Quite plainly, it did not like the lights. It blinked several ‘times as the main spotlight burned into its eyes, and Lackland could see the great pupils contract; then, with a wailing hiss that was picked up by the roof speaker and clearly transmitted to the man inside, it lumbered a few feet forward and struck.
Lackland had not realized that he was so close — or, more correctly, that the thing could reach so far. The neck, even longer than he had at first estimated, snapped to full length, carrying the massive head forward and a trifle to one side. As it reached full travel, the head tipped a trifle and came slashing sideways. One of the great tusks clanged resoundingly against the tank’s armor, and the main light went out in the same instant. Another, shriller hiss suggested to Lackland that the current feeding the light had grounded into the armor through some portion of the monster’s head; but he was not taking time out to analyze the possibility. He backed away hastily, cutting the cabin lights as he did so. He did not want one of those tusks striking a cabin port with the force it had just expended on the upper armor. Now only the running lights, mounted low in the front of the vehicle and set well into the armor, were illuminating the scene. The animal, encouraged by Lackland’s retreat, lurched forward again and struck at one of these. The Earthman did not dare extinguish it, since it would have left him effectively blind; but he sent a frantic call on the radio.
„Barl! Are you doing anything about your nets? If you’re not about ready for action, I’m going to have to use the gun on this thing, meat or no meat. You’ll have to stay away if I do; he’s so close that high explosive would endanger the tank, and I’ll have to use thermite.”
„The nets are not ready, but if you’ll lead him back a few more yards hell be downwind of the ship, and we can take care of him another way.”
„All right.” Lackland did not know what the other way could be, and was more than a little doubtful of its effectiveness, whatever it was; but as long as retreat would suit the captain he was prepared to co-operate. It did not for an instant occur to him that Barlennan’s weapon might endanger the tank; and, in all fairness, it probably did not occur to Barlennan either. The Earthman, by dint of repeated and hasty withdrawals, kept the tusks from his plating most of the time; the monster did not seem to have the intelligence to anticipate motion on his part. Two or three minutes of this dodging satisfied Barlennan.
He, too, had been busy in those minutes. On the leeward rafts, toward the dueling monster and machine, were four devices closely resembling bellows, with hoppers mounted above their nozzles. Two sailors were now at each bellows, and at their captain’s signal began pumping for all they were worth. At the same time a third operator manipulated — the hopper and sent a stream of fine dust flowing into the current from the nozzle. This was picked up by the wind and carried toward the combatants. The darkness made it difficult to estimate its progress; but Barlennan was a good judge of wind, and after a few moments of pumping suddenly snapped out another order.
The hopper crews promptly did something at the nozzle of the bellows each was tending; and as they did so, a roaring sheet of flame spread downwind from the Bree to envelop both of the fighters. The ship’s crew were already sheltered behind their tarpaulins, even the „gunners” being protected by flaps of fabric that formed part of their weapons; but the vegetation that sprouted through the snow was neither tall nor dense enough to shelter the fighters. Lackland, using words that he had never taught Barlennan, hurled the tank backward out of the flame cloud with a prayer for the quartz in his portholes. His adversary, though evidently as anxious to dodge, seemed to lack the necessary control. It lurched first one way, then the other, seeking escape. The flame died out in seconds, leaving a cloud of dense white smoke which gleamed in the tank’s running lights; but either the brief fire had been sufficient or the smoke was equally deadly, for the monster’s disorganization grew steadily worse. Its aimless steps grew shorter and feebler as the legs gradually lost the power to support its vast bulk, and presently it stumbled and rolled on-one side. The legs kicked frantically for a time, while the long neck alternately retracted and stretched to full length, lashing the fanged head frantically through the air and against the ground. By sunrise the only remaining motion, was an occasional — twitch of head or leg; within a minute or two thereafter all activity of the giant creature ceased. The crew of the Bree had already swarmed overboard and across the dark patch where the snow had boiled from the ground, bent on acquiring meat. The deadly white cloud was farther downwind now, and gradually settling. Lackland was surprised to note traces of black dust on the snow where the cloud had passed.
„Barl, what on Earth — or rather, on Mesklin — was the stuff you used for that fire cloud? And didn’t it occur to you that it might crack the windows in this tank?” The captain, who had remained on the ship and was near one of his radios, answered promptly.
„I’m sorry, Charles; I didn’t know what your windows are made of, and never thought of our flame cloud as a danger to your great machine. I will be more careful next time. The fuel is simply a dust which we obtain from certain plants-it is found as fairly large crystals, which we have to pulverize very carefully and away from all light.” Lackland nodded slowly, digesting this information. His chemical knowledge was slight, but it was sufficient to make a good guess at the fuel’s nature. Ignited by, light — burned in hydrogen with a white cloud — black specks on the snow — it could, as far as he knew, be only one thing. Chlorine is solid at Mesklin’s temperature; it combines violently with hydrogen, and hydrogen chloride is white when in fine powder form; methane snow boiled from the ground would also give up its hydrogen to the voracious element and leave carbon. Interesting plant life this world sported! He must make another report to Toorey — or perhaps he had better save this tidbit in case he annoyed Rosten again.
„I am very sorry I endangered your tank.” Barlennan still seemed to feel apologetic. „Perhaps we had better let you deal with such creatures with your gun; or perhaps you could teach us to use it. Is it, like the radios, especially built to work on Mesklin?” The captain wondered if he had gone too far with this suggestion, but decided it had been worth it. He could neither see nor interpret Lackland’s answering smile.
„No, the gun was not remade or changed for this world, Barl. It works fairly well here, but I’m afraid it would be pretty useless in your country.” He picked up a slide rule, and added one more sentence after employing it for a moment. „The farthest this thing could possibly shoot at your pole would be just about one hundred fifty feet.”
Barlennan, disappointed, said nothing further. Several days were spent in butchering the dead monster. Lackland salvaged the skull as a further protection from Rosten’s ire, and the cavalcade resumed its journey.
Mile after mile, day after day, the tank and its tow inched onward. Still they sighted occasional cities of the rock-rollers; two or three times they picked up food for Lackland which had been left in their path by the rocket; quite frequently they encountered large animals, some like the one Barlennan’s fire had slain, others very different in size and build. Twice specimens of giant herbivores were netted and killed by the crew to furnish meat, much to Lackland’s admiration. The discrepancy in size was far greater than that existing between Earthly elephants and the African pygmies who sometimes hunted them.
The country grew hillier as they progressed, and with the rising ground the river, Which they had followed intermittently for hundreds of miles, shrank and split into numerous smaller streams. Two of ‘these tributaries had been rather difficult to cross, requiring that the Bree be unlashed from the sled and floated across at the end of a towrope while tank and sled drove below the surface on the river bed. Now, however, the streams had become so narrow that the sled actually bridged them and no such delays occurred.
