in the rafters to keep the wet from the joints, and prevent the 

 lights from being blown away. The windov/s [e) are kept open 

 by a fastening in the shape of a quadrant, which, being screwed 

 on the side of the window, passes through a narrow plate 

 fastened in the uprights, and furnished with a screw to fix the 

 window at any desired height. 



Vinery {fg. 85. a and fg. 86. d). — The pendent trellis 

 {Jig. S6./) is fixed to each of the rafters, the perpendiculars of 

 which are made of narrow hoop-iron, and the horizontals of 

 copper wire, except the lowermost six, which, to keep the per- 

 pendiculars at their proper distance, are made of thin iron 

 rods. The vines are trained on the back wall, as well as on 

 the trellises ; and the upper branches are pruned by resting a 

 plank on a ladder at each end of the house. Planks (g) are laid 

 on bricks to walk upon, instead of pressing down the border. 

 On this border (k) the green-house plants are set in winter. 



Succession Pits {Jigs. SI. and 88.). — The succession pit 

 {Jg. 87.) is built at one end of the pinery. {Jigs. 85. and 87. m) 

 Its flue {k) opens into the pinery flue at this end only ; so that,

though the air of the pinery flue enters it, it has no current 

 through. Fig. 88. is a section of the pit. It has a steam flue {I) 

 which is closed at both ends, but the external wall of it is open 

 brickwork; so that the steam from the dung passes into the 

 flue, and thereby warms the air of the pit. For the same pur- 

 pose, a thick tarpawling made to roll up and down on a pole, 

 ^o as to cover the glasses in cold weather, may be used. The 

 space outside the pit is filled with tan up to the level of the bed 

 inside once a year, generally in November ; and above that is 

 put dung, which is renewed as often as the heat declines. In-
