Fig. 10. This Figure shows how the covings are to be placed when the front of the covings (a and b) do not come so far forward as the front of the opening of the Fire-place, or the jambs (A and B). See page 348.

Fig. 11. This Figure shows how the width and obliquity of the covings are to be accommodated to the width of the back of a Fire-place, in cases where it is necessary to make the back very wide. See page 349.

Fig. 12. This Figure shows how an instrument called a bevel (m n), useful in laying out the work, in altering Chimney Fire-places, may be constructed. See page 349.

Fig. 13. This shows how, when the breast of a Chimney (d) is too high, it may be brought down by means of a wall (h) placed under the mantle, and a coating of plaster, which in this Figure is represented by the part marked by dots. See page 351.
