Storage tanks. For the purpose of collecting the tar 

 and liquor from the various syphons and run-offs, a cir- 

 cular underground brick tank was built, the inside 

 measurements being 12 feet by 12 feet. For 6 feet in 

 height, the tank wall is 14 inches thick, and the remainder 

 9 inches thick. An area 16 feet diameter was first exca- 

 vated, and over the whole area concrete to the depth of 

 1 2 inches was laid. A backing of puddle not less than 

 1 2 inches thick is well worked in behind the tank wall. 

 Capacity, 8,400 gallons.
