THE COMMISSION HOUSE 
inaugurated in 1881, and with San Francisco in 1901. Since 
that date the wire systems of several large Stock Exchange 
commission houses have crossed the border to various Cana- 
dian cities. One Wall Street firm has even installed a private 
wire by cable to Havana, Cuba. Stock Exchange firms also 
have established branch offices or affiliated companies in the 
leading centers of Europe. And when the steady growth of 
the Stock Exchange as an international market and credit 
center is realized, it seems patent that the future may witness 
the extra-national extension of the wire systems of many Stock 
Exchange houses. 
At first considerable prejudice was shown against the new 
“wire house.” It was thought that no firm could properly 
control its business over such distances. There was even a 
tendency to discriminate against the loans made by such houses, 
because of the supposed unreliability of the business. If any- 
thing, just the opposite attitude is taken today, for, other 
factors apart, the wire house represents a diversification of 
business risk over many parts of the country.

The Wire Systems of Today.—Speaking of the extensive 
modern use of private wire systems by financial and commer- 
cial firms, a leading New York financial publication® has 
stated * 
Now there are about a thousand private wires in operation, tapping 
every city or locality of any importance in the United States and 
Canada. It is estimated that they are more than 500,000 miles in 
length, and represent a yearly expenditure of more than $1 5,000,000, 
to which must of course be added the wages of the operators who 
man them and the other expenses for which their lessees are liable. 
It is therefore probable that the private wire system of America 
costs more than twenty million dollars a year, and perhaps the total 
is a great deal higher . . . 
Between New York and Chicago it is estimated that there are 100 
leased wires; eight between Chicago and the Pacific coast; 100 between 
New York and Boston: 75 between New York and Philadelphia, 
Baltimore and Washington: 10 between New York and points south
