I do not consider that either of the foregoing objects is of any 

 great antiquity. They may both indeed be comparatively modern. 



The most interesting of Mr. Driver's own finds is the perforated stone 

 figured in PI. Ill, Figs. 1, la. Unfortunately, little more than one half 

 of the object has been preserved, but from what remains restoration is 

 easy. The instrument is made out of a bit of actinolite schist. It is all 

 but as broad as long, and oval in shape, with one end much broader than 

 the other, which is a much larger segment of a much smaller circle ; it 

 has, in fact, much the outline if an irregular echinoid of the genus 

 Echinodiscus. It was apparently slightly and equally convex in every 

 direction on both its faces, and rounded at the sides and ends, the broader 

 one of which latter appears to have seen hard service. It has a parallel- 

 sided shaft-hole almost in the middle, and in the margin of this hole 

 on one side a broad notch has been cut cleanly and obliquely across the 

 fissile planes of the stone and may possibly have been intended to receive 

 a pin for securing it firmly to a wooden shaft.

The next object to be noticed is a thin and flattish celt (PI. Ill, 

 Figs. 2, 2a.) probably of black trap. It never appears to have been 

 polished all over, but only to have had the principal inequalities of its 

 surfaces smoothed off and its edge ground. Its sides, which were 

 possibly once narrowly rounded, are now in a much battered and flaky 

 condition ; the butt has been much chipped since the rough polishing was 

 done ; and the cutting edge, which is unequally sloped on the two sides, 

 is much broken and blunted by rough usage ; all these lesions are 

 probably of the same date, for they are all weathered to identically 

 the same dark greenish grey colour ; but a large chip at one end 

 of one face of the cutting edge is darker, that is to say, is less weathered, 

 and hence probably of later date, than the rest, but even it presents a 

 strong contrast in colour to the recent chip at the opposite end of the 

 same face by which the unaltered black rock has been exposed.
