"They're fighting hard," conjectured Blaine. "Guess wrecking them sausages must 'a' stirred Fritzy up a bit. Hullo! What's that?" Already Lafe was a thousand or more feet up. The field battery was now fading from view as the flames of the burning plane died down. CHAPTER VIII BLAINE'S FURTHER ADVENTURES Once more sharp reports from the Archies came from below. Whether these were by the battery he had seen Lafe could not now tell. So thick was the fog, the gun flashings did not reach up to where he was now spiraling still upward, in order to get beyond the chance effect of some stray shot. All along the now distant battle line the dull red glow of bursting shells lined the front as the rumble of sound jarred more clearly upon his ears. Undoubtedly some kind of battle must be going on. Was it one result of the night raid? Was Fritz, now that his observation points were at least temporarily out of active service, taking his revenge by another drive? And where the Allies would least suspect? That is, right over the Appincourte Bluff? "What ought I do?" reflected Blaine, still gently climbing higher. "It's a still night, foggy, good for most anything up here, except to see or be seen and that's what I don't want. Wonder if poor Finzer had his night signals along? Ah, here they are!" He was overhauling with one hand a small locker that was part of the fuselage Moreover, there were still two unused sheafs of ammunition for the Lewis gun and a few grenades and bombs. Finzer had not expended all his allotment in the balloon attack. "Guess I'd better edge in towards where that drive seems to be centering. That is the reason, probably, that this battery broke in where I was on the point of going up again. Fritz is up to some new thing, I'll bet." Taking his bearings as best he could, Blaine headed more westward, keeping at an elevation of six or seven thousand feet. "Wonder what they'll think back at the station when they don't find me among the ones that get back? Poor Milt! I lost my machine; he lost his life. And there were others, too. That Montana chap Bangs. Last I saw of him he was right under one of them sausages, letting Fritz have it with the Lewis. Looked like something would get him -- heigho! What is that?" Down below, slightly to his rear, there flashed through the fog a short series of vari-colored lights, which to Blaine's active mind spelled forth: "Boches 'bout to get me. Big drive on hand. Yonder they go -- watch out!" That was all, but it was enough. Blaine knew that it must come from another of the raiding scouts who had somehow gone down in No-Man's-Land. It might come from a shell hole. Anyway, it was being sent up by some one risking almost certain death in order to let the Allies know that big things were already under way.
