_Pasteboard_ (strawboard or juteboard) may be used for the roof.

_Weaving Materials._--Rugs may be made from carpet rags, rug yarns,
rovings, chenille, or jute; towels from crochet cotton; and hammocks from
macrame cord or carpet warp.

_Wood for Furniture._--Bass, white pine, poplar, or other soft wood. Box
tops, if of soft wood, may be made to serve nearly all needs. If possible,
provide thin wood (about 1/4 in. thick) in various widths, from one inch
to six inches, so that only one dimension need be measured. Provide also
thick pieces 1-1/2 in. or 2 in. square for beds and chairs; 1/2 in. square
for table legs.

_Nails_ of various sizes, chiefly inch brads, are needed.

=Tools.=--The tools actually necessary are few. A class can _get along_
with one saw and still do good work, though there will be times when
several saws will facilitate progress. Some tools are needed only for a
short time and sometimes may be borrowed from the homes. It is more
satisfactory to have the school provided with the essential tools whenever
possible. The essential tools include:

_Brace and auger bit_, for boring holes in doors and windows. Needed for a
short time only.

_Compass saw_, for sawing out doors and windows.

_Crosscut saw_, for sawing off lumber. School should own at least one.

_Miter box_, for holding lumber and guiding saw. An old one, good enough
for children's use, will frequently be contributed by a carpenter. The
miter box should be fastened firmly to a low table or box.

_Hammers_, several of medium size.

_Try-square_, a very valuable tool for setting right angles, provided the
teacher and pupils know how to use it.

=Arrangement of Rooms.=--The sort of house a man can build is governed by
his resources and his site. Considering the number of boxes as resources
and the table or shelf on which they are to stand as the site, the same
big factors which enter into any house-building problem control the size
and style of the schoolroom playhouse. What sort of house is desired? What
sort of house can be built from the materials at hand? What sort of
