be sufficient to keep it moist enough for six or eight 

 weeks. In winter the temperature of the room in which 

 the Wardian Case or Fernery is kept may run from fifty

 kind are particularly well adapted for growing Hyacinths 

 in winter, if desired ; but they must first be placed in 

 some cool, dark place, so that the roots may be formed 

 before being brought into the light. (See special in- 

 structions on this head under "Fall or Holland Bulbs.'') 

 When the Cases are brought into the room they will re- 

 quire daily ventilation. The Lily of the Valley can also 

 be grown finely in a Wardian Case. (See '"Fall or Hol- 

 land Bulbs.")

THE taste engendered by growing plants in rooms 

 often results in a desire to have more appropriate quarters 

 for the plants, and a greenhouse follows. This always 

 affords the most satisfaction when it is so attached to the 

 dwelling, that opening a door or window from the dining- 

 room or parlor reveals the glories of the greenhouse. 

 The greenhouse, when attached to the dwelling, should 

 be always on the east, southeast, south, or southwest 

 sides, never on the north, if flowering plants are to be 

 grown ; though Ferns, Lycopods, Palms, and other 

 plants grown for the beauty of their form or foliage, will 

 do quite well in the shade of a northern aspect. It may 

 be of any length or width desired. If of ten feet width, 

 it will cost for erection from forty to sixty cents per 

 square foot of the glass surface, according to the char- 

 acter of the work. If twenty feet wide, from forty to
