Sea rafting is the best in the world.

In modern times, the first person to detect ocean currents with a drift bottle was Benjamin Franklin, an American with a wonderful idea about the ocean. He has many interests, such as painting, law and electricity. However, what attracted him most was the vast ocean. Franklin was the deputy director of the General Post Office long before the American Revolution. 1769 One day, a group of Boston shopkeepers protested to him. They asked, "Why does it take the British mail ship two weeks longer to cross the Atlantic than the American mail ship? Aren't we sailing in the same Atlantic? The navigation technology of British mail ships is too backward. " Franklin talked to his cousin Moses Folg about it. Folg was the captain of a whaling ship in New England. He told Franklin that American ships sailed along the Gulf of Mexico in the east, but when they returned, they avoided the original channel and did not sail against the current, while British ships did not. At that time, Franklin couldn't understand why the British captain didn't go downstream in the Gulf of Mexico, which would shorten the time of sailing eastward. When you return, you should not avoid sailing against the current. Franklin asked his cousin to draw the Gulf of Mexico on a chart. Later, he threw the drift bottle into the Gulf Stream. There is a note in the bottle: the discoverer of this bottle immediately wrote to inform the location and time of discovery. This method is still used by our modern oceanographers today. Based on the feedback from countless drift bottles, Franklin carefully examined the direction of the Gulf Stream, then drew a chart of the current, and sent a copy to Plymouth's General Administration of Navigation. He hopes that the British captain can use this chart. But Britain was a maritime power at that time, and sold their charts to all countries in the world, so it naturally disdained the charts sent by Franklin. In other words, will American postmen be more familiar with electricity than old sailors? However, history has proved that the chart of Gulf Stream discovered and drawn by Franklin with a drift bottle does not need to be changed today. Another Albert I who is interested in Atlantic water flu. He is a Moroccan prince and is called an oceanographer. Albert I used four speedboats to detect the current in the ocean. He asked the captain to put the drift bottle with letters into the designated place in the Atlantic Ocean. From 1885 to 1888, he dropped 1700 bottles. In the next 10 years. Albert I received 227 letters and learned the location and arrival time of these bottles. Accordingly, Abbott also drew several new Atlantic charts. In the 20th century, some missionaries also followed the fashion and used drift bottles to spread religion, so they were called "drift bottle missionaries". In Mittel Paul, a small town in the mountains of Kentucky, a man named Harrison Meiers washed several whisky bottles and stuffed publicity materials in 16 languages into the bottles. On 195 1, it was thrown into the vast sea. 1974, 70-year-old meyers received a letter from the Philippines. The sender said that he found a drift bottle from meyers, which was one of many that was thrown into the ocean 23 years ago. It is verified that this drift bottle was thrown into the ocean by Nicaraguan meyers in Central America. Another "drifting bottle missionary" named Ray Flanders Chul Bias lived in Piedmont Plateau, Alabama. From 1946 to1955; 3,000 religious drift bottles were dropped from alabama river. These bottles will flow with the water to the Gulf of Mexico. However, Pias never announced how many replies he received. There is also a "drift bottle missionary" named Rhett George Philip who lives in Tacoma, Washington. He once announced to the press that he had received an echo of the propaganda materials of the drift bottle. From 1949, he picked up whisky and drink bottles in the trash can of the restaurant. In the next 20 years, he always threw 1500 bottles into Puget Sound and let the current load them into the Pacific Ocean. All the bottles thrown into the sea are put in a publicity material, asking people who see them to give up drinking. This is a serious problem that Rhett George experienced personally. He himself had a fierce struggle against alcoholism and won. 20 years later. George claimed that he had received 65,438+0,400 letters, mostly from towns along the Pacific coast and Mexico, but also from Hawaii and New Guinea. According to statistics, out of every 10 letter, 7 promised to give up drinking. Two of them said that they promised to go back to church and confess to the priest. The others told him when and where the bottle was found. The most striking letter was written by a businessman in Chicago. The letter said: whisky destroyed his family; The shop already belongs to someone else; His wife left him. He fled to Mexico in despair. One day, he found a drift bottle thrown by red George at the seaside near Kaburu. At the end of the promotional materials, there is a sentence: "Sin is like a wake-up call, which will definitely clear your head." This sentence shocked him greatly. He deeply felt that this sentence was a good medicine for his heart disease. So he immediately wrote back to Rhett George: "I'm going back to Chicago!" " "He also wrote:" I want to cheer up and start my life again. "Two years later, Rhett George received this man's second letter. He claimed that he worked hard every week to pay off his debts and his wife had come back. At the end of the letter, he wrote: "Everything I have now is given by a drift bottle in the Atlantic Ocean. "
