When the fpace from the top of the veffel B, to the furface 

 of the well is equal to 18 ket, the top of the chamber H, 

 above the bottom of F, and the perpendicular height of the 

 pipe L, above the bottom of the chamber K, may be each 18 

 feet. 



The valves and every other part of the apparatus being in 

 proper order for work ; the well being tilled with water ; and 

 the refervoir R conftantly fupplied, fo as to overflow in one 

 part fomewhat lower than the reft of the brim, while the 

 higher orifice of the pipe A A, is about two lines below the 

 furface of the water, and takes in its full quantity ; the manner 

 of bringing this machine into action, and its operation after- 

 wards, may be underftood by attending to the following di- 

 rections, and ftatement of particulars: 



Open the pipe E which leads to the chamber F, by turning 

 the cock C, and water will defcend into F from the ciftern 

 R, by the pipe I : When the chamber is full, place the two 

 connected buckets M, in a horizontal petition, and the cock 

 C, if properly conftructed and connected with thefe buckets, 

 will cut off all communication between the pipe C C and the 

 pipes E G. The air carried down the pipe A A, by the 

 column of water which defcends and keeps the well conftantly 

 overflowing, will afcend into, and gradually expel a quantity 

 of water from the pipe C C, and afterwards that contained 

 in the higher part of the veffel B alfo. The float receiving 

 an acceflion of weight by being Qut of water, will defcend 

 and let down the re-curved fyphon S, which will pour water 

 upon the buckets below. At this period deprefs that bucket 

 which by defcending opens a communication between the 

 pipes C and E, and no farther attendance will be requifite. 



The preflure of the column in the well, above 18 feet high, 

 being thrown upon the water in the chamber F, by the inter- 

 vention of the condenfed air in the pipe C, the valve in the 

 pipe I will be fhut, and water will afcend from the chamber 

 F through the pipe K K into H ; the fyphon S will alfo 

 afcend into its place, and ceafe to draw water from the 



ciftern.
