This last quotation, belonging to the twelfth century, has reference to the mode of fighting which was in vogue during the Middle Ages, when the fighting tops, the castellated structures at both bow and stern, were such significant features on these long, narrow ships. The word “keel” is used not, of course, in reference to any particular portion of the ship’s structure, but to the ship as a whole. The word is still in active use to-day on the Humber as applied to a species of craft which, with its large squaresail as its only canvas, bears some similarity to the old Norse _ceols_ or keels. [Illustration: VIKING SHIP WITH AWNING UP READY FOR THE NIGHT.] The crews of these ships slept under those “tilts” or awnings which were spread across the ship in an inverted V-shape. In harbour the tilts were spread over the entire vessel. But in less sheltered anchorages, and when at sea, tilts were rigged over only portions of the ship to afford sufficient protection to the men. But in all cases these _tilts_ or _tjalds_ were struck before the ship went into action, for the obvious reason that it was desirable to have the entire ship clear for fighting. The food-supplies, both solid and fluid, were carried in casks, and the mess system is well described in one of the Sagas entitled “The Story of the Ere-Dwellers.” “In those days,” runs the narrative, “was it the wont of chapmen to have no cooks, but the messmates chose by lot amongst themselves who should have the ward of the mess day by day. Then, too, was it the wont of all the midshipmen to have their drink in common, and a cask should stand by the mast with the drink therein, and a locked lid was over it. But some of the drink was in tuns, and was added to the cask thence as soon as it was drunk out.” We know nothing as to whether these Norse ships possessed bilge pumps. The probability is that they did not, but a bailing butt was certainly part of their inventory. Evidently there was a well some distance aft, into which any water shipped was allowed to drain and thence bailed out, as the reader shall presently see from the following quotation. The description refers to the time when King Harald manned his new dragon-galley. “The said dragon he manned with his court-guard and bareserks,” runs the Saga. “The stem men were the men most tried, because they had with them the king’s banner; aft from the stem to the bailing place was the forecastle, and that was manned by the bareserks. Those only could get court-service with King Harald who were men peerless both of strength and good heart and all prowess; with such only was his ship manned.”
