the crag gasteropods. The deposit's geological relationships were
also described by him.
The group has asked the Field Club to buy the 21/2 inch to 1
mile maps of the County and this has now been done, and these,
together with a list of gravel pits, clay pits and chalk pits com-
plete with map references and owners, kindly supplied by the
County Planning Officer, have been deposited in the Museum
library where they may be consulted by members.
Report forms, from which it is hoped a register of temporary
sections will be compiled, have been prepared. These, together
with instructions on its completion, may be had from the Group's
Secretary. These need no geological knowledge for their filling
in and it cannot be too strongly stressed that the value of a large
number of records of this kind is very great.
Members are invited to send in any references to the geology
of the County which they may find so that the bibliography of
the County's geology may be completed. The information needed
is book title, date, volume, page number, title of article, and
author. It should be sent to the Geological Group Secretary.
OCCURRENCE OF THE SKIPPER OFF THE ESSEX COAST
In a communication to Nature, two members of the Club, A.
C. Wheeler and M. N. Mistakidis, record the presence of this fish
(Scomberesox saurus) in the Southern North Sea and Thames
Estuary. Several specimens were caught in the River Crouch in
December 1959 and reports of catches by fishermen at Southend
and Leigh-on-Sea are noted. The Skipper had only been reported
once before from Essex.
A more complete discussion of the occurrences may be
obtained from the above-mentioned paper*.

My first impression of "A Poacher's Tale", is that it is mis-titled and
should have been titled "By Hook or by Crook".
