Reading "Adventures of Huckleberry Finn" on Project Gutenberg I come across a sentence I can't quite comprehend. Also, word "googling" caught my eye:
whilst he made all sorts of signs with his hands and said "Goo-goo—goo-goo-goo" all the time, like a baby that can't talk
The duke he never let on he suspicioned what was up, but just went a goo-gooing around, happy and satisfied, like a jug that's googling out buttermilk.
I would thought it's an OCR error, and something like "gurgling" meant instead, but there is a scanned page adjacent to the text, with the same word in print: http://www.gutenberg.org/files/76/76-h/76-h.htm
So, I am eager to know the meaning of the word "googling" in this context(this answer weren't of much help). Also, it would be nice to get the meaning of the whole idiom "like a jug that's googling out buttermilk".
