When I returned from school for my vacation, after I had my first year of physical science, I sought out my uncle in his laboratory and asked him to explain the mystery of the little black island standing adamant in the golden sea of all the world.

"That spot," said my uncle, "would have been erased in two more years if a Leipzig professor had not discovered The Ray. Yet we do not know his name nor how he made his discovery."

"But just what is The Ray?" I asked.

"We do not know that either, nor how it is made. We only know that it destroys the oxygen carrying power of living blood. If it were an emanation from a substance like radium, they could have fired it in projectiles and so conquered the earth. If it were ether waves like electricity, we should have been able to have insulated against it, or they should have been able to project it farther and destroy our aircraft, but The Ray is not destructive beyond two thousand metres in the air and hardly that far in the earth."

"Then why do we not fly over and land an army and great guns and batter down the walls of Berlin and he done with it?"

"That, as you know if you studied your history, has been tried many times and always with disaster. The bomb-torn soil of that black land is speckled white with the bones of World armies who were sent on landing invasions before you or I was born. But it was only heroic folly, one gun popping out of a tunnel mouth can slay a thousand men. To pursue the gunners into their catacombs meant to be gassed; and sometimes our forces were left to land in peace and set up their batteries to fire against Berlin, but the Germans would place Ray generators in the ground beneath them and slay our forces in an hour, as the Angel of Jehovah withered the hosts of the Assyrians."

"But why," I persisted, "do we not tunnel under the Ray generators and dig our way to Berlin and blow it up?"

My uncle smiled indulgently. "And that has been tried too, but they can hear our borings with microphones and cut us off, just as we cut them off when they try to tunnel out and place new generators. It is too slow, too difficult, either way; the line has wavered a little with the years but to no practical avail; the war in our day has become merely a watching game, we to keep the Germans from coming out, they to keep us from penetrating within gunshot of Berlin; but to gain a mile of worthless territory either way means too great a human waste to be worth the price. Things must go on as they are till the Germans tire of their sunless imprisonment or till they exhaust some essential element in their soil. But wars such as you read of in your history, will never happen again. The Germans cannot fight the world in the air, nor in the sea, nor on the surface of the earth; and we cannot fight the Germans in the ground; so the war has become a fixed state of standing guard; the hope of victory, the fear of defeat have vanished; the romance of war is dead."
