Having explored Indian burial sites on the islands of the river and inspected local artifacts collected by Dutot and others, Maximilian and Bodmer left Dutotsburgh on the morning of August 25, arriving at Sach's public house that same evening. Nearby was an older building, the first to have been occupied by the man whose father had come to North America from Saxony. Sometime on the 25th or 26th, Bodmer made a sketch of Sach's first dwelling, no longer in use when Bodmer saw it.

On September ro, Maximilian began the supervision of the packing of five large cases of natural history specimens at Bethlehem for shipment abroad. The next day Bodmer arrived from Mauch Chunk with additional studies of that area, including a watercolor describing the location in the Mahoning Valley of the former Moravian settlement of Gnadenhutten. Maximilian had earlier visited this site, referring to it in his journal on August 31 as having been settled by a group of religious brethren from Herrenhut in the middle of the eighteenth century.

Leaving Dreidoppel in Bethlehem to prepare and pack zoological specimens, Maximilian and Bodmer took a carriage to Mauch Chunk on August 23, stopping briefly at a settler's house beyond Bethlehem to send back for Bodmer's forgotten sketching case. In the afternoon they stopped again at a public house in the vicinity of the Delaware Gap.

A busy commercial center, Helvoet was situated on either side of a shipping chanel used by merchant craft and warships of the Dutch Navy. Farms and gardens occupied the surrounding lowlands. Again on May 16th, Bodmer sketched a view of a farmer's house during an afternoon excursion into the countryside.
