Boghead Coal

Boghead coal is a variety of bituminous or sub-bituminous coal that looks and burns much like cannel coa . It is made up largely of the remains of algae water plants that form the greenish or brownish scum you often see on fresh water ponds and reservoirs in summer and fall. It is rich in volatile hydrocarbons that produce illumining gas. When distilled, it yields a great deal of tar and oil. Like cannel coal, it is usually found in small deposits or lenses.
