| in the circuit, the spring falls into it with a
snap, which In turn releases another spring
falling upon nipple upon which Is a gun cap.
The nipple is Of iron and extends down into
the powder, and the explosion OF the cap In
simultaneously sets Off the compound in the
| bottom Of the can. The machine can be set
anywhere between one minute and thirty-six
hours. When all is ready the operator closes
the lid, fastens 1t with an iron locker, and de-
posits it where he may desire to cause the ex-
| plosion. It can be kicked, rolled around or
hammered, but until the spring falls into the
slot and explodes the cap there Is no danger In
It's handling. By putting the ear close to the
lid the melancholy ttck-tiek OF the clock can be
| six feet. The machine is alright, and water or
| any like fluid has no effect on the explosive
compound, even were it not Theoretically sealed.
It can be securely packed In a barrel of lard. a
barrel of petroleum, box of tobacco, a bag OF
| flour, or with any of those articles Of exDort
which are not likely to attract attention. The
power of such machine depends, Of course.
upon the nature OF the confined space in which
| it is placed.
AN EIGHT-DAY MACHINE.
The most powerful internal machine made rs
| what is known as an ''eight-day machine" Like
the ''ticker," it can, however, be set from one
minute upwards. A machine of this description
recently made by Holgate, Of Philadelphia, was
fourteen inches high, six inches square, and
contained the equivalent of 5000 pounds of gun
powder. 1t can, however, have either square
or spherical shape. It is made of galvanized
arranged that it can be taken out and away
from the machine and connected again at a
moments notice. The operator, If he desire
to divert suspicion. carries the empty can in
his hand and the clock movement In his
coat-tail pocket. The explosion is caused
by detOnatiOn. sliding bar of brass, drawn
by screw attached to the movement. when 1t
| arrives at the slot in the small brass disk,
springs upon delicate glass phial. made of a
full acid and is hermetically sealed, in breaking
allows the acid to escape. This causes the de-
tonatiOn and the explosion follows. The wire
on top Of the movement, which is held in place
by a rubber hand, connects with the cap. The
acid runs into ohlorate Of potash combina-
tion. This machine can be sunk in water or
secreted In any liquor or cOmp0und-ln box of
oranges, keg Of nails or q loaf of bread. The
force Of the explosion would be sufficient to
tear the largest building in the world to atoms.
Little Exterminator." 1t is two inches high
and four inches square, of thin sheet brass,
nickeled on the inside and outside, and has no
lid, only minute hole in one corner. The ma
chine is filled with volatile, the fumes of which
cause instantaneous death. The principle is
the same as that Of the ancient Chinese "stink
pot" used by them so effectively In warfare with
pirates. A thin brass tube runs in through the
small hole in the corner, having upon its outer
end screw cap. Upon the cap is delicate
watch movement. A spring falls into slot and
releases a minute steel spring saw, which is
operated Dy the movement, and saws off the
delicate tube. This establishes direct communl-
cation with the oxygen of the air. which ignites
the volatile The most sickening perfumes pour
out from the box, killing every person within q
radius of one hundred feet. The sensation Of
this volatile is like that caused by cayenne pep
per. There is an intense burning in the mouth,
ears and eyes and around the heart. Respira-
tion is snatched away as II by puff of hot air.
Experiments have been made upon CATS They
die in less than three seconds.
THE CARS HAT.
There is a large class Of Internal machines
known as ''bottle machines" The most ordi-
nary forms are enclosed in pint beer bottles,
which can be conveniently carried in the coat
pocket. The neck Of the bottle is hermetically
sealed with rubber cork, through which runs
| brass tube divided into two parts by thin
metallic disk, usually made Of brass. The top
compartment OF the tube Is shut off from the air
by means OF screw Cap, through which, in turn,
runs key. Also contained in this upper COM
partment Is small vial Of powerful acid. By
turning the key the vial ts broken, and the acid
| falling upon the disk eats into the powder,
which Is packed closely. The time of explosion
depends upon the thickness Of the disk. The
acid, the instant 1t comes In contact with the
powder explodesit! A large number Of these ma
chimes were made for the nihilists, to be used at
| the coronation Of the czar. The newest inyen-
tiOn and one which has met with much favor in
st. Petersburg, is what is called the chat explO-
der" Two exceedingly thin circular disks Of
sheet brass, having layer of powder an inch
thick, are soldered and riveted hermetically to-
gether and sewn In the top of an ordinary hat
The entire weight of the machine, although it
contains the equivalent Of eighty pounds of
powder. is only sixteen ounces. The hat is

two pancakes stuck together. A great many
hand grenades are made in New York They
are hollow balls Of iron, through which runs

the heavy lead button. The button is pressed
breaks vial Of acid, and the acid causes the
explosion. A grenade three and one-half inches
in diameter contains the equivalent Of 100
pounds of powder. The eight-day machine has
been made to contain Greek fire, which is set
off by the clockwork, burning down the building
In which 1t is placed. In this instance there is
no explosion. It is wonderful to what extremes
of ingenuity the inventors OF Internal machines
have gone. Machines have been and are being
made In the shape Of chunks Of coal. They ex-
piode when thrown on the hre. Holgate has
made novel machine In the shape Of q satchel
The handle connects with vial inside or with
. spring falling into slot. Lifting the satchel
or touching tho handle, explodes 1t. Not long
ago, In New York, machine Of the pancake
pattern was 80 constructed as to be made into
shoe soles.
Walking on the soles for certain time causes
them to explode, and woe be unto the unfortu-
nate pOssessor. The demand for Internal ma
chimes Increases constantly. and from the most
unexpected quarters. There ars living at New
York and Philadelphia representatives of all the
revolutionary societies iii the world. They are
not confined to Europe, bat extend through
Mexico and South America. A considerable
