Connected with this terrace garden, but on the ground level, is a piece of ground laid out in various beds, principally furnished with dahlias. Here is a handsome marble fountain or column, and a well formed sheet of water.

About three hundred yards from this spot is Charlottenhoff, a handsome erection, which is used occasionally as a tea or coffee room. This building is surrounded by numerous walks, and columns with vines trained against them. Ascending a flight of steps, that leads to a point of view looking down upon a fountain, playing with great force. This spot is tastefully laid out, and in very neat order. Several other ornamental erections are placed in these grounds, but to attempt to describe them all would require an actual residence for some weeks. The royal palace of Potsdam is a magnificent building, in the form of a quadrangle. The interior apartments contain numerous objects of interest, which as being highly estimated by Frederic the Great, are particularly pointed out to the stranger. The arm chair which he was in the habit of using, is still in a good state of preservation; I was much pleased with the magnificence of the rooms; the paintings and furniture are very splendid, and in good preservation. The ground attached to this palace consists of a flat surface, extending towards the south, as far as the river Havel, and is laid out in clumps of trees, various walks; the space next the palace is a larger piece of gravel, which is daily used for the exercise of the military. Adjoining it are numerous avenues of horse chesnuts, and busts of ornamental sculpture placed along the first row of trees, as well as some in various other positions. Opposite the south, or principal front of the palace, is an oblong piece of water, in the middle of which is placed a noble group of Neptune and his sea horses, which has a very grand effect, but the water is kept rather low and filthy, which might be easily remedied, as the river Havel passes within a few yards of it. By the edge of the river, in a marshy spot of ground, I observed a large quantity of the Hydrocharis morsus-ranæ (Frogbite,) and Stratiotes aloides, (water soldier,) growing in great abundance.

I should however have observed that the fine marble group of Neptune was much injured by the French army, during the time they occupied Potsdam. In short it is really grievous to see the depredations that were committed by that army on the sculpture about Potsdam and Sans-souci, whilst they resided there. The soldiers for amusement were in the habit of firing musket balls at the different groups and statues.

August 30th. Left Potsdam at eight o'clock in the morning, for the Pfauen Insel, or Peacock Island, where I had appointed to meet Mr. Cuming at nine o'clock. We had to cross a branch of the river Havel to get to the island, which contains a collection of plants and animals somewhat resembling the Zoological Gardens in Regent's Park. I was here more fortunate in finding M. Fintelman at home, than I was at Sans-souci, and having a letter of introduction to him from his uncle, who superintends the royal gardens at Charlottenburg, I found him remarkably attentive, and an intelligent young man. I was here surprised to find the Robinia pseudacacia had attained seven feet in circumference, at four feet from the ground, the branches of which extend over thirty two yards of ground in diameter. I also observed some fine specimens of the oak, which were little inferior to our largest English oaks. The conservatory is an oblong building, about one hundred and twenty feet by forty, and forty two feet high, and consists of several tiers of front sashes, with a span roof, the north side being a dead wall with a gallery for resting in behind it, which commands a full view of the plants underneath.

I was much gratified, by the very flourishing state of the plants, and their remarkable neatness. A very fine collection of the Palmæ, is cultivated in this stove or conservatory, some of which have made a rapid progress in their growth. The Latania borbonica measured twenty seven feet in height, spreading over a space of equal dimensions in diameter. I understood that his majesty the king of Prussia frequently breakfasts in the summer season in this conservatory, under the shade of the palm fronds (or leaves). I remarked also the Pandanus utilis twenty three feet high; the Dracæna Draco, (Dragon Tree) had likewise grown thirty six feet high; Pandanus sylvestris thirteen feet in height, and eleven feet in diameter across its branches; the Bambusa arundinacea, forty feet high; a shoot of this cane, grew seven feet six inches in the course of three weeks; the Corypha umbraculifera, a very magnificent specimen. The Latania borbonica is placed in the centre of the conservatory; the tub in which it grows is completely concealed by planting around it various ferns, and other low growing plants, which are tastefully arranged, and form a nice little stage round the tub, having a very neat appearance, with the walk round it, which shews the palm to the best advantage. Opposite to this spot is a recess in which is placed a small fountain tastefully decorated by ferns that succeed well in a shady situation. There is likewise in this recess, a very handsome marble screen, richly carved and ornamented. The grounds are very judiciously laid out in various clumps of flowering shrubs and summer flowers, and were at this time in full perfection. One of the finest Hydrangeas that I have seen, was in full bloom, and its large purple-blue flowers were very conspicuous. The grass lawn was in a much better state than any other that I had previously seen in Germany, or even met with during my tour on the continent, and the whole garden ground very neatly kept. The island is said to contain about four hundred English acres. The erections for the different animals and birds are judiciously placed, and consist of handsome structures, arranged from two to three hundred yards or more apart; these apartments were kept remarkably clean and in good order. An extensive collection of beasts and birds are preserved in this establishment. The grounds are considerably varied, and some fine views are to be seen from several parts of it, as well as from the top of some prospect towers. The effect of the river Havel, and surrounding plantations at the opposite sides, adds expressive features to this landscape.

After seeing the various objects most deserving of notice, both in the botanical and zoological departments, we proceeded across the river, to the grounds of Prince Charles, still accompanied by M. Fintelman; they were laid out, principally, in the English style, his royal highness being particularly partial to it.

This spot consists of a great variety of surface, with several beautiful vistas, and is really very tastefully planted, and the grounds formed, and kept in very excellent order. The public road from Berlin to Potsdam passes close by the front of the grounds, and there is a low wall, with an invisible wire fence on the top of it, betwixt the road, where the views of the grounds are seen to most advantage. One side of them extends close to the Havel, where a handsome summer house is erected, which commands a fine prospect of Potsdam, the new bridge, and shipping, and likewise the scenery on the opposite side of the river, which is much varied. Under this building are two colonnades covered with creepers, which have a very pretty effect.

On the one side of a hill nearly opposite to this villa, is a new residence erecting for prince William; the views from it must be very extensive, as it is situated on a commanding spot.

We next proceeded to the magnificent edifice called Marmorpallast, or marble palace, which is situated at a very short distance from Potsdam, and close to the margin of the Havel. It is a splendid building, the greater part of which is constructed with marble. The cornice appeared to be about five or six feet deep; it is of white marble, as also is the base above the ground for several feet; the door and window jambs are likewise of the same material. The intervening spaces of the walls are built with red brick. The colonnade at the principal entrance consists of handsome marble columns. The pleasure-ground and gardens attached to it are said to contain two hundred and fifteen German acres of ground, throughout which are dispersed various clumps of trees and shrubs, with extensive walks and rides branching through it in different directions. These grounds are very flat, and have but little variety or picturesque appearance in them. The number of good exotics and New Holland plants is considerable, as well as a very fine collection of healthy orange trees, with some fine specimens of hardy trees growing singly on the grass. I here observed the Juglans fraxinifolia bearing a number of good sized fruit. In the flower garden some good German stocks, then in full bloom. The borders and grass lawn were in a rough state.

We next proceeded to Sans-souci, Mr. Cuming not having previously seen it. I was delighted in having another opportunity of looking round this truly magnificent spot; and being accompanied by Mr. Fintelman, who kindly devoted the entire day in conducting us to the various objects best worth our notice, we proceeded through the grounds attached to Sans-souci palace, and then to Charlottenhoff, the new palace, &c., and were much gratified by the numerous objects of interest we had pointed out to us in the various places that we inspected.
