ON ENTERING a building, almost the first thing that meets

the eye is the staircase and unconsciously it is made to serve

as an indicator of the quality of the architecture. If the design

is poor or the construction faulty, this flaw immediately gives

the visitor a bad impression of the whole building. Furthermore,

stairbuilding is a rather difficult subject and the principles

involved are very little understood, which is evidenced by

the fact that the layouts as furnished by architects in their

plans are often improperly done.

Probably more mistakes occur in connection with the stairway

of a building than with any other construction feature. It

is with the idea, therefore, of giving a complete though simple

presentation of the construction methods as 'applied to standard

design of staircases, that this book has been prepared.

The article discusses straight and winding stairs, stairs

with well hole, layouts for curved turns, the proper proportions

of rise and width of tread, the design of hand railings and many

other problems, the solution of which will be found very useful.

Coupled with this article is a most instructive section on

the Steel Square, containing many applications of this useful

instrument to roof and other types of construction.
