The origin of Shurtleff College was the "Theological and High School" commonly known as the Rock Spring Seminary, established (1827) by John M. Peck, D. D. The latter was closed in 1831, and opened again the following year at Alton, under the name of Alton Seminary. In March, 1832, the state legislature incorporated the institution as "Alton College of Illinois." For religious reasons the charter was not accepted until 1835, when the terms of incorporation had been made more favorable. In January, 1836, the charter was amended, changing its title to Shurtleff College, in honor of Benjamin Shurtleff, M. D., who had donated ten thousand dollars to the institution. Although from the first emphasizing religious instruction, a theological department was not organized until 1863. The school is still under Baptist influence.--ED. [137] Hillsboro, the seat of Montgomery County, twenty-eight miles from Vandalia, was platted in 1823.--ED. [138] In his description of the barrens, Flagg follows quite closely J. M. Peck, _Gazetteer of Illinois_ (Jacksonville, 1837), pp. 11, 12. The term barrens, according to the _Century Dictionary_, is "a tract or region of more or less unproductive land partly or entirely treeless. The term is best known in the United States as the name of a district in Kentucky, 'The Barrens,' underlaid by the subcarboniferous limestone, but possessing a fertile soil, which was nearly or quite treeless when that state began to be settled by the whites, but which at present where not cultivated, is partly covered with trees." See a good description in our volume iii, pp. 217-224.--ED. [139] According to the War Department's _List of Military Forts, etc., established in the United States from its Earliest settlement to the present time_ (Washington, 1902), a Fort Gaines was at one time located at Gainesville, Alachua County, Florida. The town is now the seat of East Florida Seminary, a military school. Among the numerous lakes in the vicinity, Alachua, the largest, occupies what was formerly Payne's Prairie. Through this prairie a stream issuing from Newman's Lake flowed to a point near the middle of the district, where it suddenly fell into an unfathomed abyss named by the Indians Alachua (the bottomless pit). The whites gave this name to the county, and called the abyss "Big Sink." This place became a favorite pleasure resort until 1875, when the sink refused longer to receive the water, and Payne's Prairie, formerly a rich grazing land, was turned into a lake. Numerous tales connected with Big Sink were circulated, and it seems probable that Flagg is referring to this locality.--ED.
