It will be noticed that even the rhizomes purchased in Ger¬ 
many were not in good condition. As these rhizomes were ob¬ 
tained in January, they should have shown an internal green 
coloration had they consisted of the fresh stock harvested in

supply for exportation, at least, is not renewed yearly as it 
should be, but is allowed to accumulate and deteriorate.
