Plants so originated are sometimes permitted to grow on till they flovrer, 

 when, if the variety be considered not of smncient merit to be kept as 

 such, they may then be used as stocks on Tvhicli to bud or inarch the 

 other good kinds. CameUia stocks can never be too large ; for if they 

 Ttete even several feet high and furnished Trith several branches, each of 

 these could be operated upon, and consequently a large plant woidd be 

 produced in a short time. 



It is rarely that any shade of difference foUovrs plants originated from 

 -seeds, unless artificial fecundation has been stiictly attended to. 



PROPAGATION BY GRAFTING, 



Is very frequently adopted, particularly when the sorts intended to be 

 increased do not aheady exist in the same collection. This process is 

 best accomphshed when done in spring, about the period vrhen the plants 

 begin to grow. The kind of grafting most generally practiced is side- 

 grafting, which is one of the most common in use, and therefore requires 

 uo elucidation, fiuther, than as the stocks are often weak, clay should not 

 be used, as the quantity necessary would be too weight^" for the stock to 

 carry. A httle fine moss, kept rather damp, will be a good substitute, 

 and the grafting wax of the French may be here used to advantage. It 

 tends considerably to insm^e success in tliis process, if the end of the graft 

 or scion be left a few inches longer than where the union is intended to 

 take place, so that its end may be immerged in a phial of water, or stuck 

 into a smaU potatoe, or turnip. From either of these soiu'ces the graft 

 will derive nourishment until it is supplied fi'om the stock. 



Side grafting is so called from being pertbrmed on the side of the stock, 

 and differs httle from whip, or tongue grafting, which latter is that in 

 general use in nm'series upon plants generally. In side grafting, the bark 

 and a httle of the wood of the stock is taken off in a slanting dhection, 

 the lower end of the scion is also cut, so as to fit the part as nearly as 

 possible, they are then brought together, tied fast with bass, and clayed,, 

 or mossed over. 



CameUias, like most other woody plants, may be also propagated by 

 several other modes of grafting, of wliich about seven or eight varieties 

 are practised in this country. The French have carried this matter much 

 farther, for we find the late Professor Thouin has described about fortv
