 Bartholomew relate that in 1823 White and Hazard offered to pay for improved navigations over the distance of the Delaware and Brenckman adds in 1822–23 they had tested four large canal locks suitable for Steam tugs (such were in wide use by then) to pull Schooners to navigate up the river to Easton, where they would build matching 300 feet locks allowing sea going ships access to Mauch Chunk.
