How to use this document

Who it's for: groups camping, living rough or running a camp for days or weeks without running water or toilets.

How to read it: Chapter 3, Personal hygiene, ends with a short list of rules for avoiding illness in the field. Chapters 4 to 6 cover field water supply, food sanitation and waste disposal, from the cat-hole to the straddle trench latrine. Chapters 7 to 16 deal with insects, ticks, venomous animals, rodents and other carriers of disease one at a time, and Chapter 17 covers heat and cold. Read the pest chapters for the methods, not the chemicals.

Read with careWritten in 1970 and long superseded. Its pest-control chapters recommend insecticides that are now banned or restricted, including DDT (banned in the US since 1972). Read those chapters for the principles only, never the chemicals.
