position of map section HM-243-839, setting their magazines for twenty shots, and pressing their fire buttons.

For what seemed an interminable instant nothing happened.

Then several miles to the southeast, an entire section of the country literally blew up, in a fiery eruption that shot a mile into the air. The concussion, when it reached me, was terrific. The light was blinding.

And our scopemen reported the instant annihilation of the squadron.

What happened, of course, was this; the Hans knew nothing of our ability to see at night through our ultroscopes. Regarding itself as invisible in the darkness, and believing our instruments would pick up its location when its dis rays went into operation, the squadron made the fatal error of not turning on its canopies.

Their next attempt was made in daylight. I was aloft in my swooper at the time, hanging motionless about a mile up. Below, the groundships looked like a number of oval lozenges gliding across a map, each surrounded by a circular halo of luminescence that was its dis ray canopy.

They had nosed up over the spiny ridge of what once had been Jersey City, and were moving across the meadowlands. There were twenty of them.

Coming to the darker green that marked the forest on the "map" below me, they adopted a wedge formation, and playing their pencil rays ahead of them, they began to beam a path for themselves through the forest.
