To put the stairs together after all the pieces have been prepared, place the bottom riser in place and fasten it in with glue and a wedge; then toe-nail it into the stringer from the back. Now fasten the outside stringer to the riser, bracing it into position; then fit the second riser and the first tread into place; then fasten with glue and wedges, and toe-nail the riser and the tread to the stringer. The treads will be nailed to the risers so as to unite the work firmly together.
Another method of fastening the riser to the tread is to groove the front edge of the tread and have a tongue on the riser, an illustration of which is shown in [Fig. 123].

To decorate stairways mouldings are used; generally a cove moulding is fastened under the front and the end of the tread, an illustration of which is shown at [Fig. 124]. The hammer is used in this problem; it is hardly necessary to explain its use.

Toe-nailing is the driving of nails obliquely in order to fasten two pieces that may be at an angle to each other, as illustrated by [Fig. 125].
