At McGuffey elementary school in old north Dayton, Ohio, we learned this version in the early 1940s:

Across the plain of gold and green a young boy plainly can be seen A huya huya huyaya swiftly tumbling waters A huya huya huyaya swiftly tumbling waters

But no, 'tis not a boy at all 'Tis Ifca's castle's spire so tall repeat chorus

I'm now 74 years old, have never forgotten this song, and still don't know anything about Ifca!
