Shade passed along a poem by Henry Reed, which I actually read awhile ago, but had completely forgotten about: Naming of Parts (.pdf + link).  In sequence, and by accident, I followed and found another part which I like even better.  Here’s the first part:

I. JUDGING DISTANCES

Not only how far away, but the way that you say it
Is very important. Perhaps you may never get
The knack of judging a distance, but at least you know
How to report on a landscape: the central sector,
The right of the arc and that, which we had last Tuesday,
And at least you know

That maps are of time, not place, so far as the army
Happens to be concerned—the reason being,
Is one which need not delay us. Again, you know
There are three kinds of tree, three only, the fir and the poplar,
And those which have bushy tops to; and lastly
That things only seem to be things.

It continues, and you can read it over here…
