iron sent us by parties interested in the works. A hearth was made near the base of the chimney for melting spiegel; and subsequently a small furnace (located at S, Fig. 60) was constructed for melting spiegel when the metal for conversion was taken direct from the blast-furnace.
Continuing our description of the works, Fig. 01 is a view of the machinery in the casting-house as it appeared to a person standing in the "pulpit" (see Fig. 60) and looking toward the converter, V. This converter is represented on a larger scale in sectional elevation

- It was at these works, in the summer of 1865, that Z. S. Durfee made the first attempt to melt pig metal in a cupola for use in the converting vessel. At that time the practice abroad was to melt the metal in a reverberatory furnace. Owing to the small size of the cupola and its distance from the converting vessel, the experiment was not entirely successful; but Mr. Durfee did not abandon his belief in the usefulness of this process. I claim for him the origination of the idea of cupola melting, which has contributed so much to the rapidity and economy of production in the steel-works of the world.
