The Olivier Van Noord, a Dutch East Indiaman, Captain Kicoyt, lying in the Salt-house Dock, Liverpool, has her lower masts constructed of ironplates formed into cylinders, and firmly rivetted together. Inside, at various intervals, are cross-bars to maintain the shape of the cylinders, and to prevent bulging or other injury.
