from The Century Dictionary and Cyclopedia
- n. The interior structure is made up of water-tight transverse and longitudinal bulkheads arranged to form a number of compartments or tanks in which oil, molasses, or other fluids can be carried in bulk. The top of the tanks is a water-tight deck, above which and opening into the tanks are expansion-trunks (which see). The fluid is pumped into and out of the tanks by a system of pipes and steam-pumps. In tank-steamers the machinery and boilers are separated from the oil tank-compartments by a coffer-dam formed by two complete transverse bulkheads about 4 feet apart, which is frequently filled with water. Also colloquially called tanker.
- n. A ship of which the hold is so arranged that oil or other liquid can be carried in bulk.

Schwalbe, who, as the submarine ranged up half a cable's length to leeward of the tank-vessel, had left the shelter of the conning-tower and was standing on the platform in its wake.
He also knew that the submarine would have to be constantly under way during the boarding operations, otherwise the tank-vessel, offering considerable resistance to the wind, would drift down upon U75, whose leeway was almost unappreciable.
Less than five hundred feet up, yet sufficiently far from the tank-vessel to enable the latter to screen her from the unterseeboot, was a large naval sea-plane.
The object depicted was that of a modern tank-vessel about four hundred feet in length.
