Project Most’s annual plant sale will be Saturday at the Neighborhood House at 92 Three Mile Harbor Road in East Hampton, from 9 a.m. to 1 p.m. There will organic vegetables seedlings, herbs, and flowers grown by its after-school students.

One can only wonder what Margaret Olivia Slocum Sage, Sag Harbor's greatest philanthropist of the early 20th century, might think of the newly emerged rift between two village institutions: the Sag Harbor School District, for which Mrs. Sage donated money to build what is now Pierson Middle and High School, and Mashashimuet Park, another one of her gifts to the people of the village.

All About Frogs and Bats

Who doesn't love frogs? Today at 4 p.m., through the East Hampton Library, the Quogue Wildlife Refuge will offer an up-close look via Zoom at Long Island frog species for children of all ages. Bats, though, might be a different story. These often-misunderstood creatures will be the subject of another library Zoom session, this one on Tuesday at 4 p.m. Sign-up information is online at easthamptonlibrary.org, or by phone at 631-324-0222, extension 2.
