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 surface of the petals faster 

 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 entirely 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.
