EMPEROR WILLIAM II. OF GERMANY.

Since William II. of Germany ascended the throne as German Emperor and King of Prussia, on June 15, 1888, the eyes of Europe have been fixed on him. He has always been rather an unknown quantity, and he is regarded by the powers as an enfant terrible. The press of the world delights in showing up his weak points, and the "war lord" undoubtedly has them, but, at the same time, he has qualities which are to be admired and which make him conspicuous among the rulers of Europe.

He is popular in Germany, and it is not surprising, for, in spite of being autocratic to the last degree, he is honest, courageous, ambitious, hard working, and, withal, a thorough German, being intensely patriotic. Indeed, if the people of the Fatherland had the right to vote for a sovereign, they would undoubtedly choose the present constitutional ruler, for, while the virtues we have named may seem commonplace, they are not so when embodied in an emperor. One thing which places William at a disadvantage is his excessive frankness, which is, in him, almost a fault, for if he couched his utterances in courtly or diplomatic phrases, they would pass unchallenged, instead of being cited to ridicule him. His mistakes have largely resulted from his impulsive nature coupled with chauvinism, which is, perhaps, justifiable, or, at least, excusable, in a ruler.

Since the time when William was a child he evidenced a strong desire to become acquainted with the details of the office to which his lofty birth entitled him. It is doubtful if any king since the time of Frederick the Great has studied the routine of the public offices and has made such practical inspections of industries of all kinds; indeed, there is hardly a man in Germany who has more general knowledge of the material development of the country.

In the army he has worked his way up like any other officer and has a firm grasp on all the multifarious details of the military establishment of the great country. He believes in militarism, or in force to use a more common expression, but in this he is right, for it has taken two hundred and fifty years to bring Prussia to the position she now holds, and what she has gained at the point of the sword must be retained in the same way. The immense sacrifices which the people make to support the army and navy are deemed necessary for self-preservation, and with France on one side and Russia on the other, there really seems to be ample excuse for it. To-day the German army is as ready as in 1870, when Von Moltke walked down the Unter den Linden, the day after hostilities were declared, looking in the shop windows.

No ruler, except possibly Peter the Great, ever gave so many ex cathedra opinions on so many different subjects in the same length of time, and of course it cannot be supposed that he has not made mistakes, but it shows that it is only by prodigious industry that he has been able to gather the materials on which these utterances are based. He is indeed the "first servant of the state," and long before his court or indeed many of the housemaids of Berlin are awake, he is up ind attending to affairs of all kinds.

He is a great traveler, and knows Europe from the North Cape to the Golden Horn; and while flying across country in his comfortable vestibuled train, he dispatches business and acquires an excellent idea of the country, and no traveler can speak more intelligently of the countries through which he has traveled, and this information is brought out with good effect in his excellent after-dinner speeches.

In speaking of the versatility of the Emperor, something should be said of him as a sportsman. He has given a splendid example to the Germans. He has tried to introduce baseball, football and polo, three American games. This may be traced to the time when Poultney Bigelow and J. A. Berrian were the Emperor's playmates. Fenimore Cooper was one of the favorite authors with the young scion of royalty. The Emperor is fond of hunting, yachting, tennis and other sports and is never so happy as when he stands on the bridge of the royal yacht Hohenzollern. He is a well known figure at Cowes and won the Queen's Cup in 1891.

William II. was born January 27, 1859, in Berlin, and until he was fourteen years old his education was intrusted to Dr. Hintzpeter, assisted by Major Von Gottberg, who was military instructor. At this time his corps of teachers was increased by the addition of Prediger Persius, who prepared him for his confirmation, which took place September 1, 1874, at Potsdam. As William was to lead an active life, it was thought best to send him to the gymnasium at Cassel.

Orders were given that he and his younger brother Henry, who accompanied him, should receive the same treatment as the other pupils, and this order was strictly obeyed. He graduated from this school January 24, 1877, just before his eighteenth birthday. After this his military career began with his entrance as an officer into the first Garde-regiment at Potsdam, that he might become thoroughly acquainted with practical service. The young prince was assigned to the company which his father had once commanded. After serving here for a short time he went to the university at Bonn, and from there he went back to the army again. Emperor William ascended the throne in June, 1888, upon the death of his father Frederick III.

In 1880 he was betrothed to Augusta Victoria, Princess of Schleswig-Holstein, and on February 9, 1881, they were married. The Empress is about a year younger than the Emperor, and makes an excellent mother to her four little sons, to whom she is devoted. Their oldest child, little Prince William, the present Crown Prince, was born at Potsdam, May 6, 1882. His father's devotion to the army will doubtless prompt him to make a soldier of his son at an early age; in fact, he wore the uniform of a fusilier of the Guard before he was six years old.

The imperial family consists of seven children. The eldest, the Crown Prince of Germany and Prussia, is Prince Friedrich-Wilhelm-Victor-August-Ernst, born May 6, 1882. The second child is Prince Wilhelm-Eitel-Friedrich-Christian-Karl, born July 7, 1883. The third is Prince Adalbert-Ferdinand-Berenger-Victor, born July 14, 1884. Prince August-Wilhelm-Heinrich-Victor was born January 29. 1887. The fifth child, Prince Oscar-Karl-Gustav-Adolf, was born July 27, 1888. The sixth child is Prince Joachim-Francois-Humbert. He was born December 17, 1890. The youngest is a girl, Princess Victoria-Louise-Adelaide-Mathilde-Charlotte. She was born September 13, 1892.

MY RECENT JOURNEY FROM THE NILE TO SUAKIM.

By Frederic Villiers, in The Journal of the Society of Arts.

THE ADVANCE TO KHARTOUM.

The recent campaign in the Soudan was a bloodless one to the correspondent with the expedition, or, rather, on the tail of the advance. Yet I think, in spite of this little drawback, there is enough in the vicissitudes of my colleagues and myself during the recent advance of the Egyptian troops up the Nile to warrant me addressing you this afternoon. Especially as toward the end of the campaign the Sirdar, or Commander-in-Chief of the Egyptian army, Sir Herbert Kitchener, became more sympathetic with our endeavors to get good copy for our journals, and allowed us to return home by the old trade route of the Eastern Soudan, over which no European had passed since the revolt of the Eastern tribes in 1883. Unfortunately, the period for campaigning in the Soudan is in the hottest months in the year, on the rising of the Nile at the end of July, when the cataracts begin to be practicable for navigation. At the same time, in spite of the heat, it is the healthiest period, for the water, in its brown, muddy, pea soup state, is wholesomer to drink, and the banks of the river, which, when exposed at low Nile, give off unhealthy exhalations, are protected from spreading fever germs by the flood. To show you how much the people of Egypt depend for their very existence on this extraordinary river, the average difference between high and low Nile, giving favorable results, is 26 feet. Twenty-eight feet would cause serious damage by inundation, and the Nile as low as 20 feet would create a famine. The flood of the river depends entirely on the equatorial rains which cause the Upper White Nile to rise in April and the Blue Nile early in June. The muddy Atbara, joining her two sisters about the same time, sends the flood down to Lower Egypt toward the end of August at the rate of 100 miles a day. The Blue Nile in the middle of September falls rapidly away, while the Atbara leaves the trio in October. The White Nile is then left by herself to recede slowly and steadily from a current of four knots an hour to a sluggish and, in many parts, an unwholesome stream. Flies and mosquitoes increase, and fever is rife.

I arrived in Cairo on a sweltering day in July, and found four colleagues, who had been waiting for a week the Sirdar's permission to proceed to the front, still waiting. Luckily, the day after my arrival a telegram came from headquarters, saying that "we might proceed as far as Assouan and their await further orders." This, anyhow, was a move in the right direction; so we at once started. It was rather a bustle for me to get things ready, for Sunday blocked the way and little could be done, even on that day, in Cairo. I procured a servant, a horse and two cases of stores, for the cry was "nothing to be had up country in the shape of food; hardly sufficient sustenance to keep the flies alive." My colleagues, who had the start of me, were able to procure many luxuries—a case of cloudy ammonia for their toilet, and one of chartreuse, komel and benedictine to make their after dinner coffee palatable, and some plum pudding, if Christmas should still find them on the warpath, were a few of the many items that made up the trousseau of these up-to-date war correspondents, though at least one of them had been wedded to the life for many years. Unfortunately I had no time to procure these luxuries, and I had to proceed ammonialess and puddingless to the seat of war. My comrades were quite right. Why not do yourself well if you can? One of them even went in for the luxury of having three shooting irons, two revolvers and a double-barrel slug pistol, so that when either of the weapons got hot while he was holding Baggara horsemen at bay, there was always one cooling, ready to hand. He also, which I believe is a phenomenal record with any campaigner, took with him thirteen pairs of riding breeches, a half dozen razors and an ice machine. Even our commander-in-chief, when campaigning, denies himself more than two shirts and never travels with ice machines. But the thirteen pairs impressed me considerably. Why thirteen, more than fifteen, or any other number? I came to the conclusion that my colleague must certainly be a member of that mystic body the "Thirteen Club," and as he had to bring in the odd number somewhere to keep the club fresh in his memory, he occasionally sat upon it.

I found, after all, there was some wisdom in his eccentricity, for, when riding the camel, mounted on the rough saddle of the country, I often wished that I had my friend's forethought, and I should have been glad to have supplemented mine with his odd number. No doubt my colleague's idea in having such a variety of nether garments was to use them respectively, on a similar principle to the revolvers, when he rode in hot haste with his vivid account of the latest battle to the telegraph office.

But, unfortunately, this recent campaign did not, after all, necessitate these elaborate preparations, for there were no dervishes for us to shoot at or descriptions of bloody battles to be telegraphed. At all events, the cloudy ammonia and the thirteen breeches, with the assistance of a silken sash—a different color for each day of the week—made the brightest and smartest looking little man in camp. However, when I reflect on this new style of war correspondent, who, I forgot to mention, also carried with him two tents, a couple of beds, sundry chairs and tables, a silver-mounted dressing case, two baths, and a gross of toothpicks, and I think of the severe simplicity of the old style of campaigning when a famous correspondent who is still on the warpath, and who always sees the fighting if there be any, on one arduous campaign took with him the modest outfit of a tooth brush and a cake of carbolic soap, I joyfully feel that with the younger generation our profession is keeping pace with the luxury of the times.
