How to live: A manual of hygiene for use in the schools of the Philippine islands
“ These foes are harder to fight than those who come openly and slay with the sword. They are more dangerous foes, moreover; for they are about us always, and must be fought daily. Otherwise, they will rob us of health, of comfort, of sight; they will make us the victims of disease which is ugly to look upon and painful to bear. They even take from us life itself, unless we are constantly on guard to fight their great helper, the dirt, which gathers about any neglected spot. ”
