 Small-scale agriculture in its early years supported dozens of towns and dispersed rural communities, many of which no longer exist as a result of transportation and economic changes.After construction of railroads, those towns bypassed by rail service, such as Carroll, Carwile, Keith, and Timberlake, did not prosper for long.Restructuring of the railroad industry in the late 20th century resulted in abandonment of other lines, and towns such as Ingersoll and Driftwood, for example, had declining populations that made it difficult to sustain educational and city services.
