to remedy, all hut four such systems
in the State have l>een eliminated.
There are now 5,931 box-can privies in
service.
Concrete Vault Primes
In the extra cantonment zone area
of Fort Bragg, in and around Fayetteville,
there were installed about eleven

in service. Eighty-two per cent (82%)
of all the privies under the jurisdiction
of the State law are pits and the ratio
is rapidly increasing. See Fig. 3 for
"distribution of improved privies by
types."
