 leaves, or tan, every Autumn, and covering the sur- 

 face over with sand or coal ashes, for the pots to 

 stand on ; when these should be arranged accord- 

 ing to their different sizes, without plunging, as the 

 heat arising from the fermenting substances will 

 increase the temperature of the house, and produce 

 a mild congenial heat to the roots of the plants, 

 which will greatly facilitate the growth of the more 

 tender species. The pots remaining unplunged on 

 the bark bed, will not be so subject to have their 

 roots injured with worms, which is always the case 

 when plunged in the bed, and which are very per- 

 nicious to the young roots. During the Winter 

 months, when there is but little sun to dry up 

 the moisture, great care must be taken not to give 

 any of the plants too much water ; it is preferable 

 to give them little, and frequently, as they may 

 appear to require it, than to deluge the pots with too 

 much moisture, in their quiescent state. When the 

 flues, or hot water pipes, are pretty warm, the 

 pouring of water on them will produce a fine steam, 

 very beneficial to the plants, and also obnoxious to 

 the insects, whose depredations should always be 

 kept in subjection. When the Aphis, or green fly, 

 infests the young shoots, recourse must be had to 

 fumigation with leaf tobacco, which appears the 

 most effectual remedy for their suppression. The 

 advantage of a mild, or rather calm evening, should 

 be taken, and the houses well filled with the fumi- 

 gating bellows, which will instantly destroy these 

 noxious depredators. The plants will require to
