Passage: When originally used in Olney, it is unknown what music, if any, accompanied the verses written by John Newton. Contemporary hymnbooks did not contain music and were simply small books of religious poetry. The first known instance of Newton's lines joined to music was in A Companion to the Countess of Huntingdon's Hymns (London, 1808), where it is set to the tune "Hephzibah" by English composer John Husband. Common meter hymns were interchangeable with a variety of tunes; more than twenty musical settings of "Amazing Grace" circulated with varying popularity until 1835 when William Walker assigned Newton's words to a traditional song named "New Britain", which was itself an amalgamation of two melodies ("Gallaher" and "St. Mary") first published in the Columbian Harmony by Charles H. Spilman and Benjamin Shaw (Cincinnati, 1829). Spilman and Shaw, both students at Kentucky's Centre College, compiled their tunebook both for public worship and revivals, to satisfy "the wants of the Church in her triumphal march". Most of the tunes had been previously published, but "Gallaher" and "St. Mary" had not. As neither tune is attributed and both show elements of oral transmission, scholars can only speculate that they are possibly of British origin. A manuscript from 1828 by Lucius Chapin, a famous hymn writer of that time, contains a tune very close to "St. Mary", but that does not mean that he wrote it."Amazing Grace", with the words written by Newton and joined with "New Britain", the melody most currently associated with it, appeared for the first time in Walker's shape note tunebook Southern Harmony in 1847. It was, according to author Steve Turner, a "marriage made in heaven ... The music behind 'amazing' had a sense of awe to it. The music behind 'grace' sounded graceful. There was a rise at the point of confession, as though the author was stepping out into the open and making a bold declaration, but a corresponding fall when admitting his blindness." Walker's collection was enormously popular, selling about 600,000 copies all over the U.S. when the total population was just over 20 million. Another shape note tunebook named The Sacred Harp (1844) by Georgia residents Benjamin Franklin White and Elisha J. King became widely influential and continues to be used.Another verse was first recorded in Harriet Beecher Stowe's immensely influential 1852 anti-slavery novel Uncle Tom's Cabin. Three verses were emblematically sung by Tom in his hour of deepest crisis. He sings the sixth and fifth verses in that order, and Stowe included another verse not written by Newton that had been passed down orally in African American communities for at least 50 years. It was originally one of between 50 and 70 verses of a song titled "Jerusalem, My Happy Home" that first appeared in a 1790 book called A Collection of Sacred Ballads:.

Passage: The United States Exploring Expedition led by Lieutenant Charles Wilkes was tasked with a vast survey of the Pacific Ocean starting in 1838. In September 1840 they arrived in Honolulu, where repairs to the ships took longer than expected. Wilkes decided to spend the winter in Hawaii and take the opportunity to explore its volcanoes while waiting for better weather to continue the expedition. King Kamehameha III assigned American medical missionary Dr. Gerrit P. Judd to the expedition as a translator.Wilkes sailed to Hilo on the island of Hawaiʻi and decided to climb Mauna Loa first, since it looked easier than Mauna Kea. On December 14 he hired about 200 porters, but after he left he realized only about half the equipment had been taken, so he had to hire more Hawaiians at higher pay. When they reached Kīlauea after two days, their guide Puhano headed off to the established ʻAinapō Trail. Wilkes did not want to head back downhill so he blazed his own way through dense forest directed by a compass. The Hawaiians were offended by the waste of sacred trees which did not help morale. At about 6,000 feet (1,800 m) elevation they established a camp called "Sunday Station" at the edge of the forest.
Two guides joined them at Sunday Station: Keaweehu, "the bird-catcher" and another whose Hawaiian name is not recorded, called "ragsdale". Although Wilkes thought he was almost to the summit, the guides knew they were less than halfway up. Since there was no water at Sunday Station, porters had to be sent back ten miles (16 km) to a lava tube on ʻAinapō Trail which had a known supply. After an entire day replenishing stocks, they continued up to a second camp they called "Recruiting Station" at about 9,000 feet (2,700 m) elevation. After another full day's hike they established "Flag Station" on December 22, and by this time were on the ʻAinapō Trail. Most of the porters were sent back down to get another load. 
Question: What is the name of the third station that was established on the hike by United States Exploring Expedition?

Ex Output:
Flag Station.

Passage: Charles-Valentin Alkan (French: [ʃaʁl valɑ̃tɛ̃ alkɑ̃]; 30 November 1813 – 29 March 1888) was a French-Jewish composer and virtuoso pianist. At the height of his fame in the 1830s and 1840s he was, alongside his friends and colleagues Frédéric Chopin and Franz Liszt, among the leading pianists in Paris, a city in which he spent virtually his entire life.
Alkan earned many awards at the Conservatoire de Paris, which he entered before he was six. His career in the salons and concert halls of Paris was marked by his occasional long withdrawals from public performance, for personal reasons. Although he had a wide circle of friends and acquaintances in the Parisian artistic world, including Eugène Delacroix and George Sand, from 1848 he began to adopt a reclusive life style, while continuing with his compositions – virtually all of which are for the keyboard. During this period he published, among other works, his collections of large-scale studies in all the major keys (Op. 35) and all the minor keys (Op. 39). The latter includes his Symphony for Solo Piano (Op. 39, nos. 4–7) and Concerto for Solo Piano (Op. 39, nos. 8–10), which are often considered among his masterpieces and are of great musical and technical complexity. Alkan emerged from self-imposed retirement in the 1870s to give a series of recitals that were attended by a new generation of French musicians.
Alkan's attachment to his Jewish origins is displayed both in his life and his work. He was the first composer to incorporate Jewish melodies in art music. Fluent in Hebrew and Greek, he devoted much time to a complete new translation of the Bible into French. This work, like many of his musical compositions, is now lost. Alkan never married, but his presumed son Élie-Miriam Delaborde was, like Alkan, a virtuoso performer on both the piano and the pedal piano, and edited a number of the elder composer's works.
Following his death (which according to persistent but unfounded legend was caused by a falling bookcase) Alkan's music became neglected, supported by only a few musicians including Ferruccio Busoni, Egon Petri and Kaikhosru Sorabji. From the late 1960s onwards, led by Raymond Lewenthal and Ronald Smith, many pianists have recorded his music and brought it back into the repertoire. 
Question: What is the last name of the person whose compositions were virtually all for the keyboard?

Ex Output:

Alkan.
