On the present occasion, the emperor was standing alone, as I have said; his back resting against the wall, and a crowd of the most persistent gazers around. He looked vexed--even melancholy. They would not grant him this casual moment of amusement untormented. He had the air of one at bay. He faced the crowd full, and wherever his glance fell, I could see all eyes sink before it immediately. It rested a moment on myself. I had often heard, and often read, that it was difficult to return his look; and why I know not. It is but an eye; yet, whether it was the involuntary sympathy I felt for a king thus bayed in his moments of relaxation, or whether it was that in his piercing glance, there is an expression as if he were about to address you, and thus to make you the object of universal notice, or whatever else it may be, I too dropped my looks to the ground. A couple of masks approached him as if to speak; he turned full upon them, to give the opportunity; their hearts failed them at once, and with a low courtesy, they shrank back again. I saw him again several times during the evening, once walking with a lady (deeply masked, if I remember). His dress was that of a general officer, and he wore a lofty hussar's cap, with a single tall feather at its side. It made his stature seem still more colossal. As I was defiling through the crowd, I felt shortly afterward a sharp blow on my elbow. Turning, I saw a mask, who, looking at me for a moment, retreated. I followed till my guide had sat down in a place where there was room for two, making me to understand that I was to occupy the vacant spot. I considered her figure for a moment, and then feeling perfectly sure that it was not that of an acquaintance, I declined. Without any answer, I strolled my way. Having seen what a masquerade was at the "_Nobles' Hall_," I soon afterward left the rooms altogether, hoping sincerely that the proceeds might be ample, for the sake of the veteran invalids; and meditating much on the Czar, whom I had had so good an opportunity of seeing, and whom these veterans regarded as by right divine their perpetual "Generalissimo."
