The hills of oak and cedar are unusually green
The recent rains' effect on them thus easily seen
Yet the undergirding limestone structures of the land
Are not so easy to discern from where onlookers stand
We know that under soils thin the white chalk-stone is found
And porous stone that powders, breaks, makes for uneasy ground
If ever tremor shakes it. Though it has not happened yet
That it will never do so--I will never take that bet.
