"A pretty narrow escape, I should say!" chirped "Peewee," pleasantly, when the flurry had subsided.

"You bet! But for our record-breaking sprint we might have been caught," said Chase.

"Ha, ha!" laughed "Peewee." "Oh, my! Oh, my! Won't things be dull when we get away from here! It will seem so awfully odd not to have to shake in one's shoes and tremble every little while."

"I'd like to see a motion picture of ourselves crossing the road," chuckled John Weymouth.

"I wouldn't," giggled "Peewee."

Having satisfied themselves that the danger was all over, the crowd made a sortie. They saw the German airplanes sweeping around, preparatory to returning to their own lines. And as several of the machines reached a certain position in the sky the rays of the sun, now low in the west, streaming through an opening in the clouds, caught the wings, and for one brief instant they flashed and sparkled with a golden reflection.

Now flying at a much higher altitude, shells failed to reach their level, and very soon the airplanes became but faint purplish specks in the distance.

"I guess the war-birds are skimming back home fast so as not to get caught in the rain," laughed "Tiny" Mason.

Great masses of cumulus clouds were piling up in the west and the air which blew in their faces came in hot, fitful gusts. As time went on the whole aspect of the sky became more ominous and threatening, and at last lightning glimmered faintly just above the horizon.

"It's going to be Heaven's artillery pitted against man's to-night," remarked the art student, thoughtfully.
