Edge describes the traditional methods and aims of historical geography, then goes on to describe briefly the methodological changes in the discipline. Edge introduces the work of Alan Pred in the ...historical geography of the United States and in particular on the growth of American cities. He describes Pred's model for urban growth and explains its principles. The model is animated to show the first cycle. Attention is now turned to the second cycle of Pred's model. Once again it is animated to illustrate Edge's verbal description. Edge now briefly goes over the nineteenth century changes in the American city which Pred's model attempts to explain. Tables of statistical data are projected to illustrate Edge's voiceover. These data are now related to individual cities. Edge illustrates the growth of American cities in the period 1860-1900 (approx.) with a number of examples. A map of the States locates the cities used as examples. Edge now returns to Pred's model in order to examine it in greater detail and to test it against known facts. The multiplier aspect is first examined in detail in particular in its impact on the service activities of a city. This is followed by a detailed examination of the threshold concept. Diagrams of the model are employed to illustrate the analysis. Attention is now turned to the concept of the model which deals with the relationship between urban growth and invention. Edge goes on to explain reasons for differences in growth rates. Edge now considers the transport changes during the period 1860-1900 using New York as a point from which manufactured goods were shipped inland. A diagram is used to illustrate the easing of transport problems during the four decades. The development of the American railway system is outlined. Shots of rolling stock. Comparative maps 1840-1900 are used to illustrate the development graphically. Edge now turns to the future and considers how far the Pred model of city growth is valid for the future growth of cities. He suggests ways in which the model, although historically accurate for the nineteenth century in the U.S.A., may require amendment in order to be valid still by the year 2000. Diagrams are used to show that the model still applied to growth in the mid-twentieth century. Credits.
