AUTOBIOGRAPHY OF JOHN FRITZ 153
take our chance and build a Bessemer plant. We did this very reluctantly, as we could not see sufficient ore in sight to warrant a supply for any great length of time. We would have to take our chances and would have to rely to some extent on importation, probably of both ore and pig iron, and on the hope that more low-phosphorus ores might be discovered.
We started the foundations of the building in the fall of 1868.
In building the Bessemer plant and the rolUng mill I made a new departure. In place of building separate buildings for the Bessemer plant, and also for the various roll trains, I built a good substantial stone bmlding, 931 feet in length and iii feet in width, with four transepts, two on each side, arranged in the form of a double cross. Each of the transepts was iii feet in width and 386 feet in length and 29 feet high to the square. They were located to best serve economicaUy the purpose intended. In one of them was placed the machinery for the converting department, one was used for a train of rolls for making light rails for mining and light tramway purposes, the other two were intended for rolUng merchant steel. Near one end of the main building the converting department was located, in Une with the transept that contained the ma¬ cliinery for operating the converting plant. This machin¬ ery consisted of blowing engines and lugh-pressure pumps for working the cranes and handling the converters. We put in four eight-ton converters. The object in putting in the four converters was to practicaUy do away with mght and Sunday repair work, which is expensive and a great nuisance. Back of the converters were placed the cupolas, eight for melting the iron, and two for melting the spiegel- eisen, A space back of the cupola was arranged for the mixing of the refractory material for making the converter
