Payroll for laborers June 1795

The primary job of laborers in 1795 was tending masons. That year, rather then continue paying days wages to masons, the commissioners made piece-work contracts with a crew of masons on condition that the commissioners provide laborers. Cornelius McDermot Roe, the Irish mason in charge, had been an indentured servant for George Washington at Mount Vernon, and preferred using slave laborers. So I think most of the slaves the commissioners hired that year were assigned to the piece-work masons, for whom no payrolls were kept or at least I haven't found them, which explains why there are so few hired slave laborers on the lists of laborers kept in 1795.
