Letter from George Washington to George Plater, dated October 25, 1784, proposing six different water routes from Detroit to the East, as a means of diverting the commerce of the West from the British and Spanish. Written to a leading citizen of Maryland, this letter is almost identical with his letter of October 10, 1784 to Benjamin Harrison, governor of Virginia, and was part of the promotional campaign of the Potomac Navigation Company, of which Washington became the first president.
