The Little Britches series (8 books) by Ralph Moody. Autobiography/recollections of growing up in Colorado (& elsewhere) in the early 1900’s. Great, wholesome, honorable tales of survival and family values during rough times. Lots of horse & outdoor stuff. I loved them when I was 10 and read and enjoyed them again in my 50’s.
I second the motion on Ralph Moody. Wonderful author. He spoke at the school where my dad was principal back in the early 60’s. I didn’t get to go, but Dad was very impressed. Man of the Family was my favorite in this series.
