REGISTERING LETTERS
A letter or a parcel may be registered to further insure its safe delivery.
When a letter or parcel is registered, it must have the sender's name and address written across the left-hand end of the envelope and on the reverse side.
In addition to the stamps required ordinarily, eight cents in stamps or in a regularly prepared stamp, is the registration fee.
The clerk, receiving a registered parcel, gives the sender a receipt for the same. After the letter has reached its destination, the sender gets a second receipt, through the post office, signed with the receiver's name.
The receiver of a registered parcel signs two receipts, one for the post office and the other for the sender.
SPECIAL DELIVERY
The purpose of what is known, in connection with the post office, as the "Special Delivery System", is to insure the delivery of any letter or package to the person, to whom it is addressed, as soon as it reaches his post office.
In addition to the regular post charge, a fee of 10 cents is added for special delivery. This is in the form of a special stamp, though when this cannot be had, the same amount in ordinary stamps may be attached.
In the case noted, the sender should write in line with the stamps, "special delivery."
