I haven't heard of that poem, but the title sounds intriguing.
Good point about the illustration looking like a young Enid, although I guess that was a fairly standard look at that time.
I'm always amazed by stories from that era that show teenage girls wearing their school tunics (or their Guide uniforms) whenever out and about. I don't know if it was a true reflection of the time that they rarely wore anything else, other than perhaps their 'Sunday best'? I could understand it amongst the poorer classes who perhaps could only afford one set of clothes, but these are usually stories about girls living in large houses with tennis courts and servants!
Sorry, slipped off topic a bit.
