Along the narrow trench they rushed, carrying their machines which, it was hoped, would catch on the sensitive celluloid the scenes, or some of them, that were taking place in front. Mad scenes they were, too—scenes of bursting shells, of geysers of rock and earth being tossed high by some explosion, of men rushing forward to take part in the deadly combat.

As Blake had said, the scene was lighting up now. The sun rose above the mists and above the smoke of the guns, for though some smokeless powder was used, there was enough of the other variety to produce great clouds of vapor.

Behind the line of rushing soldiers, who were all firing their rifles rapidly, rushed the moving picture boys. They were looking for a spot on which to set their machines to get good views of the engagement.

"This'll do!" yelled Blake, as they came to a little hill, caused by the upheaval of dirt in some previous shell explosion. "We can stand here!"

"All right!" agreed Joe. "I'll go a little to one side so we won't duplicate."

The barrage fire had lifted, biting deeper into the ranks and trenches of the Germans. But they, on their part, had found the range more accurately, and were pouring an answering bombardment into the artillery stations of the French and Americans.

And then, as the sun came out clear, the boys had a wonderful view of what was going on. Before them the French and Uncle Sam's boys were fighting with the Germans, who had been driven from their trenches. On all sides were rifles belching fire and sending out the leaden messengers of death.

And there, in the midst of the fighting but off to one side and out of the line of direct fire, stood Blake, Joe and Charlie, the two former turning the handles of the cameras and taking pictures even as they had stood in the midst of the volcanoes and earthquakes, or in the perils of the deep, making views.

The fighting became a mad riot of sound—the sound of big guns and little—the sound of bursting shells from either side—the yells of the men—the shouting of the officers and the shrill cries of the wounded.

It took all the nerve of the three lads to stand at their posts and see men killed and maimed before their eyes, but they were under orders, and did not waver. For these scenes, terrible and horrible though they were, were to serve the good purpose of stimulating those at home, in safety across the sea, to a realization of the perils of war and the menace of the Huns.
