Barkeria 



granted a plauo tthere they get several hours of 

 sunshine on the hottest day, yet without risk of 

 burning, and where ventilation is free, though the 

 atmosphere be always saturated with damp, it 

 matters little how they be established. But those 

 conditions imply that they shall be close to the 

 glass, and therefore a block or basket is necessary 

 in most houses. 



Differences also may be observed in treatment. 

 Some recommend water twice a day in summer, 

 and once a week at least in winter. Doubtless 

 this answers in their case, but it would be too much 

 generally. One may put it more safely that Bar- 

 kerias should be kept soaking while in strong 

 growth, dried oft' grailually in late autumn, and 

 granted Imt very few waterings through the winter. 

 Under that treatment, indeed, the plants will 

 shrivel alarmingly, but when the moisture is re- 

 newed in spring they plump out and thrust their 

 dainty roots abroad with a corresponding vigour. 

 I presume, in fact, that they shrivel equally in 

 those houses where they are not so thoroughly dried, 

 because there is less moisture in the air ; otherwise, 

 apparently, they would not get sufficient rest. The 

 temperature must not be less tlian 50° in winter.
