The room, practically destitute of ordinary furniture, was fitted up as a chemical and physical laboratory, and the man was Doctor Emil Fargeau, the most distinguished scientific investigator that the lost province of Alsace had produced—a tall, spare man of about sixty, with sloping, stooping shoulders and forward-thrown head, thinly covered with straggling iron-grey hair. It was plain that he was in the habit of shaving clean, but just now there was a short white stubble both on his upper lip and on the lean wrinkled cheeks which showed the nervous workings of the muscles so plainly. In fact, his whole appearance was that of a man too completely absorbed by an over-mastering idea to pay any attention to the small details of life.

And such was the exact truth—for these few mid-night minutes which were being ticked off by an ancient wooden clock in the corner were the most anxious of his life. In fact, a few more of them would decide whether the Great Experiment, for which he had sacrificed everything, even to his home and his great professional position, was to be a success or a failure.

On the long, bare, pine table, beside which he was pacing up and down, stood a strange fabric about three feet high. It was round, and about the size of a four-gallon ale jar. It was covered completely by a closed glass cylinder, and rested on four strong glass supports. From the floor on either side of the table a number of twisted, silk-covered wires rose from two sets of storage batteries. Within the four supports was a wooden dish, and on this lay a piece of bright steel some four inches square and about an inch thick, just under a circle of needles which hung down in a circle from the bottom of the machine.

A very faint humming sound filled the room, and made a somewhat uncanny accompaniment to the leisurely tick of the clock and the irregular shuffling of the doctor's slippered feet.

Every now and then he stopped, and put his ear near to the machine, and then looked at the piece of steel with a gleam of longing anticipation in his keen, deep-set, grey eyes. Then he began his walk again, and his lips went on working, as though he were holding an inaudible conversation with himself. At last there came a faint whirr from the clock, a little window opened, and a wooden bird bobbed out and said "Cuckoo" once. The doctor stopped instantly, took out his watch and compared it with the clock.

"Now, let us see!" he said, quietly, in his somewhat guttural Alsatian French, for in this supreme moment of his life he had gone back to the patois of his boyhood, which he had spoken in the days before the Teuton's iron hand had snatched his well-loved native land from France and begun to rule it according to the pitiless doctrine of Blood and Iron.

He pulled the platter out from under the machine, picked up a little wooden mallet from the table, and, with a trembling hand, struck the steel plate in the centre. It splintered instantly to fragments, as though it had only been a thin sheet of glass. The doctor dropped the mallet, lifted his hand to the window that looked out over the river towards the citadel, and said:

"It is done! And so, Germany, stealer of our land and oppressor of my people, will I break the great fabric of your power with one touch of this weak old hand of mine!"

Then he threw open one of the old-fashioned dormer windows that looked out over the northern part of the city towards France, and began to speak again in a low, intense tone which rose and fell slightly as his deep breaths came and went.

"But France, my beautiful mother France, thou shalt know soon that I have done more than given thee the power to turn on thy conqueror and crush him. I can make thee queen and mistress of the world, and I will do it. The other nations shall live and prosper only at thy bidding, and they shall pay thee tribute for the privilege of being something more than the savages from which they came.
