“That will be in early summer,” George Ord said, his black eyes thoughtful. “Whoever goes will have to time their return for either just before the prowlers and unicorns come back from the north or wait until they’ve all migrated down off the plateau.”
It was something Humbolt had been thinking about and wishing they could remedy. Men could elude unicorn attacks wherever there were trees large enough to offer safety and even prowler attacks could be warded off wherever there were trees for refuge; spears holding back the prowlers who would climb the trees while arrows picked off the ones on the ground. But there were no trees on the plateau, and to be caught by a band of prowlers or unicorns there was certain death for any small party of two or three. For that reason no small parties had ever gone up on the plateau except when the unicorns and prowlers were gone or nearly so. It was an inconvenience and it would continue for as long as their weapons were the slow-to-reload bows.
“You’re supposed to be our combination inventor-craftsman,” he said to George. “No one else can compare with you in that respect. Besides, you’re not exactly enthusiastic about such hard work as mountain climbing. So from now on you’ll do the kind of work you’re best fitted for. Your first job is to make us a better bow. Make it like a crossbow, with a sliding action to draw and cock the string and with a magazine of arrows mounted on top of it.”
George studied the idea thoughtfully. “The general principle is simple,” he said. “I’ll see what I can do.”
“How many of us will go over the Craig Mountains, Bill?” Dan Barber asked.
“You and I,” Humbolt answered. “A three-man party under Bob Craig will go into the Western Hills and another party under Johnny Stevens will go into the Eastern Hills.”
He looked toward the adjoining cave where the guns had been stored for so long, coated with unicorn tallow to protect them from rust.
“We could make gun powder if we could find a deposit of saltpeter. We already know where there’s a little sulphur. The guns would have to be converted to flintlocks, though, since we don’t have what we need for cartridge priming material. Worse, we’d have to use ceramic bullets. They would be inefficient—too light, and destructive to the bores. But we would need powder for mining if we ever found any iron. And, if we can’t have metal bullets to shoot the Gerns, we can have bombs to blast them with.”
“Suppose,” Johnny Stevens said, “that we never do find the metals to make a ship. How will we ever leave Ragnarok if that happens?”
“There’s another way—a possible way—of leaving here without a ship of our own. If there are no metals we’ll have to try it.”
“Why wait?” Bob Craig demanded. “Why not try it now?”
“Because the odds would be about ten thousand to one in favor of the Gerns. But we’ll try it if everything else fails.”
George made, altered, and rejected four different types of crossbows before he perfected a reloading bow that met his critical approval. He brought it to where Humbolt stood outside the caves early one spring day when the grass was sending up the first green shoots on the southern hillsides and the long winter was finally dying.
“Here it is,” he said, handing Humbolt the bow. “Try it.”
He took it, noting the fine balance of it. Projecting down from the center of the bow, at right angles to it, was a stock shaped to fit the grip of the left hand. Under the crossbar was a sliding stock for the right hand, shaped like the butt of a pistol and fitted with a trigger. Mounted slightly above and to one side of the crossbar was a magazine containing ten short arrows.
The pistol grip was in position near the forestock. He pulled it back the length of the crossbar and it brought the string with it, stretching it taut. There was a click as the trigger mechanism locked the bowstring in place and at the same time a concealed spring arrangement shoved an arrow into place against the string.
He took quick aim at a distant tree and pressed the trigger. There was a twang as the arrow was ejected. He jerked the sliding pistol grip forward and back to reload, pressing the trigger an instant later. Another arrow went its way.
By the time he had fired the tenth arrow in the magazine he was shooting at the rate of one arrow per second. On the trunk of the distant tree, like a bristle of stiff whiskers, the ten arrows were driven deep into the wood in an area no larger than the chest of a prowler or head of a unicorn.
“This is better than I hoped for,” he said to George. “One man with one of these would equal six men with ordinary bows.”
“I’m going to add another feature,” George said. “Bundles of arrows, ten to the bundle in special holders, to carry in the quivers. To reload the magazine you’d just slap down a new bundle of arrows, in no more time than it would take to put one arrow in an ordinary bow. I figured that with practice a man should be able to get off forty arrows in not much more than twenty seconds.”
George took the bow and went back in the cave to add his new feature. Humbolt stared after him, thinking, If he can make something like that out of wood and unicorn gut, what would he be able to give
