HAWKEYE MINING COMPANY. In 1866 Platt SMITH, General Vandever, and a Mr. Stevenson announced plans to reopen a LEAD mine on the property of Lucius Hart LANGWORTHY that Mr. Langworthy had first operated. Langworthy remembered that with the aid of two men he had removed $7,000 worth of lead in one day.
The lead deposits remaining were underwater. To remove the water, the investors obtained a steam engine that could raise 360 gallons per minute.
