A use for Orchid Pseudobulbs—We have received from a corre- 
spondent in Grand Cayman, British West Indies, a pseudobulb of 
Schomburgkia Thomsoniana which is used for making tobacco pipes 
in the island. The pseudobulbs are about 9 inches long and make

anana.” 
In another species (S. tibicinus) a native of Honduras, the pseudo- 
bulbs are between 1 and 2 feet long and quite hollow and smooth

whence it is called the cowhorn orchid. At their base too there is 
always a small hole and masses of ants and other insects take 
advantage of it in constructing their nests.
