The powder should have been ordered there, and we understand you have a considerable supply; please furnish four and a half tons for the purpose to Messrs. William Lux, Samuel Purviance, and David Stewart. We will repay you in kind or supply more if necessary. Signed by Franklin, Josiah Bartlett, Richard Henry Lee, and Robert Morris.>
