JOURNAL OP THE PLYMOUTH INSTITUTION. 
Now this is much what was done in the case of the Keyham 
pick. The more massive portion of the antler has been pierced ; 
but in this case for the reception of the haft, and not of the tine — 
the complete implement being partly of wood (the' shaft) and 
partly of bone (the head). We have thus what we may call the 
third stage in the evolution of the pick. First there is the 
natural antler, as at Brandon; then the mortised and adapted 
antler, as at Carnon ; and lastly, the antler ceases to supply both 
shaft and prong, and a far more formidable and effective tool is 
made by turning the antler itself, and not merely a tine, to full 
account by hafting it with wood.
