A spark from the pipe had Ignited some

Innpector Wolf of the bureau of combus

undoubtedly due not to the fact that those
In-authority did not prepare rules provid

"There are no doubt placea In which high

of that allowed by the law," Inspector Wolf
continued. "I have been spending days and

such, violations have been reported.
"Hut so long as building operations con

discovery Is generally mude at the cost
of an explosion that wrecks the building,
Its value Is a problem that Is left for the
Investigator who follows.
One of the earlier Du Ponts while show

In Delaware was killed In one of tlio retort
rooms. A man who had been In the room

something happened In a minute, or per
haps a second, that brought Instant death
and destruction.
Whllo a Are which destroyed a pier In
Hoboken In May, 1901, was In progress
a carload of dynumlte was pulled out, a
mass of flames. It was rushed, blazing
fiercely back Into tho yards, water wa
turned on, and flames were extinguished.
There was no explosion.
Yet a spark from a passing locomotive
falling into a brush heup against a
magazine at the Laguna Pain, Ariz., caused
an explosion In which 1,000 pounds of
powder and dynamite were exploded, caus
ing great damage to property and serious
Injury to many persons.
A powder wagon containing 3,000 pounds
of dynamite was struck by a passenger
train at a crossing near St. Louis, Mo.
The wagon was demolished, the mule at
, tached to It was killed and dynamite was
scattered all over the right-of-way. But
there was no explosion.
, At Jelllco, Tenn., fifteen persons were
said to have been killed and many Injured
by tho explosion of a car of dynamite.
An Investigation showed that the car had
been shot Into by a person using one of
the powdes cards ns a target.
Shooting Into dynamite seems to be ono
of the sure and certain ways of causing
an explosion. The records are full of ac
counts of catastrophes caused by Ignorant
people shooting at the magazines.
The explosion of three cars of dynamite
at Johannesburg, South Africa, In which
a score of peoplo were killed, was laid to
a stray bullet. Boys shooting Into old
buildings that were formerly used fur
storing explosives have on several occa
sions been credited with lessening trie
tramrj population.
The desire of all experimenters In high
explosives Is to make one that shall have

on the hot Iron pipe. Well, nitro
glycerine that drops from the height of a
foot onto a hot metallic surface will ex
plodeyou can try this yourself by drop
ping a little on the top of a stove and as
a result a good many thaw houses come to
a sudden and unexpected end.
"The method which Is employed here Is
to have a small building heated by steam
or hot pipes. The pipes or radiators are
placed at one end of the room and en
cased In such a manner that It Is not possi
ble for any one to put dynamite where It
can touch them or where any drop of nitro
glycerine which might exude from the
cartridges would come in contact with the
pipes or radiators and so possibly cause
an explosion.
"One of the most remarkable Incidents
In the thawing line Is reported in an
Hngllsh blue book of 1905. A farmhand at
Wheatley, near St. Paul, Minn., drank a
small bottle of nitroglycerine on a wager.
He was found afterward by the roadside
frozen to death. The corpse was placed In
an out-bulldlng near a stove, In order that
It might be thawed, when the nltroglyi erlne
exploded and wrecked the building.
"Dynamiters hear some strange stories.
One that was told mes happening in Lus
ted, Ore., was of a man who In trying to
kill a dog fastened him to a tree, tied a
dynamite cartridge to the dog's tall and ran.
"But the dog broke loose and followed
him. The man took refuge in the houso,
and opened up a fusillade of household
utensils to drive the beast away. The unl
mal retreated beneath the house, where the
cartridge exploded, doing nlmost as much
damage. t tle inun as to the dog.
"But nitroglycerin!) is a queer stuff, nny
wuy. About the only thing that I have
learned for sure about It after being around
the works where It la made is that It blows
out the walls of buildings when It explodes,
while the powder blows off the roof.
. "For that reason you wl)l find around a
nitroglycerine house an earthwork that
makes It look like a small fortress. When
ever there Is an explosion '"sou can look
over the walls of this rampart and about
all that yau can see of what wus there
before Is a lot of kindling wood piled up
somewhat recklesslly In the center of the
space.
"People who work with the dangerous
stuff seem to get mighty careless In Its
use. I remember of a gang of workmen
over In New Jersey who were playing cards
at a table where one of the legs was too
short.
"Ono of the fellows thought to remedy
this by putting a piece of dynamite, which
was the most convenient tning ai nana,
under It. It was all light until tho dis
cussion became heated and they began to
pound on the table. When thu smoke
cleared away there were several missing
arms und leys and other portions of
anatomy.
"Grumplness Is the worst fault of these
workers. Whenever a man gets grumpy
the best thing that can happen to him Is to
get fired. Just out of pure cussedness you
will find thut fellow beginning to bring
knives and pieces of metal Into the works
In strict violation of orders. Just na likely
us not you will find him hiding about him
self n plre and matches and at noontlms
ho will be out smoking under a tree talk
ing to himself.
"I don't know Just why this Is. It la
certainly not caused by nervous strain,
for these men working every day In the
greatest danger, apparently have no Idea
of fear as the ordinary person understands
It. On the other hand, a man who Is dally
exposed to peril In his work In the factory
will go all to plepes over some perfeotly
absurd thing outside.
"This lost winter on a ferryboat crossing
the Delaware were a number of people em
ployed In the nitroglycerine works. The
bn.it got stuck In the Ice and most of the
passengers got off without much remon
strance and walked to the shore. But
every one of those nitroglycerine work
men was afraid to leave the boat, and
they spent part of the night there rather
than take the risk of going over the Ice.
"A big follow who carries cartridges of
plant gelatine down into submarine works,
w hich most anybody would consider as the
most dangerous employment in the world,
was down at one of the nitroglycerine
factories. He wanted to see, he said, how
the stuff that ho handled was made.
"After ho hnd been throunh the plant he
went up to one of tho workmen and said:
" 'How much do you get a day hereT "
" 'Two dollars and a half," was the reply.
" 'Why, I wouldn't stay around here an
other day for $250,000,' said the big fel
low, and he went happily back to his
gelatine toting."

"Winter is the open season ton dynamite

charge of a thawing house at the Pennsyl
vania tunnel excavation. "Dynamite freezes

Fahrenheit, and If you want to do any

Each year the small electric motor finds

all attempts at cataloguing and more ex

B. Garland of Anaonla. Conn, former su
perintendent of the fire, alarm system. He
has been employing his period of recupera
tion from an nccldent which happened to
him several weeks ago to carry out experi
ments along this lire.
Mr. Garland's recent demonstration of
the importance of the discovery of wire
less telegraphy is a result of recent ex
periments along this line carried on by
some eminent French electricians. Al
though his apparatus was somewhat crude,
which affected his results, the experiment,
he believes, proved beyond reasonable
doubt that he could produce electrical
waves of a high voltage and transmit
power through the ulr without any direct
communication.
In this experiment ten dry cells were
used, although a storage battery could be
employed. Fifty foot from these cells In
his house an Induction coll was placed and
connected with an ordinary Incandescent
lamp. One side of the secondary, or high
tension, winding of this coil was grounded
with a gasplpe, while a condenser was
bridged across the two pole plena of the
primary circuit. The other side of the sec
ondary circuit was Ubed as the aerlul con
ductor. At this distance Mr. Garland found that
the ten cells would produce on the primary
winding of the Induction coll a voltage of
about fifteen, which varied ' c.r.'.y slightly
as the distance between the cells and the
Induction coll was decreased The lamp
employed was an ordinary Incandescent
street lamp of twenty-five ca ndlepower.
One conductor of this lamp was grounded
to a water pipe and a suitable resistance
cut In on the other pole leading to the
aerlul conductor, which consisted simply
of the brass Jiole pieces attached to tho
lamb.

Elect rlo power from sunlight appears
more worftlerful than harnessing the
streams or wind. Yet we know something
of the vast heat of the sun.
Solar engines for operating pumps have
bwn in use In different parts of the earth
for several years now, and their value la
warm climates, where the number of day
of clear sunshine averages high, must
steadily Increase, One of the most suc
cessful of these solar machines, says a
writer In Bt. Nicholas, is located near Log
Angeles to irrigate fruit land. An auto
matic stand carrying great reflectors fol
lows the course of the sun as regularly as
the best telescope ever made, and the sun's
rays sre thus reflected on a central point,
where the boiler of a small engine is lo
cated. Within an hour after sunrise th
heat of the sun raises the temperature oi
the water to the boiling point, and thug
creates stoam: and the pumping machinery
begins its day's work and keep it up until
sundown.
The power of the sun for heating has
only leen faintly appreciated by scien
tists In the pat. but ,th prediction Is
made now that If all the coal should give
out we would soon be able to run much
of our machinery from the povrer of the
sun. With Boo mirrors properly arranged to
focus thi rays upon one point, a tempera
ture of more than 1,000 degrees haa been ob
tained. This almost equals one-fifth the
hlstw-ht toniporuturo recorded by the elec
tric furn io which is considered today the
most powerful heating apparatus ever dis
covered. As there Is no limit to the num-ttt-r
of mirrors that may be employed, and
as the Intensity of the heat Increases In
proportion to the number of rays reflated
by the mirrors, It is conceivable that a
temperature may be obtained In time that
will surpass anything ever dreamed of in
the past or prestnt.
Hitching the sun to run electiia motors
for furnishing light and cw'r for our
homes and factories Is the very latest
achievement of the modern work of har
neeslng the elements to do man's work;
and one squars yard of sunshine fn the
tropica may represent, on the average, ooe
horse power.
