222 THE ESSEX NATURALIST. beginning of the 16th century, where hot tea and coffee were welcome adjuncts to our picnic lunch. Leaving Benfleet, the party proceeded through the marshlands in the direction of Leigh (the rain having by now ceased) and so, by a notably muddy lane up the hillside to various hilltops whence glorious views were obtained over the flat land of Canvey at our feet, across the Thames estuary, to the Kentish shore, with the faint outlines of the North Downs beyond. Progress over the route was leisurely, so as to afford the naturalists ample opportunity for studying the flora and fauna of the district—an opportunity of which full advantage was taken. Arrived at Hadleigh, tea was taken in the cafe of the new Kingsway Cinema, following which a visit was paid to the parish church, a small but unspoilt example of a 12th century Norman church, with apsidal chancel and large cinquefoiled hagioscopes flanking the chancel arch and with some interesting remains of mediaeval wall-paintings. In the absence of the incumbent, Mr. Salmon gave a brief description of the building. Continuing the ramble, Hadleigh Castle was next visited, by per- mission of the Salvation Army authorities, the picturesque position of its ruined towers, on a bluff overlooking the Thames estuary, being much appreciated by the visitors. Mr. Salmon read some notes on the history of the Castle, from which the following account is abstracted. Hadleigh Castle was built some time before 1230 by Hubert de Burgh, Chief Justiciar of England, whose disgrace in 1232 resulted in his new erection being seized by the Crown. A century later, in 1365-6, consider- able reconstruction of the Castle took place, perhaps amounting to entire rebuilding, and the celebrated William of Wykeham, it is thought, may have been responsible for this, as for so many other royal castles at that time. The plan of the Castle was that of an elongated octagon, but the whole length of the southern enclosing curtain wall with its towers have been involved in a landslip and now lie many feet below their original position. Two of the circular angle Towers remain in fairly perfect condition, and traces still exist of the barbican and its flanking tower. By the middle of the 16th century Hadleigh Castle was already a ruin. It is now scheduled as an Ancient Monument under the appropriate Acts. A quick walk along an elevated ridge of land known as The Saddleback brought the party in about 11/2 mile to Leigh station, where fast trains ensured a speedy homeward journey, after a most enjoyable excursion. The botanists succeeded in noting no fewer than 101 plants in flower or fruit, a very good performance for so late a date ; some of the more interesting plants seen were Erodium cicutarium, Ononis spinosa, Aster tripolium and var. discoideus, Helmintia echioides, Lactuca saligna, Statice Limonium, Verbena officinalis, Chenopodium rubrum, Atriplex patula vars. hastata and angustifolia, A. littoralis var. marina, Polygonum aviculare var. littorale and Lemna gibba. A few of the visitors devoted themselves to noting the birds seen during the walk ; these included Lesser Blackbacked Gull, many Black- headed Gulls, Magpie, Goldfinch, Goldcrest, Jackdaw, Martin, etc.
