The air rang with benedictions for the King from his devoted subjects. Hope at once returned and the King and Queen were preparing to move on, but the people insisted that they remain, begging that they be not abandoned. The King and Queen wished to visit Torre Del Greco, which is only seven miles distant from Naples, and was also in danger of being wiped out, and the people fled from it in dismay, amid a continued fall of sand and ashes, to points of reputed safety. This village had been eight times destroyed and as often rebuilt. A violent storm of sulphurous rain occurred at San Giuseppe, Vesuviana and Saviano.

The town of Nola, an old place of 15,000 inhabitants, twenty-two miles from Naples, was almost buried under the shower of ashes coming from the crater, which were carried by the wind as far as the Adriatic sea.

The inhabitants of the country in the vicinity of Caserta, a place of about 35,000 people, and termed the Versailles of Naples, were also endangered by cinder ashes and flowing lava.

The village of San Gennaro was partially buried in sand and ashes and several houses were crushed. At that place three persons were killed and more than twenty injured.

Sarno, Portici, Ciricello, Poggio and Morino became practically uninhabitable because of the ashes and fumes, and the people fled from the town. At Sarno three churches and the municipal buildings collapsed. The sand and cinders were six feet deep there and all the inhabitants sought safety in flight.

Sarno is a town of some 10,000 people and is situated about ten miles east of Mount Vesuvius. It contains an old castle, some sulphur baths and manufactories of paper, copper wares, cotton goods and silk fabrics.

Almost equal to the devastation wrought by the lava was the damage done by cinders and ashes, which in incredible quantities had been carried great distances. This has caused the practical destruction of San Guiseppe, a place of 6,000 inhabitants. All but 200 of the people had fled from there and of these 200 who had assembled in a church to attend mass about 100 were killed.

While the priest was performing his sacred office the roof fell in and all who were not killed were badly injured. These unfortunates were for hours without surgical or medical assistance. The only thing left standing in the church was a statue of St. Anne, the preservation of which the poor, homeless people accepted as a miracle and promise of deliverance from their peril.

A runaway train from San Guiseppe for Naples was derailed, owing to showers of stones from the crater. At some points near the mountain it was estimated that the sands and ashes reached a height of nearly 150 feet.

San Georgio, Cremona, Somma Vesuviana, Resina and other inland and coast towns not mentioned above, also suffered terrible devastation.

The most of the buildings in the villages were of flimsy construction with flat roofs and so were but poorly calculated to bear the weight of ashes and cinders that fell upon them. Inevitably it was found that a considerable number of persons perished by the falling of their homes.

National and local authorities from the first evidences of danger attempted the evacuation of the threatened villages and towns, but adequate means to transport the inhabitants were lacking, although thousands of soldiers with artillery carts had been sent to the places where the sufferers were most in need of assistance.

At many places the people were suffering from panic and a state of great confusion existed, which was added to by superstition. Some of the parish priests refused to open their churches to people who tried to obtain admittance, fearing that an earthquake would destroy the buildings when full of people and thus increase the list of disasters.

Crowds of women thereupon attacked the churches, pulled down the doors and took possession of the pictures and statues of the saints, which they carried about as a protection against death.

Many people camped along the roads and in the fields, where they thought they would be safer than in the towns, defying the elements, though nearly blinded by ashes, wet to the skin by rain and terrorized by the gigantic curved flaming mass above, resembling a scimitar ready to fall upon them.

The atmosphere during the eruptions was oppressive and yellow with ashes from Vesuvius, causing a feeling of apprehension regarding what the future may hold in store for this city and its vicinity. The volcano was completely hidden in a dense mass of cinder-laden smoke, the only other signs of activity being frequent and very severe detonations and deep rumblings.

All the trains from and to Naples were delayed owing to the tracks being covered with cinders and telegraphic communication with all points was badly congested.

An excursion steamer attempting to reach Naples from the island of Capri had to return, as the passengers were being suffocated by the ashes.

The quantity of ashes and cinders thrown during the eruptions was unprecedented. An analysis showed this discharge to be chiefly composed of iron, sulphur and magnesia. When dry the whole region seemed to be under a gray sheet, but after a fall of rain it appeared to have been transformed into an immense lake of chocolate.

During the activity of the mountain several new craters had opened, especially on its north side and from which streams of lava flooded the beautiful, prosperous and happy land lying on the southeast shores of the Gulf of Naples.

The whole of Vesuvius district as far as Naples, Caserta and Castellammare became one vast desert. The high cone of the volcano was almost entirely destroyed having been swallowed up, so that the height of the mountain is now several hundred feet less than formerly. Its falling in caused a great discharge of red hot stones, flame and smoke.

Professor Di Lorenzo, the scientist and specialist in the study of volcanoes, estimated that the smoke from Vesuvius had reached the height of 25,000 feet. After one of the eruptions ashes from Vesuvius were noticeable in Sicily which is a large island near the extreme end of the peninsula on which Naples is situated and some 200 miles from the crater.

CHAPTER XXII.
SCENES IN FRIGHTENED NAPLES

Blistering Showers of Hot Ashes – The People Frantic – Cry Everywhere “When Will It End?” – Atmosphere Charged with Electricity and Poisonous Fumes.

FROM the first outburst and glare of the eruption all Naples became aroused and trembled with anticipations of horror, and when the hot ashes from the crater of Vesuvius began to fall in blistering showers upon it the entire populace was seized with a fear, which for days was constant, that at any moment they might be crushed into eternity by the awful outpourings from the cauldron of the mountain which was in truth as veritable an inferno as that pictured by Dante. The streets for days, even up to the subsidence of the eruption, were packed with surging crowds, all of whom were fatigued from fear and loss of rest, yet there was hardly one in all the thousands who had not strength enough to pray to the Almighty for deliverance.

At times the fall of sand and ashes appeared to be diminishing, but in the next instant it came again, apparently in greater force than before. The city became frantic from fear and everywhere was heard: “When will it all end?”

The people deserted their shops, the manufactories were nearly all shut down, while the theaters, cafes and places of amusements throughout the city were all closed. The crowds were in a temper for any excess and it would only require a spark to start a conflagration that would have almost equalled that of Vesuvius itself.

When the coating of ashes and cinders covered the ground and roofs of buildings the people believed that their loved and beautiful Naples was doomed, and would be known thereafter only to archaeologists like other cities which Vesuvius in its wrath had overwhelmed.

All railroad service out of the city was interrupted, the engineers refusing to take out their trains because of the darkness caused by the heavy fall of ashes.

Troops were kept constantly clearing the roofs of buildings of the accumulation of sand and ashes which endangered the structures. The large glass-covered galleries throughout the city, were ordered closed lest the weight upon the roofs should cause them to collapse.

Warships and soldiers which had been ordered to the city did effective service in succoring the most distressed and in the removal of refugees. Their presence was also potent in keeping up public confidence and maintaining order. No danger was too great for the troops to encounter and no fatigue too severe for them. They earned the gratitude and admiration of the people by their devotion to duty and bravery. Not only were they credited with many acts of heroism but they displayed untiring perseverance in searching for the living and the dead among tottering walls, assisting fugitives to reach places of safety, giving aid to the wounded and in burying the dead, and all this while partly suffocated by the ash and cinder laden wind blowing from the volcano.

The employes of a tobacco factory at Naples, thinking the roof was about to fall in fled in panic from the building and communicated their fears to so many people outside that the police were compelled to interfere and restore order. Many persons were injured during the panic.

The prisoners in the city jail mutinied owing to fright and succeeded in breaking open some of the doors inside the building, but were finally subdued by the guards.

King Victor Emmanuel and his Queen, the Duke and Duchess of Aosta and others of the royal household were active in rendering aid. The king placed the royal palace of Cappodimonti, situated above this city, at the disposal of the wounded refugees. Firemen and ambulance corps were sent from Rome to aid the sufferers.

The work of succor was hampered owing to delays to the railway service, which was interrupted by red-hot stones thrown to a height of 3,000 feet falling on the tracks.

Not for a century had Naples been so threatened nor its people thrown into such a state of panic. Men, women and children tramped about the streets, raving that their deity had forgotten them and that the end of the world was in sight.

Thousands of people flocked from the towns and farms on the slopes of the mountain and the problem of feeding and caring for the horde had grown serious. These people were left homeless by the streams of lava, which lapped up all their property in some cases within a half hour after the owners had fled.

Earthquake shocks which shattered windows and cracked the walls of buildings added to the terror and when a shock occurred the entire population rushed to the streets in terror, many persons crying, “The Madonna has forsaken us; the end of the world has come.”

Vessels lying in the harbor rapidly put to sea with hundreds of the wealthy families, who chartered them outright, while many other ships left because of fear of tidal waves similar to those accompanying the terrific eruption of a century ago, which wrecked scores of vessels and drowned thousands of people here.

The atmosphere of the city became heavily charged with electricity, while breathing at times became almost impossible because of the poisonous fumes and smoke. The detonations from the volcano resembled those of terrible explosions and the falling of the hot ashes made life indeed a burden for the Neapolitans.

The churches of the city were open during the days and nights and were crowded with panic-stricken people. Members of the clergy did their utmost to calm their fears, but the effects of their arguments went almost for naught when renewed earthquake shocks were experienced.

While Mount Vesuvius continued active volumes of cinders and ashes emitted from the volcano fell upon the buildings and streets driving the inhabitants of the city into a condition bordering on frenzy. All night people roamed the streets praying and crying that they might be spared.

The collapse of the Mount Oliveto market, in which 200 or more persons were caught, many being crushed beyond recognition and the continuous rain of sand and ashes throughout the city sent terror to the heart of every Neapolitan.

This market covered a plot of ground 600 feet square. The scenes in the vicinity of the ruins were agonizing, relatives of the victims clamoring to be allowed to go to their dead or dying.

The people seemed demented. They surrounded the market, in many cases tearing their hair, cursing and screaming, “Oh, my husband is there!” or, “Bring out my child!” and endeavoring with their own hands to move heavy beams, from beneath which the groans of the injured were issuing.

The cries for help were so heart-rending that even rescuers were heard to sob aloud as they worked with feverish eagerness to save life or extract the bodies of the dead from the ruins.

Some of the people about the market were heard to exclaim that a curse rested upon the people of Naples for repudiating their saints Monday, when Mount Vesuvius was in its most violent mood.

Even with the sun shining high in the heavens the light was a dim yellow, in the midst of which the few people who remained in the stricken towns, their clothing, hair and beards covered with ashes, moved about in the awful stillness of desolation like gray ghosts.

Railway and tramway travel to and from Naples was much hampered by cinders and ash deposits, and telegraphic communication with the towns farthest in the danger zone was also for a time interrupted.

The scenic effects varied from hour to hour during the eruptions. At times in the north the sky was chocolate colored, lowering and heavy, under which men and women with their hair and clothing covered with ashes moved above like gray ghosts. Fort San Martino, as it towered above the town, could only just be seen, while Castel Dell’ovo was boldly marked in light, seeming like silver against the brown sky.

To the south beyond the smoke zone lay smiling, sunny Posilipo and its peninsula, while far away glistened the sea a deep blue, on which the islands seemed to float in the glow of the setting sun. Adding to the strange picture, one of the French men of war, which arrived in the bay of Naples was so placed as to be half in the glow and half obscured by the belt of falling ashes.

From the observatory of Mount Vesuvius, where Director Matteucci continued his work in behalf of science and humanity, the scene was one of great impressiveness. To reach the observatory one had to walk for miles over hardened but hot lava covered with sand until he came to a point whence nothing could be seen but vast, gray reaches, sometimes flat and sometimes gathered into huge mounds which took on semblance of human faces.

Above, the heavens were gray like the earth beneath and seemed just as hard and immovable. In all this lonely waste there was no sign of life or vegetation and no sound was heard except the low mutterings of the volcano. One seemed almost impelled to scream aloud to break the horrible stillness of a land seemingly forgotten both by God and man.

In many of the towns some of the inhabitants went about hungry and with throats parched with smoke and dust, seemingly unable to tear themselves away from the ruins of what so recently were their homes.

The Italian minister of finance suspended the collection of taxes in the disturbed provinces and military authorities distributed rations and placed huts and tents at the disposition of the homeless.

The property loss from the volcanic outbreak has been placed at more than $25,000,000, while some have estimated that the number of persons rendered homeless amounted to nearly 150,000. Probably less than one-half of that number would come near the exact figures.

As an evidence of the widespread and far-reaching influences set in motion by the eruptions of Vesuvius it should be noted that Father Odenbach of St. Ignatius’ college in Cleveland, O., the noted authority on seismic disturbances, reported that his microseismograph, the most delicate instrument known for detecting the presence of earthquakes in any part of the globe, had plainly recorded the disturbances caused by the eruption of Vesuvius. The lines made by the recorder, he said, had shown a wavy motion for several days, indicating a severe agitation in the earth’s surface at a remote point.

CHAPTER XXIII.
VOLCANOES AND EARTHQUAKES EXPLAINED

BY TRUMBULL WHITE

The Theories of Science on Seismic Convulsions – Volcanoes Likened to Boils on the Human Body through Which the Fires and Impurities of the Blood Manifest Themselves – Seepage of Ocean Waters through Crevices in the Rock Reach the Internal Fires of the Earth – Steam is Generated and an Explosion Follows – Geysers and Steam Boilers as Illustrations – Views of the World’s Most Eminent Scientists Concerning the Causes of Eruption of Mount Pelee and La Soufriere.

THE earth, like the human body, is subject to constitutional derangement. The fires and impurities of the blood manifest themselves in the shape of boils and eruptions upon the human body. The internal heat of the earth and the chemical changes which are constantly taking place in the interior of the globe, manifest themselves outwardly in the form of earthquakes and volcanoes. In other words, a volcano is a boil or eruption upon the earth’s surface.

Scientists have advanced many theories concerning the primary causes of volcanoes, and many explanations relating to the igneous matter discharged from their craters. Like the doctors who disagree in the diagnosis of a human malady, the geologists and volcanists are equally unable to agree in all details concerning this form of the earth’s ailment. After all theories relating to the cause of volcanoes have been considered, the one that is most tenable and is sustained by the largest number of scientific men is that which traces volcanic effects back to the old accepted cause of internal fires in the center of the earth. Only in this way can the molten streams of lava emitted by volcanoes be accounted for.

The youngest student of familiar science knows that heat generates an upward and outward force, and like all other forces that it follows the path of least resistance. This force is always present in the internal regions of the earth, which for ages upon ages has been gradually cooling from its poles toward its center. When conditions occur by which it can outwardly manifest itself, it follows the natural law and escapes where the crust of the earth is thinnest.

But something more than the mere presence of internal fire is necessary to account for volcanic action, although it may in a large degree account for minor seismic convulsions in the form of an earthquake. The elements which enter into the source of volcanic eruption are fire and water. The characteristic phenomenon of a volcanic eruption is the steam which issues from the crater before the appearance of the molten lava, dust, ashes and scoria. This accepted theory is plainly illustrated in the eruption of a geyser, which is merely a small water volcano. The water basin of a geyser is connected by a natural bore with a region of great internal heat, and as fast as the heat turns the water into steam, columns of steam and hot water are thrown up from the crater.

One form of volcanic eruption, and its simplest form, is likewise illustrated in a boiler explosion. Observations of the most violent volcanic eruptions show them to be only tremendous boiler explosions at a great depth beneath the earth’s surface, where a great quantity of water has been temporarily imprisoned and suddenly converted into steam. In minor eruptions the presence of steam is not noticeable in such quantities, which is simply because the amount of imprisoned water was small and the amount of steam generated was only sufficient to expel the volcanic dust and ashes which formed between the earth’s surface and the internal fires of the volcano. The flow of lava which follows violent eruptions is expelled by the outward and upward force of the great internal heat, through the opening made by the steam which precedes it.

The two lines of volcanoes, one north and south, the other east and west, which intersect in the neighborhood of the West Indies, follow the courses where the crust of the earth is thinnest and where great bodies of water lie on the shallowest parts of the ocean bed.

The terrific heat of the earth’s internal fires is sufficient to cause crevices leading from these bodies of water to the central fires of the volcano, and the character of the volcanic eruption is determined largely by the size of the crevices so created and the amount of water which finds its way through them. The temperature of these internal fires can only be guessed at, but some idea may be formed of their intense heat from the streams of lava emitted from the volcano. These will sometimes run ten or twelve miles in the open air before cooling sufficiently to solidify. From this it will be seen that the fires are much hotter than are required merely to reduce the rock to a liquid form. From this fact, too, may be seen the instantaneous action by which the water seeping or flowing into the volcano’s heart is converted into steam and a tremendous explosive power generated.

The calamity which befell Martinique and St. Vincent will unquestionably lead to a fresh discussion of the causes of volcanic disturbance. Not all of the phenomena involved therein are yet fully understood, and concerning some of them there are perceptible differences of opinion among experts. On at least one point, however, there is general agreement. At a depth of about thirty miles the internal heat of the earth is probably great enough to melt every known substance. Confinement may keep in a rigid condition the material which lies beneath the solid crust, but if an avenue of escape is once opened the stuff would soften and ooze upward. There is a growing tendency, moreover, to recognize the importance of gravitation in producing eruptions. The weight of several miles of rock is almost inconceivable, and it certainly ought to compel “potentially plastic” matter to rise through any crevice that might be newly formed. Russell, Gilbert and some other authorities regard this as the chief mechanical agent in an eruption, at least when there is a considerable outpouring of lava.

As to the extent to which water operates there is some lack of harmony among volcanists. Shaler, Milne and others hold that substance largely, if not entirely, responsible for the trouble. They point to the fact that many volcanoes are situated near the coast of continents or on islands, where leakage from the ocean may possibly occur. Russell, on the other hand, regards water not as the initial factor, but as an occasional, though important, reinforcement. He suspects that when the molten rock has risen to a considerable distance it encounters that fluid, perhaps in a succession of pockets, and that steam is then suddenly generated. The explosive effects which ensue are of two kinds. By the expansion of the moisture which some of the lava contains the latter is reduced to a state of powder, and thus originate the enormous clouds of fine dust which are ejected. Shocks of greater or less violence are also produced. The less severe ones no doubt sound like the discharge of artillery and give rise to tremors in the immediate vicinity. In extreme cases enough force is developed to rend the walls of the volcano itself. Russell attributes the blowing up of Krakatoa to steam. The culminating episode of the Pelee eruption, though not resulting so disastrously to the mountain, would seem to be due to the same immediate cause. To this particular explosion, too, it seems safe to assign the upheaval which excited a tidal wave.

The precise manner in which the plastic material inside of the terrestrial shell gets access to the surface, is not entirely clear. Nevertheless, it is possible to get some light on the matter. It is now well known that in many places there are deep cracks, or “faults,” in the earth’s crust. Some of them in the remote past have been wide and deep enough to admit molten material from below. The Palisades of the Hudson are believed to have been formed by such an intrusion, the adjacent rock on the eastern face having since been worn away by the weather or other agents. It has been observed that many volcanoes are distributed along similar faults.

The existence of a chain of volcanic islands in the West Indies suggests the probability that it follows a crack of great antiquity, though the issue of lava and ashes for several centuries may have been limited to a few isolated points. Just how these vents have been reopened is one of the most difficult questions still left for investigation. Given a line of weakness in the rocks, though, and a susceptibility to fresh fracture is afforded. Professor McGee suggests that the overloading of the ocean bed by silt from the Mississippi river or other sources may have been the immediately exciting cause of the recent outbreaks. Other geologists have found a similar explanation acceptable in the case of eruptions elsewhere. The theory has much to commend it to favor.

The Martinique disaster already has drawn from geologists and volcanists many expressions of opinion, and explanations of volcanic phenomena which set forth in detail the causes and effects of volcanic eruptions, in particular, and seismic convulsions, in general.

Dr. A. R. Crook, a professor in Northwestern University, has made a special study of volcanoes. He has made an ascent of the two highest in the world, and has climbed many others for purposes of study. He is an authority upon volcanography.

“There are two great circles of volcanoes about the earth,” said Professor Crook. “One girdles the earth north and south, extending through Tierra del Fuego (called ‘land of fire’ because of its volcanoes), Mexico, the Aleutian islands and down through Australia; the other east and west through Hawaii, Mexico, West Indies, Italy (including Mount Vesuvius) and Asia Minor.

“These two circles intersect at two points. One of these is the West Indies, which include Martinique, the scene of this terrible disaster; the other is in the islands of Java, Borneo and Sumatra. On the latter islands there are extinct volcanoes. On the former is the terrible Pelee. It is just at these points of intersection of the two volcanic rings that we expect unusual volcanic activity, and it is there that we find it.

“There has been more or less theorizing as to volcanic disturbances moving in cycles, but it cannot be proved. One fact is established, and that is that a volcano is an explosion caused by water coming in contact with the molten mass below the surface of the earth. This is proved by the great clouds of steam that accompany the action.

“The old theory that the very center of the earth is a molten mass,” he says, “is no longer held.” He asserts the latest idea is that the center of the earth is more rigid than glass, though less rigid than steel. About this there is more or less molten matter, and over all the surface crust of the earth. This molten matter causes the surface of the earth to give, to sag, and form what is called “wrinkling.” When water comes in contact with the heated mass an explosion follows that finds its outlet through the places where there is least resistance, and the result is a volcano.

“There is no part of the earth’s surface which is exempt from earthquakes,” said Professor Crook, “and there is no regularity in their appearance. Volcanic eruptions are almost always preceded by earthquakes somewhere in the circle. Recently there were earthquakes in the City of Mexico in which many lives were lost. As it is impossible to predict when the next will take place, it is also impossible to tell where it will be. It will certainly be somewhere in the line of the two circles.

“All this is of interest as showing that the earth is still in process of formation just as much as it was a billion years ago. We see the same thing in Yellowstone Park. There most decided changes have taken place even in the last eight years. Old Faithful, which used to play regularly every sixty minutes, now does so only once in twice the time.”

With reference to contributions to science, which might be expected from investigations at Martinique, Professor Crook said:

“Even new elements might be discovered, and seismic theories either confirmed or disproved. A volcano always throws off a great variety of materials, hydrochloric and sulphuric acids, iron, silica (sand), sulphur, calcium and magnesium. The lava is of two kinds. That which is easily fusible flows more rapidly than a horse can trot. A more viscous kind cools into shapes like ropes. The latter is common in Hawaii.

“The danger of living in proximity to a volcano is usually well known, but the iron oxides render the soil extremely fertile. This is seen in Sicily about Ætna and Vesuvius. It is seen also in Martinique, where an area of forty miles square was occupied by 160,000 people.

“Owing to the presence of the fumes of chlorine it is probable that many of the victims in St. Pierre were asphyxiated, and so died easily. Others doubtless were buried in ashes, like the Roman soldier in Pompeii, or were caught in some enclosed place which being surrounded by molten lava resulted in slow roasting. It is indeed a horrible disaster and one which we may well pray not to see duplicated. Science, however, has no means of knowing that it may not occur again.”

Professor Robert T. Hill, of the United States Geological Survey, who visited the French West Indies on a tour of scientific inspection, says:

“Across the throat of the Caribbean extends a chain of islands which are really smoldering furnaces, with fires banked up, ever ready to break forth at some unexpected and inopportune moment. This group, commencing with Saba, near Porto Rico, and ending with Grenada, consists of ancient ash heaps, piled up in times past by volcanic action. For nearly one hundred years there has been not the slightest sign of explosion and we had grown to class these volcanoes as extinct.
