552 Summary Viexv of the Progress of Gardening, 



when they are moderate, with the shelter of a wall ; but all those 

 which do, at least as far as our information goes, are found 

 beyond 33° of south latitude : where, on the more elevated 

 parts of the country, snow often lies for weeks, and ice is fre- 

 quently met with of from a sixteenth to an eighth of an inch 

 in thickness. Most plants from the Cape of Good Hope are 

 more tender than the New Holland plants, although indigenous 

 in the same latitude ; but the reason is, the plants from the Cape 

 ot Good Hope are chiefly from the immediate vicinity of Cape 

 Town, which, with the exception of Table Mountain, lies low, and 

 hence the mildness of the climate and tenderness of the plants. 

 In general, whether we take the northern or the southern hemi- 

 sphere, we must look either to high latitudes, or high elevations 

 and low latitudes, for plants which will endure the open air in 

 Britain. 



In the Hortus Brita7inicus, and in similar catalogues, the young 

 gardener will find one country mentioned as the native place of 

 each particular species. This is all that could be done in the re- 

 stricted limits of a catalogue, and is, so far, of great use; but, if 

 it could be accomplished, the entire range of the plants, both 

 geographically and physically, ought to be made known. This 

 point, we think, ought to be attended to, in the naming of all 

 species in botanic gardens ; at all events, to a greater extent 

 than it is at present. For example, the elevation in feet, and 

 the latitude in degrees, might often be given, in addition to the 

 name of the country, and such words as woods, meadows, 

 marshes, &c., might often be introduced. To stimulate young 

 gardeners to acquire this kind of knowledge, we recommend all 

 their employers, and others, who ask them the name of any 

 plant, to ask also for its native country, and the kind of habitat 

 in which it is found. 



Among the inventions of the year, more or less applicable to 

 garden purposes, Joyce's stove for producing heat without smoke, 

 and Dr. Arnott's stove for regulating the consumption of fuel, and 

 preventing the iron casing of the stove from ever being heated to 

 a higher degree than the temperature of boiling water, stand 

 conspicuously forward. Joyce's stove, of which notices will be 

 found at p. 57., p. 95., and p. 302., when first made public in 

 December, 1837, created an extraordinary sensation, from the 

 products of combustion containing, to all appearance, no carbonic 

 acid gas and no visible smoke : the vapour which escaped from 

 it was also found to be tasteless. In consequence of these pro- 

 perties, it was thought that this stove might not only be employed 

 in plant-houses, but even in living-rooms, without the use of 

 chimneys : and it was considered particularly adapted for small 

 rooms or cabinets having no fireplaces ; for carriages ; for 

 water-closets ; for occasional use in bed-rooms ; and, as the
