In all places where the roof meets a vertical surface, three cornered strips 1'- inches by 1 inches are to be nailed, and the canvas is to be carried up over them and S inches on the vertical wall. If such wall is of masonry, there will be a 1i inch by 2' inch dressed strip bolted by expansion bolts set 3 feet apart under the projecting ledge of brick; and canvas is to be tacked to the under side of this strip as at other places.
After the entire roof is covered and the canvas swept clean, it is to be soaked with water, and, when thoroughly wet, is to be rubbed full of stiff paint composed of white lead and raw oil in proportions of 100 pounds of lead to 3' gallons of oil. After this is dry and the surface hard, and not less than five days after the first application, the roof and all exposed surfaces of wood strips in connection there with are to have two coats of white lead and oil paint.
Tile. The steep portions of the roof are to be covered with red tile burned from a tough clay; and all nails or wire necessary to secure them permanently to the roof are to be of copper. If wire is used, the gauge is to be not less than No. 12; if nails, the gauge is to be not less than No. 8.
All joints are to be so close that there will be no necessity for water proof paper below, or for cement, except at the hips.
All valleys are to be open, and flashed with 14-ounce copper, which must extend not less than S inches under the tile at each side.
Gutters and Conductors. All gutters and exterior conductor pipes will be of 1C-ounce copper; and where they join the soil pipe system, they arc to be soldered to cast brass thimbles, which are to be calked into the I_:on piping with pig lead.
Plastering. There will be no plastering in basement; but all the walls above are to be finished with 3-coat work. All brick walls are furred with terra-cotta, on which the plaster is to be placed. All other surfaces are to be lathed with pine or spruce lath only partially seasoned; and wherever these lathed partitions and the brickwork of chimneys or the terra-cotta adjoin, expanded-metal or wire-mesh lath are to be placed, extending S inches onto each side; and, as each coat of plaster is placed, all corners arc to be cut through from floor to ceiling.
All plasterers' material is to be freshly burned stone lime, slaked at least two weeks before mixing with sand; and to contain hair of the ordinary quality sold for plastering purposes, and sand clean and sharp. The mixing is to be done just prior to its use, and is to be thorough. The hair is to be soaked so as to separate it from matting, and enough used, and so mixed that it will not be possible to find any small portions of the mortar in which the hair is not visible.
The first coat is to be mixed very rich with lime, using not more than four volumes of sand to one of unslaked lime; and is to be scratched.
The second is to be a thin coat, in which six volumes of sand may be used to one part of unslaked lime; and this is not to be applied before the first coat is dry and hard.
The last coat in all cases will he white; hard finish of lime putty gauged with plaster of Paris. This is to be applied in not less than five days after the first coats appear dry and hard.
The first two coats are to go to the floor back of all base-boards and wainscot, and be brought up to all grounds.
When completed, the work is to be straight and free from dis colorations, hair cracks, or lime pits.
Paint. All exterior woodwork is to be primed as soon as in place, with raw linseed oil and a very small amount of yellow ocher; and later to have two additional coats of raw linseed and white lead paint mixed in the proportion of 100 pounds of lead to 5 gallons of oil, colored with such pigments as will produce the single color desired, and having no more drier in each coat than is necessary to insure its drying within 1S hours.
All pine woodwork throughout the house, including floors, will have one coat of white shellac and three coats of paint, mixed as above and of the colors selected by the Architect. There will be one color only in each room for finish, and one for floors.
All hardwood except floors is to be filled with a mineral filler, and to have three coats of varnish, the last two rubbed to a dull sur face. The varnish is to be of a brand covered by an affidavit from the manufacturers that it contains no rosin or petroleum products and that it contains at least 17 per cent of copal gums. Also, the varnish must be of such character that a film on glass will not dry in less than 48 hours; and when dry, the film is not to be brittle. Four days must elapse between the application of each coat of varnish and the succeeding coat.
All hardwood floors, treads, and risers are to have one coat of hot raw linseed oil and two additional coats of cold raw linseed oil, three days to intervene between each coat and the next.
Glass. All glass is to be at least k inch thick and free from all smoke, bubbles, or wavy lines. It is to be set in the sash after priming with white lead, back-puttied, and fastened with points not over 6 inches apart and full-puttied.
