George and I peered in all directions and could see nothing excepting the marvels of the universe we had been viewing. The moon now seemed very close and its craters and so-called seas were as plainly visible as in a four-inch telescope on earth. But we saw nothing of the enemy. The earth was a huge ball still, but much smaller than when I had first observed it from the heavens. The sun's corona--the flaming streamers which the professor declared extended as much as five million miles into space--was partly hidden behind the rim of the earth and the effect was blinding. A thin crescent of brilliant light marked the rim of our planet and the rest was in shadow, but a shadow that was lighted awesomely in cold green by reflected light from her satellite. "I have it!" suddenly shouted the professor. "We are all in very nearly the same line with reference to the sun, and the enemy is between the blazing body and ourselves. We must shift our position, move into the shadow of the earth. We have missed our calculation by a few hundred miles, that is all." All! I thought. These astronomers, so accustomed to dealing in tremendous distances that must be measured in light-years, thought nothing of an error of several hundred miles. But I suppose it was really an inconsiderable amount, at that. At any rate, we shifted position and looked around a bit more. We saw nothing at first. Then Hart consulted the chronometer. "Time is up!" he shouted. * * * * * On the instant there was a flash of dazzling green light from a point not a hundred miles from our position, a flash that was followed by a streaking pencil of the same light shooting earthward with terrific velocity. Breathlessly we followed its length, saw it burst like a bomb and hurl three green balls from itself which sped at equally spaced angles to form a perfect triangle. They hovered a moment at about two thousand miles above the surface of the earth, according to the professor, who was using the telescope at the time, and shot their deadly rays toward our world. We were too late to prevent the renewal of hostilities! Another and another streak of green light followed and we knew that great havoc was being wrought back home. But these served to locate the enemy's position definitely and we immediately set about to draw nearer. We were still somewhat on the dark side of the object, which had prevented our seeing it. Now we swung about so that it was plainly visible. And, what a strange appearance it presented, out here in space!
