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 depths of the valley, could strike our front building, but could not reach all our ledge. And from the ship's new and nearer position this disadvantage was intensified. Then abruptly we realized that under cover of darkness-bombs an electronic projector and search-ray 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.


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-porte was on the lee side of the building from the hostile search-beam. 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.
