ON VINERIES. 



Society had it in its power to give. The letters a aa 

 show the places where ventilation is arranged, by sashes 

 being framed on the roof on each side of the ridge, and 

 fastened to iron rods running horizontally, each of the 

 rods reaching half the length of the house and meeting 

 in the middle ; there are also loose joints, fixed on the

 framed and built in the brickwork ; these are opened 

 by means of iron rods and levers. The outside borders, 

 c, may be covered with glazed sashes or wooden shutters 

 whilst the vines are being forced, which will keep out 

 frost, snow, and rain, the effects of which I allude to 

 in another part of this treatise. The house is heated 

 with six rows of 4-inch hot-water pipes, as well as by a 

 broad and well-constructed flue, running underneath a 

 trellis path in the centre of the house, marked d. The 

 flue was placed in this vinery from necessity, not from 

 choice. I would have much preferred hot-water pipes, 

 as I found when I had to fire sharp in hard weather, 

 the flue got too hot, and destroyed the healthy state 

 of the atmosphere. I, however, found that, owing to 

 the position of the flue, a considerable amount of heat 

 diffused itself through a portion of the borders on each 

 side of it, which, with the assistance of the surface 

 pipes, was very beneficial. The roof and wall plates were 



principally composed of the best crown Dantzic timber,
