So far we have only considered what happens to the money of those who
save as long as it is left in the hands of their bankers, and we have
seen that it is only likely to be employed internationally, if invested
by bankers in bills of exchange which form a comparatively small part of
their assets. It is true that bankers also invest money in securities,
and that some of these are foreign, but here again the proportion
invested abroad is so small that we may be reasonably sure that any
money left by us in the hands of our bankers will be employed at home.

But in actual practice those who save do not pile up a large balance at
their banks. They keep what is called a current account, consisting of
amounts paid in in cash or in cheques on other banks or their own bank,
and against this account they draw what is needed for their weekly and
monthly payments; sometimes, also, they keep a certain amount on deposit
account, that is an account on which they can only draw after giving a
week's notice or more. On their deposit account they receive interest,
on their current account they may in some parts of the country receive
interest on the average balance kept. But the deposit account is most
often kept by people who have to have a reserve of cash quickly
available for business purposes. The ordinary private investor, when he
has got a balance at his bank big enough to make him feel comfortable
about being able to meet all probable outgoings, puts any money that he
may have to spare into some security dealt in on the Stock Exchange, and
so securities and the Stock Exchange have to be described and examined
next. They are very much to the point, because it is through them that
international finance has done most of its work.

Securities, then, are the stocks, shares and bonds which are given to
those who put money into companies, or into loans issued by
