THE WHOLE YEAR. 
r BY MR. WILLIAM MATTHEWS. 
Gardener to Lady Palmer , of Wanlip Hall, Leicestershire. 
The purport of the accompanying design is the formation of a dou¬ 
ble Vinery (fig. 9) which is divided into four parts (a b n d) each 
division to be 20 feet long, 12 feet wide, and to contain six vines, 
which are to be planted on the front borders, and brought into the 
house through holes in the wall, and laid into a border (e) between 
two and three feet wide, of good compost earth, betwixt the front 
wall and flue (f) they are then to he he arched over the flue and 
front walk (y) and layed into a border ( h ) five feet wide of the same 
sort of compost as before, and raised up to the centre, by this method 
a double crop can he obtained, each vine containing 24 or 25 feet of 
rodding, (the usual number is generally upon the old plan 12 or 13 
feet) and in each compartment 144. It is to have a span roof divi¬ 
ded by glass partitions, the one in the centre to slide, so that one or 
two may he worked together, the glass partition in the centre to he 
glazed only half the length of the house, so that when the fruit is cut, it 
may be slided along between the other two divisions. The centre 
partition may he divided into four feet sashes, for the greater conve¬ 
nience of sliding. A copper or tin pipe (k) made of light materi¬ 
als is fixed to the top near the centre of the roof, having small holes 
in it, also a ventilator at each end and centre of the house, the pipe 
may he from four to six inches in diameter, for the convenience of 
carrying off the condensed air. The sashes (/) in front are from 3 
to 4 feet deep, hung by joints at the top, with a small iron bar at the 
bottom (in) having small holes for giving air at pleasure. The water 
cisterns to he fixed over the fire furnace (p) and a tap to draw, fixed 
in the wall. A small arch may be turned over the top of the para¬ 
pet wall along the front, three feet in height, for holding up the soil' 
for the centre border. Dampers to he used in the flues, one in the 
centre flue, and the other in the cross one, so that one or both mav 
he worked at pleasure. The vinery to have six doors (n) two at 
each end, and two in the centre. The roof to be supported by iron 
columns, one under each rafter. The front walk (g) to be sunk for 
the convenience of head way, and to rise to the centre walk ( o ) with 
steps. The plan of this house may he adapted for forcing Peaches, 
with the exception of the front walk and flues. The front walk and 
flues should be upon arches for the convenience of admitting the 
roots into the front border. Two vines may he planted in each di-
