“While these delays affected us, they did not interfere with the progress of the monitor which was building in Boston; but when this vessel was launched, she sank to the bottom from lack of buoyancy, and a halt was called on the nineteen other vessels. “These vessels had been constructed on very vague plans and conditions. Mistakes were made in the original design, and weights added without investigating the correctness of the original sketch, which, with the so-called ‘calculations,’ were furnished by Mr. Ericsson; at least they had been examined, approved, and signed by him. They were not furnished to bidders. “The day after this launch, the ‘Monitor Ring’ was in a state of collapse! Mr. Lenthall and Mr. Isherwood now reasserted their proper authority. They ordered Mr. Stimers and Mr. Allen to reduce the weights in the turrets, and wherever else it was possible to do so sufficiently to make the vessels float. “These reductions in equipment, outfit, etc., were communicated to the builders at Chester, before they launched the ‘Tunxis’; but these vessels, by the reductions, were rendered entirely useless for their designed service, or any other. “Finding that the Boston vessel and the ‘Tunxis,’ built at Chester, notwithstanding the alterations, lacked efficiency to a serious degree, they decided to rebuild most of the others by deepening them, and the whole matter was placed in my hands by Chief Engineer King, who with some others were designated by the Secretary of the Navy to investigate and prepare plans for the deepening, and to ascertain the cost of the alterations. “After a careful investigation, I found it would be necessary to increase the depth of the hulls about thirty-three inches, involving the necessity of raising the solid oak decks to that extent with the hull proper, and the armor backing and armor which had to be taken off and replaced. “A so-called expert was detailed to assist me in my calculations, but, having no use for him, I did not avail myself of his services.
