at rest. It is a plant well worthy of cultivation in every collection, beingd 
easy culture, and when in bloom makes a very effective display, with its long 
pendulous spikes hanging from the roof. Nota drop of water should,be given 
until the young growths are about an inch long, and the flower spikes make 
their appearance. The plants should then receive abundance of water, boti | 
at the roots and in the atmosphere. On bright, sunny afternoons, syringing 
the plants overhead will be very beneficial to them. Immediately th 
_ young flower-spikes are seen making their Way up, a piece of wadding 
should be wrapped round them, to protect them from woodlice and slug, 
which are very partial to them. This will effectually keep off these destrue ; 
tive pests. A good way to trap woodlice is to cut a potato in half, hollowing 
the pieces in the centre, then lay them on the compost, and examine both 
night and morning.
