water, it will be found that the latter will keep fresh and sweet the longest. The 
explanation is only in the greater humidity. In the former case, the air of the 
room being too dry, evaporates the water from the surHice of the petals Hister 
than the stem can supply, while in the latter the flower is completely surrounded 
with all it needs. 
Observing this principle then in your cut flowers or bouquets, if you will take 
care to place them in pans of water, or sand and water, and then cover with bell 
glasses, they will have a humid atmosphere entiicly to themselves, retain their 
freshness for double the length of time, as they would if exposed to the dry air 
of the sitting-room. 
The Wardian Case then, in principle, is not only the most practical in opera- 
tion, but beneficial in results.
