It was obviously intended to be set as an adze or as a hoe, and not as an axe.
The cutting edge is formed by the intersection of two transverse facets.

SOME NOTES ON "MOORLOG," A PEATY
DEPOSIT FROM THE DOGGER BANK
IN THE NORTH SEA.
By HENRY WHITEHEAD and H. H. GOODCHILD.
WITH A REPORT ON THE PLANT REMAINS.
By CLEMENT REID, F.R.S., and (Mrs.) ELEANOR M. REID.
THE writers have had exceptional facilities for studying a
curious and little known deposit from the floor of the
North Sea. Large quantities of the deposit are lying on the sea
floor off the Dogger Bank, about 60 miles off the Yorkshire
coast. This material, known to the fishermen as "moorlog" or
"merlog," being a source of annoyance to them, because it
chokes up the trawl, is broken in pieces and thrown overboard,
hence very little of it comes to land. Through the kindness of
several captains of the "Gamecock" fishing fleet, Mr. S. H.
Goodchild has been able to obtain sufficient material for its
detailed study, and for us to submit samples to specialists for the
determination of the organic remains. We venture to think that
the results may interest others, and at the invitation of the
Honorary Secretary we have brought the paper before the Essex
Field Club.
The specimens of peat or moorlog that we have obtained
have been brought up in the trawl from the north and south
slopes of the Dogger Bank, principally between latitudes 55° and
56° N. and longitudes 3° and 4° E. Through the kindness of Mr.
J.O. Borley, M.A., the Director of the Lowestoft Laboratory of the
British Marine Biological Association, we are allowed to quote
