During a steamship's stay in port the three chief divisions, sailing, engineer's and steward's, are under the jurisdiction of shore officials whose officers are on the deck. The sailing department is responsible to the marine superintendent, the engineer's to the superintending engineer and the steward's to the port steward. Thus the vessel while in port has no direct communication with the company's office, the dock superintendents acting as intermediaries. When stores are sent to the ship they are addressed to the department for which they are intended. The port steward controls the direct purchasing of provisions and is supposed to buy in the cheapest and best market. The marine superintendent and superintending engineer furnish the other materials required. Should provisions be found unsatisfactory when received the chief steward sends them back, and in such action is always upheld by the port steward. The cargo is in charge of the sailing department and is received and stowed under the direction of a boss stevedore selected by the dock superintendent. Even the fleetest ocean steamships carry considerable cargoes, and to those unfamiliar with it the process of loading a vessel is a sight full of interest. On the wharf assorted merchandise by the carload is being lifted from vans and piled near the ship, and teams by the score are adding their quota to the immense mass, while on the water side lighters laden with more merchandise are either fastened to the vessel's side or anchored close at hand waiting to hoist their contents aboard. Engines are puffing, ropes are tugging and derricks lifting heavy freight of every kind to the ship's deck, the orders of the stevedore and the answers of his men mingling with the general din. Large vessels have four or five holds and much skill is required to properly stow the cargo in them, grain, from its compact and dead weight, being mostly reserved for the center of the vessel, while cured provisions are packed as far forward and aft as possible for their better preservation from the heat of the ship's fires. In many vessels carrying passengers as well as freight the heaviest weight is stowed in the lowest hold; this is to steady the ship and is called in the argot of the stevedore "stiffening" the ship. It requires about 1,500 tons to "stiffen" an ocean steamship of the largest size, and when this is done the hold is battened down and work begun on the next.
