Excerpt from Knowledge for the Time: A Manual of Reading, Reference, and Conversation on Subjects of Living Interest, Useful Curiosity, and Amusing Research The precise and best mode of constructing Iron Ships-of-War, so as to carry heavy guns, is an interesting problem, which Captain Coles believes he has already satisfactorily solved in his Turret ship, wherein he proposes to protect the guns by turrets. Captain Coles offered to the Admiralty so long ago as 1855 to construct a vessel on this principle, having a double bottom; light draught of water, with the power of giving an increased immersion when under fire; sharp at both ends; a formidable prow; her rudder and screw protected by a projection of iron; the turret being hemispherical, and not a turn-table, which was unnecessary, as this vessel was designed for attacking stationary forts in the Black Sea. Captain Coles contributed to the International Exhibition models of his ship; admitting (he states) from 7 to 8 degrees depression. In two this is obtained by the deck on each side of the turret sloping at the necessary angle, to admit of the required depression; in the other two it is obtained by the centre of the deck on which the turret is surmounted being raised sufficiently to enable the shot, when the gun is depressed, to pass clear of the outer edge of the deck.
