Head Quarters Morristown 13th May 1780.
Sir James Jay has requested the assistance of a few Artificers for a day or two to erect a small Elaboratory. As he purposes making some experiments which may be of public utility and has already furnished me with some Chymical preparations from which I have derived considerable advantages I think it proper to gratify him. You will therefore be pleased to furnish him with the necessary hands. And should a few Boards or such matters be wanting to compleat the building, which is to be of Logs, you will also procure them, if it be in your power. I wish you and Mrs Hay a pleasant Journey and am, Dear Sir, &c.
