Silence followed, as though all the human elements in that late wild tumult had managed to leave the scene of their defeat. Still Jack continued to swing around in a short circle, showing how even with the spoils of victory close within their reach he could keep to his standard maxim of “watch your step!”

Minutes passed, and it went without question that the penetrating gas must be well swept away by the night wind so that it would be safe for them to board their prize and take a quick inventory of the illicit cargo.

Perk knew the time for action had arrived when he felt the plane head toward the surface of the gulf, as though it was Jack’s intention to drop just back of the sloop’s stern when they could taxi alongside and readily climb to the low deck.

There was nothing surprising about their coming in contact with the surface of the water–Jack had acquired a habit of making perfect landings whether ashore or with pontoons. Knowing this, Perk never looked for anything else.

They came down with hardly any more of a splash than a pelican might have made and almost instantly Jack started taxiing ahead in the direction of the nearby anchored sloop.

Perk had set the third tear-bomb down with the belief that there would be no necessity for his using it. Silence hung about the sloop, and he had decided there could be no one around, unless, when they clambered over the side, they should discover some poor chap who had succumbed to the provoking gas or else been stunned by a blow in the wild melee that had raged previously.

Just the same wise old Perk did not mean to be caught off his guard and so he dragged out a formidable looking automatic, supplied by the Secret Service to all its accredited agents as a means for compelling a surrender on the part of any “wanted man” when overtaken in his flight.

The head-phones had been disconnected so there was nothing to hinder a prompt boarding of the captured boat when Jack gave the word. With the glorious flush of victory thrilling his whole frame Perk stood by to fend off as they drew close to the squatty stern. It would be his duty to clamber out on one wing and get aboard, carrying a rope by means of which the floating airship could be secured to the water craft.

This he managed to accomplish without much difficulty, wondering while so doing whether he and Jack might not be making history, for he suspected that never before in the annals of aviation had an amphibian plane been afforded a chance to take a prize of war in such an original fashion as bombarding the enemy crew with tear-gas bombs and causing them to flee in mad haste.

It was an exultant Perk who stood erect on the deck and waved his flying helmet with the proud air of a neophyte hunter planting his foot on the body of his first slain lion or tiger.
