THE COMMON POLYPODY IN ESSEX. 289 The testimony of otheis is to exactly the same effect. Thus,. Mr. Shenstone writes me :—"Our Essex woodlands have been largely cleared of the Male Feins, Lady Ferns, &c., which were fairly abundant in the woods near Colchester in my early botani- cal days." Further, Mr. E. E. Turner, who has an unrivalled knowledge of the flora of the Coggeshall district, writes me that the Hart's Tongue (Scolopendrium vulgare) "was fairly common there when I was a boy, but I do not remember having seen a specimen for years." As to the main reasons for the disappearance of these ferns from their old localities in the county, there can be no doubt whatever. That disappearance is due in part to more intensive cultivation and in part (as to those species which grow in bogs) to the steady draining of bogs ; but, more than all else, it is due to gradual eradication by trippers, trade-collectors, gardeners, and others, who dig up roots for removal to their gardens, where, more often than not. they are neglected and quickly die. Yet one may well wonder whether there is not some other cause also at work—at least in connection with the Polypody, which, though still common, has decreased very markedly in- deed in recent years. When I was a boy, this fern was certainly immensely more abundant in Essex than it is now. In the district already referred to, including the whole of the Roothings and even beyond Dunmow, it was then very common on rotting stumps and among the roots of hedges growing on the banks of ditches, both by the roadside and among the fields. I have in my diary not a few notes to this effect. Thus, on 20th December 1875, I noted it as "immensely abundant—more so than I have ever seen it anywhere else—"on the road-side banks between Chignal St. James and Dunmow. Again, on 30th December 1876, I noted it again as "immensely common" on certain roadside and other banks at Lindsell, together with its varieties acutum and serratum, and with fronds which were not only bifid them- selves, but had also some of their pinnae bifid.4 At the same time and place, I also saw it growing on the crowns of pollarded trees, and noted explicitly that "the top of one oak-tree was covered thickly by one root two yards square." Again, on 18th 4 Specimens gathered on this occasion are preserved in my herbarium, now in the Club's Museum.
