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.
