Stevedores worked inside the ship, packing and securing the merchandise. Dock workers and longshoreman worked on the docks moving merchandise from the ship to the docks and vice verse.

The port of New York, which included the docks in Brooklyn and Hoboken, was one of the busiest ports in the world in the mid to late 1800s and early 1900s when Johann Bernard Petermann, Fritz Kettler and Johannus Jensen (the first and second husbands of Hannah Peters) worked on the docks in Brooklyn and Hoboken.

Excerpts from Harper's Weekly September, 1877, THE LADING OF A SHIP

Unloading

The unloading, once begun, proceeds rapidly, as any men being employed as can work together conveniently, and the freight being hoisted out by means of tackle suspended from the yard-arm, and operated by steam or horse power. Usually, as fast as it is discharged, the cargo is sent to warehouses near by, and assorted for the owners.

The longshore-men are among the most ignorant and brutal of men. Their work is very laborious, but requires little skill; their surroundings and associations are all such as tend to degrade them; their pay is smaller than that of almost any other class of workmen, and their prejudices are easily excited. It thus happens that debauchery and murderous fighting are constant among them; extensive strikes against reduction of wages or some fancied imposition are of frequent occurrence; and some of the bloodiest riots New York has ever seen originated among them. Intemperate and brutal in every respect, yet hard workers, and consequently muscular, no class of men gives the police so much trouble as the 'ongshore-men.

The ease with which exceedingly heavy bodies are handled by the stevedore's men is remarkable. The hatchways are often just large enough to let the package through, and frequently the space between decks is so circumscribed that the men have hardly room to move; yet by skillfully landing the hogshead, or boxed piano, or granite monument, or huge piece of machinery, as it is lowered to them by the tackle, by bringing it up and twisting it over with iron bars, pulling it with cotton hooks, and pushing it with brawny hands and shoulders, sitting down four or five in a row, against a bulkhead shoving with their feet, they slowly work the unwieldily mass into its corner, and brace it firmly by wedges; until its successor is placed.

"A word about the lighters. They are broad, blunt-nosed, sloop-rigged boats, all deck except a little hole of a cabin, and used about the harbor for transporting merchandise to and from vessels at anchorage, or from wharf to wharf. They are thoroughly ill-looking, always in the way, and only to be excused for existence on the score of the great usefulness. The lighters are on the rivers what the carts are on the streets."

SCENE ON THE GREAT FLOUR DOCKS, COENTIES SLIP, EAST RIVER, NEW YORK

Coenties Slip was located in lower Manhattan.

Unfortunately, the accompanying article was not included with this image. However, I believe that the men with the T shaped devises on the left are inspecting the flour. There were laws regulating the quality or grade of the flour to insure that it would make a decent bread. The barrels were inspected to determine that they were constructed according to regulations to protect the flour from moisture and bugs. They barrels were also weighed.

I do not know why there are women and children on the dock. They appear to be working at something and may be helpers of the flour inspectors.
