A further pleasure-ground, with the finest trees and many beautiful surprises,--among others pretty children's gardens, and a grass garden in which all sorts of gramineous plants were cultivated in little beds, forming a sort of chequer-work,--led to the Aviary. This consists of a large place fenced in, and a cottage, with a small pond in the centre, all dedicated to the feathered race. Here the fourth or fifth attendant awaited us, (each of whom expects a fee, so that you cannot see such an establishment under some pounds sterling,) and showed us first several gay-plumed parrots and other rare birds, each of whom had his own dwelling and little garden. These birds' houses were made of twigs interwoven with wire, the roof also of wire, the shrubs around evergreen, as were almost all the other plants in this enclosure. As we walked out upon the open space which occupies the centre, our Papageno whistled, and in an instant the air was literally darkened around us by flights of pigeons, chickens, and heaven knows what birds. Out of every bush started gold and silver, pied and common, pheasants; and from the little lake a black swan galloped heavily forward, expressing his strong desire for food in tones like those of a fretful child. This beautiful bird, raven black with red feet and bill, was exceedingly tame, ate his food 'chemin faisant' out of the keeper's pocket, and did not leave us for a moment while we were sauntering about the birds' paradise, only now and then pushing away an intrusive duck or other of the vulgar herd, or giving a noble gold pheasant a dig in the side. A second interesting but imprisoned inhabitant of this place was Hero, an African crane, a creature that looks as if it were made of porcelain, and frequently reminded me in his movements of our departed dancing Ballerino. The incident of his history which had gained him his lofty name was unknown to the keeper. The park, which is four German miles in circuit, does not consist merely of heath or meadow-land and trees, but has a fine wood, and also a very beautiful part fenced in, called the 'Thornery,' a wild sort of copse intersected with walks and overgrown with thorns and brushwood; in the midst of which stands a little cottage with the loveliest flower-garden.
