One of the wisest acts of Henry the Eighth was making the sea-service a regular profession--though long after his time ships, and even fleets, were commanded by men who had hitherto lived and fought only on shore. About the year 1545 port-holes were generally introduced on board the larger ships. Before that time the guns were fought over the bulwarks, or were alone placed on the forecastle, and the aftercastle, which latter portion of the ship is now called the poop. This word _poop_ is evidently derived from the Latin _puppis_, as originally the after-part of a ship was called by the Romans, and thence the name was given to the ship herself, a part being taken for the whole. The ports were, however, placed not more than sixteen inches from the water, so close, indeed, as greatly to peril the ship. It was in consequence of this faulty construction that the _Mary Rose_ of sixty guns, one of the largest ships in the British navy, heeling over to a squall while encountering the French at Spithead, was capsized, when her captain, Sir George Carew, and upwards of 500 of his men, perished in the waves. As late as the year 1835, Mr Deane, by means of his ingenious invention, the diving-bell, was enabled to recover several guns, parts of the wreck, and some stone-shot of the _Mary Rose_. Ships generally carried but few guns. A writer, describing a battle which took place off the Isle of Wight, and which lasted two hours, when upwards of ninety ships were engaged, speaks of 300 shot being fired, to prove how desperate was the contest. I have before me an account of the battle in which the _Mary Rose_ was lost, not, as the French say, in consequence of their fire, but because it was attempted to keep her ports open when a considerable sea was running, and a strong breeze had suddenly sprung up. The French king had sent over a large fleet to annoy the English coasts. Henry, hearing of the expedition, hurried down to Portsmouth to hasten the equipment of 100 sail, which he had ordered to be got ready. The French appearing, the English sailed out to Saint Helen's to meet them. A squall came on, and the _Mary Rose_ foundering, the _Great Harry_ which was attacked by the French row-galleys, bore the brunt of the action. The French quickly retired, though they attempted to make a lodgment on the Isle of Wight, but were compelled to return to their ships. The English are described as using pinances, which are vessels of great length and little beam, moving very rapidly, and fitted both with sails and oars. We hear, also, that the _Carracon_ the ship of the French Admiral, was destroyed by fire before the fleet left their coasts. She is described as appearing like a castle among the other ships of the fleet, and so strong that she had nothing to fear at sea but fire and rocks. It is stated that she had 100 brass cannon on board; but as she was not more than 800 tons burden, they must have been very small ones.
