Swimming is forbidden
From the 1884 “Albany Hand-Book, A Stranger’s Guide and Residents’ Manual”:
“Swimming in the river near the shores or wharves, between 6 A.M. and 8 P.M., is forbidden by city ordinance. Still, if a man falls overboard, he better swim if he knows how, rather than break the law and go to the bottom. The fine is only $1.”
