the navigation of this stream, and in 1771 passed a law for its improvement. Subsequent laws for the same object were enacted in 1791, 1794, 1798, 1810, 1814, and 1816, and a company had been formed under one of them which expended upwards of thirty thousand dollars in clearing out channels, one of which they attempted to make through the ledges of slate about seven miles above Allentown, though they soon relinquished the work.</ref> Eventually, the owners sold some coal to Josiah White and Erskine Hazard, who operated a wire mill foundry at the Schuylkill River falls near Philadelphia. White and Hazard were delighted by the quality of the fuel, and subsequently bought the LCMC's final two barges to survive the trip down the Lehigh. Convinced they could much improve the reliability of its delivery, they began in 1815 to inquire after the rights to mine the LCMC's coal and hatched a plan to improve the navigation on the Lehigh as a key step. Lehigh Coal Company White and Hazard very shortly found themselves on the receiving end of investor criticisms that the improvements and mining operation at Summit Hill were failing and were both considered crackpot schemes. The majority opinion was that improvements were possible, but that coal mining was less likely to succeed. Accordingly, they secured additional investors by forming two companies, the Lehigh Coal Company (LCC) and the Lehigh Navigation Company, and began seeking legislative approval for improving the Lehigh River's navigation. In 1817, they leased the Lehigh Coal Mine's properties and took over operations, incorporating it on October 21, 1818, as the Lehigh Coal Company. They petitioned the legislature and proposed acquiring rights to make improvements to the Lehigh River for which there had been a string of supportive legislation going back decades. In 1820, White and Hazard bought out their partner Hauto and dissolved the Lehigh Coal Company on April 21, 1820. White and Hazard found a wide divergence of opinion on whether the Lehigh River could be tamed, and even fewer believed that the mining of coal from the Lehigh River's surrounding lands was feasible. On three separate occasions, funds were raised to improve the Lehigh River's functionality. By 1820, the two companies had a marginal level of navigability on the Lehigh over four years ahead of their targeted 1824 deadline. Coal was transported by mule track from Summit Hill to a loading chute
