Ventilating Dairy Barns 
{Continued from 'page 106 ) 
ample, if the stable bolds 33 cows and the 
distance from the ceiling to cupola is 25 
feet, we take the combined area for 20 
Lid 13, 443 plus 680 or 16 and 17, 545 
plus 579. It should be noted that this 
table gives the total outtake area in 
square inches. If two or four flues are 
used they will each have an area of one- 
Mf or one-fourth this total. 
I The intake flues should generally have 
L total area three-fourths that of the out- 
| takes. There should be from four to six 
of these to each outtake and they should 
be well distributed about the stable so 
that fresh air will be brought in at all 
parts. These should start on the outside 
5 or 6 feet below the ceiling, pass up 
outside of, inside of, or through the 
stable wall and open near the ceiling on 
the inside. It should be remembered 
that the intakes carry cold air and that if 
they are brought up through the wall or 
within the stable the moisture of the warm 
stable air will condense on them if they 
are not well insulated (similar to the out¬ 
take flues). The intakes that are furthest 
from the outtakes may open at the side 
walls, those nearest (10 to 12 feet) the 
outtakes should be carried to the center 
of the barn, if the outtakes are at the side 
walls. Outtakes and intake openings 
should not be close together as this ar¬ 
rangement does not permit the fresh air 
to circulate well through the stable, and 
does allow the cold incoming air to enter 
and chill the air in the outtake flues. In¬ 
take flues should have a damper to control 
the flow of air, and should be screened 
with half-inch mesh hardward cloth to 
prevent the entrance of coarse dirt and 
vermin. The intake flues may be made 
of board or galvanized sheet-iron pipe. 
In the case the latter is used they may be 
fitted with ordinary stove-pipe dampers. 
For the convenience of those who may 
consider using round pipe for flues the 
following table of diameters, areas and 
equivalent squares is inserted.

There still remains to be answered the 
ever-present question, when is the best 
time to install a ventilating system? 
There are so many things to consider that 
doubtless the best answer is:—just as 
soon as we can get at it. The most diffi¬ 
cult part is putting in the outtake flues. 
If they are put in in the early summer the 
barns are usually empty so that there is 
nothing in the way. However, when 
the barn is empty it is a long way from 
the ceiling of the stable to the ridge of the 
barn. A good deal of scaffolding and long 
ladders are needed, and many men get 
weak in the knees with so much open 
space immediately below them. In the 
fall and early winter when the barns are 
full is an ideal time to build the upper 
ends of the outtakes. These can be 
constructed down to the hay after which 
additional sections can be up on as condi¬ 
tions permit. If occasion demands that 
the intake flues be carried to the center of 
the stable, these may be built on the 
mow floor if the barn is empty, or on the 
ceiling of stable if there is fodder in the 
mows. The inside of the stable may be 
ceiled at any time. This is a good inside 
job for a cold winter day. As the work 
need not all be done at once it is not a 
bad plan to build the upper part of the 
outtakes in the early winter and line 
the stable during the cold days that 
follow. 
Dormant Spray for Scale 
{Continued from page 100) 
little insects under the scale move about. 
Bv applying the spray to the tree they 
come in contact with the spray material 
that adhers to the surface ot the bark, ana 
are destroyed. The same with the mites. 
It is impossible to kill the blister mite 
during the summer as at that time it is 
on the inside or between the surfaces of 
the leaf doing it’s damage. 
Advantage of Commercially Prepared Stock 
Where you have only a limited orchard 
it is undoubtedly better, more convenient 
and satisfactory to use the commercially 
prepared lime-sulphur. However, where 
a man has extensive orchards it sometimes 
pays to build a regular “cooker” for the 
preparation of the material. Many 
extensive fruit-growers use the commercial 
material due to it’s convenience and uni¬ 
form strength, the accompanying illus¬ 
tration shows a convenient device for 
doing home-mixing. The caldron is used 
for the actual mixing while the tank is 
used for heating water. 
The materials used consist of 20 pounds 
of lump or caustic lime, 15 pounds of 
sulphur and 50 gallons of water. It is 
most easily prepared by using steam as a 
heating agent where very large quantities 
are used. However, a large iron kettle is 
permissable as long as the ingredients are 
constantly, vigorously and thoroughly 
stirred during the entire time they are 
cooking. Place the lime in the kettle and 
add a few gallons of the hot water to 
start the lime slaking. Do not add the 
water so rapixuy tnat you arown tne lime. 
When the lime starts slaking, add the 
sulphur gradually, sitrring the mixture 
vigorously and constantly. Add about 
another dozen gallons of water and boil 
hard for an hour. Then dilute with more 
hot water until there are fifty gallons. 
It is well to fill the kettle with fifty gallons 
of water before you proceed to get the 
fifty-gallon mark. 
The solution is applied while it is hot. 
However, before it is applied be sure 
to strain it carefully as the material 
contains much sediment. If you fail 
to do this you will experience all 
kinds of trouble with nozzles becoming 
clogged.
