Example text

In the South, forests were cleared for cotton, tobacco, and other crops. USE OF THE FOREST FOR FUEL The volume of wood used in 1850 was almost six times the volume of fifty years earlier. By mid-century, wood still supplied more than 90 percent of the nation’s heat energy needs; domestic heating and cooking accounted for the largest use of wood fuel (see Figure 7). The increasing scarcity and expense of fuelwood spurred innovations in the form of cast-iron wood stoves, which were four to six times more efficient in the use of wood than fireplaces.

WESTWARD EXPANSION & EASTERN INDUSTRIAL GROWTH 19 1800s, railroads accounted for 20 to 25 percent of the country’s total consumption of timber. By far the most significant railroad use of wood was for crossties. Each mile of track required more than 2,500 ties. Crossties were not treated with preservatives until after 1900, so because of their rapid deterioration in contact with the ground, they had to be replaced every five to seven years. Given the miles of track in 1910, that would be equivalent to replacing the ties on some 50,000 miles of track annually.

More efficient new products such as plywood and various panel products were developed. Statistics reflect these changes in technology. S. production of solid wood products consumed. By 2007 plywood and other panel product’s share had risen to 16 percent. Expanded use of preservative treatments also reduced the demand for wood. By 1920 virtually all crossties were being treated, and by 1960 railroad use of wood had dropped to one-fifth of what it had been in 1900. STABILIZATION OF FOREST AREA By the 1920s, a change occurred that was little recognized or commented upon at the time.
