The snag is, if you are using such a gadget on a Nature Reserve and aiming it at some Ducks or Waders then your intentions might well be misconstrued by the wardens! My own telescope is a "Perl Turret- scope" and my binoculars are "Canon" 7 x 50. HISTORIC PUBLICATIONS FROM THE ESSEX FIELD CLUB I have been sorting through the stocks of the Club's publications so that an updated list can be produced. In the recesses of our cup- board at the Passmore Edwards Museum are very small numbers of publications long thought to be but of print. Any unsold to members three months after this notice appears will be disposed of at their full value to non-members.
