Burton: Lincolnshire Coast Boulders. 



95 



there, many of the furrows were lined with the stones which 

 had been washed out, while others were still bedded in the 

 mass. 



On going - to the Yorkshire coast a totally different state of 

 things presented itself. Shingle instead of sand. Stones 

 smooth and rounded instead. of rough and angular — all pointing 

 to a power at work entirely at variance with that on the Lincoln- 

 shire coast. 



I walked from Hornsea a long way on the shore towards the 

 north. The cliffs were full of boulders, which, excepting a few 

 which had been rounded before they were embedded in the 

 mass, were as angular as those at Sutton. Those also which 

 had just left their beds, and were lying near the cliffs, were 

 angular. All the rest were ground and polished by the action 

 of the waves on the stony beach. The stones at Sutton, how- 

 ever, are all, with few exceptions, unworn and angular; because 

 the matrix from which they are derived lies beneath them, and 

 they have no distance to travel. 



The next day I went to Easington and walked towards 

 Withernsea, where I had the good fortune to meet with Mr. T. 

 Sheppard, of Hull, who kindly pointed out the shell beds and 

 other interesting sections of the Holderness cliffs. 



The day following I went to Spurn Point, and there the 

 boulders are all rounded and worn, as they naturally would be 

 after their travel down the coast. Spurn Point itself was a wide 

 tract of sand, as smooth as at Sutton. This, however, may 

 probably vary from time to time as winds and tides affect it. 



One more question remains, which Mr. Harker makes a 

 point of, and that is the size of the boulders on the Lincolnshire 

 coast ; but he has mistaken- what I intended to convey in my 

 first paper on the subject. When I mentioned sizes I alluded 

 only to those specimens which were there described, and not to 

 the boulders on the coast generally. Lincolnshire coast boulders, 

 however, are not so large as those found on the Yorkshire coast, 

 but there are some to be met with ranging in length up to about 

 12 or 14 inches, while a few are larger, and there is no small 

 shingle. Perhaps, to account for this, the boulders in the 

 4 Purple clay' are usually of less size than those in the Boulder 

 clay, or, again, the larger boulders of the Lincolnshire coast 

 may have been carted off for road making as mentioned in m} 

 first paper — or they may have been taken for ballast in the 

 small sailing boats that ply for hire, and on off-days do a little 

 fishing, at places like Sutton and Mablethorpe. The onh two
