Free Falling Divisions

Warning, warning
Free-falling divisions
Recalling recalling
Fast past admissions
Foolish words
No nervous laughter
Safety first
Gives always after

Drag my canal
You saucy old salt
Pale in belief
I'm not without fault

Scaffolding climber
Rudolf roof-walker
Aids binocular
Clear a path Jonah
Experienced water
Water transporter
Marine slaver
Experiment in coda
