, is 53 cents per cubic yard. The cost of filling, including tamping, may be taken as about one-third that of excavation, or, say, 18 cents per cubic yard.

_Summary_ Excavation, 14,296.2 cu. ft. = 529.5 cu. yd., at 53 cents per cubic yard $280.64 Filling, 802.2 cu. ft. = 29.7 cu. yd., at 18 cents per cubic yard 5.35 ------- Total cost of excavation and filling $285.99

STONEWORK

=3.= The foundation walls are built of rubble masonry to the sill at the grade line, and from this sill to the water-table they are built of ashlar with rubble backing, except those portions behind porches and steps, which are wholly rubble. The estimate for stonework also includes the concrete for footings and cellar floor; the number of cubic feet of concrete required for the footings will be found by referring to the item Excavation for Wall Footings.
