"They're at us!" exclaimed the lieutenant. "Open fire on the parapet opposite, unless you see a better target, and don't leave your posts. Keep low. Better use the loopholes." He left the fire step and ran along the duck boards toward the heart of the row. Dick and Frank Sacobie and Hiram Sill, firing rapidly through the loopholes, added what they could to the disturbance. Now and again a bullet rang against the steel plate of a loophole. One or another of them took frequent observations through a periscope, for at that time the Canadian troops were not yet supplied with shrapnel helmets. Dave Hammer, breathless with excitement, joined them for a few seconds. "They tried to jump us,--must have learned we're a green relief,--but we've chewed them up for fair!" he gasped. "Must have been near a hundred of 'em--but not one got through our wire. Keep yer heads down for a while, boys; they're traversing our top with emmagees." At last the enemy's artillery fire slackened and died. Ours drubbed away cheerily for another fifteen minutes, then ceased as quick and clean as the snap of a finger. The rifle fire and machine-gun fire dwindled and ceased. Even the up-spurting of the white and watchful stars diminished by half; but now and again one of them from the hostile lines, curving far forward in its downward flight, illuminated a dozen or more motionless black shapes in and in front of our rusty wire. Except for those motionless figures No Man's Land was again deserted. The big rats ran there undisturbed. Sacobie looked over the parapet; Hiram Sill and Dick sat on the fire step at the Malecite's feet. They felt as tired as if they had been wrestling with strong men for half an hour. Dave Hammer came along the trench and halted before them. "Those Huns or Fritzes or whatever you call them are crazy," he said. "Did you ever hear of such a fool thing as that? They've left a dozen dead out in front, besides what they carried home along with their wounded--and all they did to us was wound three of our fellows with that first bomb they threw, and two more with machine-gun fire." "Their officers must be boneheads, for sure," said Hiram. "War's a business,--and a mighty swift one,--and you can't succeed in business without knowing something about psychology. Yes, gentlemen, psychology, queer as it may sound." "Sounds mighty queer to me!" muttered Sacobie, glancing down.
