APPENDIX IV 
Directions for Building a Sanitary Privy* 
I N order to put the construction of a sanitary privy 
for the home within the carpentering abilities of 
boys, a practical carpenter has been requested to con¬ 
struct models to conform to the general ideas expressed 
in this article, and to furnish estimates of the amount 
of lumber, hardware, and wire screening required. 
Drawings of these models have been made during the 
process of construction (Figs. 36, 37) and in completed 
condition (Figs. 38, 39). The carpenter was requested 
to hold constantly in mind two points, namely, (1) 
economy and (2) simplicity of construction. It is be¬ 
lieved that any fourteen-year-old schoolboy of average 
intelligence and mechanical ingenuity can, by follow¬ 
ing these plans, build a sanitary privy for his home at 
an expense for building materials, exclusive of recep¬ 
tacle, of five to ten dollars, according to locality. It is 
further believed that the plans submitted cover the es¬ 
sential points to be considered. They can be elaborated 
to suit the individual taste of persons who prefer a 
more elegant and more expensive structure. For in¬ 
stance, the roof can have a double instead of a single 
slant, and can be shingled; the sides, front, and back 
can be clapboarded or they can be shingled. Instead
