The brigand ship suddenly moved its position! It rose up in a low flat arc, came forward and settled in the center of the valley where the carts and rail sections were piled, and the outside projectors newly mounted on the rocks.

The brigands now began laying the rails from the ship toward the base of our cliff. The chute would bring the ore down from the ledge, and the carts would take it to the ship. The laying of the rails was done under cover of occasional stabs from the electronic projector.

And then we discovered that Miko had made still another move. The brigand rays, fired from the depth of the valley, could strike our front building, but could not reach all our ledge. And from the ship's newer and nearer position this disadvantage to us was intensified. Then abruptly we realized that under cover of darkness bombs, an electronic projector and searchray had been carried to the top of the crater rim, diagonally across and only half a mile from us. Their beams shot down, raking all our vicinity from this new angle.

I was on the little flying platform which sallied out as a test to attack these isolated projectors. Snap and I, and one other volunteer, went. He and I held the shield; Snap handled the controls.

Our exit port was on the lee side of the building from the hostile searchbeam. We got out unobserved and sailed upward; but soon a light from the ship caught us. And the projector bolts came up....

Our sortie only lasted a few minutes. To me, it was a confusion of crossing beams, with the stars overhead, the swaying little platform under me, and the shield tingling in my hands when the blasts struck us. Moments of blurred terror....

The voice of the man beside me sounded in my ears: "Now, Haljan, give them one!"

We were up over the peak of the rim with the hostile projectors under us. I gauged our movement, and dropped an explosive powder bomb.

It missed. It flared with a puff on the rocks, twenty feet from where the two projectors were mounted. I saw that two helmeted figures were down there. They tried to swing their grids upward, but could not get them vertical to reach us. The ship was firing at us, but it was far away. And Grantline's searchbeam was going full power, clinging to the ship to dazzle them.

Snap circled them. As we came back I dropped another bomb. Its silent puff seemed littered with flying fragments of the two projectors and the bodies of the men.
