For a first attempt with Book Designer, this is not bad at all: I know that it took me a while before I got the hang of the program.
Here are a few suggestions:
1.
The title for chapter 1 is currently:
BY
CHAPTER 1
And this also appears in the footers.
I suggest that you delete the “BY”, which is probably an editing error – and is either a misplaced title or subtitle. If you go to the tools menu, then select “element browser” you can find and delete (or amend) any incorrect titles or subtitles quickly. (The footer will then also appear correctly.)
2.
On p.4 (small font) there’s a problem: “coordinating” appears as "co & 246 # ; rdinating" rather than the intended "coördinating." This can be solved by setting the language as German and importing the Book Cleaner files.
I invariably set the language as German: Book Designer always works best in it.
3.
The emdashes (long dashes, the width of the character “m”) have come out as hyphens. This can be solved by importing the book Cleaner files. Also, when you have opened the “make Sony Book” pane, remember to check the box to leave the dashes “as it is” in the text.
4.
Italics. The PG source has used underscores to indicate passages which should appear in italics, _like this._ I see that you have replaced some of the underscores with italics, but there are some still underscored.
It does look much nicer if you replace the lot with real italics.
It can be done in BD. But it is probably faster to do this in Word.
Here’s an easy way to do it (which I copied from another post a long time ago. I’m afraid that I can’t remember whose it was, but it works):
Use _(*)_ (wildchars enabled) in the "Find" field. Then place your cursor in the "Replace" field and hit the More/Format/Font and select "Italic". Don't type anything in that field. Then "Replace all".
Then, write _ in the "Find" field (wildchars disabled). Be sure you remove the formatting instructions from the "Replace" field and that you haven't hit space bar in the field. "Replace all".
If something looks wrong after you did this properly, probably the problem is that one of the _italics was not closed in the *.txt. The number of underscores in the *.txt must be a pair.
5.
Footnotes. You’ve left them as you found them in the PG source: embedded in the text. That’s fine. But, as you get more experienced then you can use “Notes and links” in the edit menu to hyperlink them, so that they can go to the end of the book, if you prefer an uncluttered text.
If you search the forums you may find some useful advice. I learned a lot from HarryT's Book Designer tutorial:

Also I find that Stingo's Word Macro is very useful in converting Gutenberg Text files:

And many people find that =X='s BookCreator macro is also very useful:
