The cavity may then be filled, using Portland cement and sand (1 to 3) well tamped in, the cement being put in to form blocks about 12 inches high and separated by tarred roofing paper. The face of the cement should be trimmed back to the level of the cambium. Instead of filling the cavity with cement, a mixture of dry sawdust and asphaltum, 3 or 4 parts to 1, may be used, with the advantage of

Metal coverings of tin or zinc are sometimes used, but in general are not so desirable. Shallow cavities are merely
