After the first rush, it was obvious to the Harn that the cabin was going to be a tough nut to crack. On the other hand, there was no rush about it either. Necessarily, it had let its hunting go the past several days while it concentrated on Ed. It was pretty hungry, and it was in rich pickings now--Ed had always kept from disturbing game close to the cabin, partly because he liked to see it around, and partly because he had an idea that some day he might be in a fix where he couldn't travel very well, and would want meat close to hand. The Harn felt no such compunctions. The stinging units spread through the woods, and shortly a steady procession of loaded carriers began to stream back through the hole. Ed picked off the first few, but then the Harn found it could route them up the river trail in such a way that he got only a glimpse as they flashed through the hole. After that he did not hit very many. Ed stopped shooting. He was getting short on ammunition for the .30 now, too. He counted up. There were eighteen rounds for the .450, half a box of 220 grain soft point for the .30 plus about the same amount of military stuff, and a handful of shotgun shells. Of course, there was still the .30 Luger with a couple of boxes, and the .22; but they were not much account for this kind of work. He looked at the cabin door. It was stout, built of hewed three-inch slabs, but it wouldn't last forever against the kind of beating the gate had got. Even if it did, he was going to run out of water eventually. Ed thought about that for a while, sitting at the table staring at the little pile of cartridges. He was going to be run out of here sooner or later, he might as well pick his own time, and now seemed about as good as any, while the Harn was busy exploring and hunting. He sighed and got up to rummage around the cabin. The snakeproof pants had done real good, but he did not trust them entirely. There was some sheet iron laid over the ceiling joists, which he had brought up to make new stoves for his line camps. He got this down and cut it into small pieces. Around the edges he drilled a number of small holes. Then he got out his mending gear and began sewing the plates, in an overlapping pattern, to the legs of the snakeproof pants and to an old pair of moccasins. When he finished, he was pretty well armored as far as his crotch. It was an awkward outfit to move around in, but as long as he was able to stay on his feet, he figured he would be reasonably secure from the stingers. As for the bigger ones, he would just have to depend on seeing them first, and the .450. Next, he needed some gasoline. The fuel cache was under a big spruce, about twenty yards from the door. He made the round of his loopholes. There were no Harn in sight, they were apparently ignoring him for now. He slipped out the door, closing it securely behind him, and started for the cache.
