internally, should also be in some way combined. ; Those 
of modern construction are invariably better in this 
respect than many of an earlier date. Only sufficient 
space is here available to give a few general remarks, 
that may be modified to suit individual requirements. 
The selection of position has at times по alternative, 
but if there is an opportunity, an open one with a south 
or south-west aspect should be chosen, so as to obtain all 
possible sunshine in winter. Shelter afforded by trees 
from north and east winds is also a great advantage at 
that season, but they should be sufficiently far away as 
not to overhang the house. Provision for admitting 
abundance of light and air, both at top and bottom, is of 
great i The ventilators at the apex only are 
best for winter use, but all may be utilised in summer, as 
rool-house flowering plants are soon injured in a close 
Atmosphere or а high temperature. А thin shading is 
necessary in bright weather, but is best if placed on 
rollers, to admit of removal at other times. The heating 
apparatus should be capable of maintaining а tempera- 
ture of 50deg. in winter, although it is not always 
advisable to keep so high as this. The pipes are best 
concealed as much as possible under the side stages, 
or a part may be under the floor, covered with per- 
forated iron gratings, through which the heat will pass 
readily. In the formation of the ground plan, sufficient 
width should always be allowed for the paths. These may 
be made of gravel, and covered with white spar or shell, or 
в lasting floor may be formed of ornamental tiles that are 
specially made for the purpose. A kerbing of terra-cotta or 
stone should separate the paths from the beds of soil. 
Sufficient space cannot be obtained for placing many 
plants out of pots in small glass houses that adjoin or 
form part of a mansion.
