Famous quotes containing the words fish and/or stock:
“A harvest mouse goes scampering by,
With silver claws and silver eye;
And moveless fish in the water gleam,
By silver reeds in a silver stream.”

If he leaves it to nature to carry out the sentence.
I shall will to the common stock of air my breath
And pay a death tax of fairly polite repentance.”
