looking for an essay by Thoreau on ants, not that one

[AlphaDog]

When I was searching, "Where I Lived and What I Lived For" was as close as I could get. I don't have a clue if it's what you're looking for, though. It's been so long since I've read any Thoreau that what you're referring to doesn't even sound familiar.
