I was touched by her loyalty, but I did not like to think of Tavia as a slave; yet however much I might loathe the idea the fact remained that she was one. "I give you your freedom, Tavia," I said.

She smiled. "I do not want it and now that it is decided that I am to remain with you" (she had done all the deciding), "I wish to learn all that I can about navigating the Jhama, for it may be that in that way I may help you."

Tavia's knowledge of aerial navigation made the task of instructing her simple indeed; in fact she had no trouble whatsoever in handling the craft.

Phao also manifested an interest and it was not long before she, too, took her turn at the controls, while Tavia insisted upon being inducted into all the mysteries of the disintegrating ray rifle.

Long before we saw the towers of Tul Axtar's capital, we sighted a one-man scout flier painted the ghastly blue of Jahar, and then far to the right and to the left we saw others. They were circling slowly at a great altitude. I judged that they were scouts watching for the coming of an expected enemy fleet. We passed below them and a little later encountered the second line of enemy ships. These were all scout cruisers, carrying from ten to fifteen men. Approaching one of them quite closely I saw that it carried four disintegrating ray rifles, two mounted forward and two aft. As far as I could see in either direction these ships were visible, and if, as I presumed, they formed a circle entirely about Jahar, they must have been numerous indeed.

Passing on beyond them we presently encountered the third line of Jaharian ships. Here were stationed huge battleships, carrying crews of a thousand men and more and fairly bristling with big guns.

While none of these ships was as large as the major ships of Helium, they constituted a most formidable force and it was obvious that they had been built in great numbers.

What I had already seen impressed me with the fact that Tul Axtar was entertaining no idle dream in his contemplated subjection of all Barsoom. With but a fraction of the ships I had already seen I would guarantee to lay waste all of Barsoom, provided my ships were armed with disintegrating ray rifles, and I felt sure that I had seen but a pitiful fraction of Tul Axtar's vast armament.

The sight of all these ships filled me with the direst forebodings of calamity. If the fleet of Helium had not already arrived and been destroyed, it certainly must be destroyed when it did arrive. No power on earth could save it. The best that I could hope, had the fleet already arrived, was that an encounter with the disintegrating ray rifles of the first line might have proved sufficient warning to turn the balance of the fleet back.

Far behind the line of battleships I could see the towers of Jahar rising in the distance, and as we reached the vicinity of the city I descried a fleet of the largest ships I have ever seen, resting upon the ground just outside the city wall. These ships, which completely encircled the city wall that was visible to us, must have been capable of accommodating at least ten thousand men each, and from their construction and their light armaments, I assumed them to be transports. These, doubtless, were to carry the hordes of hungry Jaharian warriors upon the campaign of loot and pillage that it was planned should destroy a world.
