On completion of tests with gas producer, it was disconnect-ed and the regular grates placed in tire-box of boilers. Aseries of tests was then made with same fuels burned in usualmanner. The figures shown in attached tabulated statementare totals and averages of three tests with eacli fuel and methodof combustion, a total of 36 tests having been made.
