    Plastering. All of the walls and ceilings will be lathed and will receive two coats of plaster, hard finished in plaster of Paris. The browning coat will be put on with good mortar composed of thoroughly slaked lime, clean sharp sand, and a plentiful supply of well-beaten long winter ox-hair. The finishing coat will be com- posed of lime, putty, and plaster of Paris exclusively, and will be well trowelled. All surfaces will be straight, plumb, and out of winding; angles and arrises of chimneys will be straight and plumb. The ventilator duct in wards will be lathed and plastered. Tin Work. The roofs of verandas will be tinned with best roofing tin, laid on tar or felt paper, with standing grooves, and well secured to the sheathing by a sufficient number of flaps. Sunk or valley gutters to be put to all roofs, with sufficient fall to down spouts. Conductors 3 inches in diameter will convey the water to cistern connections. Tin valleys and flashings, wherever they are required, to be furnished and put in place. Scuttles to be covered wholly with tin. A 20 by 8 inch galvanized iron ventilating pipe for ventilation of ward, running between joists, opening under floor of veranda, having 2 regulating registers at ends of pipe. In the centre of this pipe, on the upper surface, should be an opening 20 inches square corresponding with a similar opening in the floor of the ward, over which a jacketed stove may be placed. Where it is impossible to obtain the galvanized iron, wood may be used. In climates so cold that it is necessary to use two stoves, there will be two ventilating pipes, each 10 by 12 inches, arranged in the same way in connection with each stove. A force pump at sunk cistern will be provided for pumping water into cistern in roof. A 11-inch pipe will go from sunk cistern to cistern in roof. Painting. The entire wood work usually painted inside and out will receive two coats pure white lead and pure boiled linseed oil. All knots and sap spots will be killed, and nail holes puttied. The second coat will be a good covering coat. The floors of the verandas will have three coats pure boiled linseed oil and yellow ochre. All tin roofs, gutters, conductors, and flashings will be painted two coats metallic paint.
