about 4 by 5 feet square and 1 foot deep, 

 These vessels were sealed up so that they \\cro 

 gas-tight. Communicating with all of these 

 vessels were pipes connecting with the great 

 tank containing the saturated solution of salt, 



From the top or cover of each vessel is a 

 pipe running to a main pipe that carries off 

 the chlorine gas into another room as fast as 

 it is formed. Through each one of these ves* 

 sels a current of electricity passes; the whole 

 system consuming about 2000 horse-power, 

 The electric current, as it passes through tho 

 brine, separates the chlorine from the sodium, 

 the chlorine passing in the form of gas up 

 through the pipes, before mentioned, into the 

 main pipe, where it is carried into another 

 large room and discharged into a system of. 

 gas-tight chambers. Upon the floor of these 

 chambers is spread a coating of unslacked 

 lime ground into a fine powder. The lime has 

 a strong affinity for the chlorine gas and, 

 rapidly absorbs it, forming chloride of lime. 

 When the lime is fully saturated with the 

 chlorine the gas is turned off from that cham- 

 ber, which is then opened up and the chloride 

 taken out for shipment. A new coating of 

 lime is now spread in the chamber and the gas 

 is turned on and the process repeated. 



There are a number of these chambers, so 

 that the operation in all of its phases is going:
