with its brilliant blue flowers was to me pleasingly conspicuous; but the diligence, although slow, was yet too fast to allow me time to procure a few specimens. On passing the magnificent palace of Charlottenburg, I was much struck with its extensive appearance, and fine park, leading from it all the way to Berlin, through the Brandenburg gate, and along the Linden or lime tree walk, to the splendid university, armoury, museum, and other large buildings, and handsome bridges, with the statues placed on them, its magnificent palaces, which all appear in view from the diligence, by this the Hamburgh line of road, and to the eye of a stranger has a grand effect, giving him the idea of a great and noble city, by seeing so many magnificent buildings immediately as he enters the town. Within a few stages of Berlin I met with Mr. Parker, Bookseller, from Oxford, travelling in the main Diligence, where I joined him; on our arrival in the city, we took up our abode, in the St. Petersburgh hotel, after breakfast we separated, he in search of books, while I went to visit the Royal Botanic Gardens at Schoenburgh, which are situated about three English miles from Berlin, where I was much gratified by the many fine specimens of plants that I saw. Having letters of introduction to M. Otto, from Sir W. Hooker and Dr. Lindley, as well as from his old friend Mr. Hunneman, I experienced the greatest attention from him, he took great pains in pointing out to me the various new and curious plants in this extensive collection. There were some very fine species of Palms, in great beauty, nearly reaching to the top of the hothouse, which is about thirty feet in height. The Latania borbonica, was particularly fine, and had attained nearly twenty five feet in height, its foliage or fronds extending from ten to twelve feet on each side from its stem. The Gomutus saccharifer, had also reached to the height of twenty five feet, and numerous other choice specimens of the Palmæ, were in an equally healthy and luxuriant state, and of little less dimensions than those specified. The Aristolochia brasiliensis was particularly fine, covered with long beautiful speckled flowers, that extended over a large part of the rafters. Many new and fine specimens of the Gesneras were also in flower; they appeared different from any that I had previously seen in this country. Some of the Melaleucas; in the conservatory had grown to the height of nearly forty feet; the Magnolia grandiflora, which requires the protection of the conservatory during the winter months was now covered with fine large flowers. Numerous other species of New Holland plants, had grown to an amazing height in the conservatory.

The hothouses in this garden are placed in several separate ranges, and are very substantially built in comparison to our erections in England. The quantity of timber employed in the rafters is immense, but giving them a very heavy appearance; yet I have rarely met with a more healthy collection of plants anywhere; they may be considered the most extensive on the continent of Europe. In short, I never before saw so many plants cultivated in pots. The numerous species of New Holland and Cape genera were quite astonishing, as well as the hardy and Alpine species. As to the Cacteæ, there can be no hesitation in saying that the collection in these gardens of this curious tribe of plants really comprises the most beautifully grown specimens that I have ever seen; the different species that have grown to a considerable size have a very interesting appearance, particularly the Mammillaria and Echinocactus tribes; with their numerous spines and angles, they form a pleasing object either in or out of flower. M. Otto has long been celebrated for his ardent love to this curious tribe of plants, and he certainly has succeeded in forming a valuable collection. The species of Ferns in these gardens are likewise very numerous, and there are many very fine specimens amongst them, which have grown to a great size. I could not but admire the very tasteful manner in which the Cape and New Holland plants were arranged out of doors in the summer months, and which were neatly plunged to the rims of the pots, to prevent them from being blown about by the wind. The Bignonia radicans formed a very prominent object against the end wall of one of the hothouses; the luxuriance and brilliancy of its flowers far surpassed any that I had previously seen. A fine specimen of the Laurus indica, which must have been fully twenty feet in height, was standing out of doors, and obliged to be cut down, as it was getting too high for the house in which it stood in the winter season. The Robinia Pseudacacia, inermis and tortuosa were both splendid trees, which ornamented the grass lawn. The Magnolia acuminata, also a beautiful specimen, as well as the Quercus palustris, and rubra; both had attained a great size, and were handsome trees, as well as several other species of this genus. Mr. Otto having kindly requested Mr. W. Brackenridge, who had been for some time from Scotland, residing in the neighbourhood of Berlin, and was then employed in the Botanic gardens, to accompany me the following day to such places as he considered most deserving of notice, I arranged with him to be ready betwixt six and seven o'clock in the morning, to proceed to the different gardens.

August 27th. We started at seven o'clock in the morning, to the royal gardens at Charlottenburg palace, which are situated about four English miles from Berlin. The grounds attached to this royal palace, are said to contain four hundred English acres, laid out with various walks, clumps of trees and shrubs, as well as several pieces of water, embracing some very fine views from different points notwithstanding its being a flat surface, but it is much diversified by trees, bridges, and sheets of water that intersect the lawn. There are several bridges leading across the stream to the most ornamental and picturesque parts. The palace is also seen to great advantage from several points in the grounds. A very fine specimen of the Quercus palustris was in great beauty on the grass. I also saw some very large trees of the Populus alba, which were considerably larger than any tree of this species that I had previously seen. M. Fintelman, the superintendant of the royal gardens, pointed out to us a very complete Fructiferum, that he had lately formed in these grounds, comprising a collection of all the hardy fruits. Nearly adjoining to the palace, is a very handsome little flower garden, lately executed for the growth of the dwarf flowering perennials and annuals. I was much pleased by an arbour formed with the different species of Cape and New Holland plants, that are rather flexible in their growth; the pots in which the plants grew, were all plunged round the back, the branches tied closely to it and thickly covered, producing a great variety of foliage, and pleasing effect, and having the appearance of growing there permanently throughout the season. Opposite to this Botany Bay, or Cape Arbour, is a pretty summer house, which is chiefly composed of reeds. In the centre of the flower garden, there are various posts with iron rods extended from them for the training of creepers. Again, at the extremity, is an artificial grass bank, considerably elevated above the flower beds, planted with the dwarf china rose, which has a very good and natural effect. The orange-house is an oblong building, of great length, with opaque roof and backwall, upright lights only in the front, completely covered with grape vines, having a very fine crop of fruit all over them. The orange trees were all in excellent health, some of them bearing separately nearly two hundred fruit; there are about three hundred of these trees cultivated here. I also saw a fine variety of Dahlias, and various other beautiful flowering plants in great perfection; these Dahlias are fully as good as any I had seen in England; great attention is paid
