The Story in Firecrackers and Sky-Rockets[9]

The blaze and noise, indispensable to patriotic celebrations among all

peoples, was produced a century ago in America by simple agencies.

Washington’s Birthday was ushered in by cannon salutes in every

garrisoned place in the United States, and boys the country over built

bonfires as they still do in old New England towns to celebrate the day.

But the Fourth of July was the great hurrah time of the year, when every

youth who owned a gun or could borrow one, brought it into use as a

contribution to the general noise. He might lack shoes and be short of

shot and bullets for hunting, but for this occasion no young man was so

poor as to have failed to lay in a hornful of powder, and at the stroke

of twelve midnight, which began the day, he and his companions blazed

away with guns loaded to the danger point, and kept up their fusillade

as long as ammunition lasted. For demonstrations on a larger scale, a

small cannon was secured if possible, but lacking this, two blacksmith’s

anvils were made to do the same service, the hole in the top of one

being filled with powder, a fuse laid into it and the second anvil

placed as a stopper upon the first before the charge was exploded.

A favorite firearm for celebration purposes was one of the old “Queens

Arm” muskets which were common in country communities, being trophies

captured from the British during the Revolutionary War. One of these

cumbersome flint-lock pieces might be loaded halfway to the muzzle and

fired without bursting, and would roar in the discharge in a way highly

pleasing to patriotic ears.

It was near the close of the eighteenth century that Chinese

firecrackers first came into use in celebrating the American

Independence Day. For many years they were used sparingly and only in

large cities. They had been known in the New England coast cities ever

since the year 1787, when Elias Haskett Derby’s ship of Salem, the first

American vessel to engage in deep-water commerce, returned from her

voyage to Calcutta, China and Isle of France. Among the things she

brought back--more as a curiosity than as an article of cargo--was a

consignment of Chinese firecrackers. Their capabilities in aiding the

uproar on the Fourth of July were quickly recognized, and thereafter

every ship that made the voyage from Massachusetts Bay to India or China

brought back firecrackers with the tea, silks and rice. In time,

rockets, squibs and torpedoes were included in the consignment, but it

was not until the middle of the nineteenth century that their use became

general in America.

The time when the more complicated fireworks, which we owe both to

Europe and the Orient, came into vogue in this country, no one perhaps

could now definitely tell. Their use was known to our seafaring men in

the “forties,” for it was in that decade that Capt. Decimus Forthridge,

of the American brig “Independence,” showed his Yankee pluck and

resource in defeating an attack of Malay pirates with no other armament

than fancy fireworks. During his voyage in the East Indies he had laid

in a supply of fireworks with which to celebrate the Fourth of July in a

manner worthy an American captain. For some reason no ammunition was

available for swivels or muskets, when, in the mid-watch of the night,

two war proas, deeply laden with armed Malays, were seen coming quickly

up on the vessel’s quarter as she lay becalmed off Firabader Point in

the Island of Sumatra. The cry of “All hands on deck to repel pirates”

brought the crew on deck in haste, but without ammunition the chance

that they would beat the enemy off was a long shot compared with the

probability that the throat of every man on board would be cut as a

preliminary to plundering and scuttling the vessel. Even in their

extremity the crew laughed and jeered when the captain ranged them along

the quarter rail with boarding pikes and empty muskets in hand to give

the enemy the idea that they were ready for business, and then, opening

the box of fireworks, he began to shoot rockets and roman candles at the

pirates. If the crew laughed, the Malays did not, and when the captain

of one of the proas was struck by a rocket, both crafts rested oars and

came no nearer. But while Captain Forthridge was attending to these, a

third proa came up unobserved under the port quarter, and the first that

was known of its presence was the attempt of its occupants to board the

vessel by the chains. To make matters worse it was discovered that the

paper wrappings of the fireworks in the box were on fire. While the crew

with clubbed muskets and boarding pikes kept the Malays outside the

rails, Captain Forthridge picked up the blazing box, carried it to the

chains, and while the mate and sailors warded the spears and krises from

him, dropped it into the proa. The box was blown to pieces the minute it

struck, scattering the fireworks through the proa, and with firecrackers

snapping and jumping and fiery serpents running round among their bare

legs, the Malays chose to take their chances with the sharks, and all

hands went overboard into the water at double-quick. A little breeze

came up and the brig drew away from the pirates, leaving the two proas

to pick up those Malays from the water that the sharks had missed.

In the days of the China clippers, those famous ships sailed many a race

from Hong Kong and Canton, with New York as the goal, to get there with

“first tea” and to forestall the Fourth of July market with a cargo of

firecrackers.

In China and the East Indies, fireworks, like “the fume of the incense,

the clash of the cymbal, the clang and the blaze of the gong,” are a

part of the worship of the gods, as well as a feature of coronations and

weddings. China is the birthplace of fireworks. From China the knowledge

of them spread to India, and in both these lands rockets were used as

missiles of war as early as the ninth century. The Chinese war rocket

was a long, heavy affair, fitted at the end with a barb-like arrow, and

to a foe unacquainted with firearms, it must have seemed a formidable

missile. After gunpowder was introduced in Europe, fireworks came into

use on the continent, and the use of both explosives undoubtedly was

learned from the Chinese.

Fireworks were manufactured in Italy as early as 1540, and in France we

have accounts of their employment in great celebrations between the

years 1606 and 1739. Long before this time, some form of rocket, now

unknown, that would burn in water, constituted the famous Greek fire

which struck terror to the hearts of invaders from Northern Europe in

medieval times when the Saracens launched it against their ships. Early

in the present century during the Napoleonic Wars, the rocket perfected

by Sir William Congreve was used in the siege of Boulogne and in the

battle of Leipsic. The conditions of modern warfare have so changed that

the rocket is no longer of practical use in fighting except as a signal.

In case of shipwreck it is often employed to carry a line from the shore

to a stranded vessel. It is noteworthy that while almost every kind of

fireworks is manufactured in Europe and the United States, the small

firecrackers are still imported from China. But larger quantities are

now manufactured in the United States, and it is only a matter of time

when the “Young American” salute will take the place of the Chinese

firecrackers.

It was about ten years before the Civil War that “set pieces” began to

form a part of fireworks celebrations. In those days the most famous

pyrotechnic display in the whole country was given on Boston Common on

the Fourth of July, and the country boy who was so lucky as to see that

display, with the miracle of George Washington’s benign face illuminated

amid spouting flames and a shower of fireballs and rockets, had

something to talk about for the rest of the year.

The American Civil War which did so much toward the modern development

of firearms and munitions of war, brought also a great advance in

pyrotechny, and soon after the close of the struggle, extensive

manufacture of fireworks began in this country, with New York as the

headquarters of the principal firms engaged in the business.

In 1865 the first displays of fireworks in the United States,

illustrating historical events, were made by a company in New York City.

They were the pioneers in this line of displays. Their success was

immediate, and from these displays has grown the successes of today in

pyrotechnics.

Fireworks now enter into the celebration of every important event in our

national, political and business life. The celebrations at Washington,

D. C., at the inaugurations of our Presidents, the coronations of

emperors and kings in lands beyond our borders, are all brought to a

close by brilliant displays of fireworks.

The writer, in visiting the plant of a large fireworks manufacturer,

found that they were turning out large quantities of time fuses and

primers for shrapnel shells for the foreign powers, and are working

night and day on orders for the United States government on aeroplane

bombs and signals. They have also worked out a searchlight projectile

which is arranged to burst in the air, throwing out a number of luminous

bodies that light up the surrounding country and reveal the movements of

the enemy.

All large displays of fireworks are now fired by electricity and every

known color and effect is produced by the pyrotechnist of the present

day.

The water displays are scarcely less varied, consisting of flying fish,

diving devils, prismatic fountains, floating batteries, fiery geysers

and submarine torpedoes, all of which, being ignited and thrown into the

water, go through their stunts as readily as other kinds do on land and

in the air.

From every part of the civilized world, from Mexico, Central and South

America and Europe, orders for fireworks come in increasing numbers to

American firms, who now lead the world in this art. The Philippines will

soon be a customer for them, and with the general opening up of China to

modern civilization, from causes now in operation, it will not be

strange if some day we should supply fireworks to the land of their

origin.

What Makes a Chimney Smoke?

Smoky chimneys are usually caused either by the presence of other

buildings obstructing the wind and giving rise to irregular currents of

air, or by improper construction of the fireplace and adjacent parts of

the chimney.

The first may generally be cured by fixing a chimney-pot of a particular

construction, or a revolving cowl, on the chimney top, in order to

prevent the wind blowing down; in the second case the narrowing of the

chimney throat will generally create a better draft.

The longer a chimney is, the more perfect is its draft, provided the

fire is great enough to heat the column of air in it, because the

tendency of the smoke to draw upwards is in proportion to the difference

of weight between the heated air in a chimney and an equal column of

external air.

The first we hear of chimneys, for the escape of the smoke from a fire

or furnace, is in the middle ages.

[Illustration: FLOATING DRY DOCK “DEWEY”

This dry dock, which is capable of floating the largest battleship, was

towed from Sparrow’s Point, Maryland, to Olangapo, Philippine Islands, a

voyage of 13,000 miles. In operation, the dock is sunk by admitting

water into its tanks until the ship can be floated in. The water is then

pumped out and the dock with the ship inside rises to the proper level

as shown.]

[Illustration: U. S. BATTLESHIP “MISSISSIPPI” IN DRY DOCK AT LEAGUE

ISLAND]

What are Dry Docks Like?

Although divers are able to go down under the water to examine the

bottom of a ship while it is afloat, it is usually necessary to have it

up on dry land when thorough inspections or repairs have to be made. So

a berth something like a huge box stall in a stable is built, with the

part where a horse would stand in the stall full of water, and a door,

either made like swinging gates opening in the middle, or a caisson

which is operated up and down like a window, at the end. The ship is

floated into the dock and then after the door is shut to prevent any

more coming in, all of the water is pumped out until the vessel rests on

a lot of great big wooden blocks and supporting props with which the

bottom and sides of the dock are lined. Supports are also placed between

the vessel and each side of the dock. Then, when the work has been

finished, and the ship is ready to go to sea, water is let back either

by pumping it in or else by gradually opening the door at the end, and

the vessel is able to float out into the river or harbor again.

Although all of the navy yards and some private corporations in this

country have docks of this kind, they are not of as much importance here

as in England, where they are used, without pumping out the water, for

the loading and unloading of vessels, because of the very great rise and

fall of the tides there straining and otherwise damaging ships tied up

to ordinary docks.

There are nine important navy yards in the United States, located at

Brooklyn, N. Y.; Boston, Mass.; Portsmouth, N. H.; Philadelphia, Pa.;

Portsmouth, Va.; Mare Island, Cal.; New London, Conn.; Pensacola, Fla.;

Washington, D. C., and Port Orchard, Wash.

There is another kind of dry dock, called “floating docks,” which float

on the surface of the water and may be sunk sufficiently to allow of a

vessel being floated into them, and then raised again by pumping the

water out of the tanks around the sides. They are usually built of iron,

with water-tight compartments, and not closed in at either end. They are

sunk to the required depth by the admission of water into so many of the

compartments, till the vessel to be docked can float easily above the

bottom of the dock, and then they are raised by pumping out the water

until the ship can be propped up as in the land dry dock.

Why does a Lightning Bug Light Her Light?

The lightning bugs or fireflies which are seen so often on summer

evenings in the country and among the trees in the parks of the city,

are similar to the species of beetle called the glowworm in Great

Britain, although the glowworm there does not give as much light as the

firefly in America.

In reality it is only the female which is the lightning bug, for the

male is not equipped with any lighting power. He has the bad habit of

going out nights, and so the female has had to make use of her ability

to make part of her body shine with a sort of a phosphorus green light

in order to show him the way home, very much as a dweller in a

poorly-lighted street keeps a light in the window or on the porch to

guide visitors or the late home-comer to the proper house. She seems to

possess the power of moderating or increasing the light at will.

The most brilliant fireflies are found only in the warmer regions of the

world. The ordinary firefly to which we are accustomed gives off a very

much brighter light if placed in warm water. Fine print may be read by

the light of one kind which is found in the West Indies; in Cuba the

ladies have a fashion of imprisoning them in bits of netting or lace of

a fine texture and wearing them as dress ornaments, and in Hayti they

are used to give light for domestic purposes, eight or ten confined in a

vial emitting sufficient light to enable a person to write.
