We don't know the provenance of this delightful newspaper ad posted at reddit. We can assume that it was published around 1865, as the young man was a fan of Andy Johnson, or president Andrew Johnson, who served from 1865 (upon the death of Lincoln), was impeached in 1868, and remained in office until 1869. For an 18-year-old, the writer seems to have his life together, but was probably working too hard so far to meet many young woman. When he says he wants to buy waterfalls, he is most likely referring to a waterfall bustle, as was the style at the time. I would bet that he got responses to this ad. The last line makes him seem cute as well as successful.
