whinstones are mostly sub-angular ; the sandstones angular. 

 There are no strife or groovings exposed. They are about 150 ft. 

 above sea-level. Some of them are entirely exposed, the rest being 

 partially covered with other stones and soil. 



On Miss Craven's estate in the village of Cayton, and about 250 yards 

 N. of the church, in a by-road called North Lane, are a number of 

 boulders, the seven largest of which I have noted as follows : — No. I — 

 1 ft. 11 in. X 1 ft. 4 in. X 1 ft. ; red sandstone ; angular. No. 2 — 2 ft. 6 in. 

 X 1 ft. 2 in. X 1 ft. ; whinstone ; angular. No. 3 — 1 ft. 10 in. x 1 ft. 4 in. 

 X 1 ft. 3 in. ; whinstone; rounded. No. 4—1 ft. 5 in. x 1 ft. 3 in. x 1 ft. ; 

 hard, grey sandstone ; sub-angular. No. 5 — 1 ft. 6 in. x 1 ft. X 9 in. ; 

 whinstone ; rounded. No. 6 — ^1 ft. 4 in. X 9 in. X 7 in. ; mottled granite ; 

 sub-angular. No. 7 — 2 ft. 4 in. x 1 ft. 2 in. x 6 in. ; whinstone ; angular. 

 I could not observe any strias or groovings. The rising ground is prin- 

 cipally composed of drift, gravel, sand, and clay, whilst the hollows are 

 filled with deep peat bogs. 



Note. — The great bulk of the boulders in this district are com- 

 posed of sandstone and whinstone; of these thousands have been broken 

 up and used to mend the roads from time unknown. There is no doubt 

 about the roads having received their supply of metal from this source. 

 Those left behind (as above) are those which could not be broken up, 

 or which have been taken out of the land at a recent date. 



Lebherston, near 8carhro\ — On Mr. Wardell's estate, in a grass-field 

 at the E. end of the village, and about 100 yards W. of the Scarbro' 

 and Filey road, 4 ft. 3 in. x 2 ft. 5 in. x 2 ft. 7 in., but evidently one-half 

 of it is embedded ; sub-angular. Longest axis N.W. to S.E. ; should think 

 it has not been moved. There are remains of several groovings, which 

 are much worn, and there are also striae on the side of the block, in the 

 direction of the longest axis. "Whinstone. Is 200 feet above sea-level. Is 

 near the top of a ridge of gravel drift. 



On Mr. Jackson's estate, at tbe E. end of the village, near a yard door 

 on the W. side of the road, 2 ft. 3 in X 1 ft. 9 in. x 2 ft. 3 in. Angular, 

 and is used as a stepping or mounting stone. Has been moved, but is 

 known to have been in its present position for more than a century. No 

 striae or groovings. Whinstone. 200 ft. above sea-level. No doubt has 

 been obtained from gravel drift in vicinity, but now rests on the surface 

 soil. 



On Mr. H. Watson's estate. Is in a grass-field, about a quarter mile 

 N. of the Gristhorpe Railway Station, Hull and Scarbro' branch, 

 4 ft. 2^ in. X 2 ft. 5 in. X 3 ft. 6 in., and partially embedded. Sub- 

 angular, flat on one surface. Long-shaped ; its bearing N. and S. There 

 appear to be some striae, which have become very faint from exposure, 

 but the stone being grown over with lichen, they are difficult to determine.
