#Nature and classes of banks.# Banks perform a variety of useful functions in every modern community.

All these functions touch in some way upon the use of money, and banking problems always are related to money problems.

It is our purpose now to understand the general nature and work of banks in relation to the general business activity of the community.

A bank, as one first comes to know it, is a building (or a room in some building) in which there is a fire- and burglar-proof safe.

In this room are men receiving and paying out money and acting as bookkeepers.
