"They take one trick!" he blazed, his eyes almost emitting sparks, and leaped for the generators. He had forgotten the efforts of the zone of force, however, and only sprawled grotesquely in the air until he floated within reach of a line.
"Hold everything, Dick!" Crane snapped, as Seaton bent over one of the bars. "What are you going to do?"
"I'm going to put as heavy bars in these ray-generators as they'll stand and go out and get that bird. We can't lick him with Osnomian rays or with our explosive copper, but I can carve that sausage into slices with a zone of force, and I'm going to do it."
"Steady, old man—take it easy. I see your point, but remember that you must release the zone of force before you can use it as a weapon. Furthermore, you must discover his exact location, and must get close enough to him to use the zone as a weapon, all without its protection. Can those ray-screens be made sufficiently powerful to withstand the beam they employed last, even for a second?"
"Hm ... m ... m. Never thought of that, Mart," Seaton replied, the fire dying out of his eyes. "Wonder how long the battle lasted?"
"Eight and two-tenths seconds, from first to last, but they had had that heavy ray in action only a fraction of one second when you cut in the zone of force. Either they underestimated our strength at first, or else it required about eight seconds to tune in their heavy generators—probably the former."
"But we've got to do something, man! We can't just sit here and twiddle our thumbs!"
"Why, and why not? That course seems eminently wise and proper. In fact, at the present time, thumb-twiddling is distinctly indicated."
"Oh, you're full of little red ants! We can't do a thing with that zone on—and you say just sit here. Suppose they know all about that zone of force? Suppose they can crack it? Suppose they ram us?"
"I shall take up your objections in order," Crane had lighted a cigarette and was smoking meditatively. "First, they may or may not know about it. At present, that point is immaterial. Second, whether or not they know about it, it is almost a certainty that they cannot crack it. It had been up for more than three minutes, and they have undoubtedly concentrated everything possible upon us during that time. It is still standing. I really expected it to go down in the first few seconds, but now that it has held this long it will, in all probability, continue to hold indefinitely. Third, they most certainly will not ram us, for several reasons. They probably have encountered few, if any, foreign vessels able to stand against them for a minute, and will act accordingly. Then, too, it is probably safe to assume that their vessel is damaged, to some slight extent at least; for I do not believe that any possible armament could withstand the forces you directed against them and escape entirely unscathed. Finally, if they did ram us, what would happen? Would we feel the shock? That barrier in the ether seems impervious, and if so, it could not transmit a blow. I do not see exactly how it would affect the ship dealing the blow. You are the one who works out the new problems in unexplored mathematics—some time you must take a few months off and work it out."
