CRYSTALWORT Riccia fJiiitaiis grows in masses in small, angular shapes, resembling crystal formation. It floats just beneath the surface and is valuable in the propagation of small tropical fishes, some depositing eggs in it, and the new-born young of the live-bearing varieties using it for hid- ing places. Native to the Eastern States and may be had of dealers in aquatics. DUCKWEED This commonest of all floating plants is found in several species in still pools everywhere. From the middle of summer until cold weather many ponds are completely covered with this green mantle, greatly interfering with the work of collecting daphnia for fishfood. Duckweed itself is a good food for goldfishes large enough to eat it, and has a laxative efl:ect beneficial to the finer breeds. The form most commonly found is Lcmna minor. Propagation is b}- oft'shoot extensions. SALVINIA Of the small floating aquatics Salvinia is one of the best. The heart-shaped leaves with bristle-like growth on the upper surface seem like bits of velvet connected by a thread. The roots are naturally.
