Now to show you how we control our people, I have prepared some charts to show you the control we have set up over people. It is known as the warden service. It is a very simple service and it is a service where the operators stay at home. The basis of our warden service is on the multiples of 10 - 10 beats to a post, 10 posts to a district, and as many districts as you need in a zone. The chief warden is at the control center with a sone warden at each of the zone control centers, a warden headquarters for each district, and a small headquarters for each post. The warden should be someone who lives on that beat and who is highly respected, whose people have confidence in him. There are many things he should de prebomb. He should make a map of his beat. He should know exactly where the houses are. He should know where the fire hydrants are. He should know if trees are apt to blow over and block a street. He should know if there are any people seriously ill so if he has to evacuatge the area they can be moved. He shoule know where the shelter is for each one of theese houses because if it is an area of heavy desteruction, that information is most important. He must know aht the condtions are in each area as to first aid; how many people in the area have had first aid training and know what to do. (Huebner, Civil Defense, 1953, p. 28)
