So it was decided that their little joint store, their savings, as one might say--their standing capital of _chance_ which they had improved and added to--should be invested in the hazardous business of rescuing a daughter of France from her German captors. It was _giving_ with a vengeance. It is a pity that there was no button to signalize this kind of a contribution. CHAPTER XXIX CAMOUFLAGE They turned westward now in a direction which Tom thought would bring them about opposite the Alsatian town of Norne. A day's journey took them out of the forest proper into a rocky region of sparse vegetation from which they could see the river winding ribbonlike in the distance. Beyond it in the flat Alsatian country lay a considerable city which, from what old Melotte had told them, they believed to be Mulhausen. "Norne is a little to the south of that and closer to the river," said Tom. They picked their way along the edge of the palisades, concealing themselves among the rocks, and as they thus worked to the southward the precipitous heights and the river converged until they were almost directly above the water. At last, looking down, they saw upon the narrow strip of shore directly below them the old castle of which Melotte had told them. There was no other in sight. From their dizzy perch among the concealing rocks they could see almost the whole width of southern Alsace in panorama, as one sees New York from the Palisades of the Hudson, and in the distance the dim outlines of the Vosges mountains, beyond which lay France. Not far from the river on the Alsatian side and (as old Melotte had said) directly opposite the castle, was a small town which Tom studied carefully with the glass. "That's it," he said, relieved, for both of them had harbored a lingering fear that these places existed only in the childish mind of the blue-eyed old weaver. "Melotte was right," he added. "Wait a minute--I'll let you look. You can see the new road and people working on it and--wait a minute--I can see a little flag on one house." There was no doubt about it. There was the town of Norne, and just west of it a road with tiny figures distributed along it. Archer was all a-quiver as he took the glass. "I can see the house," he said; "it's right near the road, it's got a flag on it. When the light strikes it you can see the black spot. Oh, look, look!" "I can't look when you've got the glass," said Tom in his dull way. "I can see the battleline!" cried Archer. Tom took the glass with unusual excitement. Far across the Alsatian country, north and south, ran a dim, gray line, seeming to have no more substance than a rainbow or the dust in a sun-ray. Far to the north it bent westward and he knew its course lay through the mountains. But short of those blue heights it seemed to peter out in a sort of gray mist. And that was all that could be seen of that seething, bloody line where the destinies of mankind were being contended for.
