42 HORTICULTURE. 



two, or sometimes three hours after sunset ; and if our air-tight 

 one of good size, and constructed as it should be, so as to maintai 

 a good fire for a long time, our last replenishing in the evening nee 

 not usually be later than ten o'clock ; but we must, in this case, gi^ 

 a full supply of fuel for the night's consumption. 



Every sensible person will, of course, use light outside shutter 

 for the roof and side glass of such a house as this. We slide thei 

 on at sunset, and take them off at sunrise; and by this means w 

 not only save one-third of our fuel, but keep up a pleasant greei 

 house temperature, without cold draughts at night. It is wort 

 while to remember, too,, that in glazing the roof, the most usefi 

 possible size for the glass is 4 by 6 inches, or, at the largest, 6 by 

 inches. The former answers the purpose perfectly, and is not onl 

 much less costly than large glass, but is also far less expensive t 

 keep in repair ; neither hail nor frost breaking the small panei 

 as they do the large ones. 



As to the minor details, we will have a small cistern under tl 

 floor, into which the water from the roof can be conveyed for wate: 

 ' ing the plants. Beneath the centre stage (which may be parti 

 concealed with lattice work), we may keep our dahlia roots, and 

 dozen other sorts of half hardy plants for the summer border, no 

 dormant, and snugly packed quite out of sight. 



We did intend, when we sat down, to give our novices a great dei 

 of exceedingly valuable advice about the sorts of plants that they ougl 

 to cultivate in this glazed flower-garden. But we see that we ai 

 getting beyond the limits of a leader, and must not, therefore, weai 

 those of our subscribers, who take no more interest in geraniun 

 than we do in Irish landlords, with too long a parley on exotics. 



We must have space enough, however, for a word or two mo] 

 to beginners. Let them take our word for it — if they prefer a 

 abundance of beautifiil flowers to a pot-pourri, of every imaginab 

 species that can be grown under glass, they had better confine then 

 selves to a few really worthy and respectable genera. If they on] 

 want winter-blooming plants, then let them take Camellias and Oh 

 nese Azaleas, as the groundwork of their collection, filling in tl 

 interstices with dauhnes, heaths, sweet-scented violets, and choi(
