#### Introduction

Suppose you saw someone crossing the street, not particularly noticing where he was going. Now suppose that he is about to step into an open manhole. How would you respond? Some people, not the kind we would want to know, might remain silent, hoping to enjoy the spectacle of someone falling in and breaking his leg at the bottom of the city sewer. Others might wish to help, but are too timid, afraid that they may be wrong, or that they will offend the careless pedestrian. After all, nobody likes to be told that they are making a mistake.

Yet, I hope that you would be the kind of person who would recognize the danger and think enough of a fellow citizen’s welfare that you would shout out a warning and point out the danger. If he stubbornly refused to listen and fell in anyway, at least you could sleep that night. It is in this spirit of kindly warning that I have written this pamphlet. I hope that you will take just a minute or two to read on with an open mind.
