[Help-bash] Using single quotes to escape a newline

[Michael Convey]

According to: Newham, Cameron (2005-03-29). Learning the bash Shell: Unix

"Whether you use a backslash or a single quote, you are telling the shell
to ignore the special meaning of the RETURN character."

However, when I try to use single quotes to escape a newline, the newline
is not escaped, as follows:

$ echo 'the fox
> ran down the hill'
the fox
ran down the hill
$

Has the ability of single quotes to escape a newline changed since this
book was written?
