Randall, compiled data on the methods and appliances used at more than 500 power plants, in nine States, where bituminous coals were burned under boilers without smoke, the main purpose of the inquiry being to procure a basis for better practice at government plants. The information gathered has been tabulated for publication. A preliminary statement (Bulletin 334) dealing with the smoke problem and the essentials of smokeless combustion was published during the year. COKING AND WASHERT SECTIONS.
