The effects of capital, operating and debt cost variations on project performance criteria are examined using a theoretical model and an actual case history. On an after-tax basis, financial measurements are found to be most sensitive to operating cost changes, somewhat sensitive to reasonable changes in capital costs and relatively insensitive to interest rate fluctuations.

A unique freeze conditioning agent (FCA) which functions by forming structurally weak ice rather than suppressing the freezing point of water has been successful in alleviating frozen coal problems. Frozen coal treated with FCA has been quickly unloaded at temperatures below -17.8°C (O°F). Other applications of FCA include deicing: conveyor belts, idler, idler arms, and other moving parts that have been impeded by ice.

Beall: Mr. Donovan, would you tell me something about your early life, leading up to your going into I he mining industry? Donovan: I was born in St. Charles, Minn., on November 18, 1879. At that time my father was a school teacher, but he later entered the Congregational ministry. He was pastor in several small Minnesota towns, so we moved about quite a bit.
