What do 'bet money on money' and 'I’m for money against the field' mean?
“Now, don’t say that,” said old Anthony, shocked. “I bet my money on money every time. I’ve been through the encyclopedia down to Y looking for something you can’t buy with it; and I expect to have to take up the appendix next week. I’m for money against the field. Tell me something money won’t buy.”
