The first thing now to be done was evidently to remove the broken iron plates, and to rivet in new ones in their place. In order to provide for additional strengthening of the vessel inside, the large timbers which had been purchased were made use of, as being exactly adapted for the purpose. Three of these were placed across the angle-irons against the side of the vessel, the longest and stoutest, which was twenty-three feet in length, one foot broad, and six inches thick, being placed highest up, about two to three feet below the deck. This was secured in its place by bolts, each a foot long, which were run through the ship's side, one at the centre of the space between each of the angle-irons. As there would, however, be a space left between the face of the beam and the side of the vessel, except at those points where it rested upon the angle-irons, this interval was filled up with well-seasoned red pine, which added very much to the solidity of the contrivance. To "make assurance doubly sure," two other beams, of the same depth and thickness, but not of the same length, and secured in a similar manner, were also employed. By this means, it is very evident that the ship was made a vast deal stronger than she ever was before, though not stronger than was proper for her size and shape. The whole length of the new plates put in the ship's sides was eight feet two inches; and so effectually was the work done that the whole of it remained perfect, stringers and all, at the end of two years and a half of severe and uninterrupted service. These contrivances added very little to the weight of the vessel, and gave it very great support in the weakest part, and just where it was most required, to enable her to carry coals on deck, &c.
