Joseph Bannon and Thomas Elrod
were friends. Elrod was an educated
man who never secured more than a
man, manufacturer. and got rich.
Elrod's son Henry, as boy, had a
mechanical shop in his fathers cellar
and showed considerable aptitude for
mathematics and mechanics. When
his father died, leaving him nothing,
Henry persuaded Mr., Bannon to give
him a subordinate position in his
works Bannon, who considered both
the boy and his father impracticable.
took Henry into his service under pro-
test, remarking that the boy would
never get beyond the bottom round Of
the ladder. Henry did we'll enough
till his employer caught him making
love to his daughter, Mary Bannon,
whereupon Mr.. Bannon discharged
him.
The morning Henry stepped out Of
the office building at the factory to
hunt another job he saw group of
men, foremost among whom was Ban
non, looking up at the great smoke
stack. Joining them and inquiring
what was the matter, he was Informed
that the stack was leaning to one side.
Indeed, an engineer had just deter
mined that at the top it was forty five
inches out Of plumb.
Here was serious matter From
all appearances scaffOlding must be
erected about the stack, the stack must
be taken down and another built in its
place Indeed, it would be fortunate
tory buildings beneath it, destroying
them. with much valuable machinery.
Bannon was very much troubled. His
engineer told him there was no way
by which the stack could be straight
ened and before leaving the spot he

Elrod went away, trying to concen-
trate his mind upon getting another
position. But the chimney, or, rather,
some method of Strengthening 1t, had

toward evening took pencil and pa

getting up, he went over his figures
to see that they were correct
The next morning, after having slept
only couple Of hours he went to the
Bannon works. Carpenters were just
beginning to erect the scaffolding
around the stack. Henry went into Mr..
Bannon's Office. Bannon, suppoSing
that he had come to protest against
his dismissal, frowned.
"Mr Bannon," he said, 81 don't think
it necessary to take down the stack.
have plan for Strengthening It,"
Bannon looked at him as a general
would look at corporal who was
about to inform him how to save his
army.
IF you wish it, you are welcome to
it," Henry added.
Still there was no word from Ban
non. He was considering whether the
young man had lost his senses.
1.-The base of the stack" continued
Henry, who gathered confidence the
moment he entered upon his plan, ''be
ing square, simplifies the problem. The
stack leans to the east forty five inches
I would remove ten and half inches
Of brickwork at the base Oh the sother
three sides l would insert in the
spaces left blocks Of wood Of equal
size, thus resting the three sides Of the
structure on the blocks. Between the
blocks l would build brick piers six
inches high, leaving space four and a
half inches between the tops of the
piers and the bottom Of the undermined
brickwork. Now, if l can reduce the
height of the blocks by four and halt
inches the gap will be reduced by this
amount and the stack will veer to the
west forty-five inches at the arc de
scribed at the top where the radius (the
chimney is 122 feet"
Bannon's eyes were fixed Oh the
speaker during this statement with
growing interest. He had forgotten the
lesser in the more important matter.
He continued to stare for few mo-
ments after Henry had finished, then
asked:
with the enormous weight (nearly
400 tons) on the blocks, you can't cut
them down and get out the surplus,
II have thought Of that" Henry re-
piled. Il will burn them out"
1t seemed as If 400 tons had been
taken off Bannon's mind.
where are your figures?" he asked.
Henry produced them and waited
while Bannon went over them again
and again.
Come" said the latter when he was
satisfied; you shall have charge Of the
work"
After the successful removal Of the
bricks and the insertion Of the blocks
Henry Elrod marked off the space to
be burned out, set the blocks on fire
and kept them burning evenly If one
burned faster than the others it was
checked till the others
caught up with 1t. Thus they were
kept burning uniformly while the stack
