A half-mile stretch of beach on Terschelling island, 70 miles north of Amsterdam, was littered with bunches of unripe fruit, Buren said.

Terschelling residents are no strangers to stuff turning up on their beach; a year ago thousands of tennis shoes, aluminum briefcases and children's toys washed ashore, drawing crowds of treasure-hunting residents. Some 20 years ago it was a load of sweaters.

Plenty of beachcombers came early Wednesday for a look, said Buren, "but not as many as when we had the sneakers."
