In a letter to St. John de Crevecoeur, dated 25 August 1789, Tardiveau discusses his activities in Kentucky, events occurring there, the state of agriculture, manufacturing, and trade (specifically mentions Kentucky trading with the Spanish settlements on the Mississippi) the climate of Kentucky versus that of Cumberland (Tennessee) for growing certain crops, and the economic future of Kentucky and the United State in general. He also mentions frequent Native American activity along the Green River and southward. He states how surprised his brother (Pierre Tardiveau) and other friends were upon his and a fellow travelers return to Danville after a trip to Cumberland; they were three weeks overdue and those in Danville assumed they had been killed by the Indigenous peoples.
