tions, but if
such work shall prove upon inspection to have been well done the
contractor may make a charge of the amount which would have been allowed
for that part of the work had it passed inspection.

When the work is completed it must pass the final inspection of the
supervisor, or such person as the Secretary of the Interior may
designate for the purpose.

1. CLEARING OUT THE DEBRIS

The debris now filling up the interior is to be removed down to the
floor level, or the original ground level. The debris covering an area
measuring 10 feet from the exterior walls of the building in every
direction is also to be removed. This work is to be carried on in
conjunction with the underpinning of the walls, and is to be dependent
upon the progress of the latter, the work being done as required by the
person holding the contract for the underpinning. All proper precautions
must be observed during the progress of the work to prevent any injury
to the building, the walls being properly braced and supported before
excavation is commenced. The contractor will be held responsible for any
injury to the building. Any objects found of archeologic or other value
properly belong to the United States and must be deposited in the
National Museum. The material removed from the building and from the
area about it is to be removed to a proper distance, not less than 100
yards from the building. Proper drainage channels must be provided to
keep the excavated area permanently clear of water.

2. UNDERPINNING WALLS

The walls where eroded at the ground level are to be underpinned with
hard-burned brick, laid in good cement mortar and extending to a depth
of at least 12 inches below the original ground level. This work must be
carried on gradually and very carefully in conjunction with the clearing
out of the debris. The under surfaces of the overhanging walls must be
carefully trimmed to afford solid horizontal bearings against the
brickwork. The face of the brickwork is to be set back at least 1 inch
and not more than 2 inches from the face of the wall, and the brickwork
is to be plastered with a coating of cement mortar, 1 to 2 inches thick,
bringing it out flush with the outer wall.

3. FILLING IN OPENINGS

The broken-out lintels of openings are to be replaced by wooden lintels
composed of squared lumber, 2 by 4 inches in size, laid side by side
across nearly the whole thickness of the walls, with not more than 1
inch space betwee
