rectly under the walk; the walk itself being formed by an opes 
grating or lattice, through which the heat rises freely. The 
arrangement of the flue will be better understood by referring 
to the ground plan (II.) In this the furnace is indicated at d, 
in the back wall;* from this the flue rises gradually to e, 
whence it continues nearly the length of the house, and return- 
ing enters the chimney at f. For the convenience of shelter, 
firing, etc., it is usual to have a back’ shed, g, behind'the back 
wall. In this shed may be a bin for wood or coals, and a sunk 
area (shown in the dotted lines around d, f,) with steps to. de- 
-scend to the furnace and ash-pit.| There are two doors, h, in 
the vinery at either end of the walk. 
The border should be thoroughly prepared previously to 
planting the vines, by excavating it two feet deep and filling it 
up- with suitable compost. This is best formed of one half 
loamy turf, well rotted by having been previously laid up in 
heaps, (or fresh and pure loamy-soil, from an old pasture or 
common;) one third thoroughly fermented horse or cow ma- 
nure, which has laid in a turf-covered heap for three months; 
and one-third broken pieces of charcoal and old lime rubbish. 
The whole to be thoroughly mixed together before planting the 
vines. 
The vines themselves should always be planted in a border 
prepared inside of the house, and in order to give the vines that 
extent of soil which is necessary for them, the best cultivators 
voake an additional border twelve or fourteen feet wide outside, 
in front of the vinery. By building the foundation of. the front 
wall on piers within a couple of inches of the surface, and sup- 
porting the wall above the surface on slabs of stone reaching 
from pier to pier, the roots of the vines easily penetrate to the 
*border on the outside, — 
The vines should be planted early in the spring. Two year 
old plants are preferable, and they.may be set eighteen inches 
from the front wall—one below each rafter, or, if the latter are 
over three feet apart, one also in the intermediate space. 
The pruning and training of the vines we have already de- 
scribed. The renewal system of pruning we consider the best 
* This furnace should be placed two feet below the level of the flue at 
é, in order to secure a draught, after which it may be carried quite level 
till it enters the chiraney. An air chamber may be formed round it, with 
a register to admit heated air to the Mouse when necessary. A furnace 
fourteen inches square and deep, with an ash-pit below, in which anthrar, - 
cite coal is burned, will be found a very easy and perfect mode of heating 
a house of this width, and ‘thirty feet long. 5 
+ The most perfect: vinery that we have seen in this country is one of 
two hundred ‘et long at the country residence of Horace Gray, Esq., 
Newtown, near Boston. It is built of wood, with a curved span roof, 
after a plan of Mr. Gray’s which seems to us to combine fitness and beauty 
in an unusual degree. ~
