Book 104: Jones: Mark Twain Make Me Do It

I found one good description on Google Books.

One new boy at school is teased about the smell of manure, as he has to milk in the morning before school.

Set in Nebraska in the 1950s. Chapter Jackrabbit Vincent.

I don't know the complete book, but probably not (much) more of interest.

The author also wrote "The Farming Game". 2 mentionings of bibs, but obviously just 2 brief ones, set in modern times.

I had some  books before about smell, mainly of interest the smell of new denim in school.
