1. Locate the privy inconspicuously and detached from the dwelling.

2. Make the receptacle or vault small, shallow, easy of access, and

water-tight.

3. Clean out the vault often. Do not wait until excrement has accumulated

and decomposition is sufficiently advanced to cause strong and foul odors.

4. Sprinkle into the vault daily loose dry soil, ashes, lime, sawdust,

ground gypsum (land plaster), or powdered peat or charcoal. These will

absorb liquid and odor, though they may not destroy disease germs.

5. Make the privy house rain-proof; ventilate it thoroughly, and screen

all openings.
