[Ill.u.s.tration: THE TOWER OF LONDON.]

Twelve bridges other than railroad bridges cross the river Thames within the city boundary. The largest manufacturing interest in London is that of the breweries, wherein eleven million bushels of malt are annually consumed.

Buckingham Palace, the town residence of Queen Victoria, occupies a location facing St. James's Park, and is a s.p.a.cious building, but of no architectural pretention. The famous tower of London, according to tradition, was originally built by Julius Caesar, and is situated on the east side of the city, on the left bank of the Thames. It is no longer used as a prison, but is a national armory and museum of warlike implements of antiquity. London has an underground railway running beneath the streets and houses by means of tunnels, and also through cuttings between high walls, forming a complete belt round the inner sections of the city, while branch lines diverge to the suburbs.

Statistics show that the railway company which controls the line conveys about eighty millions of pa.s.sengers annually, at an average rate of twopence each, or four cents of our American currency, per trip. There are over fifty regularly licensed theatrical establishments in the city.

The charitable organizations of London are on a scale commensurate with its great wealth and population, while its educational facilities are on an equally extensive scale.

Travellers who land in England at Holyhead, on their way to London, go to the great metropolis by way of Chester, which is one of the most interesting cities in Great Britain. It has a population of a little over thirty thousand, and retains more of its ancient character than any other city of England. The old defences have been carefully preserved, and charming views of the surrounding country may be enjoyed from the promenade which follows the course of the wall. Many of the houses are so constructed that the second floors form a series of continuous galleries or covered ways for foot pa.s.sengers, known as the "Rows."

There is an ancient cathedral here of considerable interest, rendered familiar by the numerous pictures of its several parts which have been so often published. One of the most popular race-courses in England is situated just outside of the city walls of Chester. There is a fine modern Gothic residence in the environs, belonging to the Marquis of Westminster, known as Eaton Hall, and which people travel long distances to see, as it is considered one of the finest structures of its kind in the kingdom.

A railway journey of a hundred miles from London takes us into a beautiful portion of rural England, to that pleasant watering-place, the town of Leamington, where some natural springs exist which are believed to possess certain medical properties. There is a resident population of twenty thousand, which is largely increased during the attractive season of the year. This neighborhood is not only remarkable in a historical point of view, but also for the rural beauty and quiet charms of its scenery. There is here a public garden of twelve or fifteen acres in the middle of the town, under a high condition of cultivation.

It is but a short trip by rail from Leamington to Kenilworth Castle, or rather to its ruins. We need not narrate the historical a.s.sociations of this place. Scott, in his admirable novel, "Kenilworth," has rendered the reading world familiar with it. The bare and crumbling walls are an eloquent monument of the days of chivalry. The castle is said to have been sufficiently extensive to have accommodated on one occasion Queen Elizabeth and four hundred lords and ladies attached to her household.

It was left to the charming pen of Sir Walter Scott to fix the history of the time and place upon the memory more effectually than could be done by the pages of the professed historian.

From Leamington we may also make an excursion to Warwick Castle, one of the grandest and best preserved of mediaeval structures to be seen in Great Britain, and which is occupied by the present Earl of Warwick.

This relic of the past, perhaps quite as ancient as Kenilworth, of which only the ruins remain, is in a condition of perfect preservation, and we believe it has never ceased to be occupied by representatives or descendants of the same family. The castle contains a museum of antiquity, including a great variety of armor, battle-axes, swords, flags, and war implements generally, which were used by the ancestors of the present earl. There are some choice paintings in the s.p.a.cious halls, while from the windows views may be enjoyed, fully depicting the beauties of English rural scenery.

Stratford-on-Avon--the birthplace of Shakespeare--is within a short distance by rail: it contains some four thousand inhabitants. Few foreign travellers fail to visit Stratford. We come to the suggestive spot on a bright, sunny day, and hasten at once to the old church where rest the mortal remains of Shakespeare. Just back of this ancient Gothic structure flows the quiet Avon in the same bed where it has glided for centuries. A group of hay-makers lying idly upon the gra.s.s on the opposite bank are gossiping away the noon hour; a fisherman with pole and line is daintily sounding the shady nooks of the peaceful river; a few white swans glide gracefully in the shadow of the overhanging willows, while in the middle distance a flock of sheep nibble the rich green herbage. We find the interior of the church but little superior in architecture and ornamentation to most country churches. The tomb of the poet is in the chancel. Just over the grave, in a niche of the wall, is a bust of Shakespeare, which was placed there shortly after his death, and which is believed to be a good and true likeness of the original. He died at the comparatively early age of fifty-three. We take refreshment at the Red Horse Inn, rendered famous by Washington Irving, stroll thoughtfully through the quaint old village, and visit, with thrilling interest, the house in which Shakespeare was born.

From this remarkable vicinity we take pa.s.sage over the Great Northern Railroad, by way of Preston and Carlisle, finally reaching Edinburgh, the thriving and pleasant capital of Scotland.

It is a peculiarly formed city, being built on three parallel ridges of considerable elevation, and is remarkable for the general excellence and elegance of its architecture. The older portion of the city is situated upon the loftiest of the ridges, and on which the houses rise to the height of nine and ten stories along the edges and on the steep slopes.

The streets in the old town are narrow and irregular. The newer section occupies a lower ridge, being separated from the old by a valley which is improved as a public garden and for business purposes. The public and private buildings are mostly constructed of a white stone resembling marble, which is quarried in the neighborhood. The population numbers about three hundred thousand, occupying a territory which measures just about two square miles. The longest street commences at the Palace of Holyrood and ends at Castle Hill, upon the summit of which is Edinburgh Castle, standing four hundred and fifty feet above the level of the sea.

[Ill.u.s.tration: EDINBURGH CASTLE.]

This might appropriately be called the city of monuments. Among the most prominent are statues to Sir Walter Scott, Nelson, Playfair, Professor Wilson, Allan Ramsay, the Duke of Wellington, and Robert Burns. Scott's monument stands quite by itself on Princes Street, and rises to two hundred feet in height. Few monuments in the world equal this Gothic structure in architectural beauty. The citizens of Edinburgh may well be proud of their numerous educational inst.i.tutions and charitable establishments, in which departments of n.o.ble liberality no city in Great Britain can surpa.s.s the Scotch metropolis. Near by Holyrood Palace are the ruins of the ancient abbey of the same name, founded by David I.

nearly eight hundred years ago. In its chapel Queen Mary was married to Lord Darnley. In visiting the castle on the hill we are shown the small room wherein Queen Mary became the mother of James VI., who was afterwards king of England. The royal infant was lowered from the window of the little chamber in a basket, when friends received it and thus saved it from its scheming enemies.

In the High Street we visit the house where John Knox, the great Scottish reformer, lived. Close by, in White Horse Close, is the inn where Dr. Johnson lodged in 1773, while in the churchyard hard by are the graves of Adam Smith and Dugald Stewart. It is not possible to feel indifferent to such a.s.sociations. No grander figure can be found in the history of the Reformation than that of John Knox. His biography reads like a romance. Whether serving a two years' sentence in the French galleys, enduring a siege in the castle of St. Andrews, being tried for treason by order of Queen Mary, haranguing from the pulpit against what he considered false religionists, or having his steps dogged by a.s.sa.s.sins, Knox never swerved from what he believed to be the path of duty.

In the immediate environs of the city, to the south of Holyrood, are Salisbury Crags and Arthur's Seat, always visited by strangers, besides being a favorite resort of the citizens of Edinburgh. There is a fine road-way which surrounds Arthur's Seat, known as "The Queen's Drive."

Scott made this vicinity of more than pa.s.sing interest by his "Heart of Mid-Lothian," and the local guides point out the spot where Jeanie Deans is represented to have met Robertson. The "Queen's Drive" affords from several points charmingly comprehensive views.

A drive of twenty miles through the hills and plains lying to the southeast of the city will take us to Melrose, a place only noted for its famous ruins of the Abbey. It was founded by David I., in 1136, for monks of the Cistercian order, and rebuilt in an elaborate and elegant style between the reign of Robert Bruce and James IV. It was the finest church, as it is the n.o.blest ruin, in Scotland. Scott has rendered us familiar with it. From here we drive to Abbotsford, the home of Sir Walter, and which is still kept exactly in the condition in which the poet left it on the day of his death. We wander through the house, lingering in the library, sit in the chair before the table where he sat and wrote in prose and poetry; we examine the curious collection of armor and the various historical mementos which he gathered about him, among which are weapons once owned by Rob Roy and the Douglas, and those of other real characters about whom his genius has woven such romantic interest. Abbotsford House is large, imposing, and beautifully situated, the s.p.a.cious grounds which are attached to it sloping gracefully down to the banks of the river Tweed, beyond which rise the beautiful Selkirk Hills.

In travelling about the rural districts of Scotland in the vicinity of Edinburgh, one is impressed by the thrifty appearance of the country, which seems to be cultivated with great care. We see many flocks of sheep. There is not much attempt at what is called gardening, but a few staples in grain are depended upon, and much attention is given to the raising of sheep, horses, and cattle. The men and women are of a strong, vigorous type, hospitable and kindly. The national characteristics of the Scotch exhibit themselves in the simplest transactions. They are a remarkably intelligent and well-educated people; steady-going, plodding, economical, very set in their ways and opinions, being rather slow according to American ideas, but uncommonly sure and reliable.

Glasgow differs from Edinburgh in many respects. Its situation is low, and the view is obstructed by a multiplicity of tall, smoky chimneys, with other tokens of manufacturing industry. It is the most populous city of Scotland, having over half a million of inhabitants, and is located on the banks of the river Clyde. Except in the manufacturing parts of the town, the architecture and streets are fine and attractive. Dressed freestone is the material most commonly used in the construction of the best dwelling-houses and the public buildings. The river is crossed by five n.o.ble bridges,--two of granite, one of iron,--and two are suspension bridges. The city reminds one forcibly of Pittsburgh in America. The chemical works, foundries, and workshops of all kinds, using such quant.i.ties of bituminous or soft coal, create an atmosphere of a dense, smoky character.

Glasgow contains four large and beautifully kept parks. The city is over a thousand years old, but we have no record of its earliest three or four centuries. Situated in the midst of a district abounding in coal and iron, and upon a river which insures it world-wide commerce, maritime enterprise has been a natural result. Here James Watt made his memorable improvements in the steam-engine, and here Henry Bell first demonstrated in the Old World the practicability of steam navigation.

This was in 1812, four years after Fulton's successful experiments upon the Hudson River in this country, but of which Bell seems to have had no knowledge. Glasgow has many handsome and substantial blocks of dwelling-houses. Buchanan Street and Queen Street are both remarkably elegant thoroughfares; the former especially is notable for its large and attractive stores. Argyle Street is very broad and two miles long, one of the finest avenues in Great Britain. Here, as in Edinburgh, there are numerous public monuments, among which we observe the equestrian statues of William III., the Duke of Wellington, in front of the Royal Exchange; and that of Queen Victoria, in George's Square. There is also an obelisk one hundred and forty feet high, erected to the honor of Nelson, besides others of Sir Walter Scott, Sir John Moore, James Watt, Sir Robert Peel, etc.

There are two chimneys in the city designed to carry off the poisonous gases from the chemical works, which are respectively four hundred and sixty, and four hundred and fifty feet in height, the latter carrying off the vapor from St. Rollox, the largest chemical manufactory in the world. These buildings cover fifteen acres of ground, and the works give employment to over a thousand men. Cotton factories are also numerous here, and calico-printing establishments. Beer-brewing is one of the largest branches of manufacture, as it is also in London. In the building of iron steamships the port of Glasgow leads the world. For a long time there was an average of one steamer a day launched on the banks of the Clyde, in the vicinity, though this number is not quite kept up at the present time. Clyde steamers have a high reputation, and are given the preference for durability and general excellence of workmanship.

Greenock, with a population of about fifty thousand, is one of the finest seaports in Scotland, having also a large business in iron ship-building. This was the native place of James Watt, already spoken of, and here we observe an admirable statue reared to his memory. The city is situated a little over twenty miles from Glasgow, on the Firth of Clyde. From here we take pa.s.sage in a steamer across the Irish Sea to Belfast, the princ.i.p.al city of Northern Ireland.

Belfast has a population of about two hundred thousand, and next to Dublin is the most important city of the country. It is comparatively modern, its tall chimneys, large factories, and spinning-mills speaking intelligibly of material prosperity. Queen's College is a large structure in the Tudor style, with a frontage of six hundred feet in length. There is an admirable museum on College Square containing a large collection of Irish antiquities. We also find an excellent botanical garden here, and there are no better school facilities in the United Kingdom than are to be enjoyed in this metropolis of Northern Ireland. From Cave Hill, in the suburbs, an elevation over a thousand feet in height, a most admirable view of the city and its surroundings may be enjoyed, the coast of Scotland being visible on the far horizon.

The streets of Belfast are regular, broad, and cleanly, and many of the public buildings are superb in architectural effect. The city hall, the custom house, the Ulster Bank, and Linen Hall are all n.o.ble structures.

This is the great headquarters of the Irish linen trade.

A short journey of about a hundred miles due south by railway will bring us to Dublin, the capital of Ireland. It has a population of about four hundred thousand, and is situated on the sh.o.r.e of Dublin Bay, with the river Liffey flowing through its centre. It is an attractive city with very beautiful surroundings. There are many grand public buildings, several large parks, a number of interesting old churches, and a cathedral,--St. Patrick's,--connected with which are the a.s.sociations of six centuries. The remains of Dean Swift are buried here. Near by is the house where Thomas Moore, the poet, was born, and not far away is the birthplace of the Duke of Wellington. Dublin has its public library, its museum, its Royal College of Surgeons, and its famous Trinity College, where Goldsmith, Swift, Burke, and many others graduated. It has also many n.o.ble charitable organizations and societies for the diffusion of science. The zoological garden is one of the most extensive in Great Britain. Dublin Castle is near the centre of the city, on slightly elevated ground, containing an armory, a chapel, and various government offices. This city claims great antiquity, having existed as a capital since the days of Ptolemy. It was for centuries held by the Danes; in 1169 it was taken by the English under Strongbow, whose remains lie in Christ Church Cathedral.

From Dublin we take pa.s.sage on board of a steamer for Liverpool, the commercial metropolis of England, which contains about seven hundred thousand inhabitants. It is situated on the river Mersey, four miles from the sea. To the traveller it presents few attractions save those of a great shipping depot, which is unsurpa.s.sed in the department of maritime enterprise.

The moral and physical character of the population, taken in ma.s.s, is rather low, though the city has many inst.i.tutions and a.s.sociations designed to promote intelligence and to fulfil all charitable demands.

The exhibitions of intemperance to be met with upon the streets at all hours forms a disgraceful picture of humanity, in which respect Liverpool seems to be more sadly afflicted than are the lowest sections of London.

From here we sail for Na.s.sau, New Providence, a British possession in the Bahama Islands, lying northeast from Cuba, the largest of the West Indian Islands.

CHAPTER XXIII.

Upon landing at Na.s.sau we find everything quite different from our late experiences in the large European cities, and are brought face to face with nature,--with a tropical race and with tropical vegetation. Instead of palatial edifices we have low native huts, while the people we meet have the bronzed hue of Africans. This island, which was settled by Europeans as early as 1629, contains nearly a hundred square miles. The town has a small free library, several churches, a hospital, and a bank.

It seems singular that an island like New Providence, which is almost without soil, should be so productive in vegetation. It is surrounded by low-lying coral reefs, and is itself of the same formation. In a pulverized condition this limestone forms the earth out of which spring palm, banana, ceba, orange, lemon, tamarind, mahogany, and cocoanut trees, with various others, besides an almost endless variety of flowers. Science teaches us that all soils are but broken and decomposed rock pulverized by various agencies acting through long periods of time.

So the molten lava which once poured from the fiery mouth of Vesuvius has become the soil of thriving vineyards which produce the choice grapes whence is made the priceless Lachryma Cristi wine of Naples. This transformation of lava into soil is not accomplished in the period of a single life.

The luscious pineapple, zapota, mango, pomegranate, citron, custard-apple, and other fruits captivate the palate of the stranger, while the profuseness and variety of beautiful ferns and orchids delight the eye of the northerner. The negroes are mostly engaged in cultivating pineapples, yams, sweet potatoes, and other vegetables, and a large number of the males employ themselves in fishing and gathering sponges.

From this locality comes the largest supply of coa.r.s.e sponge which is used in England and America. There is also a considerable trade carried on in fine turtle-sh.e.l.l, which is polished in an exquisite manner by the patient natives. The Bahama sponges are not equal to those obtained in the Mediterranean. But they are marketable for certain uses, and Na.s.sau exports half a million dollars' worth annually. It is said that sponges can be propagated by cuttings taken from living specimens, which, when properly attached to a piece of board and sunk in the sea, will increase and multiply. Thus the fine Mediterranean sponge can be successfully transported to the coral reefs of the Bahamas.

A short drive or walk inland over smooth roads, formed of smooth, levelled coral rocks, brings us to the extensive pineapple fields, where this handsome fruit may be seen in the several stages of growth, varying according to the season of the year and the purposes of its use. If intended for exportation, the fruit is gathered when well-grown but still in a green state; if designed for canning,--that is, preserving,--the riper it is, the better it is adapted to the purpose.

Great quant.i.ties are put in tin cans carefully sealed for use in this and other countries. The visitor is sure to be impressed by the beauty and grace of the cocoanut-trees, their plume of leaves, often sixty feet from the ground, notwithstanding that the bare stem or trunk is rarely over two feet in thickness.

There are said to be six hundred of the Bahama Islands, large and small, of which Na.s.sau is the capital, and here the English governor-general resides. Many are mere rocky islets, and not more than twenty have fixed inhabitants. The sea-gardens, as they are called, situated just off the sh.o.r.e of the main island, are extremely interesting. We go out a short distance in a row-boat, and by means of a simple contrivance of wood and gla.s.s we can look many fathoms below the surface of the sea. These water-gla.s.ses are easily made, being formed of a small wooden box three or four inches square, open at the top and having a water-tight gla.s.s bottom. With the gla.s.s portion slightly submerged one is able to see distinctly the beautiful coral reefs with their marvellous surroundings. There are displayed tiny caves and grottoes of white coral, star-fishes, sea-urchins, growing sponges, sea-fans, and bright-colored fishes, including the hummingbird fish, and others like b.u.t.terflies with mottled fins and scales, together with that little oddity, the rainbow-fish. The prevailing color of this attractive creature is dark green, but the tinted margins of its scales so reflect the light as to show all the colors of the rainbow, and hence its name.

When bottled in alcohol for preservation, these fish lose their native colors. This unique display is enhanced in beauty by the clearness of these waters, and the reflected lights from the snow-white sandy bottom, which is dotted here and there by delicate sh.e.l.ls of various shapes and colors. One longs to descend among these coral bowers,--these mermaid gardens,--and pluck a bouquet of the submarine flora in its purple, yellow, and scarlet freshness.

The surface life of these clear waters is also extremely interesting.

Here the floating jelly-fish, called from its phosph.o.r.escence the glow-worm of the sea, is observed in great variety, sheltering little colonies of young fishes, which rush forth for a moment to capture some pa.s.sing mite, and as quickly return again to their cover. If we take up a handful of the floating gulf-weed, we find within the pale yellow leaves and berries, tiny pipe-fish, seahorses, and specimens of the little nest-building fishes. Thus this curious weed forms a home for parasites, crabs, and sh.e.l.l-fishes, being itself a sort of mistletoe of the ocean. The young of the mackerel and the herring glide rapidly about in shoals, just below the surface, near the sh.o.r.e, like myriad pieces of silver. Verily there would seem to be more of animal life below than above the surface of the waters, which is not an unreasonable conclusion when it is remembered that the whole surface of the globe is supposed to have an area of about two hundred million square miles, and that of these only about fifty millions are composed of dry land.

Much of the drinking-water, and certainly the best in use at Na.s.sau, as well as on some of the neighboring islands, is procured in a remarkable manner from the sea. Not far from sh.o.r.e, on the coral reefs, there are never-failing fresh-water springs, bubbling up from the bottom through the salt water with such force as to clearly indicate their locality.

Over these ocean springs the people place sunken barrels filled with sand, one above another, the bottoms and tops being first removed. The fresh water is thus conducted to the surface through the column of sand, which acts as a filter, the water being sweet and palatable, as well as remarkable for its crystal clearness. So on the arid sh.o.r.es of the Persian Gulf, where rain seldom falls, and where there are no rills to refresh the parched soil, fresh water is obtained from springs beneath the sea. There it is brought to the surface by employing divers, who descend with leather bags. The mouth of a bag is placed over the bubbling spring, quickly filled and closed again, being then drawn to the surface by persons awaiting the signal from the diver, who then hastens to rise for needed air. There is no mystery as to the source of these springs. The rain falls on the distant mountains, and finding its way through the rocky ledges, pursues its course until it gushes forth in the bed of the gulf.

A fortnightly steamer from New York, bound for Cuba, touches at Na.s.sau on the southward trip to leave the mail, and we will avail ourselves of this opportunity to visit the "Queen of the Antilles," as this island is called. At first we steam to the north for half a day, in order to find a safe channel out of the Bahamas, where there is more of shoal than of navigable waters, and as we do so, we leave many islands behind us inhabited only by turtles, flamingoes, and sea-birds. But we are soon steaming due south again towards our destination, namely, the island of Cuba, five hundred miles away. San Salvador is sighted on our starboard bow (right-hand side), the spot where Columbus first landed in the New World. It will be found laid down on most English maps as Cat Island, and is now the home of two or three thousand colored people, the descendants of imported Africans. The island is nearly as large as New Providence. It is said that the oranges grown here are the sweetest and best that are known. The voyager in these lat.i.tudes is constantly saluted by gentle breezes full of tropical fragrance, intensified in effect by the distant view of cocoanut, palmetto, and banana trees, clothing the islands in a mantle of green, down to the very water's edge. As we glide along, gazing sh.o.r.eward, now and again little groups of swallows seem to be flitting a few feet above the waves, then suddenly disappearing beneath the water. These are flying-fish enjoying an air-bath, either in frolic or in fear; pursued possibly by some dreaded enemy in the sea, which they are trying to escape.

It is interesting to remain on deck at night and watch the heavens as we glide through the phosph.o.r.escent sea. Is it possible that the moon, whose light renders objects so plain that one can see to read small print, shines solely by borrowed light? We know it to be so, and also that Venus, Mars, and perhaps Jupiter and Saturn shine in a similar manner with light reflected from the sun. It is interesting to adjust the telescope, and bring the starry system nearer to the vision. If we direct our gaze upon a planet, we find its disk or face sharply defined; change the direction, and let the object-gla.s.s rest upon a star, and we have only a point of light more or less brilliant. The gla.s.s reveals to us the fact that the "star-dust" which we call the Milky Way is an acc.u.mulation of innumerable single stars. Sweeping the blue expanse with the telescope, we find some stars are golden, some green, others purple, many silvery white, and some are twins. Our use of the words "first and second magnitude" relates mainly to distance. It is most likely only a question of distance which regulates our vision or capacity for seeing, and which makes these "lamps of the sky" look larger or smaller to us.

When the lonely lighthouse which marks Cape Maysi, at the eastern point of Cuba, comes into view on the starboard bow, the dim form of the mountains of Hayti are visible on the opposite horizon. A subterranean connection is believed to exist between the mountain ranges of the two islands. We are now running through the Windward Pa.s.sage, as it is called; by which one branch of the Gulf Stream finds its way northward.

The Gulf Stream! Who can explain satisfactorily its ceaseless current?

What keeps its tepid waters, in a course of thousands of miles, from mingling with the rest of the sea? And finally whence does it come?

Maury, the great nautical authority, says the Gulf of Mexico is its fountain, and its mouth is the Arctic Sea. The maps make the eastern sh.o.r.e of Cuba terminate as sharp as a needle's point, but it proves to be very blunt in reality, where it forms one side of the gateway to the Caribbean Sea, and where the irregular coast line runs due north and south for the distance of many leagues.

The nights are mostly clear, soft, and lovely in this region. As we double Cape Maysi, and the ship is headed westward, the Southern Cross and the North Star blaze in the opposite horizons at the same time, the constellation on our port side (left-hand), and the North Star on the starboard side. Each day at noon the captain and his officers determine the exact position of the ship by "taking the sun," as it is termed.

When the sun reaches the meridian, that is, the point directly overhead, the exact moment is indicated by the nautical instrument known as a quadrant, adjusted to the eye of the observer. The figures marked on the quadrant give the lat.i.tude of the ship at the moment of meridian. The ship's time is then made to correspond,--that is to say, it must indicate twelve o'clock noon,--after which it is compared with an exact timepiece called a chronometer, which keeps Greenwich (English) time, and the difference enables the observer to determine the longitude. As fifteen miles are allowed to the minute, there will be nine hundred miles to the hour. Thus, by means of the chronometer and the quadrant, the sailing-master is enabled to designate his exact situation upon the ocean chart.
