"This new rifle," he continued after a moment's silence, "would render all the other armies and navies of Barsoom impotent before us. It projects an invisible ray, the vibrations of which effect such a change in the constitution of metals as to cause them to disintegrate. I am not a scientist; I do not fully understand the exact explanation of the phenomenon, but from what I was able to gather while the new weapon was being discussed in Jahar I am under the impression that these rays change the polarity of the protons in metallic substances, releasing the whole mass as free electrons. I have also heard the theory expounded that Phor Tak, in his investigation, discovered that the fundamental principle underlying time, matter and space are identical, and that what the rays projected from his rifle really accomplish is to translate any mass of metal upon which it is directed into the most elementary constituents of space. "But be that as it may, Tul Axtar had the manpower and the weapon, yet still he hesitated. He was afraid and he sought for some excuse further to delay the war of conquest and loot which his millions of subjects now demanded, and to this end he hit upon the plan of insisting upon some medium of defense against this new rifle, basing his demands upon the possibility that some other power might also have discovered a similar weapon or would eventually, by the use of spies or informers, learn the secret from Jahar. Probably greatly to his surprise and unquestionably to his embarrassment, a man who had been an assistant in Phor Tak's laboratory presently developed a substance which dissipated the rays of the new weapon, rendering them harmless. With this substance, which is of a bluish color, the metal portions of the ships, weapons and harness of Jahar are now painted. "But yet again Tul Axtar postponed his war, insisting upon the production of an enormous quantity of the new rifles and a mighty fleet of warships upon which to mount them. Then, he says, he will sail forth and conquer all Barsoom."
