Other improvements during the year included modernization of the arsenic plant and installation of new ore-handling facilities to increase capacity to 200 tons an hour, replacing facilities which had been installed before they took over the Tacoma plant in 1905. Ordered by American Air Filter Company, c/o R.E. Chase & Company, Mr. Warren.
