PARK AND CE/AETERY. 
Details are omitted in the plan. The roof should 
be shingled and sides sheathed with matched stuff; 
outside of this should be a thickness of building pa- 
per and the outside finished with siding, or drop 
siding, in the usual manner. Building paper treat- 
ed with tar should not be used as the tar weakens 
the fiber of the paper, and in a few years it crum- 
bles and thereafter gives but little or no protection. 
The shed should be well lighted with 3 or 4 
windows. The doors leading into the greenhouses 
from the shed are 7-8 inch batten doors. A sub- 
stantial bench will be needed for potting. This 
should be about three feet wide, two and a half feet 
high and about six feet long. If space is needed 
for two men to pot, two benches should be built, as 
they can not conveniently work at the same bench. 
Suitable racks and shelves should be provided for 
the storage of pots, tools, etc., and bins for soil. 
The soil bins can be under the potting benches and 
under the greenhouse benches. If the soil is dry 
or can be drained, it will be best to excavate a cel- 
lar under the shed for the boiler, coal and ashes, 
giving more room above and shutting in the dust. 
If this cannot be done, a pit must be dug as deep 
as possible and bricked up, the wooden floor being 
carried only to the edge of the pit. The pit or cel- 
lar must be large enough to contain the boiler and 
allow space for coal and ashes. The boiler must 
be well away from the walls so that it can be inspect- 
ed from all sides, and a flue cleaner can be used. 
The room needed will vary with the size and style 
of boiler. It should be born in mind that no un- 
protected wood work should be nearer than three 
feet from the smoke pipe of the boiler. 
The smokestack can be of plain or galvanized 
iron if necessary and run through the roof if well 
protected. The danger from fire however, is great, 
and the gases from the coal, especially if it contains 
much sulphur, rapidly corrodes the iron. A brick 
stack is much to be preferred and will be cheaper 
in the end. A foundation should be built for the 
stack of solid stone or hard burned brick masonry, 
using cement mortar, and extending down to solid 
ground below frost and at least six inches below 
the cellar or pit bottom. It should be probably a 
little larger than the base of the stack. The stack 
should be built of good brick laid in cement mor- 
tar and tapered or battered from the base up. The 
base should be, for perfect safety, a square, of 
which each side is not less than one-tenth the height 
of the stack. In practice the base is frequently 
made smaller and such chimneys do not always 
blow down but it is best to be on the safe side. The 
opening at the top of the stack should be of such 
size as is required by the boiler. The walls of a 
stack of moderate height may be four inches. 
Greenhouse smokestacks are built from twenty to 
fifty feet above the boiler. If there are buildings 
or trees near, which shut off the wind, the stack- 
must be carried higher than would otherwise be 
necessary. It should be born in mind that the 
higher the stack the better the draught. 
The south and north sides of the shed should 
not be sided until the greenhouse and propagating 
house roofs are it place. The sides of the houses 
consist of six inch posts, set three feet in the ground 
spaced as shown in Fig. 5 and projecting four and a 
half to five feet above ground. To these are nailed 
one thickness of ship-lap. Common flooring is not 
good for this purpose as the joints are square across 
the wall and will hold moisture, causing decay. 
The ship-lap having diagonal joints, if properly 
laid with the upper board overlapping the under on 
th& inside of the house \v\\\ keep any water, when 
using the hose, from getting inside the double walD. 
On the outer walls two thicknesses of building pa- 
per are tacked, and outside of this drop siding is 
used. The drop siding is laid with two upper boards 
lapping the lower on the outside of the house and 
this turns all water from that direction. The 
top piece of ship lap is let into a groove in the 
under side of the gutter bottom, making a tight 
joint there. 
The top of the posts are sawed off, after being 
set in a line, to carry the gutter or wall plate as 
may have been decided on. The gutters and wall 
plates, and in fact the complete houses are not set 
level north and south, but have a fall of three or 
four inches to the south in a fifty-two foot house in 
order to carry the water away quickly. 
At the peak of each roof is placed a ridge piece 
extending the length of the house and supported 
by one inch iron pipe. The pipes are set about 
eight feet apart and stand on pieces of stone which 
are first rammed into the ground far enough to be 
firm. If the pipe are cut into two pieces and join- 
ed by couplings, after they are in place, they can 
be unscrewed slightly in order to give them a firm 
bearing above and below. Wooden supports, two 
by four inches, are often used but the lower ends 
soon decay, allowing the roof to sag. 
From the gutter, or plate, to the ridge, sash bars 
are placed corresponding to the rafters of an ordi- 
nary house. The height of the ridge should be such 
as to give a rise to the sash bars of six or more inches 
to the foot. The gutter should be of such heightthat 
with the rise or pitch of the bars there will be suffi- 
cient head room over the walk. A height of four 
feet six inches to the sash bars at the wall and 9 feet 
6 inches or more at the ridge wdll answer very well 
for the twenty foot house. The sash bars are spac- 
ed to correspond with the size of the glass to be us-
