248 STOCKING AND MANAGING WARDIAN CASES. 



by the appearance of the plants ; the great danger is in giv- 

 ing too much moisture ; the soil then becomes sodden, tha 

 young fronds decay, and the older fronds collect mould. 

 The soil should at all times be moist, but never wet. 



As to general ventilation, when the plants are fully 

 established: The requirements of different plants are so 

 various that no rule of universal application can be given ; 

 flowering plants need the most, ferns and lycopodia the 

 least. 



Light is essential, and a few hours of gentle sunlight are 

 beneficial. The direct rays of a hot sun should be avoided. 

 When the sun is on the case keep it closed, unless the soil 

 has become too wet. Of course dead leaves must be 

 removed, and all kept clean. 



Let us now consider the adaptation of the Wardian case 

 to flowering plants. And we must frankly state that the 

 case does far better for the exhibition and preservation of 

 flowering plants than for their growth. 



If you have a green-house, bring the plants forward there ; 

 as soon as in bloom remove them to the case, sinking the 

 pots in the soil, and they will remain a long time in 

 perfection. 



In the selection of plants those with variegated foliage 

 are to be preferred, as they are gay at all times.
