152 HISTORY AND GEOGRAPHY OF TREES. PARTI. 



planted with Pinus Cembra, so distributed as to resemble a native forest. 

 Baron Hake, at Ohr, near Hainelen, on the river Weser, has formed part of 

 a forest on a hill (Ohr berg) into a park, in which some American trees grow 

 perfectly well : the soil is a sand}- loam. There are, also, many large American 

 trees in the garden of Baron Steinberg, at Bruggen, on the road from Han- 

 over to Ernbeck. At Eldagsen, a small village about four miles from Han- 

 over, there are many large trees, which were planted about the same time as 

 those at Schwcibber. 



In Wurtemberg there are good collections at the Palace of Rosenstein, and 

 in tiic royal nurseries, but scarcely any evergreens. The Palace of Solitude 

 (at one time so celebrated for its gardens) is surrounded by a natural forest, 

 which extends many miles in every direction; the trees are chiefly beech, oak, 

 and the trembling poplar, some of which have attained a great size. (See 

 Encyc. of Gard., edit. 1835, p. 158. to p. 169.) 



In Baden, at Carlsruhe, there was a very good collection under the care of 

 the late excellent M. Hartweg, author of Hortus Carhruhamis ; this collection 

 is still in existence under the care of M, Held, and has since received occa- 

 sional additions. There is also a very good collection in the celebrated garden 

 of Schwezingcn ; which, with all the most remarkable gardens of Germany, will 

 be found de'scribed at length in the last edition (1835) of our Enct/chpccdia 

 of Gardening. At Donaueschingen (the source of the Danube) there is 

 a tolerable collection, and some specimens of abies, populus, and lirioden- 

 dron, of considerable size. In the Black Forest, w hich surrounds this place, 

 are the largest oaks and silver firs in Germany. In 1828, we spent an entire 

 day examining and admiring these noble trees, many of which we estimated 

 at upwards of 100 ft. in height. All the trees and shrubs enumerated above 

 as enduring the open air at Vienna, without protection during winter, do so at 

 Carlsruhe ; with the following additional species, which have been pointed 

 out to us by M. Hartweg, son of the late director of the grand-ducal gardens ; 

 a highly educated young gardener, now in the employment of the London 

 Horticultural Society.

In Hesse Casscl, the garden of Wilhelmshoe, at Cassel,contains a good collec- 

 tion, chiefly planted within the last 20 years ; but some of them have been 

 planted 60 years. From the particulars with which we have been obliged by the 

 director of the garden, M.Claus, we find that the tulij) tree here, 60 years planted, 

 has only attained the height of 20 ft. ; and the ailantus, 60 years planted, is 

 imtlcr 30 ft. The only evergreens of which we have had returns are, the com- 

 mon pines and firs, and C'uprcssus <hyuidcs. 



In Nassau, in the Grand-Ducal Botanic Garden at Bicbrich, there is a good 

 collection, distributed thinly all round the margin of the garden; and, this 

 garden being of very gi'eat length in proportion to its breadth, the space 

 afforded to each tree is such as will enable it to attain a very considerable 

 size. A catalo'Uie of this garden, accompanied by a plan, was published in 

 1831. We may remark here that the names in this catalogue, as in those ot 

 most German catalogues of moileru date, generally correspond with the names 

 in the catalogue of Messrs. Loddigcs; the reason is, that the collections 

 which have been formed in Germany, during the last 50 yeurs, have, for the
