376 Sloan's Architectural Review and Builders' Journal. [Dec, SPECIFICATION OF THE Workmanship and the Materials required in the Erection and Construction of a City Dwelling in the City of Philadelphia. General Dimensions. The Building is twenty-five (25) feet front by sixty-three (63) feet deep, and three stones high, with abasement, and attic rooms within the roof, lighted with dormer windows on the front and rear, and a window in each gable. Height of Stories. The basement will be nine (9) feet ; the first story fourteen (14) feet four and a- half (4^) inches ; the second thirteen (13) feet one and a-half (1^) inches ; and the third twelve (12) feet ten and a-half (10^) inches, all from floor to floor ; and the attic will be nine (9) feet in the clear. For the internal arrangement of the several stories, reference is to be had to the plans upon which all the dimen- sions are figured. Excavations. The basement will be excavated to the required depth to make the story nine (9) feet in the clear, when finished. The area on the rear, which is eight (8) feet wide, will be six (6) inches deeper than the basement floor. All trenches for foundations or footings, cess-pools and drains, are to be dug out to their re- quired depths. The earth must all be carted from the premises, and the grounds cleared up of all rubbish and refuse material at the completion of the building, and the whole left in a condition ready for occu- pancy. Masonry, The walls of the cellar will be con- structed with the best quality of quarry building-stone ; the footing-course to be through stone, well and solidly bedded in mortar; — all stone to be properly hammered and laid close and level, well banded and flushed in. The exterior face of all the stone walls that are in sight must be property faced and painted. The mortar for the masonry will be composed of clean sharp sand and fresh lime ; and the inner facings of all the walls will be dashed flush with the same material. All those walls which come into contact with the ground are to be coated on the outside with a full coat of hydraulic cement. Concrete. The whole of the basement and cellar floor is to be coated over with a bed of concrete, composed of broken stones and liquid cement, laid four (4) inches thick, and coated over the top to a smooth surface. The sleepers for the kitchen floor will be bedded in the concrete, eighteen (18) inches apart, and projecting about a half (J) inch above the surface. Cut-Stone. The entire front will be cut-stone, and done with the best quality close fine- grained stone, of an uniform color, dressed and set in the best and most workmanlike manner, agreeably to the design and working drawings ; and all to be pointed and cleansed off, and also polished, except what is hereafter men- tioned.
