Wooden Steps are lighter than those of stone, and do not require such strong supports. They are also more elastic, and do not become so smooth under wear as to be dangerous.

On the other hand, they are subject to decay, they may be more rapidly destroyed in case of a fire, and may thus cut off all exit from the upper floors.

N.B. - The handrails are shown in the elevations in order to make the direction of the steps more plainly evident; but they are omitted in the plans for fear of rendering them obscure. The skirtings are also omitted from the plans. The plaster of the wall is also omitted from both plans and sections of the figures on a small scale.
