not acquire a vivid green color, but remained pale and yellowish ; they 
did not wither until the usual time late in autumn. The roots continue 
were vigorous, very Jong and beset with numerous fibrils and buds. In 
the funnel tube the roots made a perfect tissue of fibers. In the dr 
earth of the funnel the roots were less extensively developed, yet exhibited 
some juicy buds. The stem and the young axillary leaf-buds were also 
full of sap. The water-roots being cut away, the plant was put into gar- 
den soil and placed in a conservatory where it grew vigorously, and in 
May bore two offshoots. 
The experiment makes it quite certain that plants extend a portion of 
their roots into the subsoil: chiefly for the purpose of gathering supplies 
of water. 8. W. J.
