  • I would imagine library holdings would be minimal on a tiny potato-shaped tropical island. I'd while away my time searching for seabeans and beautiful shells on the lovely beaches...

    I collect sea beans, a.k.a. tropical drift fruits and seeds and have contributed a substantial curated collection to a natural history museum I was once associated with....
