quently. Still, if you have no other means 

 of holding, use a stand, but get it as near the 

 window as possible, and slightly turn the 

 plant each day so that all sides will get an 

 equal amount of light. 



Trellis. For training weak-stemmed 

 plants a trellis of some sort is often handy. 

 This may be made from small, square wood 

 stakes, or from wire. Either form is good. 



Wardian case. A Wardian case is prac- 

 tically a greenhouse of small dimensions, 

 say 2x3 X 2^ feet. It is made entirely of 

 glass with a wooden frame. Usually a pitch 

 roof is put on it; the sides of the roof being 

 hung on the ridge pole by hinges so that the 

 inside of the case is accessible. In the 

 bottom of these cases is a zinc pan for the 

 earth. The plants are set in this, watered, 

 and the case closed. The moisture trans- 

 pired by the foliage and evaporated by the 

 soil condenses on the glass and drops back. 

 As a result, there is always a humid atmos- 

 phere in these cases, and but little water- 

 ing has to be done. Where conditions will 

 not permit of the culture of ferns in the open 

 room, they can be grown most successfully 

 in Wardian cases.
