"You're forgetting again, son. Remember that the hot, dense material is entirely enclosed in an envelope impervious to all vibrations longer than those of the fifth order. You could put your hand upon it now, without receiving any sensation either of heat, or of cold."
"Yeah, that's right, too. I noticed that I could take a faidon right out of an electric arc and it wouldn't even be warm. I couldn't explain why it was, but I see now. So that stuff inside that lens will always stay as hot as it is right now! Zowie! Here's hoping she never explodes! Well, there's the bell—for once in my life, I'm all ready to quit when the whistle blows," and arm in arm the young Terrestrial chemist and the aged Norlaminian physicist strolled out to their waiting airboat.
CHAPTER XII
Flying Visits—Via Projection
"Well, what to do?" asked Seaton as he and Rovol entered the laboratory, "Tear down this fourth-order projector and tackle the big job? I see the lens is here, on schedule, so we can hop right into it."
"We shall have further use for this mechanism. We shall need at least one more lens of this dense material, and other scientists also may have need of one or two. Then, too, the new projector must be so large that it cannot be erected in this room."
As he spoke, Rovol seated himself at his control-desk and ran his fingers lightly over the keys. The entire wall of the laboratory disappeared, hundreds of beams of force darted here and there, seizing and working raw materials, and in the portal there grew up, to Seaton's amazement, a keyboard and panel installation such as the Earth-man, in his wildest moments, had never imagined. Bank upon bank of typewriter-like keys; row upon row of keys, pedals, and stops resembling somewhat those of the console of a gigantic pipe-organ; panel upon panel of meters, switches, and dials—all arranged about two deeply-cushioned chairs and within reach of their occupants.
"Whew! That looks like the combined mince-pie nightmares of a whole flock of linotype operators, pipe-organists, and hard-boiled radio hams!" exclaimed Seaton when the installation was complete. "Now that you've got it, what are you going to do with it?"
"There is not a control system in Norlamin adequate for the task we face, since the problem of the projection of rays of the fifth order has heretofore been of only academic interest. Therefore it becomes necessary to construct such a control. This mechanism will, I am confident, have a sufficiently wide range of application to perform any operation we shall require of it."
