“We are ready to make you that promise, sir,” he told the commander of the Uhlans, “in fact, we should have decided on that course long ago. It would have saved us a heap of trouble. Once across the border and on Dutch soil we should not have crossed back again.”

“I differ with you there, boy,” said the other, smiling again; “for had you done so the German flying corps would perhaps have lost its most brilliant and daring exponent. Turn your car, therefore, and you can proceed ahead of us. First of all let me mark out the course I wish you to take.”

With that he drew out a map of Belgium and Holland. Thad was interested when he saw what a marvel of ingenuity that map was. It had evidently been carefully prepared for the army to be used in case of just such an invasion. Possibly there were other charts covering Great Britain, France, Russia, Italy, Switzerland and Denmark.

Thad saw that it was very minute. Not a railroad, station, crossing, canal, road, town, village, bridge, ford, fort or anything else of consequence but that it was plainly marked there. And the officer had other maps too, for Thad glimpsed them when he was selecting this one.

He traced the route back to the Dutch border, and Thad, taking out his own apology for a chart, made marks to indicate the course he was to take. Then after considerable work he managed to get the car turned, some of the troopers being ordered to dismount and lend a helping hand. After that they started, and before they had gone far the clatter of horses’ hoofs from the rear announced that the entire squadron of troopers must be coming after them.

“Gee! but I’m glad they’re not meaning us any harm,” remarked Giraffe, as he took one of his usual backward peeps by simply twisting that long neck of his around; “because they’d be able to overtake us in a jiffy, even if their nags are tired. It’s a heap nicer to have these hard-riding Uhlans for friends than enemies. And I also hope we don’t run afoul of that armored motor-car we saw, with those reckless Belgians in the same. I do believe they’d charge the whole Uhlan squadron.”

Thad himself echoed that wish. He had seen sights during that terrible battle for the possession of the disputed bridge that would never fade from his memory; and he did not want to look on anything further that had to do with bloodshed and misery, under the thin veneering of glory.

“We’re coming to the side road he wants us to take, and which will lead to the Dutch border,” Thad announced after a time.

A few minutes later and the car turned to the left, after which Thad shut down. Standing up they watched the troop gallop past, and fortunately the dust was blowing toward the opposite quarter so their view was not hindered. The scouts had taken off their hats, and every time they saw any one in that long column give them a salute they answered in kind as they had been taught by the rules of the organization to which they belonged.

Finally the last Uhlan had ridden past, and only a slowly settling cloud of dust told where they had gone.
