"You have now!" added the Flight-Sub.

CHAPTER XXVI

Disabled in Mid-air

Ross climbed agilely into the observer's seat, and, at his flying companion's suggestion, buckled a broad leather strap round his waist. At his right hand was the wireless transmitter, together with a pair of prismatic glasses and map. The latter was held in a transparent celluloid case, while the glasses were secured by a cord sufficiently long to enable the observer to use them in any direction. Everything was attached to the sea-plane so that in the event of the machine having to "loop the loop" nothing would be lost.

The Sub, who for the present was to act as pilot, took his place in the forward part of the body. Giving a few preliminary touches to the mechanism, he announced that everything was in order.

The self-starter was released and the motor fired, causing the twin propellers to buzz smoothly and powerfully.

Ross waved his hand to his chum as the sea-plane glided away from the Capella, and from that moment his whole attention was centred upon the work on which he was engaged.

For nearly a hundred yards the sea-plane "taxied", rising lightly over the waves; then almost imperceptibly it glided upwards with an even motion. Ross could hardly believe he was flying until he saw the sea apparently receding from him.

"All right?" asked the Sub through the telephone that formed the only audible means of communication between pilot and observer. "Not feeling giddy?"
