4 FRUIT CULTURE UNDER GLASS. 



for summer growth ; but, for six months of the year, 

 they do not, from their position, embrace so much 

 direct sunshine as a lean-to house facing due south. 

 Moreover, from the greater amount of glass as a radi- 

 ating surface in span-roofed houses, they require more 

 fire-heat to keep up the temperature. In these respects 

 the lean-to gives advantages over the span-roofed pinery, 

 in whatever position the latter is placed. Tor starting- 

 pines in December and the two following months, as 

 well as for swelling off fruit during winter and early 

 spring, I recommend lean-to houses, as represented by 

 fig. 2. 



FIG. 2. 



The dimensions of the two pineries represented by 

 the woodcuts, are 40 feet by 18 feet, which give a house 

 of handsome proportions. But as the extent of the 

 pineries must be guided entirely by the supply required, 

 I will not enter further into this question. Suffice it to 

 say, that it is more desirable to have several structures 

 of moderate size than a less number of larger ones. A 

 constant succession of ripe fruit is much more easily 

 kept up by having a number of compartments.
