12 THE FORCING GARDEN. 
the days draw out. Give top ventilation during hot 
sunny weather ; shade and close at four o’clock. 
Shading.—I have found that a green shade ofa light 
nature is a good thing and that a very thin transparent 
green paint laid on the glass outside for the summer is 
good for some things. But for Cucumbers I can hardly 
recommend it ; fine green gauze is as good as anything 
for shading the sunny side of the roof, but none will 
be required for the north side. If the gauze is sewn 
together, with tapes sewn all round the edge, and one 
across the whole width (%.e. the width of the south 
roof), at distances of three feet, itcan then be tacked 
on the roof and strained quite tight. The shading 
may remain on during the hot months without any 
harm. 
When the young Cucumber plants begin to bear 
the old ones should be removed, for they will only en- 
gender numerous insect pests. Clear all out, therefore, 
soil and all, except a few inches to form a surface on 
which to place pots of Balsams, Cockscombs, young 
Primulas, &c. Iam not disposed to raise the expecta- 
tions of anyone too high, but I may assert for a fact 
that by good practical judgment and management such 
a house can be made to pay more than the cost of 
erection the first year, but not if you go to professional 
builders, for then such a house complete will cost fully 
501, more, heating apparatus and all. For the satis- 
faction of some I may venture on an estimate of what 
may be made from such a house the whole year in and 
out :—Asparagus, say 20/.; early Cucumbers, say 800 
at 1s. each, 40/.; late ditto, 800 at 6d. each, 201.; cut 
Lily-of-the-valley from the pit across the end, say 
2,000 spikes, more or less, at 81. per 1,000, 16/.; 300
