Practical sanitation; a handbook for sanitary inspectors and others;with apxon Sanitary law, by Herbert Manley . orre-sponds with an ordinary area, except that it is covered, and isonly sufficiently wide to keep the damp earth from touching thewall. Another plan (Fig. 98) that answers very well, is to buildthat portion of the wall which is below the ground level,hollow, and in this case it is necessary to insert two damp-proofcourses, the one extending across the whole width of the wall 176 PRACTICAL SANITATION. below the basement floor, and the other across the outer sectionof the hollow wall a little above the ground level. The accom-panying sketches will assist in making the above descriptionclear. No matter which plan is adopted, it is necessary to providedrainage from the bottom of the area or cavity, and, both in thecase of the dry area and the hollow wall, ample openings mustbe provided for ventilation. For this reason, in order to avoid aspace in which dirt may accumulate, a better plan is to fill thecavity with asphalt, which would entirely prevent the penetra-tion of damp. Ground level. Fig. 97. Fig. 98. Impervious walls above the ground level are also of importance,otherwise driving rain will penetrate into them, especially inthe case of houses in exposed situations, and during long periodsof rain. Walls may be rendered practically waterproof by coating themwith good Portland cement. Slates or tiles fastened to battenson the face of the wall, will also answer the purpose, althoughthe former are unsightly, as indeed are the latter, unless in theoriginal design it was intended to construct tiled walls. Rough-casting, which consists of a coating of good mortar, on whichshingle and small pieces of flint are sprinkled, answers thepurpose when the work is well done, and it does not necessarilydetract from the appearance of the house. Pitch or paint, ifregularly renewed, will also protect the walls from damp, butboth are unsightly, and the latter is costly. HOUS
