As soon as the frosty nights are over, the houses are generally stripped of the sashes, and the trees and fruit left fully exposed to the sun and weather, while the fruit is maturing; but such fruits as are wanted at an early period, are of course not thus exposed. I here observed various trees of plum, cherry, and apricot, thus treated, a more congenial mode of treatment, than by having recourse to pots or tubs, as is in general practised in this country, especially where there can be houses spared for this purpose, as the trees will get established in the ground, and be enabled to produce a more abundant crop and larger fruit than if their roots were confined to a small space for nourishment. I also saw here a great quantity of very fine melons, all trained over moss, and at this season these also were exposed to the weather. The appearance of the fine terraces in front of Sans-souci Palace, gave me more gratification than anything of the kind that I had previously seen. This palace, originally erected by _Frederic the Great_, is now a favourite summer residence of the Crown Prince. It is situated so as to command a most beautiful view of the surrounding country, with six tier of terraces in front of it, each terrace falling about twelve feet under another towards the south from the palace. Along the top are flower borders and broad gravel walks, with a row of very fine orange trees placed along the edge of the gravel walk on each of the terraces, which give them a magnificent appearance. Against these walls are trained principally grape vines, provided with a frame in front for covering them with glass; peaches and apricots are likewise here grown.
