Hens have their gravel; gravel sticks
The way it should stick, in the craw.
And stone on stone is tooth
For grinding raw.
And grinding raw, I learn from this
To fill my crop the way I should.
I put down pudding stone
And find it good.
I find it good to line my gut
With tidy octagons of grit.
No loophole and no chink
Make vents in it.
And in it vents no slime or sludge;
No losses sluice, no terrors slough.
God,give me appetite
for stone enough.
