1 July 1806
During the course of August the turning of the lobby arches will render the progress of the freestone work unequal, but it is highly probable that on the
1st. of Septr. All the freestone work will be finished & be ready to receive the roof.
In the meantime,—on the
1st. of July,—All the sashes & frames of the Office Story will be put in, & the grounds for Plaistering put up.—
10th. The Plaisterers will begin to plaister the South West rooms, & proceed regularly thro’ the West range of Apartments.—
1st. The Lobby on the West side will be covered
15th. The Timber of the roof on the West side will be in great forwardness, and some of it upon the roof.
The East lobby will be covered.—
Sept 2d. Begin to set up the ribs of the dome
15th. Begin to cover the dome with Iron.
Octr. 1st. Have the whole roof covered
At this period the actual appearance of the building must determine the sort of finish for this season which it shall receive. For if on the 1st. of Octr. the roof is covered in there can be no doubt but that the house of Rep. in congress will hold their session in their new Hall.
I hope the we may be one month forward on than I have stated. Advertisements for stone cutters in Baltimore, New York, & Philadelphia are sent forward, & generous wages offered. Of other artisans we have no want.
