In the parish of Cundall, on the Leckby estate, five miles from 

 Boroughbridge, about a quarter of a mile above ' Elmire Ings,' as 

 given on the Ordnance Map, is a boulder; it is in the bed of the 

 river Swale, close to the Leckby bank ; it is entirely out of the water 

 when the river is very low ; 4 ft. 3 in. x 3 ft. x 2 ft, 9 in. ; is more or 

 less rounded; no striae or groovings ; Shap Granite"; is about 50 ft. 

 above sea-level. There is a long ridge of gravel and sand about a 

 quarter of a mile from where the boulder lies. 



YOULTHORPE, NEAR STAMFORD BRIDGE (EAST RIDING). 



ROBERT MORTIMER, 

 Fimber. 



At Youlthorpe, between Bishop Wilton and Stamford Bridge, is a 

 large isolated boulder ; had not been moved by man until recently, 

 when it was carted into the farmyard of Mr. Hawkins. Is now used 

 as a mounting block; 3 ft. 9 in. x 2 ft. 9 in. x 2 ft. to in. Youlthorpe 

 is on the Keuper Marl and not far from the foot of the Chalk 

 escarpment of the Wolds. Pure white, very quartzose. Sandstone. 



SEAHAM HARBOUR (Co. DURHAM). 



Rev. ARTHUR WATTS, F.G.S., Etc. 

 Vice-Principal, Bede College, Durham. 



This boulder is in the grounds of Mr. R. L. Hawthorne, Haw- 

 thorne Tower, Seaham Harbour, on north side of Hawthorne Drive 

 and W. of the Tower ; was removed from an adjacent field, when 

 draining, to its present position ; 5 ft. 10 in. x 3 ft. 8 in. x i ft. 3 in.; 

 weight, I ton, 18 cwt. ; sub-angular; it originally pointed, by its long 

 axis, 20° E. of N. magnetic, 42° E. of N. true bearing. There are 

 seven grooves across the stone — five perfect, two imperfect; there 

 are two sets of striae, the one set of six are nearly obliterated by the 

 other numbering about seventy ; the smaller groups of striae are 

 nearly in the line of the longest axis, the larger group make an 

 angle of about 60° with the long side. It is Encrinital Carboni- 

 ferous Limestone, and the nearest in situ that I know of is twenty-five 

 miles due west at Frosterley ; it has no popular name or legend ; is 

 about 80 ft. above sea-level; it was discovered in March 1879, ^nd 

 is not indicated on any map ; it formed part of a mass of clay, sand, 

 gravel, and boulders, that is seen in a coast section to lie in a hollow in 

 the Magnesian Limestone about i;^y^JHi^|^^d 60 ft. or more deep.
