We cannot predict what improvements will be made in mining technology that would allow the recovery of more of the coal than is currently achieved. We cannot evaluate with certainty what tolerance coal consumers might have for using coal of lower quality than is now typically used. Finally, it is difficult to predict the rate of coal utilization by extrapolating historical data. Annual coal
