"Only on our slow trains," replied O'Brien. "To put speed recorders on Paddy McGraw or Jimmie the Wind would be like timing a teal duck with an eight-day clock. Sir?" he asked, turning to another questioner while the laugh lingered on his side. "No; those are not really mountains at all. Those are the foothills of the Sleepy Cat range--west of the Spider Water. We get into that range about two hundred miles from here--well, I say they are west of the Spider, but for ten days it's been hard to say exactly where the Spider is.
