Eagerly I pressed forward against the glass wall of the observatory, scarce daring to credit the testimony of my own eyes. But at last I could doubt no longer, and with a shout of joy that rose strangely in the midst of the cursing and groaning of the battling men at the entrance to the chamber, I called to Tardos Mors.

As he joined me I pointed down into the streets of Kadabra and to the advancing columns beyond, above which floated bravely in the arctic air the flags and banners of Helium.

An instant later every red man in the lofty chamber had seen the inspiring sight, and such a shout of thanksgiving arose as I warrant never before echoed through that age-old pile of stone.

But still we must fight on, for though our troops had entered Kadabra, the city was yet far from capitulation, nor had the palace been even assaulted. Turn and turn about we held the top of the runway while the others feasted their eyes upon the sight of our valiant countrymen battling far beneath us.

Now they have rushed the palace gate! Great battering-rams are dashed against its formidable surface. Now they are repulsed by a deadly shower of javelins from the wall’s top!

Once again they charge, but a sortie by a large force of Okarians from an intersecting avenue crumples the head of the column, and the men of Helium go down, fighting, beneath an overwhelming force.

The palace gate flies open and a force of the jeddak’s own guard, picked men from the flower of the Okarian army, sallies forth to shatter the broken regiments. For a moment it looks as though nothing could avert defeat, and then I see a noble figure upon a mighty thoat—not the tiny thoat of the red man, but one of his huge cousins of the dead sea bottoms.

The warrior hews his way to the front, and behind him rally the disorganized soldiers of Helium. As he raises his head aloft to fling a challenge at the men upon the palace walls I see his face, and my heart swells in pride and happiness as the red warriors leap to the side of their leader and win back the ground that they had but just lost—the face of him upon the mighty thoat is the face of my son—Carthoris of Helium.

At his side fights a huge Martian war-hound, nor did I need a second look to know that it was Woola—my faithful Woola who had thus well performed his arduous task and brought the succoring legions in the nick of time.

“In the nick of time?”
