AUTOBIOGRAPHY OF JOHN FRITZ 87
It had already been shown to the satisfaction of us aU that the intermediate or second working was now, beyond any question, injurious, and should at once be abandoned, but the question of the first working, after casting, known amongst furnace men as cinder raising, was not so easily cUsposed of. The long forehearth was filled with coal dirt and loam. After casting and after the blast had been put on, the cinder would, in the course of an hour or more, come up to the tuyeres. The blast was then slackened, the plate heretofore designated was taken off, the coal dirt and loam was shoveled out up to the tymp, and the cinder flowed in and fUled the place up and was aUowed to run out until it was level with the tapping hole on the dam plate. Then the cinder was covered with loam, and the heavy plate was placed in position again, and the blast put on; then the cinder was tapped as often as it came up to the tuyeres until casting time came around.
It was now arranged that at the next cast the loam and coal dirt should be shoveled out to about eight inches from the tymp and the space be ffiled with loam, well rammed down up to that point and a narrower plate put on, and that at cinder raising, instead of opening up and working the furnace, a single bar should be driven in under the plate imtil it reached the cinder and then be withdrawn. It was supposed that the cinder would flow out after the bar was removed.
The next morning Mr. ColUns was on hand at casting time and had the forehearth filled up as before arranged, and when the blast was put on he said to the furnace men in the most emphatic manner and in language that would not be becoming to a church member that if any man put a bar into the furnace other than in tapping for cinder he would at once discharge him. We now had an anxious wait of an hour or so to know what the result might be; we
