After the exhibition was finished, and amid the fresh outburst of enthusiasm that followed, it was suggested that a proper way to wind up the Congress and give suitable expression to the festive mood which now possessed mankind would be to have a grand ball. This suggestion met with immediate and universal approval. But for so gigantic an affair it was, of course, necessary to make special preparations. A convenient place was selected on the Virginia side of the Potomac; a space of ten acres was carefully levelled and covered with a polished floor, rows of columns one hundred feet apart were run across it in every direction, and these were decorated with electric lights, displaying every color of the spectrum. Above this immense space, rising in the center to a height of more than a thousand feet, was anchored a vast number of balloons, all aglow with lights, and forming a tremendous dome, in which brilliant lamps were arranged in such a manner as to exhibit, in an endless succession of combinations, all the national colors, ensigns and insignia of the various countries represented at the Congress. Blazing eagles, lions, unicorns, dragons and other imaginary creatures that the different nations had chosen for their symbols appeared to hover high above the dancers, shedding a brilliant light upon the scene. Circles of magnificent thrones were placed upon the floor in convenient locations for seeing. A thousand bands of music played, and tens of thousands of couples, gayly dressed and flashing with gems, whirled together upon the polished floor. The Queen of England led the dance, on the arm of the President of the United States. The Prince of Wales led forth the fair daughter of the President, universally admired as the most beautiful woman on the great ballroom floor. The Emperor William, in his military dress, danced with the beauteous Princess Masaco, the daughter of the Mikado, who wore for the occasion the ancient costume of the women of her country, sparkling with jewels, and glowing with quaint combinations of color like a gorgeous butterfly. The Chinese Emperor, with his pigtail flying high as he spun, danced with the Empress of Russia. The King of Siam essayed a waltz with the Queen Ranavalona of Madagascar, while the Sultan of Turkey basked in the smiles of a Chicago heiress to a hundred millions. The Czar chose for his partner a dark-eyed beauty from Peru, but King Malietoa, of Samoa, was suspicious of civilized charmers and, avoiding all of their allurements, expressed his joy and gave vent to his enthusiasm in a _pas seul_. In this he was quickly joined by a band of Sioux Indian chiefs, whose whoops and yells so startled the leader of a German band on their part of the floor that he dropped his baton, and followed by the musicians, took to his heels. This incident amused the good-natured Emperor of China more than anything else that had occurred.
