196 THE ESSEX NATURALIST. area was between Hamford Water and the Stour, where there was a group of nine. The only decoys at any distance from salt water are Wormingford and Felsted. The most effective way to obtain an impression of the positions of the decoys is to con- sult the map in A History of the Birds of Essex, on which all but two are marked. Although the amount of information available to us regarding the decoys of the County is very limited, yet we are fortunate in having at our disposal a first-hand account of the art of decoying, probably as good as ever was written. Fortunately it was based on experiences obtained at an Essex pond, namely Marsh House. The article appeared in The Field in 1868, under the title "Decoy Ponds," and was signed "P.," but Christy states that it was written by Mr. Jacob L. Pattisson, private secretary to the Rt. Hon. W. H. Smith. This account is most valuable and as it relates to Essex a great part of it is used here much in the words of its writer. The following particulars are derived more especially from a well-known pond near Tillingham, on the coast of Essex, where the writer (J. L. P.) has lately through the kindness of the owners witnessed during several days and at the most favourable time of the year the operations being carried on with great success. To these gentle- men and their skilful and obliging decoyman—one of the Skelton family, mentioned in almost every treatise or description that has been written on decoys, and who have been hereditary decoymen from father to son in Lincolnshire, Norfolk and Essex for many generations past—he has to give thanks. Decoy ponds formerly were of great size, those in Norfolk being as much as a hundred acres in extent, the largest nearly a thousand, but experience proved that fewer were caught than in smaller ponds and that the most successful of all were not more than two acres in extent. The pond at Tillingham covers about an acre and a quarter. It stands in the marshes, about half-a-mile from the sea-wall, on the other side of which, at low water, is a great expanse of mud extending nearly two miles, and where in severe weather thousands and tens of thousands of Wild Geese, Duck, Wigeon, etc., will congregate, while still more numerous flocks of Plover, Dunlins (Oxbirds), Curlew, etc., skim up and down among them. The decoy is surrounded by large beds of tall-growing rushes and plantations of willow and other trees, which serve at the same time to shelter the wild-fowl, and to hide from them the approach of human beings and other things likely to alarm them. Wild-fowl are easily alarmed by noise and everything is done to maintain silence. The sense of smell is also strongly developed, and they easily scent and take alarm at anyone approaching on the windward side. It is said that
