Dear Mr. Editor, It hailed on Memorial Day this year. On an Austin afternoon when the temperature reached 100 degrees, ice actually fell from the sky. At the time I thought that it might have been an omen of some import, but it was not until now that I discovered why: Robert Burns had died. Louis Black detailed Robert's public accomplishments ["Page Two," June 4], but I never worked with him; to me he was just a good friend, and I will miss him. He was literate and witty (Robert always maintained that he had a brother named Rug Burns) and he possessed one of the sharpest minds I knew. Let me give you one example. I will never forget a conversation that I had with Robert back in 1991 about palindromes. Palindromes are, as you know, words or phrases that are identical when spelled backward, like "dad" or "level" or "gateman's nametag." I mentioned the longest palindrome that I knew ("A man, a plan, a canal – Panama!") and remarked to Robert that, at 21 letters long, it would be difficult to come up with a longer one. He then gave me a six-line poem that he had recently written. It is in free verse and is a palindrome of 73 letters, quite possibly the longest palindrome in the English language. This is Robert Burns' palindromic poem: Sure, vote. Go there, gnaw. A rat race! We fill a minimal life. We cart a raw anger, eh? To get over ... us.
