For outside wood work, paint made from white lead ground in linseed oil is most used. If the oil is raw, or unboiled, dryer is added; if boiled, no dryer is necessary. Not less than four coats should be applied -- five are better.

Paint, ready mixed, put up in cans or kegs, may be procured from manufacturers or dealers. These paints have to be thinned by adding 1 pint of oil to about 2.5 lbs. of paint. When thinned, 1 lb. will cover about 2 square yards of first-coat, 3 yards of second, and 4 yards of each subsequent coat; or 1 3/8 lbs. to the square yard will be required for 4 coats, and 1 5/8 lbs. for 5 coats.

For inside work, either white lead or oxide of zinc is used, and for good work 4 coats are necessary.

For iron exposed to the weather, metallic paints, such as yellow and red iron ochres or brown hematite ore, finely pulverized and mixed with oil or dryer, are best.

For iron subject to the action of water, red lead is best.

Plastered walls should stand a year before painting.

Painting is measured by the square yard, girding every part of the work that is covered by paint and allowing an addition to the actual surface for the difficulty of covering deep quirk of moldings and for " cutting in " as in sash and shelving, or where there is a change of color, on same work.

Painter's Putty.

Spanish whiting, pulverized, 80.6 and Boiled oil, 20.4

Made into a stiff paste. If not intended for immediate use, raw oil should be used.

One pound of putty for stopping every 20 yards.

Glazier's Putty.

Whiting, 70 lbs.; boiled oil, 30 lbs.; water, 2 galls. Mix. If too thin, add more whiting; if too thick, add more oil.

To Soften Putty.

To remove old putty from broken windows, dip a small brush in nitro-muriatic acid or caustic soda (concentrated lye), and with it anoint or paint over the dry putty that adheres to the broken glass and frames of your windows; after an hour's interval the putty will have become so soft as to be easily removable.
