Q: Question: When did the river in which Major Long took an 1823 expedition change it's name? Passage 1:Major Long's 1823 expedition up the Minnesota River (then known as St. Peter's River), to the headwaters of the Red River of the North, down that river to Pembina and Fort Garry, and thence by canoe across British Canada to Lake Huron is sometimes confused with his initial expedition to the Red River in modern-day Texas and Oklahoma. The expedition to the Red River of the North was a separate, later appointment which completed a series of explorations conceived of by Lewis Cass and implemented by David B. Douglass, Henry Schoolcraft, and others besides Major Long. The 1823 expedition was denoted primarily as a scientific reconnaissance and an evaluation of trade possibilities, but probably had undisclosed military objectives as well, and certainly was viewed with suspicion by British authorities in Canada. This expedition for a time was joined by the Italian adventurer Giacomo Beltrami, who argued with Long and left the expedition near Fort Garry. The 1823 expedition encouraged American traders to push into the fur trade in Northern Minnesota and Dakota, and fostered the development of the Red River Trails and a colorful chapter of ox cart trade between the Red River Colony and Fort Garry via Pembina and the newly developing towns of Mendota and St. Paul.
Passage 2:He made his senior debut in a First Division clash with Wigan Athletic on 14 October 2003; he replaced Clint Hill on the 80 minute mark, as Stoke lost 21 at the JJB Stadium thanks to two Geoff Horsfield goals. Four days later he made a further cameo against Ipswich Town. To gain first team experience he spent the second half of the 200304 season on loan at Second Division side Oldham Athletic. He scored his first senior goal at Boundary Park, in a 41 win over Plymouth Argyle on 17 April. Upon his return to the Potteries he won his home debut at the Britannia Stadium; he played the full ninety minutes in what was a 41 win over West Bromwich Albion.
Passage 3:The New Adventures of Pinocchio is a syndicated stop motion animated television series produced by Rankin/Bass Productions in the United States and made by Dentsu Studios in Japan. Created by Arthur Rankin, Jr. and his partner Jules Bass, it was based on the book The Adventures of Pinocchio written by Italian author, Carlo Collodi. The series was Rankin/Bass' first production to be made in "Animagic", a stop motion puppet technique which, in association with the company, was done by Tadahito Mochinaga's MOM Productions (before Mochinaga leaves for China after the finished animation for Mad Monster Party?). A total of 130 five-minute "chapters" were produced in 196061. These segments made up a series of five-chapter, 25-minute episodes. During 196364, the series was also aired in Japan on Fuji TV as part of another stop motion TV series, Prince Ciscorn (, lit. Ciscorn Oji), based on the manga by Fujiko Fujio and also produced by Tadahito Mochinaga for Studio KAI and Dentsu.
