ome super-gun, said science with conviction; a great bore in the planet itself, perhaps. But it was fixed, and the planet itself aimed with an accuracy that was deadly; aimed once as each revolution brought its gun on the target. Herein, said science, lay a basis for hope.

If, in that distant world, there was only one such bore, it must be altering its aim as the planet approached; the gun must cease to bear upon the earth. And the changing sweep of the missiles' flight confirmed their belief.

Each meteor-shell that came rushing into Earth's embrace burned brilliantly as it tore into the air. And each flaming arc was increasingly bent, until—twenty hours and nineteen minutes had passed—twenty minutes—thirty—another hour ... and the peoples of Earth dropped humbly to their knees in thankful prayer, or raised vengeful eyes and clenched fists toward the heavens while their quivering lips uttered blasphemous curses. The menace, for the time, had passed; the great gun of Venus no longer was aiming toward the earth.

"No more ships," was the belief; "not this time." And the world turned to an accounting of its losses, and to wonder—wonder—what the planet's return would bring. A year and one half was theirs; one year and a half in which to live in safety, in which to plan and build.

"Another attack," it concluded, "is not a probability—it is a certainty. They are destroying us for some reason known only to themselves. Who can doubt that when the planet returns there will be a further bombardment; an invasion by armed forces in giant ships; bombs dropped from them miles high in the air. This is what we must look forward to—death and destruction dealt out by a force we are unable to meet.

"Our munitions factories may build larger guns, but can they reach the heights at which these monster ships of space will lie, with any faint probability of inflicting damage? It is doubtful.

"Our aircraft is less than useless; its very name condemns it as inept. Craft of the air!—and we have to war against space ships which can rise beyond the thin envelope of gas that encircles the earth.
