Odontoglossum 



blind, which pulls up and down, is most excellent 

 of all. It may be bought under the name of 

 " wooden shading." 



Odontoglots demand as much moisture in the air 

 as can be given, and a great deal at the roots, from 

 March to the end of August. They must not be 

 allowed to dry at any season. I know how difficult 

 it is to pronounce upon the quantity of water which 

 should be given, because the conditions of a house 

 are so different ; but at the same time I am con- 

 scious that some sort of practical hint is necessary, 

 for very much, not to say all, depends on water- 

 ing. There are amateurs of my acquaintance who 

 syringe heavily twice a day from the time when 

 their Odontoglots have gone out of flower till the 

 late autumn, and go through the house carefully, 

 watering-pot in hand, twice a week. I have heard 

 of others who water, with a fine rose, every day, 

 which comes to much the same thing. Such treat- 

 ment is not to be recommended, but it aids us in 

 getting an idea. Plants live under it and flower, 

 usually, but they do not thrive. Not a few rot 

 suddenly by times. It must be observed also that 

 these gentlemen ventilate most freely, and rely much 

 upon their watering to damp the air ; they do not 

 like to splash the walls and floor and everything in 

 the house several times a day, as I advise, in summer.
