"Stop!" came the order, but I didn't stop; I was pulling away from him rapidly, as my ship was much the faster.

He fired then, but the shot went wide. Jad-han was at the stern gun. "Shall I let him have it?" he asked.

"No," I replied; "he may be Gatholian. Turn the searchlight on him, Pan Dan Chee; let's see if we can see his insigne."

Pan Dan Chee had never been on a ship before, nor ever seen a searchlight. The little remnant of the almost extinct race of Orovars, of which he was one, that hides away in ancient Horz, has neither ships nor searchlights; so Llana of Gathol came to his rescue, and presently the bow of the pursuing flier was brightly illuminated.

"I can't make out the insigne," said Llana, "but that is no ship of Gathol."

Another shot went wide of us, and I told Jad-han that he might fire. He did and missed. The enemy fired again; and I felt the projectile strike us, but it didn't explode. He had our range, so I started to zig zag, and his next two shots missed us. Jad-Han's also missed, and then we were struck again.

"Take the controls," I said to Llana, and I went back to the gun. "Hold her just as she is, Llana," I called, as I took careful aim. I was firing an explosive shell detonated by impact. It struck her full in the bow entered the hull, and exploded. It tore open the whole front of the ship, which burst into flame and commenced to go down by the bow. At first she went slowly; and then she took the last long, swift dive— a flaming meteor that crashed into the salt marsh and was extinguished.

"That's that," said Llana of Gathol.

"I don't think it's all of that as far as we are concerned," I retorted; "we are losing altitude rapidly; one of his shots must have ripped open a buoyancy tank."

I took the controls and tried to keep her up; as, with throttle wide open, I sought to pass that ring of camp fires before we were finally forced down.

Chapter 2

That was a good little ship—staunch and swift, as are all the ships of The Black Pirates of Barsoom—and it carried us past the farthest camp fires before it finally settled to the ground just at dawn. We were close to a small forest of sorapus trees, and I thought it best to take shelter there until we could reconnoiter a bit.

"What luck"' exclaimed Llana, disgustedly, "and just when I was so sure that we were practically safe and sound in Gathol."

"What do we do now?" asked Pan Dan Chee.

"Our fate is in the hands of our ancestors," said Jad-han.
