    The Governor of Overijssel Province wrote the Mayor of Ommen saying that he was told that Rev. Albertus C. Van Raalte was arrested and incarcerated in Ommen as well as receiving the report of the disorder in the town. The Governor ordered the Mayor to make sure that disorder cease and be dealt with and summons given to the perpetrators of the disorder.https://digitalcommons.hope.edu/vrp_1830s/1044/thumbnail.jp

    Letter from The Mayor and Councilmen of Ommen to the Governor of the Province

    The Mayor and Councilmen of Ommen sent a communication to the Governor of the Province saying that those persons who petitioned the Governor not to send a military detachment were without adequate grounds for complaint. Those persons who have ill members of the family will not have to billet soldiers. Those who do are paid thirty five cents a person per day for expenses. The Mayor and Council would like to have the military detachment certainly through 5 December when an annual market is held. The plenteous use of strong liquor then may give rise to unrest.https://digitalcommons.hope.edu/vrp_1830s/1049/thumbnail.jp

    Nineteenth century land-use, watershed erosion, and sediment yield in southern Appalachia

    The purpose of this research was to gain insight into the anthropogenic forcing of geomorphic systems, specifically how nineteenth century land-use changes impacted watershed hydrologic, upland erosional, and sediment delivery subsystems of Southern Appalachian headwater catchments. Identification and analysis of the timing and rate of change in these subsystems, and the reestablishment of presettlement conditions, were used to address landscape sensitivity and watershed inheritance issues in a region undergoing population expansion and development. Archival research was used to reconstruct concurrent land-use changes in the catchments of two nineteenth century water-powered mills. Changes in the physical properties of mill pond sediments including, organic content, particle size distribution, and magnetic susceptibility, were used to interpret trends in sediment source during the span of mill operation. Interpolation of augering and coring data was used to determine mill pond sediment mass and pond capacity. Hillslope hydrologic change occurred almost immediately following land conversion. Upland erosion began with the removal of A-horizon fines, and progressed with the removal of A-horizon coarse particulates, and then B-horizon particulates. Change from one source category to another was punctuated by high flow events signifying an integration of human activity and climate in the changing of system boundary conditions. Late nineteenth century sediment yield in Southern Appalachia was almost as high as that reported for the adjoining Piedmont although only 25 percent of highland watersheds were converted to agriculture. However, sediment delivery ratios were relatively low indicating a more complicated relationship between hillslope-channel connectivity and soil erosion. In reforested watersheds, both the hydrological and erosional subsystems reverted to presettlement conditions within a few years but may have taken up to one hundred years for sediment yield rates to return to presettlement conditions. Finally, the sediment trapped behind nineteenth century dams has served as a significant source of ecologically damaging washload to highland streams during the twentieth century
