It occurred to none of the actors, and to Marta alone, in the tight, foreboding silence, to look aloft.  There was a serene blue sky.  The birds were tuning up for their morning songs when she heard the dull echo of distant guns, soon to be submerged in other thunders at nearer points along the frontier.  With every faculty an alert wire strung in suspense, she was instantly aware of the appearance of a figure whose lack of uniform made it conspicuous on that stage.

In straw hat and blue blouse, shuffling with his old man’s walk, Feller came along the path from the gate.  He was in retreat from the enticing picture of the regiment of field-guns in front of the castle that was ready for action.  As the infantry had never interested him, he would be safe from temptation in the yard.  He stopped back of the engineers, his glance roving down the line of brown shoulders until it rested on the automatic.  This also was a gun, though it fired only bullets.  His fingers began beating a tattoo on his trousers’ seam; a hungry brilliance shone in his eyes.  He took four or five steps forward as if drawn by an overpowering fascination.

“This is no place for you!” said one of the engineers.

“No, and don’t waste any time, either, old man!” said another.  “Back to your bulbs!”

Feller did not even hear them.  For the moment he was actually deaf.

“Fire!” said Dellarme’s whistle.  “Thur-r-r!” went the automatic in soulless, mechanical repetition, its tape spinning through the cylinder, while the rifles spoke with the human irregularity of steel-tipped fingers pounding at random on a drumhead.  All along the line facing La Tir the volume of fire spread until it was like the concert of a mighty loom.

Marta could see nothing of the enemy, but she guessed that he was making a rush from the second to the third terrace and from the outskirts of the town.  The engineer’s repeated warning unheard above the din, he touched Feller on the leg.  Feller looked around with a frown of querulous abstraction just as the breaking of a storm of shell fire obscured Marta’s vision with dust and smoke.  She felt her head jerk as if it would go free of her neck with each explosion, until she reinforced her nerves with the memory of an old soldier’s warning about the folly of dodging missiles that were already past before you heard them.  She knew that she was perfectly safe behind the pillar.

The Gray batteries having tried out their range by the flashes of the automatic the previous evening were making the most of the occasion.  “Uk-ung-n-ng!” the breaking jackets whipped out their grists.  A crash on the roof brought a small avalanche of slate tumbling down.  A concussion in the dining-room was followed by the tinkling of falling window-glass.  The engineers had work immediately when two of the infantrymen and their rifles and the sand-bags on which they leaned were hurled together in a heap of sand and torn flesh.  Other bags were placed in
