HOUSE AND GARDEN

consider, as the accompanying 
diagram shows—namely, south 
wall, gable ends, roof and open¬ 
ings. For the roof we will re¬ 
quire a ridge against the wall of 
the dwelling house, sash - bars 
running at right angles to same, 
and a “purlin,” or support, mid¬ 
way of these, and a sill for the 
lower ends. For the south wall 
we will need posts, one row of 
glass and boards and “sheath¬ 
ing.” For the gable ends, a 
board and sheathing wall to the same height, and for the balance, 
sash-bars and glass. The required openings will be a door or 
doors, and three ventilators, to give a sufficient supply of fresh air. 
For these the material required will be:

All of the above will have to come from a greenhouse ma¬

charges. The following items may probably be bought more 
economically in your immediate vicinity, and the prices will vary 
in different sections of the country:—

Level off a place about 22 x 12 
feet, and set in the posts as indi¬ 
cated in the plan on page 92, 
taking care to get the lines for 
the ends of the house perfectly 
square with the wall, and exact 
in length. This is best done bv 
laying out your lines first with 
stout string, and making your 
measurements accurately on 
these. Then put in the posts 
for sides and 
ends, setting 
these about three 
feet into the 
ground, or, bet¬ 
ter still, in con¬ 
crete. Put in 
the two corner 
posts which 
should be square 
first. Next saw 
off all posts level 
at the proper 
height, and put 
in place the 2 x 
4 in. eaves plate 
on top of these, 
and the 2 x 6 in. 
sill just far 
enough below to 
take a 16 x 24 
in. light of glass, 
with its upper 
edge snug in the 
groove in lower 
side of plate, as 
shown in detail 
of section on page 92. Fit the 2x6 in. sill about the posts so 
that the mortise on same will just clear the outside of posts. 
Then put on the siding on sides and ends — a layer of rough 
inch-boards, a layer, single or double, of tar paper, and a second 
layer of boards, covering on the outside with shingles, clap¬ 
boards or roofing paper. The five 7 ft. x 1% in. pipe posts may 
now be placed loose in their holes, and a walk dug out of suffi¬ 
cient depth to allow passage through the middle of the house. 
Rough boards, nailed to stakes driven into the ground, w’ll hold 
the earth sides of this in place. 
Next, after having it sawed in two perpendicularly (thus 
making 20 ft.), screw the ridge securely to side of house at 
proper height, giving a thick coat of white lead at top to insure 
a tight joint with house. Now put one of the end bars in place, 
taking care to get it exactly at right angles with ridge, and then 
lay down the sash-bars, enough more than 16 in. apart to allow 
the glass to slip into place readily. Take a light of glass and try 
it between every fourth and fifth bar put into position, at both 
ridge and eave, as this is much easier than trying to remedy an
