From the 14th to the 20th centuries,
ports around the world carried out official quarantines of arriving travelers
in hopes of staving off epidemics of plague, yellow fever, and other deadly
scourges. The caption to this drawing from an 1858 issue of Harper's
Weekly quotes a Dr. Anderson as saying: "While the Angel of Death rides
on the fumes of the iron scow, and infected airs are wafted to our shores from
the anchorage, we shall have no security against these annual visitations of
pestilence."
