From Jan H. C. Heineken
Philadelphia, 10 Nov. 1791. Having asked Frederick A. Muhlenberg to introduce to TJ “Mr. Halbach of Remschua,” who has come to America to see if his house’s “very extensive manufactory of Ironmongery, arms &c.” can supply the American market, he gives assurances that his sole view in this is to encourage intercourse between the United Netherlands and the United States.
