Lakes of Titan
The lakes of Titan, a moon of Saturn, are made of liquid methane. The lakes were found by the "Cassini-Huygens" space probe. The larger lakes are known as maria (seas) and the smaller ones as lacūs (lakes).
It was possible that there were seas of liquid methane on Titan and first suggested after reading Voyager 1 and Voyager 2 information that showed Titan to have a thick atmosphere, capable of supporting lakes, but exact evidence was not found until 1995 when pictures from the Hubble telescope and other telescopes had already shown some proof of liquid methane possibly in lakes or planet-wide oceans, similar to oceans on Earth.
The "Cassini" mission proved there are liquid lakes on Titan, but not at first. When the probe arrived in the Saturnian system in 2004, scientists hoped that hydrocarbon lakes or oceans might be seen in reflected sunlight from the surface, but no reflections were found.
Scientists still believed that liquid ethane and methane would be found near Titan's poles, where they expected to find lots of liquid. At Titan's south pole, a large dark area named Ontario Lacus was the first lake identified, possibly created by rain as clouds are often seen in the area. A possible shoreline was also identified at the pole in radar images. As the Huygens-Cassini probe flew by on July 22, 2006, its radar took pictures of the northern part of the planet (which was in its winter), a number of large, smooth areas were found on the surface near the northern pole. Based on this data, scientists announced "definitive evidence of lakes filled with methane on Saturn's moon Titan" in January 2007. The "Cassini–Huygens" team decided that the smooth areas are the hydrocarbon lakes they had been searching for, the first lakes found off Earth. Some valleys appear to have rivers.
The satellite was not able to show pictures of lakes moving in the wind. The heavy moisture and clouds of methane near Titan’s surface could be a sign of evaporation from lakes. The lakes cover 0.002–0.02% of Titan's surface.
The "Cassini-Huygens" probe flew by in February, 2007, taking radar and camera pictures of some large areas near the north pole that may be large areas of liquid methane and/or ethane, including one sea larger than 100,000 km² (larger than Lake Superior), and another area similar in size to the Caspian Sea. Pictures taken near Titan's southern pole in October 2007 showed similar, but far smaller, areas that look like lakes.
The Cassini-Huygens probe, flew very close to Titan in December 2007, and took infrared pictures of the chemicals on the surface and found a lake called Ontario Lacus near the south pole. Scientists studying the infrared pictures decided that one or more of the large lakes in the pictures of Saturn's moon Titan does hold liquid and that the liquid is made of hydrocarbons. They have also found ethane on Titan. This mission proves Titan to be the only other planet known to have liquid on its surface. The lakes make Titan a very important planet for studying weather science. Liquids, gases and temperatures are at play on Titan. This should help the science of weather forecasting.
Lakes were not found near near Titan's center of Titan which was studied on January 14, 2005. A part of the Huygens-Cassini probe landed there. The pictures taken by the probe as it fell showed no open areas of liquid, but showed rivers that had dried. It was at first thought that dark areas near the center of Titan could be a lake of a liquid or tar-like substance, but the probe landed on the dark area, and it is solid without any liquid. A device known as a penetrometer studied the surface as the probe landed and seemed to find wet clay. Scientists believe that the penetrometer may have landed on a large pebble, and they say that the surface is similar to sand made of ice. Pictures taken after the probe landed show a large flat area covered in pebbles. The pebbles may be made of water ice and are partly rounded, which indicates fluids.
On February 13, 2008, scientists said that Titans polar lakes contain "hundreds of times more natural gas and other hydrocarbons than all the known natural gas on Earth." The desert near the center of the planet are not liquid but do have more organics than Earth. In June 2008, "Cassini"'s Visible and Infrared Mapping Spectrometer confirmed the presence of liquid ethane beyond doubt in a lake in Titan's southern hemisphere.
Predictions of Titan's clouds are that during in a Saturnian year, liquid moves from the equator to the poles, in clouds, and falls as rain.
Titanian "maria" (large hydrocarbon seas) are named after sea monsters of Earth.
Areas named "Lacus" are believed to be methane lakes. They are named after lakes on Earth.
West Coast blues
The West Coast blues is a type of blues music related to jazz and jump blues, with lots of piano sounds and jazz guitar solos, which originated from Texas blues musicians that moved to California in the 1940s. West Coast blues also uses smooth, honey-toned vocals, often sounding similar to urban blues.
Texas and the West Coast
The best known West Coast blues musicians may be guitarist T-Bone Walker, famous for the song "Call It Stormy Monday (But Tuesday Is Just As Bad)", originally from Texas, he had made his first recordings in the late 1920s. During the early 1940's Walker moved to Los Angeles, where he recorded a lot of music for Capital, Black & White, and Imperial. Walker an electric guitar sound to the blues, prossibly doing more to make the use of electric guitar popular in blues than anyone else. Much of his material had a jazzy jump blues feel, which is typical of popular blues from California in the 1940s and 1950s. Other Texas bluesmen followed: Pianist/songwriter Amos Milburn, singer Percy Mayfield, famous for the song "Hit the Road Jack", and Charles Brown moved to Los Angeles. Guitarist Pee Wee Crayton divided his time between Los Angeles and San Francisco, while Lowell Fulson, from Texas by way of Oklahoma, moved to Oakland.
After the efforts of Tom Mazzolini, producer of the San Francisco Blues Festival, started in 1974, and the efforts of recording companies like Arhoolie and HighTone, the West Coast is one of the most important blues areas in the country.

Frederick Pottinger
Sir Frederick William Pottinger, 2nd Baronet (1831–1865), police inspector, was born on April 27, 1831, in India. He became famous for leading the New South Wales police in their hunt for the bushrangers Ben Hall, John Gilbert, Frank Gardiner and John Dunn.
He was the son of Lieutenant-General Sir Henry Pottinger of the British East India Company, and his wife Susanna Maria, née Cooke, of Dublin. Henry Pottinger was the first Governor of Hong Kong. Frederick went to Eton from 1844 to 1847. Between 1850 and 1854, Pottinger was an officer in the Grenadier Guards in England. He lost a lot of his mother's money gambling on horse races. In 1856 he took the place of his father as second baronet. He soon gambled away all his money. He owed people a lot of money.
He went to Australia to search for gold. He joined the New South Wales police force as a mounted trooper. He was an excellent horse rider and spent the next few years working on the gold escort between Gundagai and Goulburn.
Pottinger kept his title secret but in 1860 the inspector-general of police, John McLerie, found out. He was quickly given better jobs. In November he became clerk of petty sessions at Dubbo and on October 1, 1861, assistant superintendent of the Southern Mounted Police Patrol. He wanted to do a good job in the police, but he got into a drunken brawl at Young on 20–21 December 1861. He was a publicly warned about his bad behaviour. He was sent to the Lachlan River area. He showed he was a busy but unlucky hunter of bushrangers.
