A post office is a public department that provides a customer service to the public and handles their mail needs. Post offices offer mail-related services such as acceptance of parcels. In addition, many post offices offer additional services: providing and accepting government forms, processing government services and fees, banking services; the chief administrator of a post office is called a postmaster. Prior to the advent of postal and ZIP codes, postal systems would route items to a specific post office for receipt or delivery. During the nineteenth-century, in the United States, this led to smaller communities being renamed after their post offices; the term "Post-Office" has been in use since the 1650's, shortly after the legalization of private mail services in England in 1635. In early Modern England, post riders – mounted couriers – were placed every few hours along post roads at posting houses known as post houses, between major cities; these stables or inns permitted important correspondence to travel without delay.
In early America, post offices were known as "stations". This term and "post house" fell from use as horse and coach service was replaced by railways and automobiles. Today, the term "Post Office" refers to postal facilities providing customer service; the term "General Post Office" is sometimes used for the national headquarters of a postal service if it does not provide customer service within the building. A postal facility, used for processing mail is instead known as sorting office or delivery office, which may have a large central area known as a "sorting" or "postal hall". Integrated facilities combining mail processing with railway stations or airports are known as mail exchanges. There is evidence of corps of royal couriers disseminating the decrees of the Egyptian pharaohs as early as 2,400 BC and the service may precede that date. Organized systems of post houses providing swift mounted courier service seems quite ancient, although sources vary as to who initiated the practice. By the time of the Persian Empire, a system of Chapar-Khaneh existed along the Royal Road.
The 2nd-Century BC Mauryan and Han dynasties established similar systems in China. Suetonius credited Augustus with regularizing the Cursus Publicus. Local officials were obliged to provide couriers who would be responsible for their message's entire course. Locally maintained post houses owned rest houses were obliged or honored to care for them along their way. Diocletian established two parallel systems: one providing fresh horses or mules for urgent correspondence and another providing sturdy oxen for bulk shipments. Procopius, though not unbiased, records that this system remained intact until it was dismantled in the surviving empire by Justinian in the 6th Century; the Princely House of Thurn and Taxis family initiated regular mail service from Brussels in the 16th century, directing the Imperial Post of the Holy Roman Empire. The British Postal Museum claims that the oldest functioning post office in the world is on High Street in Sanquhar, Scotland; this post office has functioned continuously since 1712, an era in which horses and stage coaches were used to carry mail.
In parts of Europe, special postal censorship offices censor mail. In France, such offices were known as cabinets noirs. In many jurisdictions, mail boxes and post office boxes have long been in widespread use for drop-off and pickup of mail and small packages outside post offices or when offices are closed. Deutsche Post introduced the Pack-Station for package delivery in 2001. In the 2000s, the United States Postal Service began to install Automated Postal Centers in many locations both in post offices and in retail locations. APCs can accept mail and small packages.

Time in the United States
Time in the United States, by law, is divided into nine standard time zones covering the states and its possessions, with most of the United States observing daylight saving time for the spring and fall months. The time zone boundaries and DST observance are regulated by the Department of Transportation. Official and precise timekeeping services are provided by two federal agencies: the National Institute of Standards and Technology; the clocks run by these services are kept synchronized with each other as well as with those of other international timekeeping organizations. It is the combination of the time zone and daylight saving rules, along with the timekeeping services, which determines the legal civil time for any U. S. location at any moment. Before the adoption of four standard time zones for the continental United States, many towns and cities set their clocks to noon when the sun passed their local meridian, pre-corrected for the equation of time on the date of observation, to form local mean solar time.
Noon occurred at different times but time differences between distant locations were noticeable prior to the 19th century because of long travel times and the lack of long-distance instant communications prior to the development of the telegraph. The use of local solar time became awkward as railways and telecommunications improved. American railroads maintained many different time zones during the late 1800s; each train station set its own clock making it difficult to coordinate train schedules and confusing passengers. Time calculation became a serious problem for people traveling by train, according to the Library of Congress; every city in the United States used a different time standard so there were more than 300 local sun times to choose from. Time zones were therefore a compromise, relaxing the complex geographic dependence while still allowing local time to be approximate with mean solar time. Railroad managers tried to address the problem by establishing 100 railroad time zones, but this was only a partial solution to the problem.
Weather service chief Cleveland Abbe had needed to introduce four standard time zones for his weather stations, an idea which he offered to the railroads. Operators of the new railroad lines needed a new time plan that would offer a uniform train schedule for departures and arrivals. Four standard time zones for the continental United States were introduced at noon on November 18, 1883, when the telegraph lines transmitted time signals to all major cities. In October 1884, the International Meridian Conference at Washington DC adopted a proposal which stated that the prime meridian for longitude and timekeeping should be one that passes through the centre of the transit instrument at the Greenwich Observatory in the United Kingdom; the conference therefore established the Greenwich Meridian as the prime meridian and Greenwich Mean Time as the world's time standard. The US time-zone system grew from this, in which all zones referred back to GMT on the prime meridian. In 1960, the International Radio Consultative Committee formalized the concept of Coordinated Universal Time, which became the new international civil time standard.
UTC is, within about 1 second, mean solar time at 0°. UTC does not observe daylight saving time. For most purposes, UTC is considered interchangeable with GMT, but GMT is no longer defined by the scientific community. UTC is one of several related successors to GMT. Standard time zones in the United States are defined at the federal level by law 15 USC §260; the federal law establishes the transition dates and times at which daylight saving time occurs, if observed. It is the authority of the Secretary of Transportation, in coordination with the states, to determine which regions will observe which of the standard time zones and if they will observe daylight saving time; as of August 9, 2007, the standard time zones are defined in terms of hourly offsets from UTC. Prior to this they were based upon the mean solar time at several meridians 15° apart west of Greenwich. Only the full-time zone names listed below are official. View the standard time zone boundaries here; the United States uses nine standard time zones.
As defined by US law they are: From east to west, the four time zones of the contiguous United States are: Eastern Time Zone, which comprises the states on the Atlantic coast and the eastern two thirds of the Ohio Valley. Central Time Zone, which comprises the Gulf Coast, Mississippi Valley, most of the Great Plains. Mountain Time Zone, which comprises the states and portions of states that include the Rocky Mountains and the western quarter of the Great Plains. Pacific Time Zone, which comprises the states on the Pacific coast, plus Nevada and the Idaho panhandle. Alaska Time Zone, which comprises most of the state of Alaska. Hawaii-Aleutian Time Zone, which includes Hawaii and most of the length of the Aleutian Islands chain. Samoa Time Zone, which comprises American Samoa. Chamorro Time Zone, which comprises Guam and the Northern Mariana Islands. Atlantic Time Zone, which comprises Puerto Rico and the US Virgin Islands; some United States Minor Outlying Islands are outside the time zones defined by 15 U.

Texas is the second largest state in the United States by both area and population. Geographically located in the South Central region of the country, Texas shares borders with the U. S. states of Louisiana to the east, Arkansas to the northeast, Oklahoma to the north, New Mexico to the west, the Mexican states of Chihuahua, Nuevo León, Tamaulipas to the southwest, while the Gulf of Mexico is to the southeast. Houston is the most populous city in Texas and the fourth largest in the U. S. while San Antonio is the second-most populous in the state and seventh largest in the U. S. Dallas–Fort Worth and Greater Houston are the fourth and fifth largest metropolitan statistical areas in the country, respectively. Other major cities include Austin, the second-most populous state capital in the U. S. and El Paso. Texas is nicknamed "The Lone Star State" to signify its former status as an independent republic, as a reminder of the state's struggle for independence from Mexico; the "Lone Star" can be found on the Texan state seal.
The origin of Texas's name is from the word taysha. Due to its size and geologic features such as the Balcones Fault, Texas contains diverse landscapes common to both the U. S. Southern and Southwestern regions. Although Texas is popularly associated with the U. S. southwestern deserts, less than 10% of Texas's land area is desert. Most of the population centers are in areas of former prairies, grasslands and the coastline. Traveling from east to west, one can observe terrain that ranges from coastal swamps and piney woods, to rolling plains and rugged hills, the desert and mountains of the Big Bend; the term "six flags over Texas" refers to several nations. Spain was the first European country to claim the area of Texas. France held a short-lived colony. Mexico controlled the territory until 1836 when Texas won its independence, becoming an independent Republic. In 1845, Texas joined the union as the 28th state; the state's annexation set off a chain of events that led to the Mexican–American War in 1846.
A slave state before the American Civil War, Texas declared its secession from the U. S. in early 1861, joined the Confederate States of America on March 2nd of the same year. After the Civil War and the restoration of its representation in the federal government, Texas entered a long period of economic stagnation. Four major industries shaped the Texas economy prior to World War II: cattle and bison, cotton and oil. Before and after the U. S. Civil War the cattle industry, which Texas came to dominate, was a major economic driver for the state, thus creating the traditional image of the Texas cowboy. In the 19th century cotton and lumber grew to be major industries as the cattle industry became less lucrative, it was though, the discovery of major petroleum deposits that initiated an economic boom which became the driving force behind the economy for much of the 20th century. With strong investments in universities, Texas developed a diversified economy and high tech industry in the mid-20th century.
As of 2015, it is second on the list of the most Fortune 500 companies with 54. With a growing base of industry, the state leads in many industries, including agriculture, energy and electronics, biomedical sciences. Texas has led the U. S. in state export revenue since 2002, has the second-highest gross state product. If Texas were a sovereign state, it would be the 10th largest economy in the world; the name Texas, based on the Caddo word táyshaʼ "friend", was applied, in the spelling Tejas or Texas, by the Spanish to the Caddo themselves the Hasinai Confederacy, the final -s representing the Spanish plural. The Mission San Francisco de los Tejas was completed near the Hasinai village of Nabedaches in May 1690, in what is now Houston County, East Texas. During Spanish colonial rule, in the 18th century, the area was known as Nuevo Reino de Filipinas "New Kingdom of the Philippines", or as provincia de los Tejas "province of the Tejas" also provincia de Texas, "province of Texas", it was incorporated as provincia de Texas into the Mexican Empire in 1821, declared a republic in 1836.
The Royal Spanish Academy recognizes both spellings and Texas, as Spanish-language forms of the name of the U. S. State of Texas; the English pronunciation with /ks/ is unetymological, based in the value of the letter x in historical Spanish orthography. Alternative etymologies of the name advanced in the late 19th century connected the Spanish teja "rooftile", the plural tejas being used to designate indigenous Pueblo settlements. A 1760s map by Jacques-Nicolas Bellin shows a village named Teijas on Trinity River, close to the site of modern Crockett. Texas is the second-largest U. S. state, with an area of 268,820 square miles. Though 10% larger than France and twice as large as Germany or Japan, it ranks only 27th worldwide amongst country subdivisions by size. If it were an independent country, Texas would be the 40th largest behind Zambia. Texas is in the south central part of the United States of America. Three of its borders are defined by rivers; the Rio Grande forms a natural border with the Mexican states of Chihuahua, Nuevo León, Tamaulipas to the south.
The Red River forms a natural border with Arkansas to the north. The Sabine River forms a natural border with Louisiana to the east; the Texas Panhandle has an eastern border with Oklahoma at 100° W, a northern border with Oklahoma at 36°30' N and a western

Muenster is a German Catholic city in western Cooke County, United States, along U. S. Route 82; the population was 1,544 at the 2010 census. In 1887, the Missouri–Kansas–Texas Railroad constructed a line from Gainesville to Henrietta that passed through the site that would become Muenster; the town was subsequently founded in 1889 by German Catholic settlers Carl and Emil Flusche, who invited other German Catholics to join them. The town was to be called "Westphalia", but since the name Westphalia, was taken, Muenster was selected instead in honor of Münster, the capital of Westphalia, but these cities are not sister-cities. Many residents still spoke German in day-to-day life up until the First World War, after which the language was no longer taught in the schools and declined in use. With more than 90% of the population German and Catholic, the city has preserved many German customs, still produces traditional foods at the local meat market and Bäckerei. An annual festival in April, includes beer, BBQ, German food and bike and footraces.
A Christkindlmarkt is held each year on Thanksgiving weekend. Catholicism was so important to the early settlers that they built a school before a church was established; that school, Sacred Heart Catholic School, still exists today, along with the public Muenster Independent School District. Muenster is located in western Cooke County at 33°39′03″N 97°22′32″W. According to the United States Census Bureau, the city has a total area of 2.5 square miles, of which 2.3 acres, or 0.14%, is covered by water. As of the census of 2000, 1,556 people, 588 households, 401 families resided in the city; the population density was 1,209.3 people per square mile. The 628 housing units averaged 488.1 per square mile. The racial makeup of the city was 97.62% White, 0.13% Native American, 0.51% Asian, 0.71% from other races, 1.03% from two or more races. About 2.19% of the population was Hispanic or Latino of any race.

In the city, the population was distributed as 29.5% under the age of 18, 6.0% from 18 to 24, 26.9% from 25 to 44, 18.3% from 45 to 64, 19.3% who were 65 years of age or older. The median age was 37 years. For every 100 females, there were 88.1 males. For every 100 females age 18 and over, there were 83.8 males. The median income for a household in the city was $39,125, for a family was $48,000. Males had a median income of $29,688 versus $22,697 for females; the per capita income for the city was $20,638. About 4.3% of families and 5.4% of the population were below the poverty line, including 5.7% of those under age 18 and 8.1% of those age 65 or over. Augustine Danglmayr, Auxiliary Bishop of the Roman Catholic Diocese of Dallas, was born in Muenster; the climate in this area is characterized by hot, humid summers and mild to cool winters.
According to the Köppen climate classification system, Muenster has a humid subtropical climate, Cfa on climate maps. City of Muenster official website Muenster from the Handbook of Texas Online
2010 United States Census
The 2010 United States Census is the twenty-third and most recent United States national census. National Census Day, the reference day used for the census, was April 1, 2010; the census was taken via mail-in citizen self-reporting, with enumerators serving to spot-check randomly selected neighborhoods and communities. As part of a drive to increase the count's accuracy, 635,000 temporary enumerators were hired; the population of the United States was counted as 308,745,538, a 9.7% increase from the 2000 Census. This was the first census in which all states recorded a population of over half a million, as well as the first in which all 100 largest cities recorded populations of over 200,000; as required by the United States Constitution, the U. S. census has been conducted every 10 years since 1790. The 2000 U. S. Census was the previous census completed. Participation in the U. S. Census is required by law in Title 13 of the United States Code. On January 25, 2010, Census Bureau Director Robert Groves inaugurated the 2010 Census enumeration by counting World War II veteran Clifton Jackson, a resident of Noorvik, Alaska.
More than 120 million census forms were delivered by the U. S. Post Office beginning March 15, 2010; the number of forms mailed out or hand-delivered by the Census Bureau was 134 million on April 1, 2010. Although the questionnaire used April 1, 2010 as the reference date as to where a person was living, an insert dated March 15, 2010 included the following printed in bold type: "Please complete and mail back the enclosed census form today." The 2010 Census national mail participation rate was 74%. From April through July 2010, census takers visited households that did not return a form, an operation called "non-response follow-up". In December 2010, the U. S. Census Bureau delivered population information to the U. S. President for apportionment, in March 2011, complete redistricting data was delivered to states. Identifiable information will be available in 2082; the Census Bureau did not use a long form for the 2010 Census. In several previous censuses, one in six households received this long form, which asked for detailed social and economic information.
The 2010 Census used only a short form asking ten basic questions: How many people were living or staying in this house, apartment, or mobile home on April 1, 2010? Were there any additional people staying here on April 1, 2010 that you did not include in Question 1? Mark all that apply: Is this house, apartment, or mobile home – What is your telephone number? What is Person 1's name? What is Person 1's sex? What is Person 1's age and Person 1's date of birth? Is Person 1 of Hispanic, Latino, or Spanish origin? What is Person 1's race? Does Person 1 sometimes live or stay somewhere else? The form included space to repeat all of these questions for up to twelve residents total. In contrast to the 2000 census, an Internet response option was not offered, nor was the form available for download. Detailed socioeconomic information collected during past censuses will continue to be collected through the American Community Survey; the survey provides data about communities in the United States on a 1-year or 3-year cycle, depending on the size of the community, rather than once every 10 years.
A small percentage of the population on a rotating basis will receive the survey each year, no household will receive it more than once every five years. In June 2009, the U. S. Census Bureau announced. However, the final form did not contain a separate "same-sex married couple" option; when noting the relationship between household members, same-sex couples who are married could mark their spouses as being "Husband or wife", the same response given by opposite-sex married couples. An "unmarried partner" option was available for couples; the 2010 census cost $13 billion $42 per capita. Operational costs were $5.4 billion under the $7 billion budget. In December 2010 the Government Accountability Office noted that the cost of conducting the census has doubled each decade since 1970. In a detailed 2004 report to Congress, the GAO called on the Census Bureau to address cost and design issues, at that time, had estimated the 2010 Census cost to be $11 billion. In August 2010, Commerce Secretary Gary Locke announced that the census operational costs came in under budget.
Locke credited the management practices of Census Bureau director Robert Groves, citing in particular the decision to buy additional advertising in locations where responses lagged, which improved the overall response rate. The agency has begun to rely more on questioning neighbors or other reliable third parties when a person could not be reached at home, which reduced the cost of follow-up visits.

A mural is any piece of artwork painted or applied directly on a wall, ceiling or other permanent surface. A distinguishing characteristic of mural painting is that the architectural elements of the given space are harmoniously incorporated into the picture; some wall paintings are painted on large canvases, which are attached to the wall. Whether these works can be called "murals" is a subject of some controversy in the art world, but the technique has been in common use since the late 19th century. Murals of sorts date to Upper Paleolithic times such as the cave paintings in the Lubang Jeriji Saléh cave in Borneo, Chauvet Cave in Ardèche department of southern France. Many ancient murals have been found within ancient Egyptian tombs, the Minoan palaces, the Oxtotitlán cave and Juxtlahuaca in Mexico and in Pompeii. During the Middle Ages murals were executed on dry plaster; the huge collection of Kerala mural painting dating from the 14th century are examples of fresco secco. In Italy, circa 1300, the technique of painting of frescos on wet plaster was reintroduced and led to a significant increase in the quality of mural painting.
In modern times, the term became more well-known with the Mexican muralism art movement. There are many different techniques; the best-known is fresco, which uses water-soluble paints with a damp lime wash, a rapid use of the resulting mixture over a large surface, in parts. The colors lighten; the marouflage method has been used for millennia. Murals today are painted in a variety of ways; the styles can vary from abstract to trompe-l'œil. Initiated by the works of mural artists like Graham Rust or Rainer Maria Latzke in the 1980s, trompe-l'oeil painting has experienced a renaissance in private and public buildings in Europe. Today, the beauty of a wall mural has become much more available with a technique whereby a painting or photographic image is transferred to poster paper or canvas, pasted to a wall surface to give the effect of either a hand-painted mural or realistic scene. In the history of mural several methods have been used: A fresco painting, from the Italian word affresco which derives from the adjective fresco, describes a method in which the paint is applied on plaster on walls or ceilings.
The buon fresco technique consists of painting in pigment mixed with water on a thin layer of wet, lime mortar or plaster. The pigment is absorbed by the wet plaster. After this the painting stays for a long time up to centuries in brilliant colors. Fresco-secco painting is done on dry plaster; the pigments thus require a binding medium, such as egg, glue or oil to attach the pigment to the wall. Mezzo-fresco is painted on nearly-dry plaster, was defined by the sixteenth-century author Ignazio Pozzo as "firm enough not to take a thumb-print" so that the pigment only penetrates into the plaster. By the end of the sixteenth century this had displaced the buon fresco method, was used by painters such as Gianbattista Tiepolo or Michelangelo; this technique had, in reduced form, the advantages of a secco work. In Greco-Roman times encaustic colors applied in a cold state were used. Tempera painting is one of the oldest known methods in mural painting. In tempera, the pigments are bound in an albuminous medium such as egg yolk or egg white diluted in water.
In 16th-century Europe, oil painting on canvas arose as an easier method for mural painting. The advantage was that the artwork could be completed in the artist's studio and transported to its destination and there attached to the wall or ceiling. Oil paint may be a less satisfactory medium for murals because of its lack of brilliance in colour; the pigments are yellowed by the binder or are more affected by atmospheric conditions. The canvas itself is more subject to rapid deterioration than a plaster ground. Different muralists tend to become experts in their preferred medium and application, whether that be oil paints, emulsion or acrylic paints applied by brush, roller or airbrush/aerosols. Clients will ask for a particular style and the artist may adjust to the appropriate technique. A consultation leads to a detailed design and layout of the proposed mural with a price quote that the client approves before the muralist starts on the work; the area to be painted can be gridded to match the design allowing the image to be scaled step by step.
In some cases the design is projected straight onto the wall and traced with pencil before painting begins. Some muralists will paint directly without any prior sketching, preferring the spontaneous technique. Once completed the mural can be given coats of varnish or protective acrylic glaze to protect the work from UV rays and surface damage. In modern, quick form of muralling, young enthusiasts use POP clay mixed with glue or bond to give desired models on a canvas board; the canvas is set aside to let the clay dry. Once dried, the canvas and the shape can be painted with your choice of colors and coated with varnish; as an alternative to a hand-painted or airbrushed mural, digitally printed murals can be applied to surfaces. Existing murals can be photographed and be reproduced
