608 THE GREEN-HOUSE [NOV. 



every mean should be used to expel humidity, or 

 foul air ; such as clearing the outsides of the pots 

 of green mould, and stirring the surface of the 

 earth with a stick, as frequently noticed before; 

 keeping the walks and floor dry by frequent mop- 

 ping, if pavement, or by raking, if sand or gravel. 



Of turning round the Plants to the Sun. 

 This matter is not so important at this time, per- 

 haps, as in spring, on account that the plants are 

 not now making many shoots, or stretching so vi- 

 sibly towards the sun, as at that season. Yet it is so 

 far necessary to turn round many plants, as that 

 they may be perceived to bend even their leaves 

 towards the light, although they be not in a grow- 

 ing state'. Such should therefore be carefully turn- 

 ed round towards the sun, once or twice in the 

 course of the winter, that they may take more na- 

 tural shapes, and that their leaves may hang or 

 spread the right way, regularly on each shoot. 



Care of tender Plants. 



As the weather becomes severe, it will be proper 

 to secure many tender plants against accidents, by 

 placing them on the crib-trellis above the flues, 

 near to the furnace, or in the hotter parts of 

 the house. The falling of very severe frost, when 

 not suspected, and when the furnace is perhaps not 

 sufficiently charged over night to repel its effects, 

 might ruin many plants, if this precaution be not 

 taken.
