thin cutting edge. Figs. 105 to 107 show a few examples. No. 119 is a .sort 

 of double pick, with slight indentures formed by chipping at each side at the 

 centre, as if to have a place for a withe or other handle, so that either of the 

 two ends which are pointed could be used. The two principal faces are 

 somewhat flattened. It is 10^ inches long ; but as one end is a little injured, 

 it was slightly longer in its original state. It is 21 inelies broad by | of an 

 inch thick, and appears to be formed of clay-slate which has been ground 

 and smoothed over or polished. It was found near the shores of Lough 

 Neagh, opposite Eandalstown. No. 116, which was found at the same place, 

 is lOi inches long, and made also, I believe, of clay-slate ; but, like 

 No. 1, of a fine quality. It has a flat side, which would appear to have 

 been used as a hone. The side shown is convex, and it terminates in a point, 

 that is cylindrical in section. No. 114 is a knife-like implement, with sharp 

 sides and point, but somewhat injured. It is G|- inches long and 1 inch 

 broad at the widest part. It was found on the shores of Lough Neagh, 

 at Toome. No. 109 is a knife-like implement, thin, with a sharp cutting edge 

 on each side. A portion at the point end has been broken oft', and the break 

 has been ground and smoothed. It has a handle which is pierced with a hole. 

 It was found at Culbane, and is still 6J inches long. No. 123 was evidently 

 made for a knife. It is 4|- inches long and 1^ inches broad at the widest part. 

 It has been ground to a cutting edge all round both sides, and has a sharp 

 point. It was found on the banks of the Bann, one mile from Toome, on the 

 Portglenone side. No. 122 is only a broken-oft' point of a knife. It was found 

 at Culbane. In addition tq - those figured and described, I have several 

 other interesting examples of a similar kind from Lough Neagh and the 

 Kiver Bann. 



Grinding-stonea. 



This paper would not be complete without some account of the stones on 

 which the clay-slate, axes, and chisels were ground into shape. A considerable 

 number of sandstone boulders have been found along the Bann, and many 

 have been dug out of the brick clay, which are smoothed or grooved on one 

 or more sides, presumably by grinding the stone axes on them. This, with 

 the exception of some small hand-specimens, seems to have been the only 

 kind of grindstone used from first to last, as the striae caused by rubbing back- 

 wards, forwards, and across on the sandstone are still visible on the faces of 

 the axes, crossing and recrossing in all directions. I have from fifteen to 

 twenty of these grinding-stones of various sizes. The New Zealanders not 

 only sawed their rocks into the form of axes and chisels in the way the early 

 inhabitants along the Baim did with clay-slate, but they ground their axes on
