@greeting(Dear David:)
@begin(body)
	I have only had time for a superficial look at the paper
"Maintaining Knowledge of Temporal Intervals" by James Allen, and
I am returning it.

	My impression is that the paper is too argumentative; too
much space is spent on arguing a point of view relative to describing
what they have actually done; in one sense, too much of the paper
is advertising.  Apart from that I doubt the suitability of the
paper for CACM, since it treats a topic rather internal to AI.

Sincerely,




John McCarthy
Professor of Computer Science
