258 ON THE CULTURE 



the glasses are first taken off the pots, to sprinkle 

 the plants with water, and immediately dust them 

 with a little snuff or tobacco-dust, which, being 

 put into a puff, or small piece of gauze, may be 

 thrown upon them with great ease ; a very small 

 quantity will prevent those insects from injuring 

 the plants. This method will also secure other 

 young and tender plants, kept in hot-houses, from 

 the like accident. 



By the end of August the seedling Pines will 

 be grown to a proper size for transplanting, when 

 they should be put into small pots, filled with the 

 same mould recommended for crowns and suckers ; 

 and from that time their treatment requires no 

 difference from that of the others. 



On raising the Fine by Crowns. 



The crown is perfected at the time when the 

 Pine-apple becomes quite yellow - 9 therefore the 

 crowns of such fruit may be planted as soon as 

 taken off: but if the fruit be cut green, as is 

 practised by some persons with the Queen Pine, 

 or if only the top of the fruit be green when cut, 

 as is the case frequently with the Sugar-loaf kinds, 

 (even when the principal part of the fruit is 

 thoroughly ripened), then it will be necessary to 

 let the crowns of such fruit lie a few days after 

 they are taken off, in a shady part of the hot-house, 

 in order to give them that degree of maturity to 

 which nature was not allowed to conduct them. 



Where there is convenience in the hot-house,
