Horticulturist Kate Sessions arranges to lease 30 acres of land in San Diego, California for Balboa Park (originally called City Park), in exchange for planting 100 trees a year in the park and 300 trees a year in the rest of the city. The park has a collection of cypress, pine, oak, pepper tree, and eucalyptus grown from Sessions’ seeds imported from around the world.
