RECEPTION AND SETTLING OF BRINE. 



The salt manufacturer having satisfied himself in regard to the 

 quantity and quality of the brine supply, must now be prepared 

 with cisterns to store his brine during the process of settling. 



These cisterns or outside settlers were formerly built in size 

 20 by 30 feet and 6 feet deep, having a capacity of 25,000 gallons. 

 More recently the size of these has been increased to suit the wants 

 of the manufacturer. They are built of sound 2 to 3 inch plank, 

 well and properly keyed together by strong gripes, and are also 

 calked to prevent leakage. These cisterns are elevated on piling 

 or framed timbers, high enough to allow the settled brine to flow 

 through pipes to the blocks. 



The connections from the cisterns into the pipes are 6 inches
