“Beekeepers Wallace Anderson and R.R. Talbert tending to tupelo honey beehives in Apalachicola, Florida,” May 6, 1948, via Florida Memory (State Library and Archives of Florida) Commons on flickr.
Another note on the Archive’s website says, “Typical scaffold, platform 14 to 16 feet high and 300 to 700 feet long on which colonies (hives) are placed.”

An amazing scene! You can rarely find tupelo honey up north, though I do remember having it in Rochester. I made a big effort to find it in honor of Van Morrison’s song of that name.
🙂 This photo actually reminded me of Rwanda. Beekeepers would put basket hives up in the eucalyptus trees lining the main highway to the northwest. (But they didn’t build a walkway between the trees; the younger men would shimmy up the trunks.)
