160 PLANTING AND MANAGING 



3d. Pave the whole area of the bottom with good 

 hard bricks, well jointed together, either with cement 

 or well prepared mortar. 



4th. Then lay the foundations of the walls of the 

 vinery on this flooring of brickwork, and carry the 

 walls up liollovj as high as the surface of the adjacent 

 soil, so that the materials about to be enclosed in 

 them shall be protected from the chilling effects of the 

 soil outside, and from any sudden accession of water 

 that may at any time fall thereon. The walls may 

 then be continued solid up to their intended height, 

 although every house intended for the early forcing 

 of grapes ought to have all its exterior walls built 

 hollow from top to bottom. 



5th. As the floor of the vinery is to be laid with 

 bricks, the surface of which is to be an inch higher 

 than that of the surrounding soil, provision must be 

 made for the bearing of the sides and ends of such of 

 the paving-bricks as will come in contact with the 

 walls, by having a set-off" in the brickwork of the 

 sides and ends of the walls of not less than an inch 

 in breadth. 



6th. Now, as a series of walls are to be run up 

 parallel to the ends of the house, for the flooring- 

 bricks to rest upon, the next step to be taken is to 

 divide the area oi the bottom into as many equal por- 

 tions or breadths as shall be equal to the number of 

 vines intended to be planted. 



Thus, if the vines are to be planted four feet apart, 

 draw a line from the front to the back, that distance 

 in the clear from one of the end walls, and on this 

 line run up a wall to such a height that the surface of 

 the top of it shall range exactly even with that of the 

 set-off" in the main walls. This cross-wall must be 

 built solid, and in the usual manner, with the bricks 

 laid flat; the breadth of it will, therefore, be about 4J 

 inches, giving a bearing to the flooring-bricks of 2\ 

 inches. Then divide the space thus enclosed, into 

 parallel spaces of the same width as the bricks are 

 long. On all the sides that mark the divisions of
