2 The Ancient Fauna of Essex. Even among the members of a Naturalists' Field Club there is at times no doubt a tendency to become the unintentional extirpators of some rare plant or insect when the resort of the one or the habitat of the other has been made public in its Proceedings. But there must always be a wide distinction drawn between the true Naturalist and the ordinary collector. I earnestly trust that you all belong to the former type, and, if you collect, you will be careful not to exterminate a species for the mere purpose of obtaining duplicates for exchange. I wish now briefly to refer to the historical records of Epping Forest and the neighbouring area, so far as I have been enabled to gather them. So lately as a.d. 1700 the entire tract between the rivers Roding and Lea was forest-land, the greater part covered with timber. In the Notes to Bowen's Map of Essex (1743) it is stated, "Epping Forest was formerly of very large extent, but its limits were settled and restrained by Act of Parliament (17 Car. I.), according to which regulation it is now about fourteen miles long and ten broad. 'Tis full of game, and well stocked with deer, said to be the largest and fattest in the kingdom." Epping Forest, with the neighbouring forest of Hainault, which was disafforested about thirty years ago, was originally called the Forest of Essex or the ancient Royal Forest of Waltham. It is said to have extended at one time over a very vast district, including in the reign of Henry III. (1228) almost the entire county of Essex; while in the reign of Edward I. (1298-1300) the perambulation, if correct, com- prised lands running down to the townships of Havering, Dagenham, Barking, and other places in the neighbourhood of the Thames. In the reign of Henry II. (1154), the Forest of Middlesex extended from Houndsditch to about twelve miles north of London, and belonged to the Corporation of the City of London. The Forest is described as abounding in Wolves, Wild Boars, Stags, and Wild Bulls. So late as the time of Henry VI. (1485), Wolves were met with
