On Thursday, 11 May 1882, barely a month before this cartoon ran in Puck magazine, my maternal Great Grandfather, Edmund Theodore Schletter arrived at Castle Garden immigrant landing depot aboard the S.S. Westphalia.

Throughout the period of mass immigration, New York City was the principal point of immigrant disembarkation. For 35 years this was at Castle Garden on Manhattan. The prevalence there of various cheats and swindlers was one of principal arguments for the development of Ellis Island in 1892.

Today the facility is Castle Clinton National Monument in Battery Park on the tip of Manhattan.
