Question: Question: How much time was between the periods? Passage:Prior to Nepal’s unification, Srēṣṭha was a collective high-status title given to those Hindu clans referred to as 'Bhāju' (from Sanskrit bhadralok) who served as the key non-Brahmin class of ruling, administrative and merchant class of the Malla courts. From within this broad Srēṣṭha groups are two distinct caste groups. First, they count among them the high-caste aristocratic Kshatriyas, locally pronounced as Chatharīya, who are descended from the nobles and courtiers of the Malla period and consist of the ruling, land-owning and literate Hindu caste group of the Nepal Mandala, which later formed the core of government bureaucracy during the Shah and Rana period. Second, Srēṣṭha title is also attributed to the Pāñchthariya, who now mostly write their surnames as 'Shrestha', who were historically the Hindu merchant clans of the Valley, as opposed to the Buddhist merchant caste of Urāy. These Pāñchthariyas have Vaishya status in the traditional varna framework. Srēṣṭha group has also incorporated in it the socially upward Jyapu farmers and other peasants especially outside the Valley as a means of the Sanskritisation process, although their status is not accepted by the upper-level Srēṣṭha castes.

Question: Question: Is the power plant at Old Salt Lake still in use? Passage:The Old Salt Lake was used by the Chowigna Indians who dug up salt from the bottom. Old Salt Lake was in what is now Redondo Beach, California. In 1856 Henry Johnson and lawyer William Allanson purchased the Old Salt Lake land and built a salt evaporation pond to make and sell salt. The site of Old Salt Lake was designated a California Historic Landmark (No.373) on Sept. 6, 1941. On December 15, 1854 Manuel Dominguez sold 215 acres of the Rancho San Pedro for $500 to Los Angeles businessmen Henry Allanson and William Johnson. Johnson and Allanson also built a boiling house with 48 wood fired kettles to make salt faster than the evaporation pond. Johnson and Allanson exported much of the salt produced by transporting it 10 miles overland to the Port of San Pedro. Spanish Missionaries also dug up salt from the lake in the time of Spanish missions in California. The Salt lake was a large pond that was 600 by 1800 feet, it was fed by a natural spring. Johnson and Allanson shut down the salt works in 1862 and sold it to businessman, Frances Mellus. Frances Mellus ran the Pacific Salt Works at the site until 1881. In 1881 Liverpool Salt Works at the Salton Sea, a rival company, purchased Pacific Salt Works and the closed. The lake was 600 feet from the Redondo Beach sea shore at an elevation of about 10 feet. In 1955 a granite marker was put up at the site on Harbor Drive near the AES electricity power plant. In 1901 the fire boiler were removed and the buildings were abandoned for almost 20 years, in 1924 all structures at the site were removed. Southern California Edison built the south Bay power plant on the site in 1948. In 1998 AES Corporation purchased the power plant.
