Each line has 8 beats, so it should be played like this:
Em Em Em Em G G G G
Em Em Em Em G G G G
D D D D G G G G
*I don't know all of the lyrics, but below is a sample of the third verse with the chords listed
right above the word at which they should be played.
I'm at Harvard Square Station just north of Boston-Town;
I'm pickin' my banjo and them Yankees gather 'round.
They wanna hear that high, lonesome sound.
Take me back to from where I'm bound.
