Lassoharp reminded me of this fine antique text, which I now require all of you to read. I'm sure it's been posted here before. Fits the layman, and reminds the not-so-layman. Reads like PRR in many ways, but is a bit funnier, with less numbers. How does that grab you? Of course it's of the tube era, but has a billion lessons pertinent today. It's a fast easy read. Dates as 1950, but I think this appeared as a series of magazine articles several years earlier.
