the ground plan, Fig 2, to face full south. In such case it

a due north aspect, which is somewhat a disadvantage, as 
the sun would have little effect upon it. In order to 
emedy this, one-third in depth of the upper part of the 
central longitudinal division wall might be of glass, which 
ould allow a considerable portion of light to pass through 
from the southern side, and thereby obviate theevil. Sueh

house for flowering plants, and answers admirably. There 
is, however, no objection, where circumstances will permit 
of choice in location, to the placing of the front aspect a 
few degrees east of south, which would in an equal ratio 
turn the northern side towards the west, indeed all things 
considered it would be as well for all requirements. If a
