He pointed behind me with an aspect of such pale dismay, that I involuntarily glanced over my shoulder and started as if I had seen a veritable ghost; for, peering from the gloom of that inner room, I saw a shadowy face, with dark hair all about it, and a glimpse of scarlet at the throat. An instant showed me that it was only Robert leaning from his bed's-foot, wrapped in a gray army-blanket, with his red shirt just visible above it, and his long hair disordered by sleep. But what a strange expression was on his face! The unmarred side was toward me, fixed and motionless as when I first observed it,--less absorbed now, but more intent. His eye glittered, his lips were apart like one who listened with every sense, and his whole aspect reminded me of a hound to which some wind had brought the scent of unsuspected prey. "Do you know him, Robert? Does he mean you?" "Lord, no, Ma'am; they all own half a dozen Bobs: but hearin' my name woke me; that's all." He spoke quite naturally, and lay down again, while I returned to my charge, thinking that this paroxysm was probably his last. But by another hour I perceived a hopeful change, for the tremor had subsided, the cold dew was gone, his breathing was more regular, and Sleep, the healer, had descended to save or take him gently away. Doctor Franck looked in at midnight, bade me keep all cool and quiet, and not fail to administer a certain draught as soon as the captain woke. Very much relieved, I laid my head on my arms, uncomfortably folded on the little table, and fancied I was about to perform one of the feats which practice renders possible,--"sleeping with one eye open," as we say: a half-and-half doze, for all senses sleep but that of hearing; the faintest murmur, sigh, or motion will break it, and give one back one's wits much brightened by the permission to "stand at ease." On this night, the experiment was a failure, for previous vigils, confinement, and much care had rendered naps a dangerous indulgence, Having roused half a dozen times in an hour to find all quiet, I dropped my heavy head on my arms, and, drowsily resolving to look up again in fifteen minutes, fell fast asleep. The striking of a deep-voiced clock woke me with a start. "That is one," thought I, but, to my dismay, two more strokes followed; and in remorseful haste I sprang up to see what harm my long oblivion had done. A strong hand put me back into my seat, and held me there. It was Robert. The instant my eye met his my heart began to beat, and all along my nerves tingled that electric flash which foretells a danger that we cannot see. He was very pale, his mouth grim, and both eyes full of sombre fire,--for even the wounded one was open now, all the more sinister for the deep scar above and below. But his touch was steady, his voice quiet, as he said,-- "Sit still, Ma'am; I won't hurt yer, nor even scare yer, if I can help it, but yer waked too soon."
