John Winthrop, Jr., on Indian Corn

In the aftermath of England’s civil wars, farmers and scholars alike were forced to re‑think how the land could feed a nation. The era sparked a restless curiosity about crops unknown to the English palate—turnips, clover, even the humble potato that had transformed Irish agriculture. Figures such as Samuel Hart‑lab and the chemist Robert Boyle gathered questionnaires, sending agents across the world to catalogue soils, planting methods, and any hidden advantages they might reveal. Their work laid the groundwork for a network of inquiry that would soon reach across the Atlantic.

Enter John Winthrop, Jr., a colonial governor with a keen eye for the New World’s bounty. In a 1662 letter to Boyle, he offers a tentative essay on American maize, describing its growth, the way it is ground into bread, and the practical questions that still puzzled him. Listeners are invited into this early scientific exchange, witnessing the excitement and uncertainty of introducing Indian corn to English farms and the broader hopes that a foreign grain might help restore fortunes battered by war.
