Fifth-graders from PS 194 in Sheepshead Bay, Brooklyn, repeated the cries that once echoed around the busy port of New York as they raised the sail on an 1885 cargo ship during a class trip to Manhattan’s South Street Seaport Museum on Oct. 7.

Kids are kids, whether the calendar says 1890, 1910 or 2019.
