At the worst, I'd have had a run for my money." She went on without smiling: "And even trains run off the track sometimes. Do you think you would enjoy the memory of a railroad accident—even if you weren't hurt yourself?" "Perhaps not. But there's another disadvantage of the train. It's so regular and mechanical that if anything does go wrong there is an ugly smash. It's the same way with modern people. Most of us live such an ordinary habitual life that if we get thrown off the track we're likely to break up altogether."[Pg 13] [Pg 13] I had struck the wrong note again. The light went out in her face, as a cloud-shadow darkens a sunny field, and she looked away without answering. Not to make my mistake worse by taking notice of it, I said, "After all, what should we do if things always went smoothly and there weren't any adventures?" She said quietly, "We might be normal and wholesome and comfortable," and continued looking out of the window and toying with her chain, while I cursed myself for a tactless clodhopper without the sense to avoid a danger sign. Then I found myself wondering what this trouble could be that by the mere touch of an accidental allusion could strike the joy out of a creature so naturally radiant.

She roused herself presently, and the talk went[Pg 14] on, though with an undercurrent of discomfort. For my part, I was still repenting my clumsiness; and she, I suppose, felt annoyed at having shown so palpably an emotion which she had not intended for my eyes. So that, in spite of regret for the approaching end of the adventure, I was hardly sorry when our arrival at Stamford supplemented speech with action. [Pg 14] "Are you expecting any one to meet you?" I asked, as the platform emptied and left us standing alone. "No, they didn't know what train I was coming on. But there's the trolley now. And it's your car, too, that is, if you're still going to the Ainslies'." A
