Bricks, built in hollow walls, are better than any other material. Commence with a stone foundation-the bottom course of which is broader than the stone-work above it-laid in half cement mortar up to the grade line, and then build the brick wall upon that, filling in all the space inclosed by the walls with concrete up to the line of the top of the water-table. Then pave with stones, firmly bedded to form a floor. On the outside, there should be a stone water-table, 8 or 10 inches high, projecting 1 or 2 inches outside of the main walls above, and having the upper surface of the projection beveled off to shed the water. Just above the water-table, it is well to have a course of slate built in the full thickness of the walls, which will prevent any dampness rising up into them from the ground by capillary attraction. Above the water-table, the walls should be built up with a smooth face, and with close, neatly struck joints inside as well as out, so as to present a clean, even surface, which should always be kept painted or washed with a lime or cement wash. Above the wall-plate, the space should be filled in to the under side of the root-boards. The ceilings over the main story should be lathed and plastered; partly for the sake of the neat appearance, partly to keep away cobwebs which infest exposed beams, and partly to prevent foul air rising from the room below, and tainting the hay-loft. The doors and windows inside should be trimmed with architraves, even if the latter be merely strips of the cheapest stuff. It may be desirable to fur out and lath and plaster the walls of a stable; but if this is to be done, it is better to wainscot with wood up to the height of, say 5 feet, and to fill in the space between the walls and the wainscot, as high as practicable, with broken glass and mortar, and then to lath and plaster from the wainscot up to the ceiling. A wooden stable, too, may with advantage be treated in the same way, but the space behind the wainscot being wider, may be packed with bricks and mortar, and made solid in that way.
