In the thoroughness with which the engineers were making fast their gains, a military observer would have read that not only would the Allied army draw the sting from this "empire of death," but that never again would this part of France be yielded to alien hands. As far as the eye could reach roads were being improved, others made; the buried railways were being excavated, metals straightened, or replaced if too far bent; shell-proof dug-outs were having their finishing touches, some to be used as dressing-stations for the wounded whom to-morrow might bring in, others for storing ammunition. In a nearby wood, where trees had been reduced to little more than gaunt trunks barren of leaf and twig, observation posts were built with many tons of branches hauled from the rear, and so artfully wired in place that the stricken giants seemed almost ready to live again. This work in itself constituted reason enough for the Allied airmen to sweep the sky of German observers, since only by "putting out the enemy's eye" could such secrets of camouflage be preserved. Wells were being bored by gas engine power and pipes laid, as spider webs, to bring untainted water to man and beast. Then, of course, shallow trenches had to be dug for telephone wires which otherwise would perish in the first onslaught of artillery fire.

Among the trenches of greater magnitude, recently pounded to the point of obliteration, activities were being pressed at highest tension, for here the destruction had been particularly severe. The Germans had held them well, but no human agency could have prevailed against the unfaltering valor of the Allies. Now they were in Allied hands, and being prepared for Allied shelter. From sunken approaches to the assembly trenches, and from there forward through an intricate maze of communicating passages to the firing trench, tens of thousands of men were busy with pick and shovel—not, however, constructing the narrow, steep-sided affairs which proved so disastrous to the Germans on the Somme, but a shallower type of trench having more flare and a wider sole. Just behind them worked the plumbers and pipemen, the carpenters and timber placers, the electricians with their coils of wire and telephones; everything perfected with the greatest nicety today, which tomorrow—or the next, or next, tomorrow—would be buried for future plowshares. War could not be war unless it were the highest expression of construction and destruction, even as it raises life and death to the highest power of sublimity!

Boring like huge worms from the front line outward, were tunnellers, biting into the earth with grim persistence to lay mines beneath the enemy; not that this work would be finished in time for tomorrow's action, wherein plans were already completed to press forward, but should the German positions prove firm enough to establish another temporary deadlock, then they would serve a purpose. By such forethought are battles won, when nothing is underestimated, nothing overlooked, no shade of opportunity neglected, and all chances accounted for.

"I never dreamed it was so gigantic a game as this," Jeb gasped.

"But there is much more, Monsieur," his companion smiled.

"Does no one ever rest?" Jeb asked, in a voice of awe.

"Oh, yes, Monsieur," the poilu smiled again. "In places where the trenches have been cleared and mended, where telephone wires have been connected to instruments, where water pipes have been brought down and fauceted, flooring built across mucky places, gas gongs installed, ammunition, grenades and tinned food stored in the newly finished shell-proof chambers, you will find a few over-exhausted men sprawled out, sleeping."

While Jeb could see nothing of this, the driver promised to get him into it soon enough—a suggestion that turned him away in search of other scenes and thoughts. Off to the right two lines of snags marked what had once been graceful poplars edging a famous route national, but now——! He glanced quickly backward along the direction from which he came. Here, at first, a brighter prospect met his eyes: the far-off rolling slopes were green, the far-off woods had not been stripped of leaves; but never could the grim story be quite wiped out for, across this verdant scene, as a long, thin reptile with a million legs, crawled an endless line of artillery and munition trains.

"Can't I ever get away from it!" he cried to himself, shutting his eyes in agony.

The horses had been rested and word came to proceed; the limbers creaked and moved. Jeb gripped the seat in terror, feeling now that before they got half way down the slope a German gunner would pick them out and touch the magic spring which reduces men—not symbolically but literally—to dust. Yet he breathed more freely and sent another prayer up for the engineers when almost at once they entered a sunken road, converging toward the enemy although keeping well out of sight. At places where the terrain did not admit of this shelter, or other roads went off at tangents, long strips of canvas were stretched across the openings, their outer sides being painted, in theatre scenery fashion, to represent the surrounding ground. If the Germans had only known that thousands of troops and thousands of tons of ammunition passed daily within easy range of their guns, protected by a wall of 10-ounce canvas! Another important reason for sweeping their planes from the sky!
