It was late when we arose from the supper-table, and the Captain and my husband left us, to go down to the guard-house, while Mrs. Arnold led me into the room where their bed stood. This room had but one window--of which window the Captain was very proud. It was a _French_ window, opening down to the ground. Throwing it open, Mrs. Arnold said:
"What a beautiful moon we have to-night; let us put out the candle and enjoy the moonshine"--with which she laughingly extinguished the light, and drew my chair to the window.
From where I sat I could just see the men's quarters and the guard-house, though it might have been difficult from there to see the window. We had not been seated long when I fancied I heard a noise, as though of some one stealthily approaching from somewhere in the direction to which my back was turned; then some one seemed to brush or scrape against the outside wall of the house, behind me. "What's that?" I asked in quick alarm. It had not remained a secret to Mrs. Arnold that I was an unmitigated coward; so she arose, and saying, "How timid you are!--it is the dog; but I will go and look," she stepped from the low window to the ground outside, and vanished around the corner of the house. Some time passed before she returned, and with a little shudder, sprang to light the candle.
"How chilly it is getting," she exclaimed; and then continued, "it was the dog we heard out there. Poor fellow; perhaps the cook had forgotten him, so I gave him his supper."
Rising from my seat to close the window on her remark about the cold, I stepped to the opposite side from where I had been sitting; and there, crossing the planks that lay over the slimy creek, and going towards the commissary buildings, was a man whose figure seemed familiar: I could not be mistaken--it was Lieutenant Rockdale. No doubt the man had a right to walk in any place he might choose; but, somehow, I could not help bringing him in connection with "the dog, poor fellow," for whom Mrs. Arnold had all at once felt such concern.
Soon the gentlemen returned, and we repaired to the parlor, where a game of chess quickly made them inaccessible to our conversation. The game was interrupted by a rap at the front door, and Harry, the sergeant whom Mrs. Arnold had compelled to mount her black horse that day, appeared on the threshold. In his face there was a change, too; his eyes flashed with an unsteady light as he opened the door, and ever and again, while addressing the Captain--whose thoughts were still half with the game--his looks wandered over to where Mrs. Arnold sat. We were so seated that the Captain's back was partly toward her when he turned to the sergeant; and he could not see the quick gesture of impatience, or interrogation, that Mrs. Arnold made as she caught the mulatto's eye. Involuntarily, I glanced toward him--and saw the nod of assent, or intelligence he gave in return.
