Chris Raible, scholar of the 1837 rebellion, was telling me once about Rebellion boxes -- hand-carved wooden boxes created by prisoners of the 1837 Canadian rebellions as passtimes, as mementos, as heirlooms.
Now Chris and the York Pioneer and Historical Society are launching his book From Hands Now Striving to be Free: an inventory of boxes crafted by 1837 Rebellion prisoners on April 26. Details here. No less than 94 of them have been identified.
