The Evils of Deep-drainage from the Naturalist's point of view. By M. C. Cooke, M.A., LL.D., A.L.S., &c. Many of those who are interested in the study of Natural History, resident in and around the metropolis, have long been accustomed to visit Epping Forest in pursuit of that study, and have often been delighted with the numerous forms of life which that wild and natural haunt has furnished to them. They are nevertheless alarmed lest the Conservators should be induced to follow the baneful example of the custodians of other localities, and resort to deep-drainage, and other so-called improvements, whereby the natural character of the Forest will be greatly injured, and certain animals and plants irretrievably exterminated. Under this feeling, they are induced to remind all those who control the destinies of the Forest that there is no apparent necessity for reducing the humidity of the soil in the interests of the ordinary visitors to the Forest; that any alteration in this direction must, of necessity, by altering the conditions under which they have long flourished, be fatal to all the flowering plants which only grow in moist situations, of which many are now natives of the Forest. Artificial disturbance of these natural conditions will not only destroy the plants themselves, but as these plants are many of them the favourite food of certain species of insects, the disappearance of the food- plants will also be accompanied by the extermination of the insects feeding upon them; such insects, in most cases, refusing to subsist on other plants. The result of such artificial disturbance would therefore be to change the character of the fauna and flora of the Forest, which it was hoped would be maintained "as nearly as possible in its natural condition." More serious consequences are apprehended from any diminution or abolition of the boggy pools, ponds and ditches, which are now numerous in the Forest. It is calculated, at a low estimate, that not less than 500 different and distinct species of microscopically minute animals and plants inhabit the stagnant waters collected in the small pools and boggy places in the Forest. In these days, when so many persons confine their biological studies almost entirely to these minute organisms, it is a subject of general regret that almost every year they are compelled to go farther and farther from London in search of the subjects of their investigations. The abolition of waste ground and the drainage of all stagnant pools, in the interests either of the builder, the cultivator of the soil, or often through lack of special knowledge on the part of the " Conservators of open spaces," have extirpated many of the most interesting organisms, which but a few years ago were abundant. Under these circumstances, it is but a small thing that the biologists of London and its vicinity ask of the Conservators of Epping Forest, but to them it is one of vital importance as far as the utility of the Forest is concerned. They ask that the Forest should be maintained literally as much as possible in its natural con- dition ; that all drainage systems, which tend to alter completely the natural conditions of the Forest and its surroundings, may be abandoned; that no attempt be made to " improve " such places as Wanstead Flats, by reducing, limiting, or filling up the pools, and thereby " improving " some hundreds of living species of animals and plants off the face of the
