The tune seems too short for the verse.
I would imagine that it's repeated for the second pair of lines (the 3 repeats of the first and third line are already covered in the music), but there doesn't seem to be anything for that fifth line "I'm going away to Marble town."

Although, there is a slightly different version @ ABC Notation where the line "True love, don't weep nor mourn for me," isn't included, going straight to "I'm going away to Marble town."

Cheers
