Greenhouse Construction 
I wish to make a greenhouse, even 
span, 11x21, using seven hotbed sash 
(3x6) on each side of ridgepole, running 
north and south. I have a quantity of 
114-inch pipe, hotbed sasli and cord wood. 
Side walls and south end walls 4 y 2 feet 
high, doubled and papered; glass in south 
Ka ble only (none below plate in south 
wall), north end protected by furnace 
room wall 10 feet high. I wish to use 
made-up coil (1*4-inch) in furnace to 
use four-foot wood, if practical. How 
many feet of 1*4-inch pipe will be re¬ 
quired to heat this house for coils in fur¬ 
nace to forcing temperature and how 
many feet 114-inch for heating coils (hot 
water), under benches? Would it be bet¬ 
ter to run flow pine under ridge with re- 
to return at heater, and each flow at 
highest point must have a small pipe 
leading to top of expansion tank as shown 
as air vent in diagram. Each coil in 
heater should have two flows to south end 
and four returns. The grate should be 
arranged with several heavy iron plates 
to shut off draft, as best results are ob¬ 
tained when burning wood by having a 
very small opening for air to get through. 
The fireplace should be length of cord 
wood, and quite narrow, unless it is de¬ 
sired to place a large quantity of wood 
on fire at one time, 10 to 12 inches wide 
turns under bench, or a complete circuit 
entirely under benches? In recommend¬ 
ed system how much lower should furn¬ 
ace be than the returns or heat coils in 
greenhouse, and how much fall to pipes? 
Give size and height of stack and proper 
dimensions of grate, and state where 
highest point in system should be, also 
locate expansion tank. Our temperatures 
here run lower than in your section. The 
past Winter we had 40 dog. below for 36 
hours, and from 10 to 20 deg. below for 
days at a time. n. m. S.

A greenhouse 11x21 feet and 4*4 feet 
side exposure, where temperature ranges 
as low as 40 deg. below zero, would re¬ 
quire at least 12 lines lA/i-hich pipe to 
furnish enough heat. It would be best 
for the circulation to carry several flows 
overhead to south end and return under 
benches, dividing the returns on either 
side, and allowing two returns to each 
flow, for so short a run. In building 
heater of 1%-inch pipe about 30 feet 
would be necessary to heat 2.">0 feet in 
house, as roughly speaking about one foot 
in furnace is required for eight to 10 
feet in house. The furnace can be con¬ 
structed of brick in the form of an arch, 
allowing three feet or more from grate to 
top, and making same about 4*4 to five 
feet long, and arranging pipe in coils on 
either side near top of arch, as in sketch. 
On each side of fireplace put an iron 
plate possibly 18 inches high and line 
inside with fire brick, allowing several 
inches between iron at top and outside 
brick arch, for passage of smoke down¬ 
wards. Take smoke out of heater at side 
on a level with grate. Return bends, four 
in number, would be necessary to connect 
pipe in heating coil. High point of sys¬ 
tem should be above heater, and from 
there all pipe should continually descend 
about one inch to five feet or more if 
convenient, to return into heater. 
Re careful to have the pipe in heater 
continually ascending from inlet to out¬ 
let. Expansion tank should be connected 
being more than necessary to generate 
enough heat. 
The smoke outlets as shown should be 
at the sides near the rear; a 10 or 12- 
inch terra cotta pipe a few feet above 
roof of house would he ample chimney. 
The coils of beater should be several feet 
below returns under benches. Addition¬ 
al heat can be obtained by running smoke 
flue length of house under bench, as a 
heater of this size burning wood would 
throw out quite a lot of heat into chim¬ 
ney. A much simpler, cheaper and more 
economical heating system would be one 
or two stoves constructed for burning 
wood, having one large one near center, 
or one smaller stove near each end, pro¬ 
tected by sheet iron shield to cause heat 
circulation, shield to run from within 
eight inches of ground to a foot or more 
above top of stove, and allow eight or 
10-inch air space round stove.

Removing Soot from Flue. 
Is there any chemical that oue can 
burn in a furnace and brick flue of a 
greenhouse, to destroy the soot, and thus 
avoid wiping them out at intervals? The 
flue is return brick 0x13 inches and 100 
feet long, and is covered with fireproof 
brick slabs. j. 
I have never heard of anything to do 
an effective job of flue-cleaning, except 
brushing. Burning zinc has been spoken 
of by different persons, but I have never 
found anyone who actually tried it, and 
am sure it would be ineffective in so 
large a job as J. has to contend with. 
We use a hose and good stream of water 
for a similar job, and J. can start at 
high end of flue and wash it out in that 
manner, by making several openings at 
intervals of sufficient distance apart to 
make a good job. To clean a small ver¬ 
tical flue we have taken a bag filled with 
sand or some lighter material and worked 
it up and down chimney with a rope and 
removed soot at bottom. e. j. w. 
Your Neighbor Carries 
An Ingersoll 
Today 40,000,000 persons carry Ingersoll 
Dollar Watches . A price of One Dollar 
had something to do with this enor¬ 
mous sale. But no watch, no article, 
no piece of goods could ever attain 
such mammoth proportions on price 
alone. Sheer merit tells. Your neigh¬ 
bor carries an Ingersoll and he told 
the man next door it was a good watch. 
That is the basis—the backbone of this 
tremendous popularity of the Ingersoll.

coating that tills the pores, cracks and pinholes in 
tin, lolt, wood, steel or iron roofs, and leaves an 
clastic surface that practically becomes a part of the 
material. It Ih easily applied with a brush and will 
not crack, blister, run or peel under any climatic or 
acid conditions.

me all about the roof you’re having trouble with and 
I’ll send enough ROOF-FIX to put it in first-class, 
weather-fighting condition entirely at my own risk. 
You LOSE NOTHING if it fails to stop the leaks— 
you SAVE A LOT if it does. 
ROOF-FIX adds years of service to any kind 
of material. 5 Gala., $4.00; 10 Gals., $7.50;
