For thirty years they had disappointments, as nobody would use the coal, which cost about $14 per ton to transport to Philadelphia. To cheapen this, efforts were made to improve the navigation of the Lehigh, out of which grew the canal which was the early route of the coal to that city. Asa Packer once said that in 1820 three hundred and eighty-five tons went to Philadelphia, and this choked the market. In 1827, when the mining at Summit Hill had got a good start, the

Switchback gravity railroad was built to bring the coal out from the mines to the river at Mauch Chunk. The loaded coal cars ran by their own momentum nine miles down a grade of about ninety feet to the mile. To get the cars back, they were hauled up the inclined plane on Mount Pisgah, then run by gravity six miles inland to Mount Jefferson, where they were hauled up a second plane, and then they ran three miles farther by gravity to the mines. This route was used for many years, but was afterwards superseded by another railway, and now the famous
