I converted the .epub to .mobi. The .pdf might work too. One problem is that the .epub is all one chapter, instead of having a separate chapter for each section based on the table of contents. That could be fixed by making the sections into subpages on Wikisource, but I am not inclined to do that.
Great job! It looks like .epub is not supported on the Kindle though? Should I use the .pdf or convert to .mobi?
