Pomp and Barney rushed into the cabin and came out with rifles. Harding also came with them.

“Give it to ‘em!” shouted Frank. “Don’t give them a chance to get the upper hand!”

“You bet we won’t,” cried Harding, with a thrill of resolution. “Mow them down, boys!”

The three rifles spoke.

The brigands were shot down like sheep. They returned the fire, but the defenders of the Kite were now all in the cabin and firing through loop-holes.

The destruction was most deadly.

The brigands tried to break in the cabin door. At this moment a happy thought came to Frank.

The Kite had been so constructed that its steel hull could be charged with electricity by pressing a certain key.

Those who were in the cabin, however, which was so arranged to be safe insulated territory, would not feel the shock.

Frank determined upon this method of repulsing the foe.
