put through the top and bottom into the ridge-tree and rafter- 

 plate. The rafters and studs must likewise be secured by tliese 

 screws, as at Figs. 11 — 4. In the section, Figs. 1, 2, and 8, 

 show the door stud, the angle stud, and one of the side studs, 

 which are all of one size, the difference consisting only in the 

 putting on of splines and mouldings. The end gable lights 

 may be fixed in their places by means of splines, in the same 

 manner as the side sashes. In the same section, Fig. S repre- 

 sents light iron rods suspended from the rafters, as bearers of 

 light shelves, for the accommodation of bedding plants, or 

 other small things which require a situation near the gLiss. 

 Eeferring to the ground plan (9, 9, 9, 9) are boxes placed iu 

 the angles, in which may be planted climbers, to train over 

 the roof or sides of the building. Fig. 7, stage, which must be 

 strong enough to bear the plants, but may be made in parts, 

 BO that it can be removed without having to be knocked to 

 pieces. It will be necessary, in order to protect the building 

 from damp and the liability to settle down, to place it upon 

 some firm and solid matter let into the ground, as brick piers 

 or wood blocks. A platform of bricks laid on the surface, 

 gives a firm and lasting foundation, provided the subsoil has not 

 been recently disturbed. 



The heating of a moveable house must also be managed by a 

 moveable apparatus, which will be some kind of stove, and 

 which must have a pan on the top to hold water ; and as arti- 

 ficial heat in such a house as this will only be required in 

 winter, the stove might, for that period, occupy a place near 

 one of the doors, and the smoke-tube be carried through the 

 glass at the top of the house. Should a building of this kind 

 be required for vines, the side lights should be reduced to one 

 half the height, and these to open, as here shown, for ventila- 

 tion ; the roof lights would then be longer, and a much steeper 

 roof obtained. A small aperture or two at the ridge, capable 

 of being closed by a wood slide, would, with the side liglits 

 hung as recommended, effect a perfect ventilation. The walk 

 would, in such a house, be down the centre, and the vines 

 might be planted in boxes, having large openings in their bot- 

 toms to allow the roots to escape into a border made up inside 

 the house for that purpose. The planting them iu boxes 

 would enable them to bear removal at almost any season.
