A second turn brought us into a square, brilliantly lighted, and overflowing with life. The old manner of the stranger reappeared. His chin fell upon his breast, while his eyes rolled wildly from under his knit brows, in every direction, upon those who hemmed him in. He urged his way steadily and perseveringly. I was surprised, however, to find, upon his having made the circuit of the square, that he turned and retraced his steps. Still more was I astonished to see him repeat the same walk several times—once nearly detecting me as he came around with a sudden movement.

In this exercise he spent another hour, at the end of which we met with far less interruption from passengers than at first. The rain fell fast, the air grew cool; and the people were retiring to their homes. With a gesture of impatience, the wanderer passed into a by-street comparatively deserted. Down this, some quarter of a mile long, he rushed with an activity I could not have dreamed of seeing in one so aged, and which put me to much trouble in pursuit. A few minutes brought us to a large and busy bazaar, with the localities of which the stranger appeared well acquainted, and where his original demeanor again became apparent, as he forced his way to and fro, without aim, among the host of buyers and sellers.

During the hour and a half, or thereabouts, which we passed in this place, it required much caution on my part to keep him within reach without attracting his observation. Luckily I wore a pair of caoutchouc over-shoes, and could move about in perfect silence. At no moment did he see that I watched him. He entered shop after shop, priced nothing, spoke no word, and looked at all objects with a wild and vacant stare. I was now utterly amazed at his behavior, and firmly resolved that we should not part until I had satisfied myself in some measure respecting him.
