Within the next two years, White and Hazard constructed a descending navigation system that used their unique "bear trap" or hydrostatic locks, which allowed the passage of coal boats by means of artificial floods. The coal arrived at the head end from the mines at Summit Hill or down along the steep mule trail from near the headwaters of Panther Creek. It floated down the navigation; at journey's end, the barges were sold as fuel or for Delaware basin transports. The navigation company began shipping significant quantities of coal by early 1819, ahead of expectations, and attained their goal of regular shipments in 1820.<ref name=HistCC02> </ref> In 1820, the company was combined with the Lehigh Coal Company with the ouster of George Hauto, but was not rechartered officially until 1822. Lehigh Coal & Navigation Company By late 1820, four years ahead of their prospectus's targeted schedule, the unfinished but much improved Lehigh Valley watercourse began reliably transporting large amounts of coal to White's mills and Philadelphia. The nearly 370 tons of coal brought to market that year not only salved the winter's fuel shortage but created a temporary glut. After buying out co-founder George Hauto, White and Hazard reworked their lease deal with the Lehigh Coal Mine Company, and merged it with the Lehigh Coal Company, acquiring ownership of its 10,000 acres spanning three parallel valleys in the from Mauch Chunk to Tamaqua. A few months later, they merged the LCC and the Lehigh Navigation Company. In late 1821, they filed papers to incorporate Lehigh Coal & Lehigh Navigation, which took effect in 1822. Non-mining Ventures Under both White and Hazard, as operations managers from 1822 through 1865, Lehigh Coal & Navigation Company was a company constantly looking for innovative solutions to increase business and revenues. The vertical integration many economists credit them with inventing would appeal to them as a very natural way to control costs, hence maximize profitability. The two, and the various members of the corporate board often heard of ideas that separately(?) or together needed financial investment which the company would often join as investors, and often end up providing a later critical boost of finishing financing, investing in such ventures directly, or buying out at a later time as subsidiaries as things developed a proof of concept, track record, better promise, or dependency on another business.
