In preparing to teach Thomas Gray's "Elegy in a Country Churchyard," I came across the statement to "Direct attention to glosses 3 & 4."  I must admit that I have no idea what is being referred to.  What/Where are these glosses?  I have searched TeacherToolsOnline, the glossary (gloss?) at the back of the book, teaching helps, and even a Google search.  I have been unable to find out what I'm looking for.  I am even unable to find a way to ask BJU Press directly from TeacherToolsOnline (I can't find a chat or any contact information).  Any help on this matter would be greatly appreciated!!
