Many things came over him here, and one of them was that he should doubtless presently know whether he had been shallow or sharp. Another was that the balcony in question didn’t somehow show as a convenience easy to surrender. Poor Strether had at this very moment to recognise the truth that wherever one paused in Paris the imagination reacted before one could stop it. This perpetual reaction put a price, if one would, on pauses; but it piled up consequences till there was scarce room to pick one’s steps among them. What call had he, at such a juncture, for example, to like Chad’s very house? High broad clear—he was expert enough to make out in a moment that it was admirably built—it fairly embarrassed our friend by the quality that, as he would have said, it “sprang” on him. He had struck off the fancy that it might, as a preliminary, be of service to him to be seen, by a happy accident, from the third-story windows, which took all the March sun, but of what service was it to find himself making out after a moment that the quality “sprung,” the quality produced by measure and balance, the fine relation of part to part and space to space, was probably—aided by the presence of ornament as positive as it was discreet, and by the complexion of the stone, a cold fair grey, warmed and polished a little by life—neither more nor less than a case of distinction, such a case as he could only feel unexpectedly as a sort of delivered challenge? Meanwhile, however, the chance he had allowed for—the chance of being seen in time from the balcony—had become a fact. Two or three of the windows stood open to the violet air; and, before Strether had cut the knot by crossing, a young man had come out and looked about him, had lighted a cigarette and tossed the match over, and then, resting on the rail, had given himself up to watching the life below while he smoked. His arrival contributed, in its order, to keeping Strether in position; the result of which in turn was that Strether soon felt himself noticed. The young man began to look at him as in acknowledgement of his being himself in observation.
