Poems
Context: Children, if you dare to think
Of the greatness, rareness, muchness,
Fewness of this precious only
Endless world in which you say
You live, you think of things like this:
Blocks of slate enclosing dappled
Red and green, enclosing tawny
Yellow nets, enclosing white
And black acres of dominoes,
Where a neat brown paper parcel
Tempts you to untie the string.
