Heating a Small Greenhouse 
A gardener has a sidchill hothouse 10 
ft. wide and 00 ft. long, and was thinking 
of adding another to the .side of it the 
same size, and has a boiler said to be 10 
liorsepowei. Is it not larger than is 
necessary? There is au engine that goes 
with it. I thought I might rig a wood 
saw’ and feed grinder, and run all with 
it. Will some of The It. N.-Y. readers 
give me some advice? j. l. m. 
Greenville, Pa. 
.T. L. M. has a 10 horsepower boiler 
that he wishes to use to heat two green¬ 
houses each 10x60 ft. long, and at the 
same time operate a circular saw and 
feed grinder. This is entirely feasible, 
though it may be possible that he wall 
not have sufficient power to operate the 
feed mill and heat the houses during a 
very cold night. During the daytime, 
whenever the' sun shines, even in cold 
weather, the greenhouses will require 
very little or no heat, when the entire 
steam production capacity may be used 
for power. 
Where a boiler is used for carrying 
high pressure steam and used for heating 
at the same time a pressure-reducing 
valve is installed so that the steam is 
reduced to several pounds’ pressure be¬ 
fore it enters the heating pipes, then a 
pump is necessary t<> again force the 
condensation back to the boiler. The ex¬ 
haust steam from the engine could be 
carried into the heating pipes, and the 
pump could be arranged to return this 
condensation to the boiler, though some 
back pressure on the engine would likely 
result. Where an installation of this 
type is used a vacuum pump is installed 
to keep the radiating pipes clear of con¬ 
densation. then the boiler pump returns 
it to the boiler. You could also pipe the 
houses carefully so that the high pressure 
could be admitted direct to the heating 
coils, though this high pressure heat 
would reduce the moisture in the house 
very rapidly, as the temperature of the 
steam at. SO lbs. pressure would be about 
320 degrees. 
Another method would be to put a good 
dependable valve—preferably a Jenkins 
disk—on the outlet of the boiler on the 
main going to the greenhouse, so that 
this valve could be closed when the en¬ 
gine is in use, the steam for engine being 
taken from another opening in either the 
boiler or the flow pipe on the boiler side 
of the valve. Another valve of the same 
make should be placed on the return 
line where it enters the boiler from the 
greenhouse. With these two valves closed 
you can get up high pressure to operate 
the engine, and when heat is needed in 
the greenhouses the pressure can be al¬ 
lowed ‘'O fall to three or four pounds, 
and tne valves both being opened circu¬ 
lation in the heating coils will follow. 
By the latter method the heating and 
the engine would have to be run sepa¬ 
rately. and the heat in the houses could 
be maintained more uniformly with an 
automatic pressure regulator on the 
boiler to control the dampers. As these 
regulators are operated by a rubber 
diaphragm it would be very necessary to 
have a valve in the pipe connecting it to 
the boiler, which would have to be closed 
whenever the pressure would be increased 
over 5 or 10 lbs. 
When I started in the greenhouse busi¬ 
ness I was night as well as day fireman, 
and unfortunately we heated wth steam, 
though our boiler was of ample size, and 
during moderate weather, with the auto¬ 
matic regulator, the tire could not be 
banked off with anthracite coal, and 
would maintain steam all night. In cold 
weather I had to look at the fire once 
during the night. With hot water, as 
at present installed in most small houses, 
it is much easier to maintain the desired 
temperature with very much less atten¬ 
tion to the fire. elmer j. weaver. 
Grafting Peony Roots 
The tree peony is propagated by root¬ 
grafting on roots of the herbaceous peony. 
How is it done? When is the proper sea¬ 
son? Is there any special sort of her¬ 
baceous peony roots that must be used? 
N. J. Y. 
Peony roots should be grafted during 
August, and should be placed in frames 
during the Winter and transplanted to 
the open ground in the Spring. All eyes 
should be removed from the roots to be 
grafted, and then a single eye inserted 
from the variety desired. The veneer 
method would possibly be best, as this 
method is usually resorted to in working 
over herbaceous plants—especially in the 
greenhouse. After the bud is inserted tie 
with raffia, and possibly a small portion 
of sphagnum moss tied over the union will 
assist in the retention of moisture. Any 
good strong-growing roots should answer.
