historic day, June 10th, 1967, that Earth received her first message from Mars, since which the two planets have remained in constant friendly communication, carrying on a commerce of reciprocal enlightenment. In some branches of the arts and sciences the Martians, or Barsoomians, as they call themselves, were far in advance of us, while in others we had progressed more rapidly than they. Knowledge was thus freely exchanged to the advantage of both worlds. We learned of their history and customs and they of ours, though they had for ages already known much more of us than we of them. Martian news held always a prominent place in our daily papers from the first.
They helped us most, perhaps, in the fields of medicine and aeronautics, giving us in one, the marvelous healing lotions of Barsoom and in the other, knowledge of the Eighth Ray, which is more generally known on Earth as the Barsoomian Ray, which is now stored in the buoyancy tanks of every air craft and has made obsolete those ancient types of plane that depended upon momentum to keep them afloat.
That we ever were able to communicate intelligibly with them is due to the presence upon Mars of that deathless Virginian, John Carter, whose miraculous transportation to Mars occurred March 4th, 1866, as every school child of the twenty-first century knows. Had not the little band of Martian scientists, who sought so long to communicate with Earth, mistakenly formed themselves into a secret organization for political purposes, messages might have been exchanged between the two planets nearly half a century before they were, and it was not until they finally called upon John Carter that the present inter-planetary code was evolved.
Almost from the first the subject which engrossed us all
