<h2> CHAPTER XXVI. DEVELOPMENT OF SHIPBUILDING </h2>
<p>EVOLUTION OF WATER TRAVEL—INCREASES IN SIZE OF VESSELS—IS
THERE ANY LIMIT?—ACHIEVEMENTS IN SPEED—TITANIC NOT THE LAST
WORD.</p>
<p>THE origin of travel on water dates back to a very early period in human
history, men beginning with the log, the inflated skin, the dug-out canoe,
and upwards through various methods of flotation; while the paddle, the
oar, and finally the sail served as means of propulsion. This was for
inland water travel, and many centuries passed before the navigation of
the sea was dreamed of by adventurous mariners.</p>
<p>The paintings and sculptures of early Egypt show us boats built of sawn
planks, regularly constructed and moved both by oars and sails. At a later
period we read of the Phoenicians, the most daring and enterprising of
ancient navigators, who braved the dangers of the open sea, and are said
by Herodotus to have circumnavigated Africa as early as 604 B. C. Starting
from the Red Sea, they followed the east coast, rounded the Cape, and
sailed north along the west coast to the Mediterranean, reaching Egypt
again in the third year of this enterprise.</p>
<p>The Carthaginians and Romans come next in the history of shipbuilding,
confining themselves chiefly to the Mediterranean, and using oars as the
principal means of propulsion. Their galleys ranged from one to five banks
of oars. The Roman vessels in the first Punic war were over 100 feet long
and had 300 rowers, while they carried 120 soldiers. They did not use
sails until about the beginning of the fourteenth century B. C.</p>
<p>Portugal was the first nation to engage in voyages of discovery, using
vessels of small size in these adventurous journeys. Spain, which soon
became her rival in this field, built larger ships and long held the lead.
Yet the ships with which Columbus made the discovery of America were of a
size and character in which few sailors of the present day would care to
venture far from land.</p>
<p>England was later in coming into the field of adventurous navigation,
being surpassed not only by the Portuguese and Spanish, but by the Dutch,
in ventures to far lands.</p>
<p>Europe long held the precedence in shipbuilding and enterprise in
navigation, but the shores of America had not long been settled before the
venturous colonists had ships upon the seas. The first of these was built
at the mouth of the Kennebec River in Maine. This was a staunch little
two-masted vessel, which was named the Virginia, supposed to have been
about sixty feet long and seventeen feet in beam. Next in time came the
Restless, built in 1614 or 1615 at New York, by Adrian Blok, a Dutch
captain whose ships had been burned while lying at Manhattan Island. This
vessel, thirty-eight feet long and of eleven feet beam, was employed for
several years in exploring the Atlantic coast.</p>
<p>With the advent of the nineteenth century a new ideal in naval
architecture arose, that of the ship moved by steam-power instead of
wind-power, and fitted to combat with the seas alike in storm and calm,
with little heed as to whether the wind was fair or foul. The steamship
appeared, and grew in size and power until such giants of the wave as the
Titanic and Olympic were set afloat. To the development of this modern
class of ships our attention must now be turned.</p>
<p>As the reckless cowboy of the West is fast becoming a thing of the past,
so is the daring seaman of fame and story. In his place is coming a class
of men miscalled sailors, who never reefed a sail or coiled a cable, who
do not know how to launch a life-boat or pull an oar, and in whose career
we meet the ridiculous episode of the life-boats of the Titanic, where
women were obliged to take the oars from their hands and row the boats.
Thus has the old-time hero of the waves been transformed into one fitted
to serve as a clown of the vaudeville stage.</p>
<p>The advent of steam navigation came early in the nineteenth century,
though interesting steps in this direction were taken earlier. No sooner
was the steam-engine developed than men began to speculate on it as a
moving power on sea and land. Early among these were several Americans,
Oliver Evans, one of the first to project steam railway travel, and James
Rumsey and John Fitch, steamboat inventors of early date. There were
several experimenters in Europe also, but the first to produce a practical
steamboat was Robert Fulton, a native of Pennsylvania, whose successful
boat; the Clermont, made its maiden trip up the Hudson in 1807. A crude
affair was the Clermont, with a top speed of about seven miles an hour;
but it was the dwarf from which the giant steamers of to-day have grown.</p>
<p>Boats of this type quickly made their way over the American rivers and
before 1820 regular lines of steamboats were running between England and
Ireland. In 1817 James Watt, the inventor of the practical steam-engine,
crossed in a steamer from England to Belgium. But these short voyages were
far surpassed by an American enterprise, that of the first ocean
steamship, the Savannah, which crossed the Atlantic from Savannah to
Liverpool in 1819.</p>
<p>Twelve years passed before this enterprise was repeated, the next steam
voyage being in 1831, when the Royal William crossed from Quebec to
England. She used coal for fuel, having utilized her entire hold to store
enough for the voyage. The Savannah had burned pitch-pine under her
engines, for in America wood was long used as fuel for steam-making
purposes. As regards this matter, the problem of fuel was of leading
importance, and it was seriously questioned if a ship could be built to
cross the Atlantic depending solely upon steam power. Steam-engines in
those days were not very economical, needing four or five times as much
fuel for the same power as the engines of recent date.</p>
<p>It was not until 1838 that the problem was solved. On April 23d of that
year a most significant event took place. Two steamships dropped anchor in
the harbor of New York, the Sirius and the Great Western. Both of these
had made the entire voyage under steam, the Sirius, in eighteen and a half
and the Great Western in fourteen and a half days, measuring from
Queenstown. The Sirius had taken on board 450 tons of coal, but all this
was burned by the time Sandy Hook was reached, and she had to burn her
spare spars and forty-three barrels of rosin to make her way up the bay.
The Great Western, on the contrary, had coal to spare.</p>
<p>Two innovations in shipbuilding were soon introduced. These were the
building of iron instead of wooden ships and the replacing of the paddle
wheel by the screw propeller. The screw-propeller was first successfully
introduced by the famous Swede, John Ericsson, in 1835. His propeller was
tried in a small vessel, forty-five feet long and eight wide, which was
driven at the rate of ten miles an hour, and towed a large packet ship at
fair speed. Ericsson, not being appreciated in England, came to America to
experiment. Other inventors were also at work in the same line.</p>
<p>Their experiments attracted the attention of Isambard Brunel, one of the
greatest engineers of the period, who was then engaged in building a large
paddle-wheel steamer, the Great Britain. Appreciating the new idea, he had
the engines of the new ship changed and a screw propeller introduced. This
ship, a great one for the time, 322 feet long and of 3443 tons, made her
first voyage from Liverpool to New York in 1845, her average speed being
12 1/4 knots an hour, the length of the voyage 14 days and 21 hours.</p>
<p>By the date named the crossing of the Atlantic by steamships had become a
common event. In 1840 the British and Royal Mail Steam Packet Company was
organized, its chief promoter being Samuel Cunard, of Halifax, Nova
Scotia, whose name has long been attached to this famous line.</p>
<p>The first fleet of the Cunard Line comprised four vessels, the Britannia,
Acadia, Caledonia and Columbia. The Unicorn, sent out by this company as a
pioneer, entered Boston harbor on June 2, 1840, being the first steamship
from Europe to reach that port. Regular trips began with the Britannia,
which left Liverpool on July 4, 1840. For a number of years later this
line enjoyed a practical monopoly of the steam carrying trade between
England and the United States. Then other companies came into the field,
chief among them being the Collins Line, started in 1849, and of short
duration, and the Inman Line, instituted in 1850.</p>
<p>We should say something here of the comforts and conveniences provided for
the passengers on these early lines. They differed strikingly from those
on the leviathans of recent travel and were little, if any, superior to
those on the packet ships, the active rivals at that date of the steamers.
Then there were none of the comfortable smoking rooms, well-filled
libraries, drawing rooms, electric lights, and other modern improvements.
The saloons and staterooms were in the extreme after part of the vessel,
but the stateroom of that day was little more than a closet, with two
berths, one above the other, and very little standing room between these
and the wall. By paying nearly double fare a passenger might secure a room
for himself, but the room given him did not compare well even with that of
small and unpretentious modern steamers.</p>
<p>Other ocean steamship companies gradually arose, some of which are still
in existence. But no especial change in ship-building was introduced until
1870, when the Oceanic Company, now known as the White Star Line, built
the Britannic and Germanic. These were the largest of its early ships.
They were 468 feet long and 35 feet wide, constituting a new type of
extreme length as compared with their width. In the first White Star ship,
the Oceanic, the improvements above mentioned were introduced, the saloons
and staterooms being brought as near as possible to the center of the
ship. All the principal lines built since that date have followed this
example, thus adding much to the comfort of the first-class passengers.</p>
<p>Speed and economy in power also became features of importance, the tubular
boiler and the compound engine being introduced. These have developed into
the cylindrical, multitubular boiler and the triple expansion engine, in
which a greater percentage of the power of the steam is utilized and four
or five times the work obtained from coal over that of the old system. The
side-wheel was continued in use in the older ships until this period, but
after 1870 it disappeared.</p>
<p>It has been said that the life of iron ships, barring disasters at sea, is
unlimited, that they cannot wear out. This statement has not been tested,
but the fact remains that the older passenger ships have gone out of
service and that steel has now taken the place of iron, as lighter and
more durable.</p>
<p>Something should also be said here of the steam turbine engine, recently
introduced in some of the greatest liners, and of proven value in several
particulars, an important one of these being the doing away with the
vibration, an inseparable accompaniment of the old style engines. The
Olympic and Titanic engines were a combination of the turbine and
reciprocating types. In regard to the driving power, one of the recent
introductions is that of the multiple propeller. The twin screw was first
applied in the City of New York, of the Inman line, and enabled her to
make in 1890 an average speed of a little over six days from New York to
Queenstown. The best record up to October, 1891, was that of the Teutonic,
of five days, sixteen hours, and thirty minutes. Triple-screw propellers
have since then been introduced in some of the greater ships, and the
record speed has been cut down to the four days and ten hours of the
Lusitania in 1908 and the four days, six hours and forty-one minutes of
the Mauretania in 1910.</p>
<p>The Titanic was not built especially for speed, but in every other way she
was the master product of the shipbuilders' art. Progress through the
centuries has been steady, and perhaps the twentieth century will prepare
a vessel that will be unsinkable as well as magnificent. Until the fatal
accident the Titanic and Olympic were considered the last words on
ship-building; but much may still remain to be spoken.</p>

<h2> CHAPTER XXVII. SAFETY AND LIFE-SAVING DEVICES </h2>
<p>WIRELESS TELEGRAPHY—WATER-TIGHT BULKHEADS—SUBMARINE SIGNALS—LIFE-BOATS
AND RAFTS—NIXON'S PONTOON—LIFE-PRESERVERS AND BUOYS—ROCKETS</p>
<p>THE fact that there are any survivors of the Titanic left to tell the
story of the terrible catastrophe is only another of the hundreds of
instances on record of the value of wireless telegraphy in saving life on
shipboard. Without Marconi's invention it is altogether probable that the
world would never have known of the nature of the Titanic's fate, for it
is only barely within the realm of possibility that any of the Titanic's
passengers' poorly clad, without proper provisions of food and water, and
exposed in the open boats to the frigid weather, would have survived long
enough to have been picked up by a transatlantic liner in ignorance of the
accident to the Titanic.</p>
<p>Speaking (since the Titanic disaster) of the part which wireless
telegraphy has played in the salvation of distressed ships, Guglielmo
Marconi, the inventor of this wonderful science, has said:</p>
<p>"Fifteen years ago the curvature of the earth was looked upon as the one
great obstacle to wireless telegraphy. By various experiments in the Isle
of Wight and at St. John's I finally succeeded in sending the letter S
2000 miles.</p>
<p>"We have since found that the fog and the dull skies in the vicinity of
England are exceptionally favorable for wireless telegraphy."</p>
<p>Then the inventor told of wireless messages being transmitted 2500 miles
across the Abyssinian desert, and of preparation for similar achievements.</p>
<p>"The one necessary requirement for continued success is that governments
keep from being enveloped in political red tape," said he.</p>
<p>"The fact that a message can be flashed across the wide expanse of ocean
in ten minutes has exceeded my fondest expectations. Some idea of the
progress made may be had by citing the fact that in eleven years the range
of wireless telegraphy has increased from 200 to 3000 miles.</p>
<p>"Not once has wireless telegraphy failed in calling and securing help on
the high seas. A recognition of this is shown in the attitude of the
United States Government in compelling all passenger-carrying vessels
entering our ports to be equipped with wireless apparatus."</p>
<p>Of the Titanic tragedy, Marconi said:</p>
<p>"I know you will all understand when I say that I entertain a deep feeling
of gratitude because of the fact that wireless telegraphy has again
contributed to the saving of life."</p>
<p>WATER-TIGHT BULKHEADS</p>
<p>One of the most essential factors in making ships safe is the construction
of proper bulkheads to divide a ship into water-tight compartments in case
of injury to her hull. Of the modern means of forming such compartments,
and of the complete and automatic devices for operating the watertight
doors which connect them, a full explanation has already been given in the
description of the Titanic's physical features, to which the reader is
referred. A wise precaution usually taken in the case of twin and triple
screw ships is to arrange the bulkheads so that each engine is in a
separate compartment, as is also each boiler or bank of boilers and each
coal bunker.</p>
<p>SUBMARINE SIGNALS</p>
<p>Then there are submarine signals to tell of near-by vessels or shores.
This signal arrangement includes a small tank on either side of the
vessel, just below the water line. Within each is a microphone with wires
leading to the bridge. If the vessel is near any other or approaching
shore, the sounds; conveyed through the water from the distant object are
heard through the receiver of the microphone. These arrangements are
called the ship's ears, and whether the sounds come from one side of the
vessel or the other, the officers can tell the location of the shore or
ship near by. If both ears record, the object is ahead.</p>
<p>LIFEBOATS AND RAFTS</p>
<p>The construction of life-boats adapts them for very rough weather. The
chief essentials, of course, are ease in launching, strength in
withstanding rough water and bumping when beached; also strength to
withstand striking against wreckage or a ship's side; carrying capacity
and lightness. Those carried on board ship are lighter than those used in
life-saving service on shore. Safety is provided by air-tight tanks which
insure buoyancy in case the boat is filled with water. They have also
self-righting power in case of being overturned; likewise self-emptying
power. Life-boats are usually of the whaleboat type, with copper air-tight
tanks along the side beneath the thwarts, and in the ends.</p>
<p>Life-boats range from twenty-four to thirty feet in length and carry from
thirty to sixty persons. The rafts carry from twenty to forty persons. The
old-fashioned round bar davits can be got for $100 to $150 a set. The new
style davits, quick launchers in type, come as low as $400 a set.</p>
<p>According to some naval constructors, an ocean steamship can carry in
davits enough boats to take care of all the passengers and crew, it being
simply a question as to whether the steamship owners are willing to take
up that much deck room which otherwise would be used for lounging chairs
or for a promenade.</p>
<p>Nowadays all life-boats are equipped with air tanks to prevent sinking,
with the result that metal boats are as unsinkable as wooden ones. The
metal boats are considered in the United States Navy as superior to wooden
ones, for several reasons: They do not break or collapse; they do not, in
consequence of long storage on deck, open at the seams and thereby spring
a leak; and they are not eaten by bugs, as is the case with wooden boats.</p>
<p>Comparatively few of the transatlantic steamships have adopted metal
life-boats. Most of the boats are of wood, according to the official
United States Government record of inspection. The records show that a
considerable proportion of the entire number of so-called "life-boats"
carried by Atlantic Ocean liners are not actually life-boats at all, but
simply open boats, without air tanks or other special equipment or
construction.</p>
<p>{illust. caption = CHAMBERS COLLAPSIBLE LIFE RAFT}</p>
<p>Life-rafts are of several kinds. They are commonly used on large passenger
steamers where it is difficult to carry sufficient life-boats. In most
cases they consist of two or more hollow metal or inflated rubber floats
which support a wooden deck. The small rafts are supplied with life-lines
and oars, and the larger ones with life-lines only, or with life-lines and
sails.</p>
<p>The collapsible feature of the Chambers raft consists of canvas-covered
steel frames extending up twenty-five inches from the sides to prevent
passengers from being pitched off. When the rafts are not in use these
side frames are folded down on the raft.</p>
<p>The collapsible rafts are favored by the ship-owners because such boats
take up less room; they do not have to be carried in the davits, and they
can be stowed to any number required. Some of the German lines stack their
collapsible rafts one above another on deck.</p>
<p>NIXON'S PONTOON</p>
<p>Lewis Nixon, the well-known ship designer, suggests the construction of a
pontoon to be carried on the after end of the vessel and to be made of
sectional air-tight compartments. One compartment would accommodate the
wireless outfit. Another compartment would hold drinking water, and still
another would be filled with food.</p>
<p>The pontoon would follow the line of the ship and seem to be a part of it.
The means for releasing it before the sinking of the vessel present no
mechanical problem. It would be too large and too buoyant to be sucked
down with the wreck.</p>
<p>The pontoon would accommodate, not comfortably but safely, all those who
failed to find room in the life-boats.</p>
<p>It is Mr. Nixon's plan to instal a gas engine in one of the compartments.
With this engine the wireless instrument would remain in commission and
direct the rescuers after the ship itself had gone down.</p>
<p>LIFE PRESERVERS AND BUOYS</p>
<p>Life-preservers are chiefly of the belt or jacket type, made to fit about
the body and rendered buoyant by slabs of cork sewed into the garment, or
by rubber-lined air-bags. The use of cork is usually considered
preferable, as the inflated articles are liable to injury, and jackets are
preferable to belts as they can be put on more quickly.</p>
<p>Life-buoys are of several types, but those most common are of the ring
type, varying in size from the small one designed to be thrown by hand to
the large hollow metal buoy capable of supporting several people. The
latter are usually carried by sea-going vessels and are fitted with lamps
which are automatically lighted when the buoy is dropped into the water.</p>
<p>ROCKETS</p>
<p>American ocean-going steamers are required to have some approved means of
firing lines to the shore. Cunningham rockets and the Hunt gun are largely
used. The inaccuracy of the rocket is of less importance when fired from a
ship than when fired from shore.</p>
