PLANTS IN ROOMS.

made about the same temperature as the room in which 
the plants grow; never use it fresh from the pump, 
either let it stand in a room all night, or take off the 
chill by a little warm water, otherwise the growth of 
the plants will be much checked. 
3. Extraneous matter collected on the leaves may 
either arise from insects or dust ; the former may be 
speedily remedied, by placing the plants under a hand¬ 
glass, or anything that is convenient, and burning some 
tobacco until they become well enveloped in the smoke ; 
and the latter may be removed by occasionally wash¬ 
ing them on the head with pure water, either by means 
of a syringe, the nose of a watering pan, or with a 
sponge, when the dust still adheres. 
Bulbs of most sorts flourish in rooms with less care 
than most other plants. Hyacinths should be planted 
in autumn. Fill the pots with light rich soil, and plant 
the bulbs so shallow that nearly half the bulb stands 
above the soil, place the pots in the open air, and 
cover them six or eight inches with rotten bark. Dur- 
ing spring, take them out as they are wanted to bring 
into flower, and set them in the window of a warm 
room, where they will be exposed to the sun. When 
the leaves begin to decay after flowering, give them no 
water, when the leaves are dead, take them out of the 
soil, and lay them in an airy situation for planting. 
“ If grown in water-glasses, they require to be placed 
in a light airy situation, and the water must be changed 
every three or four days.
