470 THE WORK OF THE STOCK EXCHANGE 
prise in America since 1830 is in itself a pragmatical tribute 
to the management as well as the work of the Exchange. An- 
other impressive tribute is likewise furnished by the steady 
growth and extension of the Exchange system to all parts of 
the country. Ill-managed and economically dangerous insti- 
tutions do not continue to grow in this way from century to 
century.
