The Stock Exchange is in the second century of its existence and in that long period of time (long relatively to the number of years during which Stock Exchanges have been known to the world) it has been forced to close its doors only twice. The first occasion was the great panic of 1873, the after effect of civil war when trading was suspended for ten days; the second came with the outbreak of the world War in the close of July, 1914. These two remarkable events differ profoundly in the gravity of the circumstances which brought them about. In 1873, although the financial disturbance was one of the greatest the United States has ever experienced, the trouble was mainly local and did not seriously involve the entire world. The Exchange was not closed in anticipation of a catastrophe but was obliged to shut down after the crash had taken place, in order to enable Wall Street to gather up its shattered fragments. The measure of this crisis was the ten days during which trading was suspended. Far different from these were the circumstances surrounding July 31st, 1914. On that eventful date a financial earthquake of a violence absolutely without precedent shook every great center of the civilized world, closing their markets one by one until New York, the last of all, finally suspended in order to forestall what would have surely been a ruinous collapse. The four and a half months during which this suspension continued stand to the ten days closing of 1873 in a proportion which fitly illustrates the relative gravity of the two historic upheavals. In the light of these facts we are justified in asserting that the events of 1914 are the most momentous that have so far constituted the life and history of the New York Stock Exchange, and consequently that some record of, and commentary upon, these facts may be of value to the present members of that body and of interest and profit to its future members.
