The wallers said
"To talk of many things
Of running joints
And hammer heads
And how a struck stone rings."
"Of shale and schist, avoiding
cracks
cracks
And amethyst and slates,
And why debris forms mountain scree
And why the earth has plates"
"We'll speak of sub-atomic mass
Of particles and strings,
Of quantum leaps and isotopes
And earth's magnetic rings."
"And when we're done and figured out,
The universe and all,
We'll still be no where near agreed
How best to build a wall. "
