From the Bury & Norwich Post of 15th May 1816:
Thursday last a thrashing-machine was taken into the Market-place at Clare, and burnt by the populace.From the (later) Suffolk Chronicle of 25th May 1816:
The statement of a threshing machine having been burnt in the market-place, at Clare, we understand, was incorrect. A part of the machine only was destroyed, in a field some distance from the town.The incident was reported to the Home Office by a General Elwes on 23rd May 1816, stating it was the 'destruction of a Threshing Machine by fire', although he says it took place on the 8th May.
Elwes' letter can be found at HO 42/150.
