Jules-Louis Breton and the members of the High Commission of the Directorate of Inventions attend the testing of two ploughs. The first test shows a plough towed by a Saint-Chamond tank. The second test shows a Saint-Chamond tank whose front has been fitted with two plough systems. The operation of the mechanisms is observed before being implemented in the field.
