The Town Council went almost crazy on the subject of numbering; they numbered everything. The silent policeman which stood at the corner of "Positive 2 St." and "Positive 1 Ave." was marked that way. Half way between Positive 2 St. and Positive 3 St. there was a garage which set back about two-tenths of a block from Positive 1 Ave. The Council numbered it and called it "Positive 2.5 St. and Positive 1.2 Ave." Most of the people spoke of it as "Plus 2.5 St. and Plus 1.2 Ave." Sometime later there was an election in the city and a new Council was elected. The members were mostly young electricians and the new Highway Commissioner was a radio enthusiast. At the first meeting the Council changed the names of all the avenues to "Mil-amperes"[3] and of all the streets to "Volts." Then the Highway Commissioner who had just been taking a set of voltmeter and ammeter readings on an audion moved that there should be a new road known as "Audion Characteristic." He said the road should pass through the following points: Zero Volt and Plus 1.0 Mil-ampere Plus 2.0 Volts and Plus 1.7 Mil-amperes Plus 4.0 Volts and Plus 2.6 Mil-amperes Plus 6.0 Volts and Plus 3.4 Mil-amperes Plus 8.0 Volts and Plus 4.3 Mil-amperes And so on. Fig. 21 shows the new road. [Illustration: Fig 21] One member of the Council jumped up and said "But what if the grid is made negative?" The Commissioner had forgotten to see what happened so he went home to take more readings. He shifted the battery clip along, starting at _c_ of Fig. 22. At the next meeting of the Council he brought in the following list of readings and hence of points on his proposed road. Minus 1.0 Volts and Plus 0.6 Mil-ampere " 2.0 " " " 0.4 " " " 3.0 " " " 0.2 " " " 4.0 " " " 0.1 " " " 5.0 " " " 0.0 " " Then he showed the other members of the Council on the map of Fig. 23 how the Audion Characteristic would look. [Illustration: Fig 22] There was considerable discussion after that and it appeared that different designs and makes of audions would have different characteristic curves. They all had the same general form of curve but they would pass through different sets of points depending upon the design and upon the B-battery voltage. It was several meetings later, however, before they found out what effects were due to the form of the curve. Right after this they found that they could get much better results with their radio sets.
