Lighter grew the deep gorge and lighter still, and soon in glorious radiance the morning sunshine blazed on the lofty battlements far overhead, and every moment the black shadow on the westward wall, visible to the defense long rifle-shot southeastward, gave gradual way before the rising day god, and from the broader open reaches beyond the huge granite shoulder, around which wound the canon, and from the sun-kissed heights, a blessed warmth stole softly in, grateful inexpressibly to their chilled and stiffened limbs. And still, despite the growing hours, neither shot nor sign came from the accustomed haunts of the surrounding foe. Six o'clock was marked by Blakely's watch. Six o'clock and seven, and the low moan from the lips of poor young Chalmers, or the rattle of some pebble dislodged by the foot of crouching guardian, or some murmured word from man to man,--some word of wonderment at the unlooked for lull in Apache siege operations,--was the only sound to break the almost deathlike silence of the morning. There was one other, far up among the stunted, shriveled pines and cedars that jutted from the opposite heights. They could hear at intervals a weird, mournful note, a single whistling call in dismal minor, but it brought no new significance. Every day of their undesired and enforced sojourn, every hour of the interminable day, that raven-like, hermit bird of the Sierras had piped his unmelodious signal to some distant feathered fellow, and sent a chill to the heart of more than one war-tried soldier. There was never a man in Arizona wilds that did not hate the sound of it. And yet, as eight o'clock was noted and still no sight or sound of assailant came, Sergeant Carmody turned a wearied, aching eye from his loophole and muttered to the officer crouching close beside him: "I could wring the neck of the lot of those infernal cat crows, sir, but I'll thank God if we hear no worse sound this day."
