The name itself
DOW JONES 230.07 · −30.57 · −11.73%
When a civilization needs one day to stand for an era's ending, it reaches for this one. Four days: a quarter of everything.
The day's protagonist
Sixteen million shares — no symbol.
Move: 16.4M traded — a record that stood until 1968
Volume is the protagonist because nothing else had agency left — not the bankers' pool, not the shorts, not the newspapers. The machine itself was the story: a market built for three million shares a day tried to swallow sixteen, and the ticker, the clearing apparatus, and the back offices failed together. Blocks went at whatever the market would pay; for stretches there were no bids at any price. The clerks worked past midnight for weeks clearing the paper. Behind the number: a generation of margin accounts, wiped to zero in an afternoon.
The deeper account
A brief late rally trimmed the worst of the day; the close still surrendered another ninth of everything.
The four-day sequence 305.85 → 230.07 (−25%) is the founding catastrophe of modern market memory — the reason the words "Black" and a weekday still mean what they mean.
The photograph of this day is taken after the bell, because the day itself did not end at the bell: one tower's windows stayed lit for the clerks clearing sixteen million shares of paper, and he stood in the emptied street and watched the lights. Monday's telegram had asked for funds by opening; Tuesday's statement closed the account.
The Dow would not regain its September 1929 peak until November 1954 — a quarter of a century.
This completes the 1929 trio in the encyclopedia: the warning, the abandonment, and the name.
The artifact
Monday's wire said UNANSWERED; this is what unanswered became. A generation of margin accounts went out like this — sold at the market into a day when, for stretches, there was no market, sixteen million shares through a machine built for three. The clerks worked past midnight for weeks clearing the paper. This is the last artifact in the archive's oldest chapter: the record of the day the record itself broke.

On Tuesday, October 29, 1929 — Black Tuesday — the Dow fell 11.73 percent to 230.07 on 16.4 million shares, a volume record that stood for nearly forty years. Blocks went at whatever the market would pay; for stretches there were no bids at any price, and the clearing apparatus failed together with the ticker. The four days from Thursday's warning to Tuesday's close took a quarter of everything, and the September 1929 peak was not seen again until November 1954.
