I recently picked up this stereoview showing young inmates of the Michigan State Reform School engaged in military drill, likely dating between 1876-1882. Located in Lansing, MI, the Reform School was founded in 1855 as a state-run penal institution for minors and included a school, farm, and workshops where the inmates were employed manufacturing clothing, cigars, and furniture. While many of the boys were convicted of crimes such as larceny and burglary, many others were vagrants left homeless by the deaths of parents or because they had been compelled to flee abusive circumstances.
Military drill, while exercised there for years, became a daily part of the institution's educational program starting in 1876, when "serviceable state arms" were first authorized to be issued to the young inmates. The school hired Civil War veterans to serve as drill masters, and outfitted the boys in "a very neat military uniform of dark blue jacket and cap , with gray pantaloons" which were made by the inmates themselves. The superintendent claimed that drilling benefitted the boys by giving them "a manly bearing and a correct idea of discipline..."
The institution closed in 1972 and most of the buildings were demolished within the following year. 60 inmates lay buried in unmarked graves at a local cemetery, but in 2019 an effort by The Friends of Lansing's Historic Cemeteries sought to raise funds in order to add markers.
