[X-Unix] question about 'find'

[Charles Howse]

$ find ~/bin -name \*.sh -maxdepth 1 -perm 0644 -exec chmod 744 {} \;

This works as expected (I found the '\;' part on a web site), but I'm not
sure why I have to use the '\' as the next-to-last character.
Can't find anything about it in 'man find'.
Can anyone enlighten me?
If I missed it in 'man find', please point me to the correct section.  :-)
