the postal dog
On an autumn day in 1888, a shaggy pup took his first steps toward becoming a postal legend when he crept into the Albany, NY, Post Office. Postal employees allowed him to stay and named him Owney.
At first, Owney stayed close to the Post Office, but he soon began riding mail wagons to the train depot and the railway mail car down to New York City and back to Albany. As Owney traveled farther, his friends at the Albany Post Office feared he might wander too far away to find his way home again, so they purchased a leather collar with a tag reading “Owney, Post Office, Albany, N.Y.” Railway mail clerks recorded Owney’s travels by attaching metal baggage tags to his collar to identify the rail lines he traveled on. He was soon so weighed down by his collection of tags that Postmaster General John Wanamaker presented Owney with a jacket to distribute their weight more evenly.
Owney took to traveling farther and staying away longer, eventually visiting Mexico, Canada, Japan, China, Singapore, Suez, Algiers and the Azores.
One day, while being shown off to an Ohio newspaper reporter, Owney bit the clerk who was handling him. The postmaster had Owney put down on June 11, 1897. Railway mail clerks chipped in money to have a taxidermist preserve Owney’s body, which then was sent to postal headquarters in Washington, DC, for exhibit. In 1911, the Post Office Department entrusted Owney to the Smithsonian Institution. Since 1993, Owney has been on display at the National Postal Museum in Washington, DC. In 2011, Owney was honored on a commemorative U.S. postage stamp.

LINCOLN
On May 7, 1833, 24-year-old Abraham Lincoln was appointed postmaster of New Salem, IL. Lincoln served until the office was closed May 30, 1836.
Two postmasters became U.S. presidents later in their careers — Abraham Lincoln and Harry Truman. Truman held the title and signed papers but immediately turned the position and its pay over to an assistant. Lincoln was the only president who served as a postmaster.
On May 7, 1833, 24-year-old Lincoln was appointed Postmaster of New Salem, IL. Lincoln served until the office was closed May 30, 1836. Postal records show that Lincoln earned $55.70 as postmaster in fiscal year 1835 and $19.48 for one quarter’s work in fiscal year 1837. Besides his pay, Lincoln, as postmaster, could send and receive personal letters free and get one daily newspaper delivered free. Mail arrived once a week. If an addressee did not collect the mail, as was the custom, Lincoln delivered it personally — usually carrying the mail in his hat. Even then, Lincoln was “Honest Abe.”
Reportedly, when the New Salem Post Office was discontinued, Lincoln had a balance of $16 or $18, which he took with him to Springfield, IL. Months later, while his close friend Dr. A. G. Henry was visiting, a Post Office agent called on Lincoln to collect the funds. Henry knew that Lincoln had been in financial straits and feared that he might not have the money. Henry recalled that just as he was about to offer Lincoln a loan, the future president “. . . went over to his trunk at his boarding house, and returned with an old blue sock with a quantity of silver and copper coin tied up in it. Untying the sock, he poured the contents on the table and proceeded to count the coin, which consisted of such silver and copper pieces as the country-people were then in the habit of using in paying postage. On counting it up there was found the exact amount, to a cent, of the draft, and in the identical coin which had been received. He never used, under any circumstances, trust funds.”

National Postal Museum opens
In 1993, the Smithsonian's National Postal Museum opened. This museum is dedicated to the preservation, study and presentation of postal history and philately.
The Smithsonian’s National Postal Museum offers exhibits tracing the history of the postal system in the United States. It houses millions of postal-related items — mostly stamps, but also postal stationery, greeting cards, covers and letters, mailboxes, postal vehicles, handstamps, metering machines, patent models, uniforms, badges and other objects related to postal history and philately. The museum’s library, with more than 40,000 volumes and manuscripts, is open to the public by appointment. In 2013, the William H. Gross Stamp Gallery — the largest in the world — opened at the museum.

first Post Office
The first Post Office in the American colonies was established in a Boston tavern in 1639.
and the U.S. Mail
Extra! Extra! American newspapers largely owe their existence to Post Offices. As part of the Post Office Act of 1792, newspapers were permitted to be mailed at extremely low rates. By the start of the 19th century, newspapers made up the bulk of the U.S. Mail.
delivered by mail
The farm-to-table concept isn’t new. From 1914 to 1920, the farm-to-table program was a novel initiative that allowed farmers to arrange prices with people in urban areas and then mail them fresh meats, eggs, dairy products, produce, honey, jelly and more. This was a way to give farmers more customers and city dwellers greater and cheaper access to fresh goods.
JUST NUTS!
Coconuts can be mailed without a box. Simply address the coconut and add your return addresses on the husk, have it weighed for appropriate postage, and it is shipped as-is. Photo: Coconuts ready for mailing at the Molokai, HI, Post Office.

potatoes in the mail
It's SPUDTACULAR! As with coconuts, potatoes can be mailed without a box. Simply write the address it's going to and your return addresses on the spud, have it weighed for appropriate postage, and it can be shipped as-is. Let someone know they are special. Send a tater!

in the mail
Hope in the mail. In 1958, luxury jeweler Harry Winston donated the Hope Diamond to the Smithsonian Institution. With his years of experience in shipping jewelry all over the world, Winston sent the diamond via Registered Mail service with the Post Office Department.

The diamond was placed in a box, wrapped in brown paper, and sent by registered mail from New York in a Railway Post Office train car. In Washington, DC, it was picked up by a mail carrier and driven to the National Museum of Natural History. The price paid for shipping the gem, valued at $1 million at the time, was $145.29, most of that for package insurance.
gold in the mail
Under the watchful security of the Postal Inspection Service, Railway Mail Service clerks transferred some of the $9 billion in gold bullion shipped as Registered Mail from the New York City Assay Office to the depository at Fort Knox, KY, in 1941.
The Inspection Service provided security and management in the cooperative effort between the Post Office Department, local law enforcement, U.S. Army and U.S. Treasury Department.
in the mail??
Do not try to ship your kids! In the early days of Parcel Post service, a few parents managed to mail their children to relatives. In 1913, an 8-month-old baby in Ohio was mailed by his parents to his grandmother, who lived a few miles away. The baby was safely delivered! Regulations were quickly established to prevent any additional mailing of children through the U.S. Mail.

BRICK IN THE MAIL
Individual bricks can be shipped in the U.S. Mail. Get a permanent marker, write the address and your return address, get it weighed and add the postage. Send that special someone a brick of affection.
Just don’t think you can send enough bricks to build a house or, perhaps a bank. Been there. Done that. You can read about the bank of Vernal, UT, here.

PO made of straw
In Corrales, NM, in 1999, a new Post Office was built with more than 900 bales of straw as insulation. The Post Office is still standing strong and saving energy — a proud testament to the Postal Service’s longstanding history of sustainable practices.


Corrales NM Post Office
Flies Here
No high-flying flag here. The B. Free Franklin Post Office in Philadelphia, which is part of Independence National Historical Park, does not fly the U.S. flag. This office aims to recreate the atmosphere of a colonial-era Post Office, and the Stars and Stripes did not yet exist in 1775.
Franklin used to own the building and there is a small museum on the second floor.

historic buildings
More than 1,400 USPS-owned buildings are listed on the National Register of Historic Places.
Our History is the History of America
Many Postal Service buildings are historical properties. At many Post Office locations, you’ll find impressive works
of art that reflect the stories of our people and our nation.

that motto
The U.S. Postal Service has no official motto. Nope, it’s not this phrase: “Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds.” But we certainly appreciate the sentiment.
About that motto…
Those words are engraved on the front of the James A. Farley Post Office in New York City, set in stone by the architectural firm that built it. The phrase is taken from an ancient book by the Greek historian Herodotus and refers to messengers in the Persian Empire.
The phrase comes from book 8, paragraph 98, of The Persian Wars by Herodotus, a Greek historian. During the wars between the Greeks and Persians (500-449 B.C.), the Persians operated a system of mounted postal couriers who served with great fidelity.
The popular belief that Herodotus’s description of the Persian postal service is about the U.S. Postal Service is a tribute to the hundreds of thousands of men and women who have delivered the mail reliably and dependably, through all conditions, for centuries.

postmaster general
The Postal Service traces its origin to 1775, when Benjamin Franklin was appointed as the first postmaster general of the United Colonies. His annual salary was $1,000. From 1872 to 1971, the postmaster general was a presidential Cabinet member.
delivery
The most unusual mode of delivery used by the Postal Service is the mule train. Since the 1930s, mules have been carrying mail and goods to the Havasupai people inside the Grand Canyon.

Pony Express
The official name for the Pony Express was the Central Overland California & Pike’s Peak Express Co. Before they were hired, riders had to swear on a Bible not to curse, fight or abuse their animals. The service was in operation only from April 3, 1860, to Oct. 26, 1861. It was never part of the U.S. Postal Service but operated as a contract U.S. Mail route during its final months.
That’s no pony, that’s a big horse
The official name for the “Pony Express” was the Central Overland California & Pike’s Peak Express Co. Before they were hired, riders had to swear on a Bible not to curse, fight or abuse their animals. The service was in operation only from April 3, 1860, to Oct. 26, 1861. It operated as a U.S. Mail route during its final 4 months.
On April 3, 1860, the first Pony Express mail, traveling by horse and rider relay teams, simultaneously leaves St. Joseph, MO, and Sacramento, CA. Ten days later, on April 13, the westbound rider and mail packet completed the 1,800-mile journey and arrived in Sacramento, beating the eastbound packet’s arrival in St. Joseph by two days and setting a new standard for speedy mail delivery. The Pony Express was by far the most effective way to communicate cross-country —until the telegraph came along. After 18 months in operation, the system was shuttered on October 26, 1861, and the last remaining mail was delivered.
The Pony Express National Historic Trail was designated to preserve the story and routes of this nationally significant trail and to support the associated sites that preserve its history. Learn more at https://www.nps.gov/poex
