The pictures above are from glass negatives in the Bancroft Library Hopedale history collection. They were evidently taken by Edwin Darling who lived at 54 Freedom Street.
The photo below is from an album at the library. The pictures in it were probably also taken by Darling. I’ve included it so you can see where the other pictures were taken from. The house at the left was the Roper house at 50 Freedom Street. The one next to it was the Darling house. The white house in the middle was a duplex built by Henry Patrick for his employees. Mrs. Darlilng’s parents lived in the one to the right of that. This is obviously a very early view of the park. I don’t think it could have been taken any later than 1900.
