These small floats have been recovered from the Aleutian Islands and the Alaskan coast.
Original blown glass net floats once used on drift nets, principally in the Pacific from about 1910 on. Most are Japanese or Korean, but they were also used by the Chinese, Russians and some Pacific Islanders.
When I was a boy I remember seeing a few on the docks in Halifax. The Norwegians, Portuguese and Spaniards occasionally used them in the Atlantic in the 1950s. As with so much else, the glass float has given way to plastic.
These small floats have been recovered from the Aleutian Islands and the Alaskan coast. They have floated on the Japan current and have sat buried in the sand sometimes for many years. Some are sand-marked and show the impression of the net that once enclosed them. A few still have their original hand-knotted net in place.
