I read them in the 70's.
One was about a boy named Terry or Terence, and I even think the name of the book was Terence but I can't find it with google. The boy leaves home and lives by himself. I think he builds a shelter for himself by a river or stream.
The other one (this is a long shot) is a picture book and it involved someone making potions. It wasn't Disney or anything like that. I was 6 when I read it, and hid in the closet with the light on reading it over and over when I was supposed to be asleep. It was a library book so I didn't have much time with it. It must have been published in the 60s or early 70s, I think.
