The following boulders are at Neswick, in the parish of Bainton, 

 East Riding : — 



No. 1 was found in a field 250 yds. E. of Bracken Road and 

 distant from Neswick Farm about one-third of a mile. It interfered 

 with ploughing, hence dug out; attempts have been made to break 

 it up, and three barrow-loads of the block were removed by 

 hammers ; the present size is 4 ft. x 3 ft. x 1 ft. 6 in. It is very 

 compact ; one side has a joint face ; edges sharp ; rest rounded. 



No. 2 is 2 ft. 9 in. x 2 ft. 4 in. x 1 ft. 4 in. Rectangular ; surfaces 

 fairly flat. 



No. x is 1 ft. 6 in. x 1 ft. 6 in. x 1 ft.
