Good one, Dave!
“How to let fall, perhaps
boneless as hope.”
was the passage which caught my fancy.
But what was this strange device?

I puzzled over ‘hand truck’
First I thought it was a toy
Then, perhaps a wheely barrow
Pushed nose down. Quite shy and coy
But the walking backwards passage
Blew that image all to heck
Cause I’ve tried that with a barrow
And I wove a wavy trek
So I accessed Wikipedia
And why there it was, by golly
It’s a super leverage buy
Out round these parts
It’s called a “dolly.”
