Power changing state, as a dated sequence: water (1831/32), steam (by 1907, on the farms), current (1898/1900, at the power house)

The three states of power on this ground can now be laid in one dated, located sequence: Water, 1831 or '32: the first sawmill on Baugo Creek, worked by one dam and one race extended to serve both mills (Chapman, pp. 789–790) — the seat's power from the settlement's first years into the flouring era, still the directory's power in 1884–85, when Polk lists Bancroft's saw and flour mill and Mandlin's saw mill. The first mill's own account conflict (DF-9) stands as printed in this section's item 1 — Chapman (1831/32, builder unnamed; second mill Zelotes Bancroft's; 1856 mill the brothers' jointly), Goodspeed 1893 (Zelotes purchasing the original mill; his father William building the 1856 grist and flouring mill), the 1875 atlas (Z. Bancroft settled 1834), and the town history's Ireland version (William Ireland, 1833, dam and bridge) — unreconciled, and nothing in the power sequence depends on which strand is true, because every strand runs on the same dammed creek. Steam, on the farms, by 1907: Edwin C. Laidlaw of Penn Township "operated one of the first steam threshers in St. Joseph county" (Howard, vol. 2, pp. 927–928) — steam's first documented work on this ground was not in a mill but in the fields, threshing the grain the mills had ground; Howard gives no year, and the transition is dated only to his 1907 volume's strength. The steam locomotive had of course crossed the town since 4 October 1851, but that is the railroad's power, carried in the trains leg, not a works transition on this ground. Current, 1898/1900: the interurban put a power house in the town — Howard records that the South Bend–Goshen line of the Indiana Railway Company was built 1899–1900 and "built a power house at Osceola" (Howard, pp. 310–311), while the electric line's own literature (CERA, Marlette's chronology) dates the opening of the Mishawaka–Elkhart section through Osceola to 12 December 1898; the two datings print unmerged, as Transportation already carries them. The power house made Osceola a generating seat for the corridor's cars, a regular station at mile 10.1. The electric age on this ground ends with the line: interurban service ended 1 June 1934. Water to steam to current is therefore this ground's sequence whole — creek power for the mills, portable steam for the harvest, generated current for the railway — each transition dated and located at the strength its source carries.
