Don Hale certainly had a very unpleasant prospect before him. Responsibility shared is that much lessened; but, bravely holding his feelings in check, he guided Number Eight with a firm hand.

"I hope to goodness no more adventures are in store for me to-night," he thought, grimly.

Reaching the scene of the catastrophe, the car bumped and floundered heavily over places where the explosion had torn up the road-bed.

The "empties" were still stalled, but the transports in advance had gone on their way; and for this Don felt very thankful, as it enabled him to make better speed.

Around another bend—then Number Eight began mounting the rather narrow road which led over the hill just beyond. The roar of the big guns hidden in the forest was now almost incessant, and between the trees in the distance, through the clearing atmosphere, the ambulancier caught glimpses of flares and signal bombs rising above the German trenches.

Along this portion of the way he again encountered "arrivés," which were coming in pretty fast and still further devastating the forest, but so long as none of them landed within a few hundred yards or so the young Red Cross driver's mind was easy.

Finally the ambulance climbed over the summit and presently went slipping and sliding down the opposite slope. The lightning now cast only an occasional glimmer among the trees and the task of piloting the car down that wet and treacherous incline required all the skill Don Hale possessed. Not the faintest glimpse of horses, wagons or trucks could he see. It was taking chances with a vengeance. Nevertheless the young ambulancier, ever mindful of the serious nature of his mission, kept steadily on, while the forest all about him rang and reverberated with the thunderous reports of the big guns. A succession of rolling hills was passed in safety, and now the dreaded crossroad was being approached.

"The Germans are peppering it, all right!" exclaimed Don, aloud.

A marmite had just dropped on the heights above.

There are some things to which the nerves can never become accustomed. Don Hale felt his heart throbbing faster; he clutched the steering wheel with a stronger grip, and anxiously peered upward.
