Used in Leadville belong to two styles, both built on the same general principles. The difference between the two kinds is that one has a rectangular and the other a circular cross-section. They are constructed upon the plan set forth in Fig. 44, with the modifications demanded by local peculiarities and the character of the ore. The material used in their construction is:
</p><p>1. Common bricks for erecting the outer walls and dust chambers.<br>
2. Firebricks for lining of furnaces.<br>
3. Cast-iron for the water jackets, etc.<br>
4. Tapping clay.
</p><p>Fig. 42 represents a modern roasting furnace, drawn to scale.
</p><p>The charge is introduced at the flue end, through two penings, shown in cross-section C, D.
</p><p>It is spread over the bed and gradually moved towards the fireplace G, H, which is separated from the working bed by a hollow fire bridge, shown in the plan and cross-section A, B.
</p><p>The furnace has nine working doors on each side. Through the two nearest the fire bridge, shown in section E, F, the roasted ore is raked out.
</p><p>Fig. 43 represents an old fashioned blast furnace, as well as the manner in which the sheet-iron casing is fastened to the supporting columns,etc.
</p><p>Fig. 44 represents a modern water jacket blast furnace of the type used in Freiberg, Saxony, and similar in construction to the furnaces used in Leadville, and elsewhere in the United States.
