Borax
–
Soid Borax, also known as sodium borate, sodium tetraborate, or disodium tetraborate, is an important boron compound, a mineral, and a salt of boric acid. Powdered borax is white, consisting of colorless crystals that dissolve easily in water. Borax has a variety of uses. It is a component of many detergents, cosmetics, and enamel glazes, in artisanal gold mining, the borax method is sometimes used as a substitute for toxic mercury in the gold extraction process. Borax was reportedly used by miners in parts of the Philippines in the 1900s. The term borax is used for a number of closely related minerals or chemical compounds that differ in their water content. Commercially sold borax is partially dehydrated, Borax was first discovered in dry lake beds in Tibet and was imported via the Silk Road to the Arabian Peninsula in the 8th Century AD. However, it is formulated as Na2·8H2O, since borax contains the 2− ion. In this structure, there are two four-coordinate boron atoms and two boron atoms. Borax is also converted to boric acid and other borates. When borax is added to a flame, it produces a green color. Borax is not used for purpose in fireworks due to the overwhelming yellow color of sodium. Boric acid is used to color methanol flames a transparent green, the English word borax is Latinized, the Middle English form was boras, from Old French boras, bourras. That may have been from medieval Latin baurach, borac, borax, or maybe directly from the Arabic, along with Spanish borrax and Italian borrace, the Arabic was بورق bauraq/bwrk, a word also used for borax. Traditional Arabic dictionaries say that it derives from the verb to glisten, which is also written بورق bwrq, but it seems to actually derive from the Persian būrah. The word borax is found in Arabic būraq, meaning white, which is from Middle Persian bwrk, another name for borax is tincal, from Sanskrit. The word tincal /ˈtɪŋkəl/ tinkle, or tincar /ˈtɪŋkər/ tinker, refers to crude borax, before it is purified, as mined from deposits in Tibet, Persia. The word was adopted in the 17th century from Malay tingkal and from Urdu/Persian/Arabic تنکار tinkār/tankār and these all appear to be related to the Sanskrit टांकण ṭānkaṇa

Oakland, California
–
Oakland /ˈoʊklənd/ is the largest city and the county seat of Alameda County, California, United States. The city was incorporated in 1852, Oaklands territory covers what was once a mosaic of California coastal terrace prairie, oak woodland, and north coastal scrub. Its land served as a resource when its hillside oak and redwood timber were logged to build San Francisco. In the late 1860s, Oakland was selected as the terminal of the Transcontinental Railroad. Following the 1906 San Francisco earthquake, many San Francisco citizens moved to Oakland, enlarging the citys population, increasing its housing stock and it continued to grow in the 20th century with its busy port, shipyards, and a thriving automobile manufacturing industry. Oakland is known for its sustainability practices, including a top-ranking for usage of electricity from renewable resources, in addition, due to a steady influx of immigrants during the 20th century, along with thousands of African-American war-industry workers who relocated from the Deep South during the 1940s. Oakland is the most ethnically diverse city in the country. The earliest known inhabitants were the Huchiun Indians, who lived there for thousands of years, the Huchiun belonged to a linguistic grouping later called the Ohlone. In Oakland, they were concentrated around Lake Merritt and Temescal Creek, in 1772, the area that later became Oakland was claimed, with the rest of California, by Spanish settlers for the King of Spain. In the early 19th century, the Spanish crown granted the East Bay area to Luis María Peralta for his Rancho San Antonio, the grant was confirmed by the successor Mexican republic upon its independence from Spain. Upon his death in 1842, Peralta divided his land among his four sons, Most of Oakland fell within the shares given to Antonio Maria and Vicente. The portion of the parcel that is now Oakland was called encinal—Spanish for oak grove—due to the oak forest that covered the area. In 1851, three men—Horace Carpentier, Edson Adams, and Andrew Moon—began developing what is now downtown Oakland, on May 4,1852, the Town of Oakland incorporated. Two years later, on March 25,1854, Oakland re-incorporated as the City of Oakland, with Horace Carpentier elected the first mayor, the city and its environs quickly grew with the railroads, becoming a major rail terminal in the late 1860s and 1870s. In 1868, the Central Pacific constructed the Oakland Long Wharf at Oakland Point, a number of horsecar and cable car lines were constructed in Oakland during the latter half of the 19th century. The first electric streetcar set out from Oakland to Berkeley in 1891, at the time of incorporation, Oakland consisted of the territory that lay south of todays major intersection of San Pablo Avenue, Broadway, and Fourteenth Street. The city gradually annexed farmlands and settlements to the east and the north, Oaklands rise to industrial prominence, and its subsequent need for a seaport, led to the digging of a shipping and tidal channel in 1902. This resulted in the town of Alameda being made an island

United States
–
Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

Miner
–
A miner is a person who extracts ore, coal, or other mineral from the earth through mining. There are two senses in which the term is used, in its narrowest sense, a miner is someone who works at the rock face, cutting, blasting, or otherwise working and removing the rock. In a broader sense, a miner is working within a mine. Mining is one of the most dangerous trades in the world, in some countries, miners lack social guarantees and in case of injury may be left to cope without assistance. Different functions of the individual miner, many of the roles are specific to a type of mining, such as coal mining. Roles considered to be miners in the narrower sense have included, Hewer, collier, a hewer who hews coal with a pick. Driller, who works a rock drill to bore holes for placing dynamite or other explosives, other roles within mines that did not involve breaking rock have included, Loader, who loads the mining carts with coal at the face. Putter, who works the carts around the mine, barrow-man, who transported the broken coal from the face in wheelbarrows. Hurrier, who transported coal carts from a mine to the surface, timberer, who fashions and installs timber supports to support the walls and ceiling in an underground mine. In addition to miners working underground, a mine employs other workers in duties at the surface, in addition to office staff of various sorts, these may include, Brakesman, who operate the winding engine. Mining engineers use the principles of math and science to develop solutions to technical problems for miners. In most cases, a degree in engineering, mining engineering or geological engineering is required. Because technology is changing, miners and mining engineers need to continue their education. The basics of mining engineering includes finding, extracting, and preparing minerals, metals and these mined products are used for electric power generation and manufacturing industries. Mining engineers also supervise the construction of mine operations and create ways to transport the extracted minerals to processing plants.

Mojave Desert
–
The Mojave Desert is an arid rain-shadow desert and the driest desert in North America. It is located in the southwestern United States, primarily within southeastern California and southern Nevada, very small areas also extend into Utah and Arizona. The central part of the desert is sparsely populated, while its peripheries support large communities such as Las Vegas, Lancaster, Palmdale, Victorville, the Mojave Desert is bordered by the Great Basin Desert to its north and the Sonoran Desert to its south and east. Topographical boundaries include the Tehachapi Mountains to the west, and the San Gabriel Mountains, the mountain boundaries are distinct because they are outlined by the two largest faults in California – the San Andreas and Garlock faults. The Mojave Desert displays typical basin and range topography and it occupies less than 50,000 sq mi, making it the smallest of the North American deserts. The Mojave Desert is often referred to as the desert, in contrast to the low desert. However, the Mojave Desert is generally lower than the Great Basin Desert to the north, the spelling Mojave originates from the Spanish language while the spelling Mohave comes from modern English. The Mojave Desert receives less than 13 in of rain a year and is generally between 2,000 and 5,000 feet in elevation, zion National Park in Utah lies at the junction of the Mojave, the Great Basin Desert, and the Colorado Plateau. Despite its aridity, the Mojave has long been a center of production, fed by irrigation coming from groundwater. The Mojave is a desert of temperature extremes and two distinct seasons, winter months bring comfortable daytime temperatures, which dip precipitously to around 20 °F on valley floors, and below 0 °F at higher elevations. Storms moving from the Pacific Northwest can bring rain and in places even snow. More often, the shadow created by the Sierra Nevada as well as mountain ranges within the desert such as the Spring Mountains, bring only clouds. By early June, it is rare for another Pacific storm to have a significant impact on the regions weather, summer weather is dominated by heat. Temperatures on valley floors can soar above 120 °F and above 130 °F at the lowest elevations, low humidity, high temperatures, and low pressure, draw in moisture from the Gulf of Mexico creating thunderstorms across the desert southwest known as the North American monsoon. Autumn is generally pleasant, with one to two Pacific storm systems creating regional rain events, october is one of the driest and sunniest months in the Mojave, and temperatures usually remain between 70 °F and 90 °F on the valley floors. After temperature, wind is the most significant weather phenomenon in the Mojave, during the June Gloom, cooler air can be pushed out into the desert from Southern California. In Santa Ana wind events, hot air from the desert blows out into the Los Angeles basin, wind farms in these areas generate power from these winds. The other major factor in the region is elevation

Public transport
–
Public transport modes include city buses, trolleybuses, trams and passenger trains, rapid transit and ferries. Public transport between cities is dominated by airlines, coaches, and intercity rail, high-speed rail networks are being developed in many parts of the world. Most public transport runs to a timetable, with the most frequent services running to a headway. Share taxis offer services in many parts of the world. Paratransit is sometimes used in areas of low demand and for people who need a door-to-door service, there are distinct differences in urban public transit between Asia, North America, and Europe. In Asia, mass transit operations are run by profit-driven privately owned and publicly traded mass transit. In North America, mass transit operations are run by municipal transit authorities. In Europe, mass transit operations are run by both state-owned and private companies. Public transport services can be profit-driven by use of pay-by-the-distance fares or funded by government subsidies in which flat rate fares are charged to each passenger. Services can be profitable through high ridership numbers and high farebox recovery ratios, or can be regulated. Fully subsidized, zero-fare services operate in some towns and cities, for geographical, historical and economic reasons, there are differences internationally regarding use and extent of public transport. It has 3,400 members from 92 countries, conveyances designed for public hire are as old as the first ferries, and the earliest public transport was water transport, on land people walked or rode an animal. Ferries appear in Greek mythology—corpses in ancient Greece were buried with a coin underneath their tongue to pay the ferryman Charon to take them to Hades, the omnibus was introduced to London in July 1829. The first passenger railway opened in 1806, it ran between Swansea and Mumbles in southwest Wales in the United Kingdom. In 1825 George Stephenson built the Locomotion for the Stockton and Darlington Railway in northeast England, the usability of different types of public transport, and its overall appeal, can be measured by seven criteria, although they overlap somewhat. These are speed, comfort, safety, cost, proximity, speed is calculated from total journey time including transfers. Proximity means how far passengers have to walk or otherwise travel before they can begin the public transport leg of their journey, timeliness is how long they have to wait for the vehicle. Directness records how far a journey using public transport deviates from the shortest route, an airline provides scheduled service with aircraft between airports

Key System
–
At its height during the 1940s, the Key System had over 66 miles of track. The local streetcars were discontinued in 1948 and the trains to San Francisco were discontinued in 1958. The Key Systems territory is served by BART and AC Transit bus service. The Key System began as the San Francisco, Oakland, and San Jose Railway, service began on October 26,1903 with a 4-car train carrying 250 passengers, departing downtown Berkeley for the ferry pier. The company touted its key route, which led to the adoption of the name Key System, in 1908, the SFOSJR changed its name to the San Francisco, Oakland & San Jose Consolidated Railway, changed to the San Francisco-Oakland Terminal Railway in 1912. This went bankrupt in December 1923 and was re-organized as the Key System Transit Co. transforming a marketing buzzword into the name of the company. Following the Great Crash of 1929, a company called the Railway Equipment & Realty Co. was created. In 1938, the became the Key System. During World War II, the Key System built and operated the Shipyard Railway between a station in Emeryville and the Kaiser Shipyards in Richmond. National City Lines acquired 64% of the stock in the system in 1946, jay Quinby hand published a document exposing the ownership of National City Lines. The new owners made a number of rapid changes, in 1946 they cut back the A-1 train route and then the express trains in 1947. The company increased fares in 1946 and then in both January and November 1947, during the period there were many complaints of overcrowding. They were convicted of conspiring to monopolize sales of buses and supplies and they were acquitted of conspiring to monopolize the ownership of these companies. In 1948 they proposed a plan to all the streetcars to buses. They placed an advertisement in the local papers explaining their plan to modernize and motorize Line 14, Oakland city council opposed the plan by 5–3. The Public Utilities Commission supported the plan which included large fare increases, in October 1948,700 people signed a petition with the PUC against the Key System, seeking restoration of the bus service on the #70 Chabot Bus line. The councils of Oakland, Berkeley and San Leandro opposed the removal of street cars, the traffic planners supported removal of the streetcar lines to facilitate movement of automobiles. Local governments in the East Bay attempted to purchase the Key System, Streetcars were converted to buses during November/December 1948

San Francisco
–
San Francisco, officially the City and County of San Francisco, is the cultural, commercial, and financial center of Northern California. It is the birthplace of the United Nations, the California Gold Rush of 1849 brought rapid growth, making it the largest city on the West Coast at the time. San Francisco became a consolidated city-county in 1856, after three-quarters of the city was destroyed by the 1906 earthquake and fire, San Francisco was quickly rebuilt, hosting the Panama-Pacific International Exposition nine years later. In World War II, San Francisco was a port of embarkation for service members shipping out to the Pacific Theater. Politically, the city votes strongly along liberal Democratic Party lines, San Francisco is also the headquarters of five major banking institutions and various other companies such as Levi Strauss & Co. Dolby, Airbnb, Weebly, Pacific Gas and Electric Company, Yelp, Pinterest, Twitter, Uber, Lyft, Mozilla, Wikimedia Foundation, as of 2016, San Francisco is ranked high on world liveability rankings. The earliest archaeological evidence of habitation of the territory of the city of San Francisco dates to 3000 BC. Upon independence from Spain in 1821, the became part of Mexico. Under Mexican rule, the system gradually ended, and its lands became privatized. In 1835, Englishman William Richardson erected the first independent homestead, together with Alcalde Francisco de Haro, he laid out a street plan for the expanded settlement, and the town, named Yerba Buena, began to attract American settlers. Commodore John D. Sloat claimed California for the United States on July 7,1846, during the Mexican–American War, montgomery arrived to claim Yerba Buena two days later. Yerba Buena was renamed San Francisco on January 30 of the next year, despite its attractive location as a port and naval base, San Francisco was still a small settlement with inhospitable geography. The California Gold Rush brought a flood of treasure seekers, with their sourdough bread in tow, prospectors accumulated in San Francisco over rival Benicia, raising the population from 1,000 in 1848 to 25,000 by December 1849. The promise of fabulous riches was so strong that crews on arriving vessels deserted and rushed off to the gold fields, leaving behind a forest of masts in San Francisco harbor. Some of these approximately 500 abandoned ships were used at times as storeships, saloons and hotels, many were left to rot, by 1851 the harbor was extended out into the bay by wharves while buildings were erected on piles among the ships. By 1870 Yerba Buena Cove had been filled to create new land, buried ships are occasionally exposed when foundations are dug for new buildings. California was quickly granted statehood in 1850 and the U. S. military built Fort Point at the Golden Gate, silver discoveries, including the Comstock Lode in Nevada in 1859, further drove rapid population growth. With hordes of fortune seekers streaming through the city, lawlessness was common, and the Barbary Coast section of town gained notoriety as a haven for criminals, prostitution, entrepreneurs sought to capitalize on the wealth generated by the Gold Rush

Nevada
–
Nevada is a state in the Western, Mountain West, and Southwestern regions of the United States of America. Nevada is the 7th most extensive, the 34th most populous, nearly three-quarters of Nevadas people live in Clark County, which contains the Las Vegas–Paradise metropolitan area where three of the states four largest incorporated cities are located. Nevada is officially known as the Silver State because of the importance of silver to its history and economy. It is also known as the Battle Born State, because it achieved statehood during the Civil War, as the Sage-brush State, for the plant of the same name. Nevada borders Oregon to the northwest, Idaho to the northeast, California to the west, Arizona to the southeast, Nevada is largely desert and semi-arid, much of it located within the Great Basin. Areas south of the Great Basin are located within the Mojave Desert, while Lake Tahoe, about 86% of the states land is managed by various jurisdictions of the U. S. federal government, both civilian and military. Before European contact, Native Americans of the Paiute, Shoshone, the first Europeans to explore the region were Spanish. They called the region Nevada because of the snow covered the mountains in winter. The area formed part of the Viceroyalty of New Spain, the United States annexed the area in 1848 after its victory in the Mexican–American War, and it was incorporated as part of Utah Territory in 1850. The discovery of silver at the Comstock Lode in 1859 led to a boom that became an impetus to the creation of Nevada Territory out of western Utah Territory in 1861. Nevada became the 36th state on October 31,1864, as the second of two added to the Union during the Civil War. Nevada has a reputation for its libertarian laws, in 1940, with a population of just over 110,000 people, Nevada was by far the least-populated state, with less than half the population of the next least-populated state. However, legalized gambling and lenient marriage and divorce laws transformed Nevada into a major tourist destination in the 20th century, Nevada is the only U. S. state where prostitution is legal, though it is illegal in Clark County, Washoe County and Carson City. The tourism industry remains Nevadas largest employer, with mining continuing as a sector of the economy. The name Nevada comes from the Spanish nevada, meaning snow-covered, most Nevadans pronounce the second syllable of their state name using the vowel of trap. Many from outside the Western United States pronounce it with the vowel of father, although the latter pronunciation is closer to the Spanish pronunciation, it is not the pronunciation preferred by most Nevadans. State Assemblyman Harry Mortenson proposed a bill to recognize the alternate pronunciation of Nevada, though the bill was not supported by most legislators, the Nevadan pronunciation is the de facto official one, since it is the one used by the state legislature. Nevada is almost entirely within the Basin and Range Province, and is broken up by many mountain ranges

Marsh
–
A marsh is a wetland that is dominated by herbaceous rather than woody plant species. Marshes can often be found at the edges of lakes and streams and they are often dominated by grasses, rushes or reeds. If woody plants are present they tend to be low-growing shrubs, Marshes provide a habitat for many species of plants, animals, and insects that have adapted to living in flooded conditions. The plants must be able to survive in wet mud with low oxygen levels, many of these plants therefore have aerenchyma, channels within the stem that allow air to move from the leaves into the rooting zone. Marsh plants also tend to have rhizomes for underground storage and reproduction, familiar examples include cattails, sedges, papyrus and sawgrass. Aquatic animals, from fish to salamanders, are able to live with a low amount of oxygen in the water. Some can obtain oxygen from the air instead, while others can live indefinitely in conditions of low oxygen, Marshes provide habitats for many kinds of invertebrates, fish, amphibians, waterfowl and aquatic mammals. Marshes have extremely high levels of production, some of the highest in the world. Marshes also improve water quality by acting as a sink to filter pollutants, Marshes are able to absorb water during periods of heavy rainfall and slowly release it into waterways and therefore reduce the magnitude of flooding. The pH in marshes tends to be neutral to alkaline, as opposed to bogs, Marshes differ depending mainly on their location and salinity. Both of these factors influence the range and scope of animal and plant life that can survive. The three main types of marsh are salt marshes, freshwater marshes, and freshwater marshes. These three can be found worldwide and each contains a different set of organisms, saltwater marshes are found around the world in mid to high latitudes, wherever there are sections of protected coastline. They are located close enough to the shoreline that the motion of the tides affects them and they flourish where the rate of sediment buildup is greater than the rate at which the land level is sinking. Salt marshes are dominated by specially adapted rooted vegetation, primarily salt-tolerant grasses, salt marshes are most commonly found in lagoons, estuaries, and on the sheltered side of shingle or sandspit. The currents there carry the fine particles around to the side of the spit. These locations allow the marshes to absorb the nutrients from the water running through them before they reach the oceans. Coastal development and urban sprawl has caused significant loss of these essential habitats, although considered a freshwater marsh, this form of marsh is affected by the ocean tides

Great Basin Desert
–
The Great Basin Desert is part of the Great Basin between the Sierra Nevada and the Wasatch Range. It is a desert with hot, dry summers and snowy winters. The desert spans a large part of the state of Nevada, and extends into western Utah, eastern California, the desert is one of the four biologically defined deserts in North America, in addition to the Mojave, Sonoran, and Chihuahuan Deserts. Basin and range topography characterizes the desert, wide valleys bordered by mountain ranges generally oriented north-south. There are more than 33 peaks within the desert with summits higher than 9,800 feet, the biological communities of the Great Basin Desert vary according to altitude, from low salty dry lakes, up through rolling sagebrush valleys, to pinyon-juniper forests. According to Grayson, more than 600 species of live in the floristic Great Basin. Sixty-three of these species have been identified as species of concern due to contracting natural habitats. The ecology of the desert varies across geography, also, different locations in the desert have different amounts of precipitation, depending on the strength of these rain shadows. The environment is influenced by Pleistocene lakes that dried after the last ice age, Lake Lahontan, each of these lakes left different amounts of salinity and alkalinity. The Great Basin Desert is defined by its animals and plants, scientists have different definitions of the Great Basin Desert, which are often defined by negatives. J. Robert Macey defines the Great Basin scrub desert as lacking creosote bush, the Great Basin Desert includes several arid basins lacking Larrea tridentata such as the Chalfant, Hammil, Benton, and Queen valleys, as well as all but the southeast portion of the Owens Valley. Conversely, the Panamint, Saline, and Eureka valleys have creosote bush, the study and definition of ecoregions can also indicate the boundaries of the Great Basin Desert. In 1987, J. M. Omernik defined a desert ecoregion between the Sierra Nevada and Wasatch Range, naming it the Northern Basin and Range ecoregion. In 1999, the U. S. EPA renamed the Northern Basin and Range to Central Basin and Range and he states that the Great Basin Desert is encompassed within that area. This article describes the ecology of the region, including the high-elevation areas. See Great Basin montane forests for more details on the high-elevation ecoregion. This is the climate of the high desert, the Great Basin desert climate begins with the Sierra Nevada in eastern California. Rising 14,000 feet above sea level, this mountain range casts a rain shadow over the desert

Central Pacific Railroad
–
It is now part of the Union Pacific Railroad. Many 19th century national proposals to build a railroad failed because of the energy consumed by political disputes over slavery. With the secession of the South, the modernizers in the Republican Party controlled the US Congress and they passed legislation authorizing the railroad, with financing in the form of government railroad bonds. These were all eventually repaid with interest, the government and the railroads both shared in the increased value of the land grants, which the railroads developed. The construction of the railroad also secured for the government the economical safe and speedy transportation of the mails, troops, munitions of war, planned by Theodore Judah, the Central Pacific Railroad was authorized by Congress in 1862. It was financed and built through The Big Four, Sacramento, California businessmen Leland Stanford, Collis Huntington, Charles Crocker, Crocker was in charge of construction. Construction crews comprised 12,000 Chinese emigrant workers by 1868 and they laid the first rails in 1863. The Golden spike, connecting the railroad to the Union Pacific Railroad at Promontory. Coast-to-coast train travel in eight days became possible, replacing months-long sea voyages and lengthy, in 1885 the Central Pacific Railroad was leased by the Southern Pacific Company. Technically the CPRR remained an entity until 1959, when it was formally merged into Southern Pacific. The original right-of-way is now controlled by the Union Pacific, which purchased Southern Pacific in 1996, the Union Pacific-Central Pacific mainline followed the historic Overland Route from Omaha, Nebraska to San Francisco Bay. Chinese labor was the most vital source for constructing the railroad, fifty Chinese laborers were hired by the Central Pacific Railroad in February 1865, and soon more and more Chinese men were hired. Working conditions were harsh, and Chinese men were compensated less than their white counterparts, Chinese men were paid thirty-one dollars each month, and while white workers were paid the same, they were also given room and board. Construction of the road was financed primarily by 30-year, 6% U. S. government bonds authorized by Sec.5 of the Pacific Railroad Act of 1862. The U. S. Government Bonds, which constituted a lien upon the railroads and all their fixtures, were repaid in full by the company as and when they became due. Sec.10 of the 1864 amending Pacific Railroad Act additionally authorized the company to issue its own First Mortgage Bonds in total amounts up to that of the bonds issued by the United States, such company-issued securities had priority over the original Government Bonds. Sec.3 of the 1862 Act granted the railroads 10 square miles of land for every mile laid, except where railroads ran through cities. This grant was apportioned in 5 sections on alternating sides of the railroad and these grants were later doubled to 20 square miles per mile of grade by the 1864 Act
