We were ready—as ready as we could be with our meager equipment. The camp was in a state of siege. The cliff-lights were extinguished: the interior lights were dim, save in the workshops of the main building, where the final assembling of Snap's other flying platforms and their insulated protective shields was still in progress.

We had dimmed the lights to conserve our power, and to enable the Erentz motors to run at full capacity. Our buildings would have to withstand the brigand rays which soon would be upon us.

Outside on our dim, Earthlit cliff, the tiny lights showed where our few guards were lurking. As I stood at the window watching the oncoming ship, Grantline's voice sounded:

"Call in those men! Ring the call-lights, Franck!"

The siren buzzed over the camp's interior; the warning call-lights on the roof brought in the outer guards. They came running to the admission portes, which had been repaired after Miko disabled them.


he guards came in. We dimmed our lights further. The treasure sheds were black against the cliff behind us. No need for guards there—the bulk of the ore was such that we reasoned the brigands would not attempt to move it until our buildings were captured. But, if they should try it, we were prepared to sally out with our hand-weapons and defend it.

In the dim lights we crouched. A silence was upon us, save for the clanging in the workshop down the corridor. Most of us wore our Erentz suits, with helmets ready, though I am sure there was not a man of us but who prayed he might not have to go out. At many of the windows—our weakest points to withstand the rays—insulated fabric shields were hung like curtains.

The brigand ship slowly advanced. It was soon over the opposite rim of our little crater. Its search-beam swung about the rim and down into the valley.
