What were the first ocean-going steamships? Detailed answer Directory / Big encyclopedia. Questions for quiz and self-education Did you know? What were the first ocean-going steamships? Most ocean travel today is by air, although ocean liners still travel. Transatlantic travel on liners began in 1816. The first company to run ships on schedule was the Black Ball Company of New York. Her ships cruised between New York and Liverpool. Other lines soon began to appear. The first liners sailed. They were called postal because they carried mail and captured passengers. The ships were not very comfortable: first-class passengers traveled in small cabins, and fourth-class passengers had no cabins at all. They slept on bunks made of rough planks in narrow, low places provided for this purpose below deck. On some shipping lines, fourth-class passengers were required to carry groceries with them. Each passenger had to present his own supply of food before he was allowed to board the steamer. The food supply required included a large quantity of biscuits, flour, potatoes, tea, sugar, molasses, two hams, a tin pot, a frying pan, a mug, a teapot, a knife, a fork, and a spoon. In order to provide other passengers with milk and food, most mail ships had a cow and a brood of chickens. The first steamship to cross the Atlantic was the USS Savannah. In 1819 he made the journey from Savannah, Georgia to Liverpool in 29 days. The Savannah sailed almost all the way, and only when the wind subsided did she steam. Sails were left on all the first steamships, as sailors did not trust the power of steam. They were afraid that the steam engine would break down in the middle of the ocean or that there might not be enough fuel. One of the most famous steamships had paddle wheels and propellers. It was the ship "Great Oriental". It was 210 meters long, 25 meters wide and for forty years remained the largest ship in the world. Author: Likum A. Random interesting fact from the Great Encyclopedia: When was surgery first used? With modern hospitals and surgeons capable of performing any operation on the body, we believe that surgery is a modern phenomenon. In fact, surgery has been practiced since ancient times. Ancient people around the world used flint tools as surgical tools. One of the most dangerous and difficult operations performed on the skull has been performed with flint tools since ancient times. And it was in prehistoric times. Flint tools were also used for opening abscesses and bloodletting. Other "tools" for this purpose were the teeth of fish and even the sharp thorns of plants. The cataract was removed from the eye with spikes. The need for tools began to grow, and amputation saws appeared instead of flint tools. This is absolutely accurate, because many of the mummies found show the results of such operations. When people learned to make tools from bronze and iron, scissors, iron needles and other complex tools were invented. With these improved tools, people performed more difficult operations. There are records that prove that most of the operations carried out today, including complex ones, were carried out in ancient times. Among the relics of Pompeii are very complex surgical instruments. Operations were performed for thousands of years without anesthesia, which brought a person to an unconscious state. There was also a lack of knowledge on how to avoid infection. Operations began to be carried out when nothing was known about the causes of diseases. But they must have been generally successful, otherwise they would not have continued. Two discoveries made modern surgery possible: the advent of anesthesia and means of preventing infection.
