The Money at the Bottom of the Sea

In a story published in 1910, a limestone disc lost at sea still counts as a family’s wealth.

In a story published by William Henry Furness III in 1910, a fortune lies under a few hundred feet of water, unseen by the people who recognise its value. The story describes a disc of limestone with a hole through the middle for a carrying pole. Its size, wrote the American traveller William Henry Furness III in 1910, "is known only by tradition." For two or three generations it had belonged to one family, and nobody on the island thought its being underwater was a reason it should stop.

Stone from another island

The Yapese call these discs rai; Furness wrote down the word he heard as fei. The stone used for these discs was not available on Yap, so the discs were quarried on Palau, several hundred miles to the southwest, and brought home by canoe and on rafts. They run from a few inches across to about twelve feet, and the biggest weigh several tonnes. Value depended on size and on the fineness of the stone, but above all on history: who had owned it, what it had cost to fetch, whether men had died on the voyage.

Because the large ones were impractical to move, they mostly weren't. A sale was made by agreement. The buyer, Furness wrote, was "quite content to accept the bare acknowledgment of ownership," and the stone stayed where it was, often on the former owner's land. The ledger was the village's memory.

That is how the family with the sunken stone stayed rich. Their ancestor, Furness was told, had been towing it home on a raft when a violent storm forced the crew to cut it loose. They came home, testified to its size and quality, and swore the loss was no fault of the owner. The island agreed that a few hundred feet of water did not change the matter. Furness heard this from his Yapese friend Fatumak; it is oral tradition, set down once by a visitor, rather than a surveyed underwater find.

Inflation

The record also has its inflation. David Dean O'Keefe, an Irish-American trader, began sending a schooner to Palau with Yapese stonecutters and bringing back stones to trade for copra and sea cucumber. By later accounts, Yapese valued O'Keefe's stones below the old ones carried by canoe. They had come too easily.

The story has since travelled beyond Yap. Economists have used the stones to ask what gives money its value: the material itself, the work invested in acquiring it, or an agreement that ownership will be recognised. The account of a lost stone makes that question unusually concrete.

Still happening

Dollars handle ordinary purchases, while rai retain roles in customary transactions. Many stand along village paths and meeting grounds. Their ownership is publicly known, which makes an unnoticed transfer quite different from pocketing a coin. They still occasionally change hands in customary exchange, for land and for marriages, and the transfer is still a matter of everyone knowing.

In Furness’s account, the stone under the sea remained wealth because its ownership was recognised. The lesson concerns an agreement, not the verified whereabouts of a stone today. A bank balance asks us to recognise something similarly abstract.

Notes & Sources

  1. The Island of Stone Money: Uap of the Carolines (1910). William Henry Furness III, via Project Gutenberg. Supports the sunken-stone story as told by Fatumak (raft cut adrift in a storm, crew's testimony, "a few hundred feet of water," size "known only by tradition"), the word fei, quarrying on Palau and transport by canoe and raft, sizes up to twelve feet, the "bare acknowledgment of ownership" quote, and an unnamed Irish-American trader's schooner trade in stones for copra and bêche-de-mer.
  2. Rai stones. Wikipedia. Supports quarrying mainly on Palau, sizes up to 3.6 metres and about 4 tonnes, value tied to history and deaths in transport, transfer by oral record without moving the stone, David Dean O'Keefe's role and the copra and trepang trade, Friedman's economic use of the stones, and continued use in marriage and inheritance at meeting houses and along paths.
  3. Cash, Card, or Car-Sized Stone: Payment Options on the Island of Yap. Atlas Obscura, via Slate. Supports the Palau quarries, sizes from a few inches to twelve feet, the central carrying hole, O'Keefe's stones being valued below traditionally made ones, a circulating rai lying on the sea floor, transfer by acknowledgement alone, and the US dollar as the everyday currency alongside rai.
  4. Stone money of Yap. National Bank of Belgium Museum. Supports the stone being absent from Yap and brought from Palau on rafts towed by canoe, the largest stones weighing several tonnes, value rising with the risks and deaths of the voyage, ownership changing without the stone moving, and stones still occasionally paying for land.
  5. The Island of Stone Money (Milton Friedman, Hoover Institution working paper, 1991). Habele Institute. Supports the claim that economists have used the stones to ask what gives money its value, via the citation and abstract of Friedman's 1991 paper comparing Yap to gold earmarked at the New York Federal Reserve.
  6. Rai: big money. Bank of Canada Museum. Supports quarrying on Palau, canoes towing rafts, value growing with a stone's history, ownership reassigned by public assent without moving the stone, the legend of a rai lost at sea that still functioned as money, and O'Keefe's stones being worth less on Yap than older ones.
