 We may here remark that much more harm is done to all greenhouse 

 exotics by the application of too much fire heat, than by the opposite 

 extreme. A narrow shelf runs round the house, on which the smallest 

 plants are to be set. 



In regard to the height of a CameUia house, that must be determined 

 by the size of the plants intended to be cultivated ; and as it cannot be 

 conveniently altered after the first erection, it will be better to elevate the 

 platform to a sufl[icient height to suit the plants while they are small, and 

 to lower it progressively as they advance in height. 



PROPAGATION AND TREATMENT WHEN YOUNG. 



The Camellia is propagated by cuttings, seeds, budding, grafting, inarch-

 cuttings, layers, and seeds ; the two former, for stocks on which to bud or 

 inarch the better kinds, and by seeds, with a view to procure new 

 varieties. 



In propagating by cuttings, the month of August has been found to be
