Geology
Mt. Sims, The Knife
[Verse]
A stream of lava
Formerly flowed over the bed of sea
Triturated recent shells and corals
Baked into hard white rock, a precarious matter
I found a curious little stony Cellaria
Each cell provided with a long toothed bristle
Capable of various and rapid motions
Simultaneous and can be produced by irritation
