_ which passes up inside the auger. When the proper depth has been 
bored, the thin wedge (C) is driven into the hollow auger from the 
shank end and passes between the cylinder of wood and the side 
of the auger, thus wedging it fast. Then the first twist of the auger, 
in withdrawing it, breaks off the cylinder of wood even with the 
inner end and it is withdrawn in the auger. The wedge is then 
removed, pulling the wood cylinder with it. If this is done care- 
fully, and the wedge has not been driven in too tightly, the wood 
cylinder will remain unbroken. The cylinder is then laid in a 
trough of wood (elder is good) hollowed out to receive it and the 
top shaved off with a sharp knife at right angles to the rings, which 
makes them easy to count and measure.
