This is in compliance with law.

Depositors, posted as to the law, open another account with
another bank, and keep on till the interest limit is reached.

HOW TO DRAW MONEY

A savings bank depositor may either draw money himself or through
some properly authorized person.

This is the method:

The deposit book is presented to the paying teller. The owner
states the sum he wants to draw.

Having assured himself that the bearer of the book is the right
person, the teller takes a receipt in a book kept for the purpose,
for the amount, enters the same on the right hand or debit side of
the book, and hands out the money.

There is a form of authorization for another to draw, printed on
the deposit book. This must be copied and its directions complied
with.

Most banks will not allow depositors to draw out less than a fixed
sum, say $5.00.

This saves trouble, and prevents thoughtless depositors from going
to the bank every time they want a dollar.
