Patricia, I am fairly sure that the only way to be 100% sure would be to ask the copyright holder (D. Wyllie) for permission, unless it's obvious that you can copy and transcribe his work (as in CC licensed works). But then again, PG mentions in their FAQ that it's generally OK to make copies of copyrighted PG publications as long as you do so without commercial profit.
From PG FAQ, C.17.2:
Translation is a common and justified special case of a new edition. When someone translates a public domain work from one language to another, they get a new copyright on the translation (but not on the original, of course, which stays in the public domain so that lots more people can use it.)
From PG FAQ, C.24:
I see some Project Gutenberg eBooks that are copyrighted. What's up with that?
Authors or publishers may grant Project Gutenberg an unlimited license to republish their works. In this kind of case, the copyright holders still retain their rights, but grant permission for us to share these eBooks with the world.
These copyrighted PG publications can still be copied, but the permissions granted are spelled out in their headers, and usually forbid anyone to republish them commercially.
