Good afternoon, welcome to Marsha plantation.(71)My name is Susan. I’ll be leading the tour today. The terrific plantation you are about to see was founded in 1830 by historic Paul Watson who was a cotton farmer. Later his family sold the plantation to the Mississippi produce company which closed down in 1959.(72)Then, the plantation was purchased by the government, which turned it into this living history museum. In a moment,(73)we’ll be leaving the house and heading to the souvenir shop.
