The WILLOW-TREE, one of the most striking and clever of the water-works, is a weeping willow, about twenty feet in height, entirely formed of copper and lead, and coloured in imitation of a real tree. It stands in a charming little circular dell, overhung with forest-trees, and surrounded by banks and rockeries covered with luxuriant ferns and other plants, itself rising from a central rock-work, around which runs a path. At the entrance to this little dell are a vase and fountain, and at the opposite side is a leaden statue of Pan, holding in his hand the Pandean pipes, and having a goat at his feet. From each leaf and stem of this remarkable tree, the water, when turned on from a small hidden cave in the rock in front, rushes out in a rapid stream, and thus forms a novel kind of “shower-bath” to any luckless visitor who may happen to be beneath it. [Illustration: _Part of the Rock-work._] At the same time, a number of jets rise up from hidden pipes all around the dell, and these streams being directed angularly upwards towards the centre, while those from the tree fall in all directions downwards, there is no way of escape without being caught in the heavy shower. Of this tree we give an engraving from a photograph taken specially for the purpose, with others of our illustrations, by Mr. George Green, of Worthing, an eminent photographic artist, whom we specially engaged for these Chatsworth views, and whose skill deserves high commendation. Near the Willow-tree, passing onwards towards the grand conservatory, is a rocky archway of wondrous construction, and a little beyond this a “rocky portal”—an immense block of unhewn stone, turning upon an axis with such ease as to be moved with the pressure of a single finger. Passing through this portal, one of the next most striking objects is a perpendicular rock, of great altitude, down whose face a stream of water is for ever falling, and this water supplies some charming little lakes filled with aquatic plants, in whose windings and intricacies the botanist and lover of nature might revel for hours.
