“Since the raid is over with,” Frank commenced, “and the fleet bound for Dunkirk and Calais, where we understand the tired pilots will rest a few days before returning across the Channel, how would you like to have me take you out over the battle lines as we saw them yesterday?”

Pudge showed uncommon interest immediately. He had heard so much about the astonishing sights witnessed on that occasion by his two chums that it would always be a source of bitter regret to him should he have no opportunity to see the war picture for himself.

The Frenchman did not let a second go by, such was his eagerness to accept the proposition advanced by Frank.

“That is charming of you, I must say, young m’sieu,” he declared enthusiastically. “If you would be so kind it would place me under heavy obligations. To see how your wonderful Sea Eagle can act under new and novel conditions would complete my day, the most memorable of all my experiences, and they have been many, I assure you, messieurs.”

“Then there is really no need of our going down the coast any further,” Frank explained. “We might as well make a sharp turn to the east here, and say good-by to our gallant companions.”

As they did this, the action was noted by many of the speeding airmen; and while they could only guess at the object of the change, this did not interfere with their calling out and waving to the boys.

Looking back, Billy and Pudge could see the flock growing smaller in the distance as they scurried along like a covey of partridges. Well had they done their duty for the homeland on that day, and their hearts were beating proudly as they could see, in imagination, their names on the Roll of Honor for Britain’s sons.

Then Billy and Pudge tried to forget all about the late raid, for they knew they would have plenty of excitement to the square inch with what lay before them.

Just below where they broke away from the fleet of birdmen lay Ostend, basking in the February sunshine. It may have been fairly comfortable down there, but it was pretty cold half a mile up in the air, and the boys had reason to be thankful for their warm clothing and head hoods.

Attention was now called to the land over which they had commenced to fly, leaving the coast line behind. The Frenchman and Pudge in particular were observing everything with undisguised eagerness. While the experienced aviator had doubtless taken many a trip himself over just such a landscape, the conditions had never been just the same as they were now. As for Pudge, this was his baptism of fire in a seaplane, and as far as he had gone he rather liked it.
