Asphalt Paint for Tin Roof and Tank. 
Is an asphalt paint good to use on 
tin roofs and the inside of galvanized 
water tank? w. c. E. 
I would not advise using asphalt paint 
for a tin roof as it burns up too quickly. 
You could use it for the inside of the 
galvanized water tank, but I prefer red 
lead. For a new tin roof use red lead 
mixed with lampblack in the proportion 
of 25 pounds red lead, four pounds lamp¬ 
black. Red lead is composed of fine glo¬ 
bules, and when mixed with clear oil 
settles hard at the bottom of the recepta¬ 
cle in which it is mixed. Mixed with 
lampblack, the lampblack forms a coat¬ 
ing over these globules and keeps the red 
lead or holds it up in solution much bet¬ 
ter. For second coat or old roof use 
fatty paint (paint that has stood for 
some time), as it is not so liable to crack 
as freshly mixed paint will after it be¬ 
comes hard. This combination is also 
better for the galvanized water tank than 
asphalt paint. s. 
Value of Lightning Rods. 
What is the practical use of lightning 
rods on a building, and the theory of 
same? Nine people out of ten that I 
talk to on the subject think they are a 
fallacy. L. s. 
Blue Anchor, N. J. 
Lightning is the phenomenon of the 
discharge of electricity from one sur¬ 
charged thunder cloud into another, or 
into the earth. The phenomenon is the 
same as the electric spark, only on a 
much grander scale. When two bodies 
become so charged with electricity as to 
overcome the resistance of the insulating 
air between them, the electric current or 
energy, "juice,” discharges across the in¬ 
tervening space, causing a spark. The 
electric energy, as in lightning, that will 
cause a spark a mile or even two miles 
in length, is almost inconceivable. 
The theory of lightning rod protection 
of buildings is that, if a good conductor 
of electricity be embedded in the earth 
and extended over the building, there will 
be a constant and quiet discharge of elec¬ 
tricity between the cloud and the earth, 
so ns to render impossible the surcharged 
condition that would cause a lightning 
flash. Or, if this should not be alto¬ 
gether prevented, that lightning, seeking 
the course of least resistance, will fol¬ 
low the best conductor of electricity, and 
be carried by the rods past the building 
into the earth. Among men conversant 
with the facts and having a knowledge 
of electrical phenomena, there is no ques¬ 
tion about the practicability and effi¬ 
ciency of lightning rods, provided they 
are properly installed and maintained in 
good condition. I have been told of an 
insurance company that offers to rod 
buildings at a moderate cost and reduce 
the insurance on such buildings to an ex¬ 
tent that will in a very short time cover 
the cost of rodding. 
All metal roofing, spouting, plumbing, 
etc., that is properly grounded, acts as a 
protection against lightning. Probably 
the best protection would be afforded by 
covering the building completely with a 
wire netting having good connections 
with moist earth. Practically, however, 
protection is afforded by a conductor run¬ 
ning along the ridge of a building and 
extending down the middle or sides, or 
better yet, down each of the four cor¬ 
ners into moist earth. Points should rise 
above the higher projections of the build¬ 
ing, such as chimneys, etc., or if these be 
absent or do not well cover the building 
they should be placed at intervals of 20 
to 25 feet along the ridge. 
The main points to observe are sub¬ 
stantial permanent construction, durable 
non-fusible points, and good connection 
with permanently moist earth. Perhaps 
most failures have been caused by im¬ 
proper grounding of rods. They should 
extend several feet into the earth, and 
away from the building into moist earth. 
Connections with water pipes or other 
metal work with deep ground connec¬ 
tions constitute good grounding for rods. 
Stress has been laid on insulation, but 
in the light of more perfect knowledge, 
it seems that this is unnecessary or even 
harmful. Lightning plays many queer 
freaks, and to those unacquainted with 
electrical phenomena, they are unexplain¬ 
able. Rut they are all readily explained 
by a knowledge of the electrical conduc¬ 
tivity of substances, and tbe fact that 
lightning always follows the course of 
least resistance. The practice of light¬ 
ning rod protection is founded on scienti¬ 
fic principles, and is an example of man’s 
mastery of nature through a knowledge 
of nature’s laws. F. L. allen\ 
Putting Up Lightning Rods. 
I have been putting up lightning rods 
for a number of years, and have nailed 
them with cleats close to the buildings. 
One man I rodded for this year, now 
wants me to come and put in dispersers 
so as to hold the cable about two inches 
from the building, he being afraid that 
a stroke might fire the building as rod 
touches all along. Which is correct, 
close to building or held off about two 
inches? J. o. 
Wisconsin. 
It was formerly the practice to carry 
lightning rods through glass insulators 
which held them at some distance from 
the building, but it is now believed to be 
best to fasten them directly to the build¬ 
ing to be protected. The directions for 
putting up lightning conductors issued by 
the U. S. Department of Agriculture, as 
quoted from Farmers* Bulletin No. 367. 
are: “The wires should be fastened to 
the building by galvanized iron staples 
about an inch long; they are not to be 
insulated from it as was once the prac¬ 
tice.” Another way of fastening the 
rods, or wires, to the building is to pass 
them through screw eyes inserted into 
small blocks of wood, which latter are 
nailed to the building. An officially ap¬ 
pointed committee in England, after 
studying the subject of lightning conduc¬ 
tors, reepmmended that they be not kept 
from the building by glass or other in¬ 
sulators, but that they be fastened to it 
by metal fastenings and they further sug¬ 
gest that in many cases it would be ad¬ 
vantageous to carry the vertical rods a 
certain distance away from the walls of 
the building by means of metal holders, 
the object being to do away with the ac¬ 
cumulation of dirt behind the conductors 
and also to do away with the necessity 
of bending them around projecting ma¬ 
sonry, sharp bends in such conductors be¬ 
ing objectionable. m. b. d. 
Measuring Contents of Silo. 
IIow much silage will a silo 28 feet 
high, diameter 20 feet, hold, after it has 
properly settled? I have been filling for 
two weeks and I intend to cut some at 
intervals until it is filled and settled. 
What space do you allow for a ton of sil¬ 
age? J. 11. 
Westchester Co., N. Y. 
According to figures worked out by 
Prof. F. H. King, this silo will hold not 
far from 185 tons. The weight of silage 
per cubic foot varies with the depth, the 
range being 18.7 pounds near the surface 
to 56.4 at 30 feet depth. The average 
weight per cubic foot in a 30-foot silo 
is 39.6 pounds.
