We wasted no time in strategy or stealth, but opened her wide as soon as we were in the clear, and directed her straight towards the west and Phundahl. Scarcely had we passed over the gardens of Mu Tel when we met with our first adventure.

We shot by a solitary figure floating in the air and almost simultaneously there shrilled forth the warning whistle of an air patrol. A shot whistled above us harmlessly and we were gone; but within a few seconds I saw the rays of a searchlight shining down from above and moving searchingly to and fro through the air.

"A patrol boat!" shouted Gor Hajus in my ear. Hovan Du growled savagely and shook the chain upon his collar. We raced on, trusting to the big gods and the little gods and all our ancestors that the relentless eye of light would not find us out; but it did. Within a few seconds it fell full upon our deck from above and in front of us and there it clung as the patrol boat dropped rapidly towards us while it maintained a high rate of speed upon a course otherwise identical with ours. Then, to our consternation, the ship opened fire on us with explosive bullets. These projectiles contain a high explosive that is detonated by light rays when the opaque covering of the projectile is broken by impact with the target. It is therefore not at all necessary to make a direct hit for a shot to be effective. If the projectile strikes the ground or the deck of a vessel or any solid substance near its target, it does considerably more damage when fired at a group of men than if it strikes but one of them, since it will then explode if its outer shell is broken and kill or wound several; while if it enters the body of an individual the light rays cannot reach it and it accomplishes no more than a non-explosive bullet. Moonlight is not powerful enough to detonate this explosive and so projectiles fired at night, unless touched by the powerful rays of searchlights, detonate at sunrise the following morning, making a battlefield a most unsafe place at that time even though the contending forces are no longer there. Similarly they make the removal of the unexploded projectiles from the bodies of the wounded a most ticklish operation which may well result in the instant death of both the patient and the surgeon.

Dar Tarus, at the controls, turned the nose of our flier upward directly towards the patrol boat and at the same time shouted to us to concentrate our fire upon her propellers. For myself, I could see little but the blinding eye of the searchlight, and at that I fired with the strange weapon to which I had received my first introduction but a few hours since when it was presented to me by Mu Tel. To me that all searching eye represented the greatest menace that confronted us, and could we blind it the patrol boat would have no great advantage over us. So I kept my rifle straight upon it my finger on the button that controlled the fire, and prayed for a hit.

Gor Hajus knelt at my side, his weapon spitting bullets at the patrol boat. Dar Tarus' hands were busy with the controls and Hovan Du squatted in the bow and growled.

Suddenly Dar Tarus voiced an exclamation of alarm. "The controls are hit!" he shouted. "We can't alter our course-the ship is useless." Almost the same instant the searchlight was extinguished-one of my bullets evidently having found it. We were quite close to the enemy now and heard their shout of anger.

Our own craft, out of control, was running swiftly towards the other. It seemed that if there was not a collision we would pass directly beneath the keel of the air patrol. I asked Dar Tarus if our ship was beyond repair.

"We could repair it if we had time," he replied, "but it would take hours and while we were thus delayed the whole air patrol force of Toonol would be upon us."

"Then we must have another ship," I said. Dar Tarus laughed. "You are right, Vad Varo," he replied, "but where shall we find it?"

I pointed to the patrol boat. "We shall not have to look far."

Dar Tarus shrugged his shoulders. "Why not!" he exclaimed. "It would be a glorious fight and a worthy death."

Gor Hajus slapped me on the shoulder. "To the death, my captain!" he cried.

Hovan Du shook his chain and roared.

The two ships were rapidly approaching one another. We had stopped firing now for fear that we might disable the craft we hoped to use for our escape; and for some reason the crew of the patrol ship had ceased firing at us-I never learned why. We were moving in a line that would bring us directly beneath the other ship. I determined to board her at all costs. I could see her keel boarding tackle slung beneath her, ready to be lowered to the deck of a quarry when once her grappling hooks had seized the prey. Doubtless they were already manning the latter, and as soon as we were beneath her the steel tentacles would reach down and seize us as her crew swarmed down the board tackle to our deck.

I called Hovan Du and he crept back to my side where I whispered my instructions in his ear. When I was done he nodded his head with a low growl. I cast off the harness hook that held me to the deck, and the ape and I moved to our bow after I had issued brief, whispered instructions to Gor Hajus and Dar Tarus. We were now almost directly beneath the enemy craft; I could see the grappling hooks being prepared for lowering. Our bow ran beneath the stern of the other ship and the moment was at hand for which I had been waiting. Now those upon the deck of the patrol boat could not see Hovan Du or me. The boarding tackle of the other ship swung fifteen feet above our heads; I whispered a word of command to the ape and simultaneously we crouched and sprang for the tackle. It may sound like a mad chance-failure meant almost certain death-but I felt that if two of us could reach the deck of the patrol boat while her crew was busy with the grappling gear it would be well worth the risk.

Gor Hajus had assured me that there would not be more than six men aboard the patrol ship; that one would be at the controls and the others manning the grappling hooks. It would be a most propitious time to gain a footing on the enemy's deck.

Hovan Du and I made our leaps and Fortune smiled upon us, though the huge ape but barely reached the tackle with one outstretched hand, while my Earthly muscles carried me easily to my goal. Together we made our way rapidly towards the bow of the patrol craft and without hesitation, and as previously arranged, he clambered quickly up the starboard side and I the port. If I were the more agile jumper Hovan Du far outclassed me in climbing, with the result that he reached the rail and was clambering over while my eyes were still below the level of the deck, which was, perhaps, a fortunate thing for me since, by chance, I had elected to gain the deck directly at a point where, unknown to me, one of the crew of the ship was engaged with the grappling hooks. Had his eyes not been attracted elsewhere by the shout of one of his fellows who was first to see Hovan Du's savage face rise above the gunwale, he could have dispatched me with a single blow before ever I could have set foot upon the deck The ape had also come up directly in front of a Toonolian warrior and this fellow had let out a yell of surprise and sought to draw his sword, but the ape, for all his great bulk, was too quick for him; and as my eyes topped the rail I saw the mighty anthropoid seize the unfortunate man by the harness, drag him to the side and hurl him to destruction far below. Instantly we were both over the rail and squarely on deck while the remaining members of the craft's crew, abandoning their stations, ran forward to overpower us. I think that the sight of the great, savage beast must have had a demoralizing effect upon them, for they hesitated, each seeming to be willing to accord his fellow the honour of first engaging us; but they did come on, though slowly. This hesitation I was delighted to see, for it accorded perfectly with the plan that I had worked out, which depended largely upon the success which might attend the efforts of Gor Hajus and Dar Tarus to reach the deck of the patrol when our craft had risen sufficiently close beneath the other to permit them to reach the boarding tackle, which we were utilizing with reverse English, as one might say.
