Section 8. 
FERNS IN DWELLING-HOUSES. 
WHE condition of atmosphere and the lack of 
light in dwelling-houses are such that few 
Ferns can grow satisfactorily. They have a 
better chance where oil is burned than when 
gas is used for lighting, because gas dries and vitiates 
the atmosphere to a much greater extent. They have 
also a better chance in large than in small rooms, as the 
fluctuations of temperature are neither so sudden nor so 
extreme. 
They are often killed by not having sufficient light. 
They are frequently placed a long distance from the 
window, where they soon become weak and sickly-look- 
ing, and their owners wonder whatever isthe cause. Itis 
impossible for plants to be healthy and strong without 
plenty of light; therefore they should be as near the 
window as possible, and be shaded only from the hot rays 
of the sun. 
A north window is the best, as the light is usually 
allowed unrestricted entrance, neither is there any risk 
of scorching at a window of this aspect. They do well 
facing east, west, or south, though at the latter they 
must be shaded when necessary. Apart from this, they 
must have all the light with which it is possible to pro- 
vide them. : 
They should be kept out of draughts, as cold currents 
of airdo them harm. A hot, dry atmosphere, caused by 
large fires and burning of gas, is also injurious.
