1 5. On manuring Fruit Trees. 

 Some trees over-nianiired having died, a prejudice was 

 created against the practice; and this short paper, which is 

 chiefly a quotation from Christ, is to show that it is useful in 

 moderation. 



16. Notes on the Botanic Garden of the Prince de Salm-Di/cIc, xvith 

 some Ideas on prixmte Botanic Gardens in general. By M. Funke, 

 Garden-Director at Sahn-Dyck. 



M. Funke recommends private persons wlio form botanic 

 gardens to set out with some definite object in view; and this, 

 he thinks, ought to be the cultivation of only one or twofiimi- 

 lies, such as Camellm, ^'ster, jErica, 7?osa, &.c. This, he 

 says, would enable each garden to excel in some one parti- 

 cular thing ; and he cites, as examples, the garden of Her- 

 renhausen, near Hanover, which is celebrated for ericas ; that 

 of the Pfaueninsel, for georginas ; that of the seedsman Dreys- 

 sig, near Erfurt, for stocks, &c. By this species of what he 

 calls monocultural gardens, he says, we should produce more 

 monographical botanists, such as Willdenow, DecandoUe, 

 Haworth, &c. A general collection of plants, he thinks, is 

 only necessary in those gardens which are kejit for public 

 instruction. The monocultural garden of Salm-Dyck, we are 

 informed, was, from the first, intended to be devoted to only 

 two or three orders and families of plants ; and, in consequence 

 of confining itself to certain genera of succulents, it has now 

 the finest collection of them in the world. The genus ^'loo 

 in that garden consists of 121 species and 50 varieties; among 

 which are plants of the A'\qq ferox and abyssinica, 8 ft. high, 

 which attract the attention of all strangers. Tiiere are ] 7 species 

 and varieties of Agave, 13 of YiiccGy 33 of Crassula, 18 of jSeni- 

 pervivum, 10 of Caciilia, 40 of £uph6rb/V/. Of the Cacteae, 

 there are 10 Mammillariic, 12 Mclocacti, 83 Ccrei, 5 Ilhip- 

 salides, 3 Epiphylla, 4 Peruski^r, and 1-5 Opuntito. Of Mesem- 

 bryanthemum it contains 228 species and 16 varieties, and 

 99 Stapcli<^c. The above-mentioned sorts increase from year 

 to year; and make, with the addition of the i'^icus and Scita- 

 mineoc, the families which are cultivated in houses. In the 

 open ground, the collections of /Rosacea', Coniferai, and Lef^u- 

 minoste are very perfect, and are grouped systematically 

 round the castle, /ridea^, Labiata*, i^anunculacea, and the 

 genus Piiionia of which there are at present 80 species and 

 varieties, are also cultivated. Though the botanic garden at 

 Salm-Dyck is confined to the orders and famihes mentioned, 

 yet, in the pleasure-ground and jiark scenery, all the more 

 ordinary, and even the more rare and expensive, showy flowers, 

 shrubs, and trees, are introduced.
