1. Joshua Humphreys Ledger D., 1766-1777, HSP. Another bill, for building the Pennsylvania Galley Washington, is in the same ledger. As the dimensions and quantities of material differs but slightly, and the workmen employed were the same as for the Experiment, it seems needless to give the detailed bill. It was delivered on the same day, September 20, as the Experiment's bill, but was about seventy-five pounds greater, £355..4..2.
