According to The Annotated Mother Goose, "This rhyme would seem to refer to the 'promenade' of marriageable maidens... such a 'promenade' usually took place after church on a Sunday. The 'marriageable maidens' strolled while the young bloods of the town looked them over with an eye to selecting a future wife."

Notes

The Real Mother Goose (1916), illustrated by Blanche Fisher Wright, has this rhyme as follows:

Around the green gravel the grass grows green,
And all the pretty maids are plain to be seen;
Wash them with milk, and clothe them with silk,
And write their names with a pen and ink.

The Annotated Mother Goose (1962), edited by William and Ceil Baring-Gould, has the same version as The Real Mother Goose just above, with the note, "In later versions, the last line reads:

'And the first to go down shall be married.'"

The rhyme makes the most sense putting that all together:

Around the green gravel the grass grows green,
And all the pretty maids are plain to be seen;
Wash them with milk, and clothe them with silk,
And write their names with a pen and ink.
And the first to go down shall be married.
