Mr. Wright, sometimes the "ivory tower" intellectual lacks practical experience.

I received a few months ago a pamphlet from a (no doubt) wise, learned and good intentioned professor advising me on the best way to raise baby chicks (I've been in the business all my life).  I dutifully read the pamphlet and ended up annoyed.

He gave advice on heating the barns (I respectfully submit I know more about my barns than the gentleman) - some the way I do things, some the way I don't for various reasons.  Some not unreasonable advice on feed and water.

The good doctor also made some downright screwy suggestions like checking the rectal temperature of a representative sample of 20 - 50 chicks per floor per day - a pointless waste of time not to mention an undesirable way to spend it.

I couldn't help but get the image (fairly or unfairly) of a veterinarian puttering around a small flock in a laboratory extrapolating his observations mistaken about their practical import elsewhere.
