Sir. We received your fav. of Aug. 1st with the samples of Salt, (by Mr. Jones) which gives us much satisfaction; as they afford a flattering prospect of ample supplies, in future, of that necessary Article. We recommend to you to proceed, with all possible Expedition, to the Completion of your evaporating scheme; but as the advanced State of the Season will probably prevent you from doing much in that way shortly, we approve of your making the Experiment by boyling.—

We shall be glad at all times to hear how you proceed and are.
