HOTHOUSES. 87 



pipe, with light and shutter in roof ; the fuel store, S ; the boiler 

 house, T, necessarily 9 ft. below the ground-line ; the potting shed, U, 

 with entrance also from the plant house, J, and fitted with bench, pot 

 rack, bars, etc. ; a fitted office and seed room, V, from which is 

 entered the fruit room, W, with stages and grape bottle rests on 

 each side of a central path, having a 4 in. flow and return. There 

 are "hit and miss" ventilators next the ground-line, and a large 

 ventilating shaft in the roof. The walls are built hollow, that is, there 

 is a 2*4 in. span between the brickwork, and there is a large light 

 and shutter in roof. Then follow sleeping and mess rooms, X and Y. 



In the second example we have a main range of lean-to hot- 

 houses 150 ft. long, with five span-roof pits in front, each 40 ft. 

 long, and an orchard house behind, 150 ft. long. The main range 

 embraces an early vinery, A, a muscat vinery, B, an early peach 

 house, C, a late peach house, D, and a late vinery, E, with, at back, 

 a boiler house, F, a fuel store, G, a potting shed, H, an office and 

 seed room, J, a fruit room, K, a mushroom house, L, and an open 

 shed, M ; O and P are two stove pits ; Q and R are pine stoves ; 

 S and T are two propagating greenhouses. The orchard house at 

 the back of the main range consists of a three-quarter span house, 

 5 ft. 6 in. wide, with the side lights almost vertical. This house is 

 so framed that the lights can be taken off in summer. There is a 

 separate boiler to these orchard houses, owing to the necessities of 

 the climate. A peculiar feature to be noticed is that the roof and 

 vertical lights of the main range and pits have double glazing, as 

 a protection against frost and snow. The roof lights consist of 

 two framed sashes resting on the main rafters, whilst the double 

 arrangement of glazing in the front lights is provided by the 

 additional glazing being fixed on these lights by screws. The 

 outer glazing is removed in summer.
