To size and varnish the paper of a hall and staircase, dissolve 7 lb. of size in 3 gal. of boiling water. When cold it will be of the consistency of a weak jelly. Apply this to the paper with a double-knot distemper brush, being careful to go over every bit of the paper. Twelve hours after, apply a second coat of size. Twenty-four hours after the second coat has been applied the paper will be ready for varnishing. A good paper varnish may be made by well mixing 1/2 gal. of pale oak varnish, 1/2 gal. of turpentine, and 1/2 pt. of raw oil. If the weather is frosty, the staircase and hall should be heated to about 6t)° F. If this is not practicable, wait until the frost disappears. Spi'ead the varnish with a hog's-hair varnish brush, commencing at the top, and working evenly downwards. A second coat of varnish six months after the first has been applied would make a first-class job.
