fifth-order

But quick as he was, Seaton's flying fingers kept up with him, and before each torpedo disappeared through the ether gate there was fastened upon it a fifth-order tracer ray that would never leave it until the force had been disconnected at the gigantic control board of the Norlaminian projector. One flying minute passed during which seventy torpedoes had been launched, before Seaton spoke.

"You know, of course, that there are real scientists among the Fenachrone; and you yourself have suggested that while they cannot penetrate the zone of force nor use fifth-order rays, yet they might know about them in theory, might even be able to know when they were being used detect them, in other words.

I'd thought of setting up three or four courses of five-ply screen on the board a detector screen on the outside of each course, next to it a repeller, then a full-coverage ether-ray screen, then a zone of force, and a full-coverage fifth-order ray-screen as a liner. Then, with them all set up on the board, but not out, throw out a wide detector.

We know that they had at least a detector of fifth-order rays...." "And if they did have an analytical detector," Seaton interrupted, "they'll probably slap a ray on us as soon as we stick our nose out of the Galaxy!" "They may and even though I do not believe that there is any probability of them actually doing it, it will be well to be armed against the possibility."
