During the brief war with the Martians upon the earth it had been gunpowder against a mysterious force as much stronger than gunpowder as the latter was superior to the bows and arrows that preceded it.
There had been no comparison whatever between the offensive means employed by the two parties in the struggle on the earth.
But the genius of one man had suddenly put us on the level of our enemies in regard to fighting capacity.
Then, too, our electrical ships were far more effective for their purpose than the projectile cars used by the Martians. In fact, the principle upon which they were based was, at bottom, so simple that it seemed astonishing the Martians had not hit upon it.
Mr. Edison himself was never tired of saying in reference to this matter:
"I cannot understand why the Martians did not invent these things. They have given ample proof that they understand electricity better than we do. Why should they have resorted to the comparatively awkward and bungling means of getting from one planet to another that they have employed when they might have ridden through the solar system in such conveyances as ours with perfect ease?"
"And besides," Mr. Edison would add, "I cannot understand why they did not employ the principle of harmonic vibrations in the construction of their engines of war. The lightning-like strokes which they dealt from their machines are no doubt equally powerful, but I think the range of destruction covered by the disintegrators is greater."
However, these questions must remain open until we could effect a landing on Mars, and learn something of the condition of things there.
The thing that gave us the most uneasiness was the fact that we did not yet know what powers the Martians might have in reserve. It was but natural to suppose that here, on their own ground, they would possess means of defense even more effective than the offensive engines they had employed in attacking enemies so many millions of miles from home.
It was important that we should waste no time, and it was equally important that we should select the most vulnerable point for attack. It was self-evident, therefore, that our first duty would be to reconnoiter the surface of the planet and determine its weakest point of defense.
