This country was an industrial country. The industry was beginning its initial prosperity. The western city was a highly industrialized area. Mr. Spencer worked in a factory there. Because he believed success came from industry, he was very industrious. He had an inherent interest in induced current and in the induction field. Mr. Spencer developed an infrared medical tool. He inferred from the market survey that it had great market value. Mr. Spencer informed his boss of the important information. His boss was rather influential in the government circles. Though the boss worried the inevitable inflation could influence the factory, he encouraged his inferiors to produce the new product. Even though hard work induced tiredness; Mr. Spencer had no feeling of inertia. No one could induce him to leave his office except his son, a lovely infant, Mr. Spencer researched the ingredients of the infant's food. He kept his son from the infectious flu. He taught him the initial letter of the word "London" was L. Teaching infants took infinite patience. Fortunately, his son inherited the father's' ingenious mind. Sometimes they drove out to a hill. The car would move faster and faster down the hill because of inertia. And the boy often broke into an infectious laugh. The family lived a district thickly inhabited. The inhabitants there all liked this little boy.
