The two reaction and settling tanks are: 24 ft. 6 in. indiameter, 19 ft. 4 in. high, dressed Washington fir, 2^4 , fitted with round steel hoops and malleable irondraw lugs. Tanks are provided with steel ladder outside andwooden ladder inside with platform at top of outside ladder,both tanks are covered.

The boilersare equipped with automatic soot blowers and the customaryinstruments to enable the engineers to operate the boiler intel-ligently. The flue gases are carried away by two radial brickchimneys. The chimneys were built by the Canadian Kellogg Com-pany.
