Thecoal was applied to only half the tuyeres on each sideof the furnace, being introduced to alternate tuyeres,those on the front of the furnace being staggered withthose at the back. Mr. Garred experimented with checkor explosion valves, which were placed in the branchpipes. It was found these check valves were not effec-tive except when they were carefully designed andplaced in every branch pipe, and this a complicationof apparatus that was not considered desirable. Itwas then found that if any individual tuyere waschoked, the coal was drawn into the bustle pipe bysuction and found its way down the branch pipes leading to tuyeres that were open. It was thereforeagreed that any possibility of e
