If in doubt, ask the clerk.
Having filled out the order, hand it to the clerk with the sum required, and the additional fee.
The clerk then prepares and hands out an order for the amount, on the postmaster of the town to which you are sending your letter, and this you enclose to your correspondent.
CASHING POST OFFICE ORDERS
The money order never contains the name of the sender; this the postmaster of the office from which it is sent supplies in a separate communication to the postmaster who is to pay.
No money passes from one office to the other.
A post office order is like a draft drawn by one postmaster on another. The one credits the sum, the other debits it.
The holder of an order will not get his money unless he is known to the paying postmaster or is identified.
Before paying an order the postmaster requires the holder to receipt it.
A post office money order, like a check or draft, may be transferred to another for collection.
