After lunch Mr. Bodmer again went to Easton and down the Delaware (on the interesting route we had recently taken) to draw several scenes and to complete his work, including the picturesque Delaware Gap, the sketch of which he had not yet finished. He was also supposed to inspect the interesting boulder passage behind Easton and to make an interesting sketch there. For this purpose he had a gig (cabriolet), which he drove himself. The rest of us took a walk in the afternoon to the vineyard. 
There we found that the grapevines on these elevations had quickly grown tall. They had been planted in ditches in two rows, which were richly supplied with manure. This so-called Alexander grape seems to me to have originated in America; at least, I have found its leaf to be very different from that of our wine grape; its origin is not precisely known. The wine that I drank from these grapes is sour and has a light-red color. But this is the first attempt, and one cannot yet pass judgment on it. Near the vineyard a profusion of Syngenesia were now in bloom: Eupatorium, aster, Solidago, and others. Verbascum already had ripe seeds, and Senecio hieracifolius literally covered a recently cleared field before the forest. Mr. Moser and Mr. Wöhler later went out to the Lecha islands, where they had seen a large flight of wild doves. They returned from the first two islands with a squirrel (Sciurus hudsonius Linn.). They had shot a dove but had not retrieved it.
