 EAST YORKSHIRE.

(plate v.). 



The specimen figured on the attached plate (Plate V.) are 

 of unusual type and should be placed on record. 



The first is a hammer-stone of somewhat rare form (figs, i 

 and irt) from Nafferton in East Yorkshire. It measures 2| 

 inches in length, 2 inches in width, and i\ inches in thickness. 

 It is oval in shape and bears evidence of considerable use, 

 particularly at one end ; and at the sides are two depressions 

 which have been carefully worked, evidently for the reception 

 of the thumb and finger. Each depression measures i inch b}' 

 I inch, and is about a quarter of an inch deep in the centre. 

 This hammer-stone has evidently been made from one of the 

 oval quartzite pebbles such as are found in fissures and hollows 

 on the Yorkshire wolds ; and have obviously been derived from 

 some earlier geological deposit. It is exceedingly tough, and 

 is of metamorphosed sandstone. Hammer-stones after this 

 type are figured in Evans' 'Ancient Stone ^^Implements,' (see 

 figures 160, 161, 163, 164 and 165), some of which are East 

 Yorkshire specimens. Mr. Mortimer of Driffield, in his museum, 

 also possesses one or two, but in all these cases the depressions 

 for the thumb and finger are made on the front and back of 

 the pebbles, or hammer-stones, and not on the sides. The 

 Nafferton example is the first I have noticed of this par- 

 ticular type. 



The other specimen (see figs. 2 and 2a) is a very unusual 

 form of adze from Bridlington. At any time these adzes 

 are not very common in East Yorkshire, and adzes of flint, 

 the material of which the Bridlington example is made, are 

 exceedingly scarce. 



The specimen figured is also remarkable from its small size 

 and delicacy of finish. Its entire surface has been ground 

 down and ^polished. The sides have been left slightly square, 

 and the cutting edge has been formed by rubbing down a 

 triangular portion of one side of the implement. The adze 

 measures 3f inches in length, i inch in thickness, i|- inch at the 

 cutting edge, and half an inch at the butt. From a compar- 

 tively recent chip in the centre of the cutting edge it is evident
