"BOYLE:
I seen things, I seen things, Joxer, that no mortal man should
speak about that knows his catechism. Ofen, and ofen, when I was
fixed to
the wheel with a marlin-spike, an' the wins blowin' fierce an' the
waves lashin' and lashin' till you'd think every minute was goin' to
be your last, an' it blowed and blowed - blew is the right word,
Joxer, but blowed is the word the sailors use....
JOXER:
Aw it's a darlin' word, a daarlin' word.
BOYLE:
An' as it blowed an' blowed, I ofen looked up at the sky an'
assed meself the question - what is the stars, what is the stars?
JOXER:
Ah, that's the question, that's the question - what is the stars?
BOYLE:
An' then, I'd have another look, an' I'd ass meself - what is the
moon?
JOXER:
Ah, that's the question - what is the moon, what is the moon?"
