Depletion of iron ore in the Nation's large deposits has directed attention to other sources. One of these is the titaniferous iron ore of the Iron Mountain, Wyo., area. Tests were made to determine the feasibility of smelting this ore, which contains about 20 percent titanium dioxide (Ti02), in an electric-arc furnace to produce pig iron. Initial tests, which were made in a 30-pound-capacity induction furnace, demonstrated that the iron could be easily reduced to metal and that limestone was a suitable and effective flux. Larger scale tests then were made in a 50-pound-capacity electric-arc furnace to obtain the more detailed information necessary for the planned continuous operation of a still larger arc furnace. The principal facts determined by preliminary batch-smelting studies were that (1) 9 pounds of limestone flux was required for each 100 pounds of ore smelted, (2) expensive coke was not required because coal proved to be a satisfactory reductant (near stoichiometric carbon was optimum), and (3) overreduction, which produced a viscous slag, must be avoided.

Red Hill School was located in the western portion of Broad Run Magisterial District of Loudoun County, on what is now Evergreen Mills Road. During the time covered by this register, Red Hill School was a school for white children. The register includes the names of students and their attendance for six full school terms (1886-1893), and half of an additional term in 1893. It also includes end-of-term statistics and lists of books used. The teachers listed include Minnie Coe (b. 1864), Matilda Rawlings (b. 1815?), Harry C. Fuller (fl. 1880s), Ida Dawson (1871-1964), Rosa B. Young (fl. 1880s), and Laura L. Smith (fl. 1880s).
