are excessively rich. One must have been present at the assemblies in the 

 gardens and banqueting-rooms of some of the richer nobles of Vienna and 

 Moscow, occasionally thrown open to the public, for whom the finest music 

 and provisions of every kind, without limitation, are provided, to understand 

 something of the enjoyments which such institutions are calculated to afford 

 in this country. — Cond. 



The Garden of the Horticultural and Botanical Society of Manchester is 

 proceeding apace. The ground in all is 15 acres, chiefly of sandy soil, but 

 in part clay. The east, west, and north walls are built; there will be about 

 100 yards of glass, besides pits and frames. Two lodges are built, which, 

 I am afraid, you will not like ; and, unfortunately, the main entrance to the 

 garden is from the north (on the Chester road), which you have shown in 

 your Encyclopedia of Gardening to be always bad. — Y. H. March 2. 1830. 



The Weeping Ash of Wilson's Nursery at Derby, of large dimensions, and 

 nearly half a century old, has been purchased by the Duke of Devonshire, 

 and removed to a conspicuous situation at Chatsworth. The tree was re- 

 moved on a machine similar to that used by Sir H. Steuart, constructed by 

 Messrs. Strutt of Belper, and under the direction of Mr. Paxton, the duke's 

 head gardener. The weight of the tree was estimated at from 7 to 8 tons, 

 and the distance to which it was conveyed is 28 miles. We are not informed 

 whether the roots were previously prepared by cutting ; but, from the sub- 

 ject not being mentioned in the very long account of the operation given in 

 the Derby and Chesterfield Reporter, April 15., we should conclude not. We 

 are happy to hear of the duke's taste and liberality, and should be still fur- 

 ther gratified to learn that he had established, or would establish, at Chats- 

 worth, a complete arboretum, allowing sufficient space for each tree to attain 

 its full size, and introducing every hardy tree which could be procured in 

 the London nurseries. The expense would not be greater than removing 

 half a dozen such trees as the one above mentioned. — Cond. 



Heating Hot-houses by Fowler's Thermosiphon (Vol. V. p. 453.). — A 

 printed letter has been sent us on this subject, of which we subjoin an ex- 

 tract : — " The house, a plant stove, is 60 ft. long ; the vertical height 15 ft. ; 

 and the cubical contents, including an excavation for growing the plantain, 

 banana, and other choice stove-plants, above 10,000 ft. I generally allow 

 about an hour, with a brisk fire under the boiler, before I set the machine 

 to work : I then remove the siphon plugs, and, almost instantly, the hot 

 water rushes up the ascending leg of the siphon, which destroys the pre- 

 existing equilibrium very considerably, and causes a rapid flow of hot water 

 from the furnace into the main-pipe on the ground-floor ; and, in the space 

 of a few minutes, the whole line of main-pipe, as well as the siphon, is sup- 

 plied with hot fluid. When I find that the atmosphere of the house has 

 risen to the maximum I want, I let the fire be stayed with wet ashes : after 

 this px-ocess, little or no attendance is required. The fuel I chiefly use is 

 either small coal or culm, mixed with ashes. The machine has often conti- 

 nued working, for upwards of 14 hours, without any addition of fuel ; namely, 

 from six in the evening till eight the next morning : the temperature at night 

 being 79° ; in the morning, 68° ; the thermometer in the open air, at the 

 same time, 28°. I have frequently worked it, for several days together, 

 without any attention being required to the filling-cock ; the motion of the 

 fluid denoting the perfect action of the machine, and showing more or less 

 rapidity, according to the management of the fire. The air is salubrious, 

 and highly congenial to vegetation, having neither an overplus of aridity nor 

 superabundance of humidity. The machinery part answers perfectly well ; 

 the operation is simple, and the management easy : not the least alteration 

 has been required ever since its commencement, and it is not likely to get 

 out of order, or require repair. I have seen several steam-machines, level 

 hot-water apparatus, and many different constructions of brick flues, for 

 causing artificial heat, but am decidedly of opinion that the thermosiphon
