the front and roof may be made each in 

 one piece or in separate parts. The most 

 feasible way would be to make the wood- 

 work below shown as panels in the draw- 

 ing and the glazing above, in four separate 

 pieces, as the two pieces in the centre 

 could then be made to open for ventilation. 

 The roof may be made in three pieces, 

 and in this case the two central panels 

 should terminate at a cross-rail set across 

 the frame at A and B, to admit of small

lights above between this rail and the top 

 rail of the roof for ventilation. The house 

 stands on a platform on sill-piece of oak 

 framed separately, and the sills, on lower 

 rails of the framing above, are screwed 

 down upon it. It is almost needless to 

 say that the oaken sill should be bedded 

 on concrete, and that the floor of the 

 house should be formed of the same 

 material, sloped from all sides to one 

 corner, at which an outlet and drainage 



should be provided for surplus water that 

 may fall on the floor when the plants are 

 watered. For the sake of ornament cir- 

 cular heads may be made to the lights, if 

 preferred to square or rectangular heads. 

 In Figs. 4, 5, and 6 the details employed 

 in bolting the front (and back, if the house 

 be furnished with a wooden back) to the 

 roof of the uprights at front and back are 

 clearly shown. In Fig. 4 the plate A is 

 mortised into the post B, and a hole is 

 bored with an auger through post 

 and tenon until a recess notched 

 in the plate below A is reached, in 

 which the nut is held until the end 

 of the bolt has been passed through 

 it. The nut, which is circular, with 

 notches on its edge like the milling 

 of a coin, is then screwed up tight 

 with a screw wrench made in the 

 form of a large pair of bent pliers, 

 until the post is brought as closely 

 as possible against the tenoned end 

 of the plate. The framing of the 

 roof is secured in precisely the 

 same manner as shown by the 

 bolts in Figs. 5 and 6. In these 

 the shaded parts of the top, lettered 

 A, represent in Fig. 5 the front 

 rail, and in Fig. 6 the back rail 

 of the roof; and in each of these 

 figures the shaded part of B repre- 

 sents the top rail of back and front 

 respectively ; for even if the back 

 be formed by a brick wall, or 

 the wall of a house, or any other struc- 

 ture, a wall plate from end to end will 

 be required to help in supporting the 

 framing that forms the roof. A fillet is 

 nailed on the sides of the roof to give 

 a. finish to this part of the structure, 

 and to prevent the rain from finding its 

 way to the bolts, caps, as shown in the 

 front and end elevations and in detail in 

 Fig. 6, are placed at the four corners of the 

 roof. The difference in the form of the
