The water, having been separated from the air, leaves the camera aeolis at the same speed as it enters. It then drives a water wheel, which in turn drives the musical cylinder and the movements attached. To start the organ, the tap above the entry pipe is turned on and, given a continuous flow of water, the organ plays until the tap is closed again.
During the Renaissance many Italian gardens had water organs. The most famous water organ of the 16th century was at the Villa d'Este in Tivoli. It was about 6 metres high and was powered by a beautiful waterfall. It could play three pieces automatically, but there was also a keyboard.
User interface
A User interface allows a user to interact with a machine. User interfaces mainly provide two things:
Many machines can be very dangerous. A machine should have a user interface that can be handled easily, even if the person operating the machine has panicked. The user interface should therefore be intuitive, and simple to use. An example of such a user interface is that of the kill switch. A kill switch must shut off the machine at all costs - the idea is to avoid injury or harm to people. This is very different from shutting off the machine at the end of the shift, or when it is no longer needed.
According to EN ISO 13850, the kill switch has to be red on a yellow background.
The colors used to mark different states are close to those used by signals used on the road.
There may be additional symbols, for example:
In many cases, such symbols are better, because some people are color blind. They need to be explained, like warnings, though.

A chrysalis is the pupa of a butterfly. The word "chrysalis" comes from the Greek language word for gold because butterflies often have a brighter pupa than other insects.
Artibonite (department)
Artibonite is one of the ten departments (French: "départments", singular "départment") of Haiti. It is named Artibonite because the Artibonite river flows across the department from east to west. Its capital is Gonaïves.
The independence of Haiti was proclaimed in the "Place d'Armes" of Gonaïves on 1 January 1804 by Jean Jacques Dessalines.
The "Départment de l'Artibonite", with an area of 4,895 km², is the largest department of Haiti.
The main river of the department is the Artibonite. Other rivers are Ennery, de l'Estère, Montrouis, Quinte.
The mountain chains here run from west to east and the most important are the "Chaine de Terre-Neuve" and the "Montagnes Noires" (in English, "Black Mountains"). There is also part of the "Chaine des Mattheux".
It is bordered to the northwest by the Nord-Ouest Department, to the north and northeast by the Nord Department, to the east by the Centre Department and to the south by the Ouest Department. The Gulf of Gonâve is to the west.
The department had, in the 2003 census, a population of 1,299,398 persons: 625,690 men and 673,708 women, with 422,476 (32.51%) living in cities and towns.
The main cities are Gonaïves (the capital) and Saint-Marc.
The department is divided into five "arrondissements" (like districts) and 15 "communes" (like municipalities). The "arrondissements" and their "communes" are:
Most of the rice of Haiti is grown in the Artibonite department, along the valley of the River Artibonite.
Bohemianism
The word Bohemian was first used in Paris to mean a Gypsy because many people thought that Gypsies came from Bohemia. The word was then used in the late 19th century (1800s) for poor painters, writers, musicians and actors who often travelled to Paris from other towns and tried to earn money. Paris was a famous town for painters, writers, and musicians to gather, to learn from each other and to enjoy the life of the city. Many of them lived at Montmartre, not far from the "Moulin Rouge". One of the most famous painters to live in Montmartre was Henri Toulouse-Lautrec. He loved to paint the can-can dancers and prostitutes. He did many posters to advertise the nightclubs. The posters are now famous works of art.
In the 20th century the word "Bohemian" spread to other countries and was used to describe the lives of many different artists of different sorts. The sort of behaviour that was thought of as "Bohemian" included whether a person had a regular job, how they dressed, their political views, their religious views, their sexual behaviour and the entertainment they liked.
People who were called "Bohemians" were often very poor, because they tried to live by painting, acting or writing. It was hard to make a living. They generally wore old or second-hand clothing, and could not afford a good hair-cut. They often shared the room in the roof of a house, which was cheap, because it was cold in winter, hot in summer and often had birds living there as well. In some ways the life of a bohemian artist was difficult, but it gave people freedom to express themselves, that was often not found in more conservative society, where everyone worried about what other people thought of them, and cared a lot about things like clothes and houses. Sometimes students from richer families would come to live a "Bohemian life style", so that they could feel the same freedom to express themselves.
During the 20th century, many cities apart from Paris have areas where people have lived Bohemian lifestyles. One of the problems is that these areas often become fashionable for rich people. This soon drives away the poor artists and students, because they can no longer afford the rent.
Bohemian areas in different cities are:
Henry Willis
Henry Willis (born: 27 April 1821, London - died: 11 February 1901, London) was a British builder of pipe organs. He built a very large number of organs, many of them for big cathedrals and concert halls in Britain, such as St. Paul's Cathedral, Truro Cathedral, and the Royal Albert Hall. He also built an organ for Queen Victoria at Windsor Castle. Many of the organs that he built are in other parts of the world, especially in countries that belonged to the British Empire.
Many organists who gave organ recitals liked Henry Willis’s organs because they had lots of different sounds which helped to make the organ sound like an orchestra. He made organs for churches where the architects were getting rid of the central screen so that the organ could be heard better in the main part of the church (the nave). He used ideas that had been created by the French organ builder Cavaillé-Coll and by Barker. He made several inventions himself, including the thumb piston, which made it possible for an organist to change the combination of stops without taking his hands off the keyboard.
Four generations of the Willis family continued the family tradition of organ building until 1997, when Henry Willis IV retired and the new Managing Director of the firm was not a member of the Willis family. The Company, founded in 1845, Henry Willis & Sons, Ltd. still makes organs in Liverpool.
