Luckily, most of the Harn was foraging in the new world. Two more stingers ambushed him, but the tobacco juice got rid of them, and he had no serious trouble till he got close to the den. Two carriers came out and rushed him there. He shot them both and then killed the stinger that was pecking at his shins. He moved quickly now, he had an idea that in about a minute all hell would break loose. He swung the pack down on the uphill side of the den, wet the musette bag with a quick spray of gas, tossed it over his shoulder, jammed the free end of the hose into the den mouth and stabbed the can with his knife to vent it. As the gas poured into the den he lit one of his oil and gas soaked bombs and ran around in front, lighting one after another from the one in his hand and tossing them into the den. The musette bag caught fire and he snatched it from his shoulder and tossed it after the bombs. A whoof and a sheet of flame blew out. About fifty yards away there was a slender, popplelike tree. Ed had thought if he could make that, he would be reasonably secure while the Harn burned. He ran for it as hard as he could, beating at the flames that had spattered on him from the burning gas, but he never made it. Harn were erupting everywhere. A carrier suddenly came charging out of the brush to his left. While Ed dealt with that one, the Harn played its ace in the hole. The two special units it had been developing to deal with Ed were not quite done yet, but they were done enough to work for the few minutes the Harn needed them. Ed heard a coughing grunt behind him and spun around to see something new crawling out of the flame and smoke at the den entrance. This one was a roughly carrier shaped creature, but half again as large, built for killing. It had powerful fanged jaws and its eight feet were armed with knifelike, disemboweling claws. As it came at Ed in a lumbering rush, another came crawling out after it. Ed shot four times, as fast as he could work the action. The heavy slugs did the job, but not quite well enough. With its dying lunge the thing got to him and tossed him ten feet like a rag doll. He lit on his bad hand and felt the wrist bones go. As he struggled to get up, digging his elbow in and using one hand, he saw a stinger darting in at him. He had lost both the bug gun and his rifle when the fighting unit swiped him. He swiveled on his hips and kicked the stinger away. Then he saw the second fighting unit coming. He forgot about the stinger. It still might get to him, but, if it did, it would be too late to matter. He drew his knife, managed to get to one knee, and crouched there like an old gray rat, stubbly lips drawn back from worn teeth in a grin of pain and rage. This was one he wasn't going to win, he guessed.
