** Transcriber's Notes **

Underscores mark italics; words enclosed in +pluses+ represent boldface; words enclosed in /slashes/ represent underlined words. Words enclosed in ~tildes~ represent a wavy underline.

To represent the sentence diagrams in ASCII, the following conventions are used:

- The heavy horizontal line (for the main clause) is formed with equals
signs (==).
- Other solid vertical lines are formed with minus signs (—).
- Diagonal lines are formed with backslashes (\).
- Words printed on a diagonal line are preceded by a backslash, with no
horizontal line under them.
- Dotted horizontal lines are formed with periods (..)
- Dotted vertical lines are formed with straight apostrophes (')
- Dotted diagonal lines are formed with slanted apostrophes (`)
- Words printed over a horizontally broken line are shown like this:

——, helping
'————-

- Words printed bending around a diagonal-horizontal line are broken like
this:

\wai
\ ting
————-
