not go over the roof with the ladders after it is finished. The life of a shingle roof can be more than trebled if the shingles are dipped into properly prepared paint before being laid.

In dipping the shingles, they should be dipped at least eleven inches. This will allow 4+12 inches to the weather and 6+12 inches for the under lap. Never dip damp shingles; break the band around the bunch and spread them out to allow of drying before dipping or applying the paint. For dipping shingles, use paint of the proper consistency for finishing coat, reduced with not less than 50 per cent raw linseed oil. When the shingles are laid, finish with one coat of paint of a finishing coat consistency. Remember the roof is subjected to very severe weather wear and soon shows defective work.

The Paint. The paint for the roof should be of good material. A mistake which is often made is that a very cheap mixture will do for shingles. Have the priming coat thin and enough of it mixed at one time to cover the entire roof. Keep the paint uniform while working and avoid having heavy laps or spots, as they will soon show through the second coat and make an ugly looking job. The second coat should be of good consistency and be well brushed out, using care to keep from applying the paint unevenly.

Foundation and Flues. Do not paint damp brick. Oil paint is the best size for brick. If the flues run from the foundation to the roof on the outside of the building and are to be painted a different color from the house or given a ground color of Venetian red, they should be painted before the siding is painted, especially the first coat, as it is very hard to keep paint from splashing over the siding in working on rough brick. Where flues are to be penciled and flat brick used, the flat color can be very easily applied after the body color has been applied. Never apply less than three coats on brick. If after the second coat has
