Hi chesilbeach, thanks for finding those links, I was beginning to think my memory was playing tricks on me. Looking at some of those prices I should have kept a couple of copies when we were reading them at school!
When I was at junior school in the 60s we read a book that I thought was called "Chang". It was about a boy and an elephant and the place where elephants go to die. I wanted to find it for my grandson to read but after Googling and searching on Amazon I can't find any record of it. Can anyone help please?
