On the highest part of the Forest Ridge in Sussex, where the soil is sandy and covered with heath, fern, and fir trees, there never seemed to be any rooks. These birds, so very characteristic of the country, appeared to be almost absent over several miles. They went by sometimes, sailing down into the vale, but never stopped on the hill, not even to walk the furrows behind the plough. This would seem to indicate a remarkable absence of the food they like, for it is very rare indeed for a piece of ground to be fresh ploughed without rooks coming to it. There were rookeries beneath in the plains where the elms and beeches grew tall, but the birds never came up to forage. Crows could be found, and stopped on the hill all the year. Wood-pigeons, like the rooks, went over, but did not stay. Starlings were not at all plentiful; blackbirds and thrushes were there, but not nearly so numerous as is usually the case; fieldfares and redwings drifted by in the winter, but never stopped. Slow-worms lived in the sand under the heath, and lizards, but no snakes and only a few adders. Inquiring of an old man if there were many snakes about, he said no; the soil was too poor for them; but in some places down in the vale he had dug up a gallon of snakes' eggs in the 'maxen.' The word was noticeable as a survival of the old English 'mixen' for manure heap. Swallows, martins, and swifts abounded; and as for insects, they were countless--honey-bees, wild bees, humble-bees, varieties of wasps, butterflies--an endless list. So common a plant as the arum did not seem to exist; on the other hand, ferns literally made up the hedges, growing in such quantities as to take the place of the grasses. There was, too, a great variety of moss and fungi. The soil looked black and fertile, and new-comers thought they were going to have good crops, but when these failed they found, upon examining the earth, that it was little more than black sand, and the particles of silica glittered if a handful were held in the sun. Such a sand would give the impression of dryness, instead of which it was extremely damp--damp all the year round.
