Eventually, he convinced his brothers Charles and Maurice to come along with him and see for themselves. Starting in 1812, they began buying and mining large tracts of inexpensive land. They were able to extract several tons of anthracite at a time, but lost most of what they tried to bring back to Philadelphia due to the treacherous waterways that were the main method of transportation in the interior. While the southern reaches of the Coal Region were already beginning to supply Philadelphia, they realized that the areas they had been exploring and mining were well-positioned to deliver coal to New York City, which had experienced an energy crunch after the War of 1812, when restrictions were placed on the import of British coal. Inspired by the new and successful Erie Canal, they envisioned a canal of their own from Pennsylvania to New York, through the narrow valley between the Shawangunk Ridge and the Catskill Mountains, to the Hudson River near Kingston, a route followed by the Old Mine Road, America's first long-distance transportation route.
