Cornish mining engineers travelled around the world for work, carrying regional speech and practical knowledge with them. This migration is offered as an explanation for elements of southern American vernacular that resemble speech from southwest Britain. It also prompts a tentative connection to the aerial-torpedo tension wire. Dr. Clarke recalls that the observer behind the idea was the son of a Cornish mining engineer and suggests that mining machinery for lifting heavy loads may have influenced him. That family connection and its possible technical significance are presented as recollection and speculation.
