grows below the angle of the rafter. The 

 flues may be constructed as directed 

 above for the early vinery of the same 

 authority. " The number of furnaces 

 must be regulated by its length. If under 

 35 feet, one furnace will do. The para- 

 pet and front flue of both houses should 

 stand on pillars 3^ feet deep under the 

 ground-level, in order that the roots of 

 the plants may have free scope to run to 

 the border without the house, as the in- 

 tention is to plant them inside, and train 

 them under the roof to a trellis fixed to 

 the rafters." 



Continental vineries are, as with our- 

 selves, of great variety and form. Port- 

 able houses are erected against walls 

 already covered with vines, and sometimes 

 depending entirely on solar heat ; while 

 at others, fermenting materials are em- 

 ployed, as in fig. 405 — the part at a being

 kept refreshed in temperature by the 

 addition of fresh, and the subtraction of 

 decayed, dung. " The most perfect form 

 of vinery on the Continent in general use 

 may be understood by a reference to fig. 

 406. It is a house of variable dimensions,

case which came under our observation, is 

 faulty in not being elevated clear of the 

 ground. These flues usually make one or 

 more turns (b) close to the back wall. 

 Vines are planted within, and trained to 

 the back wall against a trellis, and also 

 in the front, sometimes within, and at 

 other times without, the house ; and 

 these are trained up the roof." — Pract.

 linings of dung are placed against the 

 back wall, and hot-water pipes are laid 

 parallel to the front wall, over which is
